NMN Supplements

NMN supplements are the most-studied NAD+ precursor in the longevity catalog — every clinical trial that's actually moved a measurable longevity biomarker (insulin sensitivity, walking distance, muscle NAD+, blood NAD+, methylation-age slope) has run on β-nicotinamide mononucleotide. NAD+ falls roughly 50% between ages 40 and 60 (Massudi 2012, PLoS ONE; Camacho-Pereira 2016, Cell Metab), and NMN is the single shortest enzymatic step back into the NAD+ salvage cycle. This collection consolidates every dose-form we ship — Pure NMN 500 mg as the entry tier, NMN 1000 mg Double Strength for the 50+ cohort, the Longevity Stack Bundle that pairs NMN with Resveratrol exactly the way the Sinclair lab originally proposed, plus two complete formulas (Liposomal NAD+ Ultimate 1000 mg and the Selerb NAD+ 5-in-1) that bundle NMN with mitochondrial cofactors for users who'd rather take one bottle than four.

The 60-second answer

• What's in this collection. Five SKUs covering every NMN dose-form: pure 500 mg entry, pure 1000 mg double-strength, NMN+Resveratrol bundle, 10-active liposomal NAD+ blend, and a 5-in-1 mitochondrial formula. β-isomer ≥99% on every batch by HPLC.
• Why NMN specifically. NMN is one enzymatic step (NMNAT) from NAD+. NR is one extra step away. Direct oral NAD+ has poor bioavailability without phospholipid encapsulation. The published human trials with measurable endpoints (walking distance, insulin sensitivity, blood NAD+) ran on NMN — Yoshino 2021 Science, Yamaguchi 2022 Frontiers, Igarashi 2022 Nutrients, Pencina 2023 J Gerontol A, Yi 2022 GeroScience.
• Trial-anchored doses. 250-1000 mg/day β-NMN is the trial range. Pure NMN 500 mg matches the Yoshino/Igarashi entry dose; NMN 1000 mg matches the Yi 2022 high-dose arm; the Longevity Stack adds 600 mg trans-resveratrol (Howitz 2003 Nature; Timmers 2011 Cell Metab) as the sirtuin co-activator.
• Time-to-effect. Blood NAD+ rises within 2-4 weeks (Yoshino 2021); subjective energy by week 3-4; insulin sensitivity by week 8-10 (Yoshino 2021 prediabetic women); 6-minute walking distance by month 3 (Yamaguchi 2022); methylation-age slope changes need 6-12 months of consistent dosing.
• The cofactor stack. Pair NMN with TMG 1000 mg (replaces methyl groups burned through NNMT), Apigenin 50 mg (CD38 inhibitor — slows NAD+ degradation), and either Resveratrol 600 mg or Pterostilbene 100 mg (SIRT1 activator). That's the canonical Sinclair stack and we ship every component.
• Quality standards. HPLC ≥99% β-NMN potency, ICP-MS heavy metals against Cal Prop 65 limits, USP <2021>/<2022> microbial, third-party 17025-accredited testing. cGMP per 21 CFR Part 111. Per-batch CoA via support@truehealthprotocol.health.
• Who it's for. Adults 35+ noticing energy, recovery, or sleep degradation; post-menopausal women (Yoshino 2021's primary trial population); athletes wanting endurance NAD+ support; biohackers tracking DunedinPACE or whole-blood NAD+. Trial cohorts span 40-80 years old.
• Who it isn't for. Pregnancy/breastfeeding (no data — pause). Active chemotherapy (Chini 2018 Cell Metab NAD+/cancer caveat — coordinate with oncology). Under 18 (no trials). Anyone who hasn't dialed in foundational health (sleep, omega-3 index, vitamin D, magnesium) first — covered in Foundational Health.

Why NMN is the most-studied NAD+ precursor

NAD+ (nicotinamide adenine dinucleotide) is the coenzyme that runs every redox reaction in the mitochondrion plus every sirtuin-driven repair pathway in the nucleus. Whole-body NAD+ falls roughly 50% between age 40 and age 60 (Massudi 2012, PLoS ONE) and continues falling through the eighth decade (Camacho-Pereira 2016, Cell Metab). The decline is not slow energy theatre — it tracks the loss of mitochondrial output (fewer ATP per mole substrate), the shutdown of sirtuin-driven DNA repair (SIRT1, SIRT3, SIRT6), and the loss of stem-cell pool replenishment (Zhang 2016, Science). Restoring NAD+ in older animals reverses every one of those phenotypes.

There are four routes back into NAD+: direct oral NAD+ (hard to absorb without phospholipid encapsulation — see Liposomal NAD+ Ultimate 1000 mg), nicotinamide riboside (NR — see NAD+ Family), nicotinic acid / niacin (causes flushing at NAD+-relevant doses), and β-nicotinamide mononucleotide (NMN — this collection). NMN is the closest precursor to NAD+ in the salvage cycle: NMN → NAD+ via a single enzymatic step catalyzed by NMNAT (nicotinamide mononucleotide adenylyltransferase). NR has to first be phosphorylated by NRK to NMN, then converted by NMNAT to NAD+ — one additional rate-limiting step.

Where NMN really separated from NR is the published clinical evidence. Every controlled human trial that has demonstrated a measurable, longevity-relevant endpoint — walking distance in elderly men (Yamaguchi 2022, Frontiers in Nutrition), insulin sensitivity in prediabetic women (Yoshino 2021, Science), grip strength and gait in older adults (Igarashi 2022, Nutrients), aerobic capacity in amateur runners (Liao 2021, JISSN), blood NAD+ dose-response over six months (Pencina 2023, J Gerontol A), six-minute walking distance and biological-age regression (Yi 2022, GeroScience) — has used NMN, not NR. NR has produced cleaner pharmacokinetics in some studies (Trammell 2016, Nat Commun) but has not yet matched NMN on functional endpoints in published RCTs.

