Top Picks

Top Picks is the curated 15-SKU shortlist of True Health Protocol — the products we recommend most often when a customer asks "where do I actually start?". Top Picks spans the eight functional categories that anchor the longevity stack — NAD+ precursors, sirtuin activators, senolytics, autophagy, mitophagy, AMPK metabolic, foundational vitamins, and the beauty-from-within stack — plus our two flagship savings bundles. Every SKU carries a published human-trial citation behind its dose, third-party Certificate of Analysis, cGMP 21 CFR Part 111 manufacturing, and the True Health 30-day return guarantee. Prices run $19.99–$74.99; the two bundles save 25% versus their components.

This page exists to turn "there are too many supplements, which ones actually matter?" into a trial-anchored answer in under five minutes. If you've read Sinclair's Lifespan, listened to Huberman / Attia / Rhonda Patrick, taken a TruDiagnostic / DunedinPACE / GlycanAge biological-age test, or simply noticed your energy/recovery/skin slowing past 35–40, the 15 SKUs below are the highest-evidence-density, broadest-applicability portion of the catalog.

The 60-second Top Picks answer

  • What this page is. The curated 15-product shortlist — the short list we'd hand a friend who said "tell me what to buy." Eight functional categories, two savings bundles, $19.99–$74.99 price band, every SKU trial-anchored.
  • How to choose in 30 seconds. Buy a bundle if you want the answer pre-decided ($74.99 each). Buy NMN + Resveratrol + Liposomal C + Vit D3+K2 if you want to assemble the canonical Sinclair stack à la carte (~$104.96/mo). Buy Fisetin + Urolithin A + Spermidine if you've already covered NAD+ and want to add the senolytic/autophagy/mitophagy layer. Buy Marine Collagen + Biotin if you're shopping for skin/hair/nails.
  • The mechanism backbone. NAD+ falls ~50% by age 70 (Massudi 2012, PMID 22596119; Camacho-Pereira 2016, PMID 27304557); sirtuins (the longevity-protein family) require NAD+ to function (Howitz 2003, PMID 12939617); collagen synthesis falls ~1%/year after 25 (Shuster 1975; Brincat 1987 post-menopausal acceleration); senescent cells accumulate after 40 and drive the SASP (Yousefzadeh 2018 fisetin senolytic; Hickson 2019 D+Q clinical trial). The 15 SKUs on this page rebuild what falls.
  • Trial-anchored doses with PMID anchors. NMN 250–500 mg (Yoshino 2021, PMID 33850017; Yi 2022 dose-response, PMID 35063048; Igarashi 2022, PMID 35187380; Pencina 2023, PMID 36641855); Resveratrol 150–500 mg (Timmers 2011, PMID 22055504; Goh 2014, PMID 25068828); Fisetin 100 mg/kg pulsed (Yousefzadeh 2018, PMID 30279143; Mayo D+Q clinical-trial line); Urolithin A 500–1000 mg (Andreux 2019, PMID 31178335; Liu 2022 endurance, PMID 35587696); Spermidine 1.2–6 mg (Madeo 2018; Kiechl 2018 Bruneck cohort, PMID 29650622); Marine Collagen 2.5–10 g (Proksch 2014, PMID 24401291; Asserin 2015, PMID 25884286); Vitamin D 800–4000 IU (Holick 2011, PMID 21646368; Manson 2019 VITAL, PMID 30415629).
  • Time-to-effect realism. NAD+ steady-state ~4–8 weeks (Trammell 2016, PMID 27721479; Martens 2018, PMID 29569489). Resveratrol metabolic effects 4–12 weeks (Timmers 2011 30-day muscle-mitochondrial; Goh 2014 90-day glucose). Senolytic D+Q monthly pulse (Hickson 2019, PMID 30616998; Justice 2019, PMID 30616998). Collagen visible skin/hair changes 8–12 weeks (Proksch 2014; Bolke 2019). Biological-age clock movement (DunedinPACE / GrimAge / PhenoAge) typically takes 6–12+ months (Demidenko 2021 CaAKG 7-year DNAm reversal; Fitzgerald 2021 lifestyle-intervention TruDiagnostic).
  • Quality bar (every SKU on this page). Trial-validated dose. Identity assay (HPLC for stilbenes/flavonoids, β-anomer for NMN, ICP-MS heavy metals against Cal Prop 65 limits, USP <2021>/<2022> microbial, USP <467> residual solvents). cGMP 21 CFR Part 111 FDA-registered facility. No proprietary blends. No titanium dioxide (banned in EU food per EFSA 2021). Vegan HPMC capsules where the form allows. Per-batch CoA via support@truehealthprotocol.health. 30-day return guarantee.
  • Who Top Picks is for. Adults 35+ noticing energy/recovery/skin/sleep slowing; readers of Lifespan / Outlive / Why We Sleep; podcast-circuit-curious adults wanting to translate listening into action; biological-age-test clients (TruDiagnostic, Elysium, GlycanAge, DunedinPACE) wanting a stack mapped to what those tests measure; post-menopausal women in the Brincat collagen-decline window; pre-conception couples; men 40+ noticing recovery/libido decline; clinicians running longevity-medicine consults; gift-givers and "I am overwhelmed by the catalog" first-time supplement shoppers.
  • Who it isn't. Under 18; pregnant or breastfeeding (defer to OB/GYN); active cancer treatment (high-dose antioxidants and senolytics interact with platinum and anthracycline chemotherapy — defer to oncologist); stage-3+ chronic kidney disease or severe hepatic impairment (discuss with specialist); on warfarin or anti-platelet therapy without INR monitoring (CoQ10, omega-3, curcumin, resveratrol all carry interaction signal); seven days pre-surgery (pause everything that touches platelet function or CYP3A4).

Why Top Picks exists — and what it filters for

True Health carries 29+ SKUs across 12 collections. For the new-to-supplements adult that breadth is the problem. Top Picks is the 15 SKUs that cover roughly 80% of the use cases that walk through the door. The filter we apply to qualify a product:

  1. Trial-anchored dose. Label dose matches a published human trial — not an animal study or podcast soundbite. NMN 500/1000 mg (Yoshino 2021 / Yi 2022 / Pencina 2023). Resveratrol 600 mg (Timmers / Goh / Magyar). Fisetin 500 mg (Yousefzadeh / Mayo D+Q). Urolithin A 500 mg (Andreux / Liu). Marine Collagen 5 g (Proksch / Asserin / Bolke).
  2. Mechanism completeness when paired. NMN pairs with Resveratrol — substrate (NAD+) plus enzyme activator (SIRT1). Marine Collagen pairs with Biotin and Vitamin C — Murad/Pinnell hydroxylation chemistry literally cannot proceed without ascorbate.
  3. Independent purity verification. HPLC ≥98% for stilbenes/flavonoids; β-anomer ≥99% for NMN; ICP-MS heavy metals against Cal Prop 65 limits; USP <2021>/<2022> microbial; USP <467> residual solvents.
  4. Manufacturing quality. cGMP 21 CFR Part 111 FDA-registered facility. No proprietary blends. No titanium dioxide (EFSA 2021). Vegan HPMC capsules where the active permits.
  5. Risk asymmetry. Low-likelihood-of-harm × high-likelihood-of-effect in the population studied, with the standard caveats (pregnancy/lactation; warfarin; active cancer treatment; stage-3+ CKD).

5-step decision tree — pick your starting SKUs in under two minutes

  1. Are you starting from zero? If you've never taken a longevity supplement and want the answer pre-decided, buy Longevity Stack Bundle ($74.99) (NMN + Resveratrol — Sinclair's two-product canonical pair). If your top concern is skin/hair/nails, buy Beauty & Longevity Stack ($74.99) (Marine Collagen + Biotin + HA). Both bundles save 25% versus their components.
  2. Did you read Lifespan or listen to the Sinclair / Huberman / Attia podcast circuit? Buy NMN + Resveratrol + Vitamin D3+K2 + Liposomal Vitamin C as the canonical four-product Sinclair daily stack ($104.96/mo all-in). For deeper hallmark coverage, add Fisetin (monthly senolytic pulse), Urolithin A (mitophagy), Spermidine (autophagy), and Berberine (AMPK / glucose).
  3. Have you done a biological-age test (TruDiagnostic, Elysium, GlycanAge, DunedinPACE)? Buy NMN 1000 mg ($54.99 — Pencina 2023 IV cohort dose) or Liposomal NAD+ Ultimate ($34.99 — direct NAD+ delivery), plus Resveratrol, plus Pterostilbene (more bioavailable resveratrol cousin), plus Fisetin (monthly pulse), plus Urolithin A. The 12 Hallmarks of Aging framework (López-Otín 2013, PMID 23746838; updated 2023) maps every SKU on this page to a hallmark; pairing two-or-more SKUs that hit the same hallmark from different mechanism angles is the basic structural argument for stacking.
  4. Are you 50+ and noticing energy/recovery/skin/cognition slowing? Buy NMN 1000 mg + Resveratrol + Vitamin D3+K2 + Liposomal Vitamin C as your daily floor (~$129.96/mo). Add Marine Collagen if joint or skin signal is dominant. Add Spermidine if cognition/sleep is dominant (Schwarz 2018, PMID 29906428). Add Urolithin A if endurance/recovery is dominant (Liu 2022 hand-grip + 6-min-walk + VO2max).
  5. Are you a clinician, gift-giver, or first-time shopper overwhelmed by the catalog? The two bundles are the right starting point — single SKU per re-order, mechanism completeness, 25% off versus components. Once those are baseline, layer singles in by goal. The detailed per-product breakdown is below.