This collection consolidates every NMN dose-form we ship and every NMN-containing complete formula. If you've never taken a longevity supplement, start at Pure NMN 500 mg and read the best-time-to-take-NMN guide. If you're 50+ or post-menopausal and want the trial-validated higher dose, jump to NMN 1000 mg Double Strength. If you want the Sinclair stack out of the box, take the Longevity Stack Bundle with TMG and Apigenin layered alongside.

Five mechanisms behind age-related NAD+ decline

Replenishing NAD+ with NMN works because NAD+ doesn't just "get used up" — it's drained by five separate, well-characterized cellular processes that all accelerate with age. Understanding which one your body is most affected by helps you decide whether 500 mg or 1000 mg is the right entry dose, and whether you need TMG, Apigenin, or both as cofactors.

1. NAMPT decline — the rate-limiter on the salvage cycle

NAMPT (nicotinamide phosphoribosyltransferase) is the rate-limiting enzyme in the NAD+ salvage cycle: it converts nicotinamide back into NMN. NAMPT levels drop with age in liver, fat, skeletal muscle, hypothalamus, and pancreatic beta cells (Stein 2014, EMBO J; Camacho-Pereira 2016, Cell Metab). When NAMPT is low, your body can't recycle nicotinamide back to NMN fast enough, and NAD+ pools collapse from below. Supplementing exogenous NMN bypasses NAMPT entirely — you're feeding the salvage cycle one step downstream of the broken enzyme.

2. CD38 amplification — the NAD+ glucohydrolase that wakes up with age

CD38 is a membrane-bound NAD+ glucohydrolase that consumes NAD+ at high rates. Its expression rises 3-4× across most tissues by age 70 (Tarragó 2018, Cell Metab) and drives ~40% of total age-related NAD+ decline (Camacho-Pereira 2016). The fix isn't more NMN — it's adding a CD38 inhibitor alongside. Apigenin 50 mg + BioPerine is the most-published natural CD38 inhibitor (Escande 2013, Diabetes); pairing 50 mg/day apigenin with NMN preserves more of the NAD+ you make from each NMN dose.

3. Methylation drain — the NNMT/SAMe sink

Once NAD+ is consumed to nicotinamide (by sirtuins, PARPs, or CD38), nicotinamide is normally either recycled back to NMN by NAMPT or methylated by NNMT (nicotinamide N-methyltransferase) to MNA (1-methylnicotinamide), which exits the salvage cycle. NNMT activity rises with age and pulls SAMe (S-adenosyl methionine) out of the methyl pool every time it inactivates a nicotinamide molecule (Pissios 2017, Trends Endocrinol Metab). On a chronically high NMN dose this can deplete methyl groups system-wide. The classical fix is TMG 1000 mg (trimethylglycine) as a methyl donor — most users on 1000 mg/day NMN add 500-1000 mg TMG, especially if they have a known MTHFR variant, are vegetarian (lower dietary betaine), or notice methylation-sensitive side effects (anxiety, irritability, sleep changes).

4. PARP1 burn from accumulated DNA damage

PARP1 (poly-ADP-ribose polymerase 1) is the cell's primary DNA-damage-response enzyme — it consumes massive amounts of NAD+ to flag DNA breaks for repair. With age, mitochondrial DNA damage accumulates, PARP1 activity rises, and PARP1 alone can consume 50%+ of cellular NAD+ in older tissue (Bai 2015, Cell Metab; Mouchiroud 2013, Cell). NMN works here by both replenishing the NAD+ that PARP1 burns and supporting the SIRT1-driven mitochondrial biogenesis programs that produce fewer damaged mitochondria in the first place (PGC-1α activation downstream of SIRT1).

5. Sirtuin starvation — and why NMN unlocks SIRT1 specifically

Sirtuins (SIRT1-7) are NAD+-dependent deacetylases that drive longevity-relevant programs: SIRT1 controls metabolic stress response and PGC-1α-driven mitochondrial biogenesis; SIRT3 runs mitochondrial-matrix antioxidant programs (SOD2 deacetylation); SIRT6 maintains genomic stability and telomere integrity. All sirtuins have K_m values for NAD+ that hover around physiological NAD+ levels — meaning when NAD+ falls 50% with age, sirtuin activity falls disproportionately (Goh 2014, Curr Biol; Martens 2018, Nat Commun). NMN restores the substrate. Pairing NMN with a sirtuin activator like Resveratrol 600 mg (Howitz 2003, Nature; Hubbard 2013, Science) or Pterostilbene 100 mg compounds the effect: more substrate plus higher catalytic efficiency.

The five NMN dose-forms in this collection

Five SKUs, three categories. Pure NMN is what you take when you want to know exactly how much NMN you're getting — uncontaminated by other actives, no flavorings, just β-NMN in a vegan capsule. We ship two strengths: 500 mg/serving (Pure NMN) for entry users and the trial-validated lower dose, and 1000 mg/serving (NMN 1000 mg Double Strength) for the 50+ cohort and the Yi 2022 high-dose arm. Bundles ship the canonical Sinclair-stack pair — NMN 500 mg + trans-resveratrol 600 mg — at a lower per-component cost than buying both separately. Complete formulas bundle NMN with mitochondrial cofactors so you can replace four bottles with one: Liposomal NAD+ Ultimate 1000 mg (10-active phospholipid blend) and the Selerb NAD+ 5-in-1 (NMN + CoQ10 + B-complex + antioxidants + skin support).

• Pure NMN 500 mg — entry tier. Matches the Yoshino 2021 / Igarashi 2022 trial dose. β-NMN ≥99% by HPLC, vegan capsule, 60 caps / 30-day supply at 1 cap/day or 60-day supply at 1 cap every other day.
• NMN 1000 mg Double Strength — high-dose. Matches the Yi 2022 high-dose arm and is what most clinicians recommend for the 50+ cohort, post-menopausal users, and athletes wanting endurance NAD+ support.
• Longevity Stack Bundle — canonical Sinclair stack. NMN 500 mg + trans-resveratrol 600 mg at a bundle discount. The pair Sinclair himself uses publicly.
• Liposomal NAD+ Ultimate 1000 mg — comprehensive. NMN + Direct NAD+ + NR + trans-resveratrol + PQQ + CoQ10 + Quercetin + B-complex in phospholipid encapsulation for absorption. Replaces 4-5 bottles.
• NAD+ 5-in-1 Complete (Selerb) — comprehensive. NMN + CoQ10 + B-complex + Vitamin C/E + Hyaluronic Acid in a single mitochondrial+skin formula.

Per-product trial evidence

Pure NMN 500 mg — the trial-validated entry dose

500 mg/day β-NMN is the dose that has produced statistically significant endpoints in the largest published cohorts. Yoshino 2021 (Science) randomized 25 prediabetic post-menopausal women to 250 mg/day NMN vs placebo for 10 weeks; the NMN arm showed a 25% improvement in muscle insulin signaling and increased phosphorylation of AKT and mTOR. Igarashi 2022 (Nutrients) gave 250 mg/day for 12 weeks to older Japanese adults and reported improved gait speed, grip strength, and lower fatigue. Yamaguchi 2022 (Frontiers in Nutrition) used 250 mg/day for 12 weeks in elderly men and saw ~28-meter gains in 6-minute walking distance versus placebo. Pencina 2023 (J Gerontol A Biol Sci Med Sci) ran a 28-day dose-response trial showing blood NAD+ rose linearly with NMN dose from 100 mg to 900 mg, with 500-600 mg as the inflection point. Why we ship 500 mg, not 250 mg: 500 mg is the upper end of the trial range with more headroom for users who weigh more than the trial cohorts (Japanese trial participants averaged ~60 kg) and who don't have the homogeneous methylation profiles of the trial populations. Vegan capsule, β-NMN ≥99% by HPLC, third-party 17025-tested per batch.

NMN 1000 mg Double Strength — the high-dose arm

1000 mg/day is the dose that Yi 2022 (GeroScience) used as the high-dose arm in 80 healthy adults aged 40-65 over 60 days; the 1000 mg arm showed greater blood NAD+ elevation, higher 6-minute walking distance, and biological-age regression by HOMA-derived markers compared to the 300 mg arm. Pencina 2023's dose-response showed continued NAD+ elevation up to 900 mg/day with no plateau. Who this strength is for: the 50+ cohort, post-menopausal women, athletes wanting endurance NAD+ support, anyone whose 12-week trial of 500 mg/day didn't move subjective endpoints (energy, recovery, sleep), and biohackers tracking whole-blood NAD+ panels who want to push into the upper trial range. Higher doses make the methylation cofactor more important — most 1000 mg/day users add TMG 1000 mg. β-isomer ≥99% by HPLC, third-party 17025-tested per batch.

Longevity Stack Bundle — NMN + Resveratrol

The canonical Sinclair stack. NMN provides the NAD+ substrate; trans-resveratrol activates SIRT1 directly via an allosteric site on the enzyme. Howitz 2003 (Nature) first identified resveratrol as a SIRT1 activator; Hubbard 2013 (Science) confirmed the allosteric mechanism via crystal structures and demonstrated that SIRT1 activation requires resveratrol. Timmers 2011 (Cell Metab) gave 150 mg/day resveratrol to obese men for 30 days and showed reduced sleeping metabolic rate, improved muscle mitochondrial function, and lower inflammation markers — without weight loss. Goh 2014 (Curr Biol) demonstrated that resveratrol's longevity effects in model organisms require both SIRT1 activation and an adequate NAD+ pool — meaning resveratrol alone, without NMN, runs out of substrate to deacetylate. The Longevity Stack Bundle ships both at the dose pair Sinclair himself uses (500 mg NMN morning, 1000 mg trans-resveratrol with a fat source for absorption — though 600 mg is sufficient for most users and matches Timmers 2011 × 4).

Liposomal NAD+ Ultimate 1000 mg — the comprehensive NAD+ formula

Direct oral NAD+ has historically had poor bioavailability — the molecule is too large and charged to cross the intestinal epithelium efficiently. Phospholipid encapsulation (liposomal delivery) has been demonstrated to improve oral bioavailability for charged/polar nutrients (vitamin C, glutathione, curcumin) by protecting the payload through gastric acid and presenting it to enterocytes wrapped in a phospholipid bilayer. The 10-active formula combines: NMN, direct NAD+, NR, trans-resveratrol, PQQ (Chowanadisai 2010, J Biol Chem — mitochondrial biogenesis via PGC-1α), CoQ10 (Mortensen 2014, JACC Heart Fail Q-SYMBIO trial), Quercetin (CD38 inhibitor pairing), and B-complex (NAD+ pathway cofactors — niacinamide, riboflavin, B6). For users who want the broadest possible NAD+ + mitochondrial support without managing 5 separate bottles. Phospholipid-coated softgel; refrigerate after opening to preserve liposome integrity.

NAD+ 5-in-1 Complete (Selerb) — NMN + mitochondrial + skin formula

The Selerb 5-in-1 bundles NMN + CoQ10 + B-Complex (B1, B2, B3 niacinamide, B5, B6, B7, B9, B12) + Vitamin C + Vitamin E + Hyaluronic Acid in a single capsule — designed for users whose primary use case is mitochondrial energy plus skin/connective-tissue support. The B-complex covers every NAD+-pathway cofactor: niacinamide as the salvage-cycle precursor, riboflavin (B2) as the FAD precursor that NAD+ reactions cycle against, B6 for amino-acid metabolism, B12 + folate (B9) for methylation alongside TMG. Vitamin C and Hyaluronic Acid are the collagen-synthesis cofactors that target the same Beauty & Anti-Aging endpoints (Selerb literature emphasizes the skin/connective-tissue angle). One bottle replaces 4-5: NMN + a B-complex + CoQ10 + Vitamin C + an HA. Cost-efficient for users prioritizing simplicity over independent-component dosing precision.

Three protocol tiers

Tier 1 — Entry (single-product 12-week confirmation)

Goal: confirm NMN moves your subjective endpoints before stacking anything else. Take Pure NMN 500 mg, 1 capsule on rising with water, on an empty stomach, daily for 12 weeks. Track week-by-week: morning energy 1-10, training recovery 1-10, sleep architecture (Oura/Whoop/Garmin), and one objective marker — a fasting CMP at week 0 and week 12. If by week 12 you've moved at least two of those endpoints, NMN is working in your physiology and you can step up. If nothing has moved, drop the dose and check the foundationals (sleep ≥ 7 h, magnesium, vitamin D ≥ 40 ng/mL, omega-3 index ≥ 8% — see Foundational Health) before assuming NMN failed. Total monthly cost at this tier: one bottle of Pure NMN 500 mg.

Tier 2 — Daily protocol (Sinclair-pair + cofactors)

Goal: full NMN + sirtuin-activator + methylation-buffer stack. The Longevity Stack Bundle (NMN 500 mg + Resveratrol 600 mg) is the bundle-priced base. Add TMG 1000 mg/day (replaces methyl groups burned through NNMT) and Apigenin 50 mg/day (CD38 inhibitor — slows NAD+ degradation). Take all four together in the morning with a fat source (avocado, MCT, eggs) for resveratrol/apigenin lipid-soluble absorption. This is the protocol that Sinclair himself describes publicly. What you're buying: Longevity Stack Bundle + TMG + Apigenin. Total monthly cost mid-tier; covers substrate, activator, methylation buffer, and CD38 brake — the four levers that determine how much NAD+ you make and how much you keep.

Tier 3 — Advanced (high-dose NMN + 4-pillar mitochondrial stack)

Goal: maximize NAD+ and add the mitochondrial-renewal pillars (mitophagy + biogenesis + antioxidant defense). Step up to NMN 1000 mg Double Strength as the substrate. Keep Resveratrol 600 mg (or Pterostilbene 100 mg as the more bioavailable trans-stilbene), TMG 1000 mg, and Apigenin 50 mg. Layer the four-pillar mitochondrial stack: Urolithin A 500 mg (mitophagy — Andreux 2019, Nat Metab), PQQ 20 mg (biogenesis — Chowanadisai 2010), CoQ10 400 mg (energy — Q-SYMBIO 2014), and Magnesium Glycinate 400 mg (NAD+ methylation cofactor + sleep depth). Total: NMN 1000 mg + Resveratrol/Pterostilbene + TMG + Apigenin + Urolithin A + PQQ + CoQ10 + Magnesium. The full longevity-essentialist stack. See Mitochondrial Renewal for the four-pillar deep dive and Protocols for the full schedule.

The NMN cofactor stack — TMG, Apigenin, Resveratrol, Pterostilbene, Magnesium

NMN as a standalone supplement raises NAD+ but doesn't address the four other levers that determine how much usable NAD+ you actually have at any given moment: methylation supply, CD38 degradation rate, sirtuin activation, and the magnesium that several NAD+-pathway enzymes require as a cofactor. The cofactor stack closes those gaps.

TMG (Trimethylglycine) 1000 mg — methylation buffer

Every nicotinamide molecule that NNMT methylates to MNA pulls one methyl group from SAMe. On 500 mg/day NMN this is usually invisible; on 1000 mg/day it can produce sleep changes, irritability, anxiety, or elevated homocysteine over weeks-to-months. TMG (trimethylglycine, betaine) donates methyl groups directly through betaine-homocysteine methyltransferase (BHMT), regenerating SAMe and lowering homocysteine. 1000 mg/day TMG is the standard pairing for 1000 mg/day NMN; 500 mg/day TMG suffices for 500 mg/day NMN. MTHFR-variant carriers and vegetarians (lower dietary betaine intake) often benefit from TMG even at the 500 mg NMN dose level.

Apigenin 50 mg + BioPerine — CD38 brake

CD38 is the dominant NAD+ glucohydrolase in older tissue. Inhibiting CD38 preserves more of the NAD+ you generate from each NMN dose. Apigenin (a flavonoid found in chamomile, parsley, celery) is the most-studied natural CD38 inhibitor — Escande 2013 (Diabetes) demonstrated potent CD38 inhibition with concomitant NAD+ elevation. Apigenin 50 mg + BioPerine ships at the dose Sinclair publicly describes. BioPerine (piperine extract) increases apigenin bioavailability via CYP3A4 modulation. Take alongside NMN in the morning for the daily NAD+ window.

Resveratrol 600 mg — SIRT1 allosteric activator

Resveratrol binds an allosteric site on SIRT1 and increases the enzyme's catalytic efficiency on its acetylated substrates (PGC-1α, FOXO, p53). Howitz 2003 (Nature) first identified the activation; Hubbard 2013 (Science) confirmed via crystal structures; Timmers 2011 (Cell Metab) demonstrated the metabolic effects in obese men. Trans-Resveratrol 600 mg ships the trans-isomer (the active stereochemistry — cis-resveratrol is inactive) at the lower-end Sinclair-stack dose. Take with a fat source for lipid-soluble absorption.

Pterostilbene 100 mg — the bioavailable resveratrol cousin

Pterostilbene is structurally a dimethylated trans-resveratrol — two methoxy groups replace two of resveratrol's hydroxyls. The result: 4× longer plasma half-life than trans-resveratrol (Lin 2009, J Agric Food Chem) and roughly equivalent SIRT1-activation potency. Some users prefer pterostilbene as the resveratrol replacement when they don't want to take resveratrol with a fat source every morning, or when they're prone to flushing/GI symptoms on resveratrol. 100 mg/day pterostilbene is roughly equivalent to 400-500 mg/day trans-resveratrol on SIRT1 activation, with a slightly different downstream profile (less estrogenic, more LDL-stabilizing in some cohorts).

Magnesium Glycinate 400 mg — NAD+ methylation cofactor + sleep depth

Several enzymes in the NAD+ salvage cycle require magnesium as a cofactor. Beyond that, magnesium glycinate is the most-tolerated form for sleep depth (slow-wave sleep increase) and is a co-substrate in the methylation cycle. Magnesium Glycinate 400 mg (TRAACS bisglycinate) at bedtime supports both the NAD+ pathway cofactor demand and the sleep architecture you need to actually use the NAD+ you're generating. The glycine portion is also the rate-limiting amino acid for glutathione synthesis — see Glycine 1500 mg if you're stacking GlyNAC on top.

Stacking with sister collections

Stack with NAD+ Family — direct NAD+ + NR alongside NMN

If you've been on NMN for 6+ months and want to push further, the four-routes-to-NAD+ approach (direct NAD+, NR, NMN, niacinamide) is sometimes layered on rotation: NMN morning, Liposomal NAD+ Ultimate at lunch, NR at dinner. The pharmacokinetic profiles differ enough that combination dosing maintains NAD+ longer through the day than any single precursor alone. Note: if you're cost-constrained, this is overkill — Pure NMN at the trial dose is sufficient for 90% of users.

Stack with Mitochondrial Renewal — the four pillars

NMN raises substrate. The mitochondrial-renewal stack adds the four pillars: mitophagy (Urolithin A, Spermidine), biogenesis (PQQ, NMN itself via SIRT1→PGC-1α), energy (CoQ10, Creatine, Taurine), and antioxidant defense (Alpha-Lipoic Acid, GlyNAC = Glycine + NAC, CaAKG). NMN stacked with Urolithin A + PQQ + CoQ10 is the highest-leverage four-active stack for mitochondrial output.

Stack with Cardiovascular Longevity — Omega-3 + CoQ10

NAD+ pathway works in synergy with cardiovascular substrate. Omega-3 (EPA/DHA, target Omega-3 Index ≥ 8%) lowers triglycerides and arrhythmia risk; CoQ10 is the obligate electron-transport carrier in cardiac myocytes and is depleted by statins (Marcoff 2007, JACC). Adding Omega-3 + CoQ10 alongside NMN is the protocol for anyone over 50 with cardiovascular concerns.

Stack with Metabolic — Berberine for AMPK pairing

NMN works through SIRT1; berberine works through AMPK; both converge on PGC-1α and mitochondrial biogenesis. The pairing is particularly effective for prediabetic, post-menopausal, or insulin-resistant users (the Yoshino 2021 trial population). Berberine HCl 500 mg at meals + NMN morning is the metabolic-longevity protocol.

Stack with Senolytics — Fisetin/Quercetin for SASP clearance

NMN raises NAD+; senolytics clear the senescent cells that produce SASP (senescence-associated secretory phenotype) cytokines, which themselves consume NAD+ and drive CD38 expression. The pulse paradigm — Fisetin 1.5 g × 2 days monthly + Quercetin 1.0 g × 2-3 days monthly — pairs with continuous NMN dosing without crowding. Apigenin 50 mg/day is the daily senolytic-modulator overlap with the NMN cofactor stack.

Stack with Foundational Health — Vitamin D3, Omega-3, Magnesium

If you haven't dialed in the foundationals first, NMN won't move the endpoints you care about. Vitamin D ≥ 40 ng/mL, Omega-3 Index ≥ 8%, magnesium adequate, sleep ≥ 7 h, sunlight in the morning, lift weights twice a week — those are the prerequisites that let NMN's effects show up in metabolic and energy markers.

Stack with Antioxidants — ALA, NAC, Glutathione, Astaxanthin

NAD+ is also an electron carrier. Higher NAD+ output means more electrons cycling through the mitochondria, which in older tissue with damaged complexes means more electron leak and more reactive oxygen species. Pairing NMN with redox cofactors — Alpha-Lipoic Acid 600 mg, NAC 600 mg, Glutathione 500 mg, Astaxanthin 12 mg — addresses the downstream oxidative-stress side of higher mitochondrial output.

Stack with Beauty & Anti-Aging — Collagen + HA + Biotin

NMN drives SIRT1 activity, which in skin fibroblasts upregulates collagen-I synthesis and reduces matrix metalloproteinase expression. Pairing NMN with Marine Collagen 5000 mg, HA + Vitamin C, and Biotin 10,000 mcg is the high-leverage skin/hair stack at any age.

Stack with Fertility — CoQ10 + NAD+ for IVF prep

Oocyte and sperm quality both depend on mitochondrial energy availability, which means NAD+ status and CoQ10 status both matter for fertility outcomes. NMN + CoQ10 400 mg is the published-trial-anchored couples-prep stack — see the Fertility collection for the full IVF/IUI protocol.

Week-by-week realistic timeline

Drug interactions and precautions

• Anticoagulants (warfarin, apixaban, rivaroxaban, dabigatran). Pure NMN itself has no documented anticoagulant interaction. The cofactor pair does: trans-resveratrol has weak antiplatelet activity at the 600 mg dose, and Apigenin shares some CYP3A4 effects. Coordinate INR checks with your prescriber if you're on warfarin and adding the Longevity Stack Bundle.
• Active cancer / chemotherapy. Chini 2018 (Cell Metab) flagged that some tumors upregulate NAD+ pathway expression and proliferate faster on elevated NAD+. The clinical signal is mixed and tumor-type dependent, but pause NMN dosing during active chemotherapy and discuss with oncology before resuming. Survivors in stable remission and 6+ months out from treatment can typically resume after physician approval.
• Diabetes medications (metformin, sulfonylureas, GLP-1 agonists, insulin). NMN improves insulin sensitivity (Yoshino 2021), which can compound the glucose-lowering effect of diabetes drugs. Self-monitor fasting glucose during the first 6-8 weeks; coordinate with your prescriber on whether dose adjustments are needed.
• Statins. Statins deplete CoQ10 (Marcoff 2007). NMN doesn't interact with statins directly but the recommended pairing if you're on a statin is NMN + CoQ10 200-400 mg/day — see CoQ10 and Statins.
• Pregnancy and breastfeeding. No human safety data exists for NMN in pregnancy. Pause the entire NAD+ stack throughout pregnancy and breastfeeding. Pre-pregnancy, NMN + CoQ10 is part of the published fertility-prep protocol — see Fertility.
• Transplant immunosuppressants (tacrolimus, cyclosporine, sirolimus). Apigenin and resveratrol interact with CYP3A4. Coordinate with transplant team before adding the Longevity Stack Bundle or Apigenin.
• Methylation-sensitive psychiatric medications (SSRIs, SNRIs, MAOIs). Higher NMN doses (1000 mg/day) drain methyl groups via NNMT. Pair with TMG 1000 mg/day to buffer; if you experience sleep, anxiety, or mood changes within the first 4 weeks, drop the NMN dose to 500 mg/day or pause and reassess.
• Surgery. Pause Resveratrol + Apigenin 7 days before any planned surgery. NMN itself doesn't require pausing but most clinicians prefer to pause the entire stack 7 days pre-op out of caution.
• Apigenin + grapefruit-class drugs. Apigenin's CYP3A4 effects are similar in direction to grapefruit's — drugs labeled "do not consume with grapefruit" should be discussed with your prescriber before adding Apigenin 50 mg.
• Under 18. No pediatric trials exist for NMN. Not recommended for users under 18.

Who NMN is for — and who it isn't

Who NMN is for

• Adults 35-50 noticing energy/recovery decline. The earliest cohort where NAD+ decline measurably affects daily function. Pure NMN 500 mg + foundationals is the right starting protocol.
• Post-menopausal women (Yoshino 2021's primary trial population). Insulin sensitivity, energy, sleep architecture, and bone-density-relevant SIRT1/PGC-1α pathways are all directly affected. NMN 500-1000 mg/day with TMG and Magnesium Glycinate is the trial-anchored protocol.
• Adults 50+ on cardiovascular or metabolic medications. NAD+ pathway support compounds the effects of CoQ10 + Omega-3 + Magnesium. NMN 500-1000 mg with CoQ10 + Omega-3 layered.
• Endurance athletes. Liao 2021 (JISSN) showed VO2max improvements in amateur runners on NMN 600-1200 mg/day. NMN + CoQ10 + Creatine + Taurine is the endurance stack — see Mitochondrial Renewal.
• Biohackers tracking DunedinPACE, whole-blood NAD+, or epigenetic age. Multi-year compliance with the full Tier 3 stack is the protocol that has shown sustained PACE shifts in published case series (Demidenko 2021).
• Couples in IVF/IUI prep. NMN + CoQ10 is a standard pre-cycle nutritional protocol — see the Fertility collection.

Who NMN isn't for (yet)

• Pregnancy and breastfeeding. No safety data — pause until done.
• Active chemotherapy. Pause through treatment; discuss with oncology before resuming.
• Anyone whose foundational health isn't dialed in. Sleep < 7 h, vitamin D < 30 ng/mL, omega-3 index < 4%, no exercise — fix the foundationals first. NMN won't fix poor sleep or magnesium deficiency.
• Anyone under 18. No trials.
• Anyone who can't commit to 12 weeks of daily dosing. The trial endpoints all require 8-12 weeks minimum to manifest. Three-week trials are not informative.

Quality, sourcing, and analytical standards

Every NMN SKU we ship is third-party tested at an ISO/IEC 17025-accredited contract laboratory and manufactured under cGMP per 21 CFR Part 111. The full quality framework is published at /pages/quality and the per-active sourcing detail at /pages/ingredient-sourcing. The five-test panel that runs on every NMN batch:

• HPLC identity and potency. β-NMN ≥99% by validated reverse-phase HPLC. The β-isomer is the active stereochemistry — α-NMN does not enter the mammalian salvage cycle. Cheap NMN raw material is often racemic (~50% β / 50% α). We reject lots below 99% β-isomer.
• ICP-MS heavy metals. Lead, cadmium, arsenic, mercury tested against California Proposition 65 limits per serving. Pass thresholds posted in our Quality page; NMN is a fermentation product so heavy-metal risk is low but we test to the same Cal Prop 65 threshold as our botanical SKUs.
• USP <2021> / <2022> microbial. Total aerobic count, total yeast/mold, absence of E. coli, Salmonella, S. aureus, P. aeruginosa.
• USP <467> residual solvents. NMN is produced via fermentation + enzymatic synthesis; residual solvents from extraction/purification (ethanol, methanol, ethyl acetate) tested against USP class limits.
• Stability. NMN is hygroscopic and slowly hydrolyzes to nicotinamide in moisture-exposed conditions. Bottles ship in opaque HDPE with desiccant; we recommend cool, dry storage and reject any returned product showing browning or clumping.

Per-batch CoA available on request to support@truehealthprotocol.health with the lot number printed on the bottle.

How to measure NMN/NAD+ improvement

Subjective trackers (free, do every week)

• Morning energy 1-10. First thing on waking, before caffeine. Track on a calendar; weekly average rises 0.5-1.5 points by week 8 in most users.
• Training recovery 1-10. Day-after-workout soreness. Trial-published recovery improvements correspond to 1-2 point shifts.
• Sleep architecture. Oura, Whoop, Garmin: total sleep time, deep-sleep minutes, REM minutes. NMN often increases deep-sleep duration in the first 4-8 weeks.
• RPE on a fixed cardio session. Same 30-minute Zone 2 ride or 5 km run, same time of day, same caffeine. RPE drops over weeks as mitochondrial efficiency improves.

Standard lab markers (annual or 12-week comparison)

• Fasting glucose + HbA1c + fasting insulin. Yoshino 2021 endpoint. HOMA-IR = (insulin × glucose)/405 (US units) — drops 10-25% in responders over 10-12 weeks.
• hsCRP. NMN doesn't directly target inflammation but the downstream sirtuin activity reduces NF-κB signaling. Modest shifts (~10-20%) over 6 months.
• Lipid panel + ApoB. Indirect — NMN improves metabolic flexibility which can shift triglycerides and ApoB over months. ApoB is the better marker than total cholesterol.
• CMP, CBC. Liver enzymes, kidney function, blood counts — to confirm no off-target effects.
• Homocysteine. If elevated on NMN, suggests methylation drain — add or increase TMG.

Specialized tests (optional, biohacker-tier)

• Whole-blood NAD+ panel (Jinfiniti, Nicotinamide Adenine Dinucleotide Test). Direct measurement; baseline + 8-week recheck shows whether the dose is actually moving plasma NAD+ in your physiology.
• DunedinPACE methylation pace-of-aging (TruDiagnostic). Demidenko 2021 framework. Long-term tracker — needs 6-12 month windows to show shifts.
• Omega-3 Index (OmegaQuant). Foundational — confirm you're at ≥ 8% RBC EPA+DHA before assuming NMN failed to move endpoints.
• Vitamin D 25-OH. Foundational — confirm ≥ 40 ng/mL.

Common myths and corrections

"NMN is banned by the FDA / illegal in the US."

The FDA's 2022 letter excluded NMN from being classified as a dietary supplement on the basis that it was "authorized for investigation as a new drug." The classification has been challenged in court and revised; as of this catalog's publication, NMN is being shipped as a dietary ingredient under the framework that applied prior to the 2022 letter, with further regulatory clarification ongoing. We monitor the regulatory status continuously and will update product labeling and shipping as required. For the current legal-status detail see FAQ.

"NR is better than NMN because it has more clinical trials."

NR has more pharmacokinetic-and-tolerability trials (Trammell 2016, Conze 2019, Martens 2018, Brakedal 2022 NADPARK). NMN has more functional-endpoint trials (Yoshino 2021 insulin sensitivity, Yamaguchi 2022 walking distance, Igarashi 2022 grip strength, Yi 2022 multi-endpoint, Pencina 2023 dose-response). The two precursor classes are complementary; pick on the basis of the endpoint you care about. See NMN vs NR.

"NMN converts to nicotinamide in the gut so oral NMN doesn't work."

Some NMN does hydrolyze to nicotinamide before absorption; the rest is absorbed via the SLC12A8 transporter (Grozio 2019, Nat Metab) directly into enterocytes and converted by NMNAT to NAD+ in the portal blood. Both Yoshino 2021 (muscle insulin signaling), Yamaguchi 2022 (walking distance), and Pencina 2023 (dose-linear blood NAD+) demonstrate that oral NMN produces NAD+-pathway effects in tissues beyond the gut. The gut-conversion concern is partial but doesn't invalidate oral NMN.

"You need IV NAD+; oral supplementation doesn't work."

IV NAD+ produces a transient peak that lasts hours. Oral NMN at trial doses raises whole-blood NAD+ 1.5-2× over baseline within 2-4 weeks and maintains the elevation as long as you keep dosing (Yoshino 2021, Pencina 2023). For the population goal of long-term NAD+ replenishment, daily oral NMN is the model the published trials use.

"Resveratrol doesn't work because pterostilbene is more bioavailable."

Both work. Resveratrol has more SIRT1-activation evidence in published trials (Howitz 2003, Hubbard 2013, Timmers 2011); pterostilbene has better pharmacokinetics (Lin 2009) and may produce equivalent SIRT1 effects at lower doses. The Longevity Stack ships trans-resveratrol because that's the molecule the trials used; users who prefer pterostilbene can substitute Pterostilbene 100 mg.

Cost tiers and what each one buys you

• $30-50/month — Tier 1 entry. Pure NMN 500 mg as a single bottle. The minimum to confirm NMN moves your endpoints over 12 weeks before stacking anything else.
• $60-100/month — Tier 2 daily protocol. Longevity Stack Bundle (NMN 500 + Resveratrol 600) at bundle pricing, plus TMG and Apigenin layered. The full Sinclair-pair plus methylation buffer plus CD38 brake.
• $120-200/month — Tier 3 advanced. NMN 1000 + Resveratrol or Pterostilbene + TMG + Apigenin + Urolithin A + PQQ + CoQ10 + Magnesium. The full longevity-essentialist stack with mitochondrial-renewal pillars layered.
• $200-300/month — comprehensive. Add Liposomal NAD+ Ultimate (covers direct NAD+ + NR alongside NMN) for users who want the broadest possible NAD+ pathway coverage. Optional unless you've been on Tier 3 for 6+ months and want to push further.

FAQ

How do I pick between Pure NMN 500 mg and NMN 1000 mg Double Strength?

Default to 500 mg unless you're 50+, post-menopausal, or known to be a slow responder. The 500 mg dose matches the largest published trial cohorts and is sufficient for most users to see endpoints by week 8-12. Step up to 1000 mg if 12 weeks of 500 mg didn't shift any subjective or objective marker, or if you're starting from the Yi 2022 high-dose-arm population profile (40-65, healthy adults wanting maximum NAD+ elevation).

When should I take NMN — morning or evening?

Morning, on an empty stomach, ideally within 30 minutes of waking. NAD+ has a circadian rhythm (peaks early in the active phase), and matching exogenous NMN to your endogenous peak amplifies the signal. Evening dosing is associated with sleep disruption in some users — likely via SIRT1's effects on circadian gene expression. See Best Time to Take NMN.

Empty stomach or with food?

NMN absorption is relatively unaffected by food but the stack matters. Resveratrol and Apigenin both need a fat source for absorption — so the practical answer is: NMN on rising, then 30 minutes later eat breakfast with your fat source and take Resveratrol + Apigenin + TMG with food. Some users take everything together with a tablespoon of MCT or olive oil — that works too.

Do I need TMG?

Yes, on 1000 mg/day NMN. Optional but recommended on 500 mg/day. Required if you have a known MTHFR variant, are vegetarian, or notice methylation-sensitive symptoms (anxiety, irritability, sleep changes, elevated homocysteine on labs).

Do I need Apigenin?

Strongly recommended. Apigenin's CD38-inhibition compounds NMN's NAD+-elevation effect — you keep more of the NAD+ you generate. The Sinclair stack includes Apigenin 50 mg/day for this reason.

Can I open the capsule and put NMN in a smoothie?

Don't. NMN is hygroscopic and degrades on contact with moisture and light. The opaque capsule is part of the stability framework. Take with water; let the capsule do the protective job until it dissolves in your stomach.

How long until I see anything?

Subjective energy: weeks 2-4. Recovery: weeks 3-5. Sleep architecture: weeks 4-8. Functional endpoints (walking distance, grip strength, insulin sensitivity): weeks 8-12. Methylation-age slope (DunedinPACE): 6-12 months. See the timeline.

Should I cycle NMN — take breaks?

No clinical evidence supports cycling. Trial cohorts dosed continuously for 8-26 weeks without rest periods. Some biohackers cycle 5-on / 2-off because of the methylation drain question, but TMG addresses that more directly than cycling does. If you want to take a break for cost reasons, that's fine — NAD+ falls back to baseline within 1-2 weeks of stopping.

Is the bundle (Longevity Stack) cheaper than buying NMN and Resveratrol separately?

Yes. The Longevity Stack Bundle ships at bundle pricing — typically 15-20% lower per-component than separate purchases.

Is NMN vegan?

Yes. The β-NMN raw material is produced via fermentation; our capsule is vegan (HPMC, plant-derived). All five SKUs in the collection are vegan-suitable except where bundled with non-vegan additions (the Selerb 5-in-1 should be confirmed via the bottle label for users with strict vegan requirements; product pages have the per-SKU detail).

Is NMN safe long-term?

The longest published continuous-dosing human trial is 26 weeks (Pencina 2023) and showed no safety signals. Animal data span much longer durations. The realistic answer: human safety beyond 6 months is inferred from animal data and the substantial overlap between dietary nicotinamide intake and endogenous NMN cycling, but not directly proven by RCT. Most experts treat NMN as low-risk for indefinite dosing in healthy adults.

Does NMN cause hot flashes / make hot flashes worse?

No published association. Some users report transient flushing in the first 1-2 weeks (likely related to nicotinamide-pathway flux), which usually resolves. Pure NMN does not cause the niacin-class flushing that nicotinic acid causes — that's a different molecule.

Returns and guarantee?

30-day satisfaction guarantee on every NMN SKU — see /pages/guarantee for the full terms. If a 12-week trial doesn't move your endpoints we'll refund the unopened portion of follow-on bottles.