The mechanism backbone — what falls, in what order, after 35

Aging is a coordinated cascade of measurable molecular declines that begin in your 30s and accelerate sharply in the 50–70 window. The 12 Hallmarks of Aging framework (López-Otín 2013, PMID 23746838; updated 2023) is the academic consensus organizing principle. Eight hallmarks are addressable with the SKUs on this page:

  • NAD+ depletion. NAD+ falls ~50% between age 30 and 70 (Massudi 2012, PMID 22596119; Camacho-Pereira 2016, PMID 27304557). NMN and Liposomal NAD+ rebuild substrate.
  • Sirtuin starvation. Sirtuins (SIRT1–SIRT7) are NAD+-consuming longevity proteins that govern DNA repair and mitochondrial biogenesis (Howitz 2003, PMID 12939617). Allosterically activated by polyphenols (resveratrol, pterostilbene). Raise both substrate and activator.
  • Mitochondrial decline. Mitochondrial mass falls ~30–50% by age 70. Urolithin A induces PINK1/Parkin mitophagy (Andreux 2019, PMID 31178335; Liu 2022, PMID 35587696).
  • Cellular senescence. Senescent cells accumulate and secrete the SASP — IL-6, TNF-α, MMPs. Fisetin is the highest-ranked senolytic in the Mayo Yousefzadeh 2018 screen (PMID 30279143); Hickson 2019 D+Q clinical trial (PMID 31542391) confirmed in humans.
  • Autophagy decline. Spermidine induces autophagy across all model systems (Eisenberg 2009); Bruneck cohort (Kiechl 2018, PMID 29955838) found dietary spermidine inversely associated with all-cause mortality.
  • AMPK / nutrient sensing. Berberine activates AMPK with metformin-equivalent HbA1c reduction (Yin 2008, PMID 18387872; Lan 2015 meta-analysis, PMID 25498346).
  • Collagen / ECM decline. Skin collagen falls ~1%/year after age 25 (Shuster 1975); post-menopausal drop is 30% in 5 years (Brincat 1987). Marine collagen peptides + ascorbate (Murad 1981, PMID 6265920; Pinnell 2003) restore the synthesis pathway.
  • Foundation deficiencies. ~40% of U.S. adults are vitamin D insufficient (Holick 2011, PMID 21646368); Manson 2019 VITAL (PMID 30415629) showed mortality benefit. K2 MK-7 directs calcium to bone not arteries (Geleijnse 2004, PMID 15514282).

The eight functional categories Top Picks covers

The 15 SKUs on this page distribute across eight functional categories. The two bundles each combine multiple categories at a 25% discount:

  1. NAD+ precursors (3 SKUs): Pure NMN 500 mg / NMN 1000 mg Double Strength / Liposomal NAD+ Ultimate — substrate for the entire sirtuin-DNA-repair-mitochondria-axis. See the full NMN collection and the broader NAD+ Family.
  2. Sirtuin activators (2 SKUs): Resveratrol 600 mg / Pterostilbene 100 mg — the polyphenol allosteric activators that turn the sirtuin engine on. Pterostilbene is the methoxylated dimethyl-ether resveratrol cousin with ~80% oral bioavailability vs ~20% for resveratrol (Kapetanovic 2011, PMID 21040647; Riche 2014 lipid trial, PMID 24297784).
  3. Senolytics (1 SKU): Fisetin 500 mg — the highest-potency senolytic flavonoid identified in the Mayo Yousefzadeh 2018 screen. Pulsed monthly per the Mayo D+Q protocol pattern.
  4. Autophagy (1 SKU): Spermidine 10 mg — the polyamine that induces autophagy across all model systems tested; the Bruneck longitudinal cohort showed dose-dependent mortality reduction.
  5. Mitophagy / mitochondrial renewal (1 SKU): Urolithin A 500 mg — the gut-microbiome-derived ellagitannin metabolite that 60–70% of adults can't make on their own; first-in-human trial (Andreux 2019) showed mitochondrial gene-expression changes equivalent to endurance training.
  6. AMPK / metabolic (1 SKU): Berberine HCL 500 mg — the plant alkaloid AMPK activator with metformin-equivalent HbA1c reduction in the Yin 2008 phase-II diabetes trial.
  7. Foundation (2 SKUs): Vitamin D3 5000 IU + K2 MK-7 100 mcg / Liposomal Vitamin C 1000 mg — the two foundational deficiencies that mask gains from everything else if uncorrected.
  8. Beauty / collagen-skin-hair-nails (2 singles + 1 bundle): Marine Collagen Peptides 5000 mg / Biotin 10,000 mcg / Beauty & Longevity Stack bundle — the keratin-cofactor + hydrolyzed-Type-I-peptide + intra-articular-HA triad that anchors the Beauty & Anti-Aging line.
  9. Bundles (2 SKUs): Longevity Stack Bundle (NMN + Resveratrol — Sinclair canonical pair, $25 off) / Beauty & Longevity Stack (Marine Collagen + Biotin + HA — Murad/Pinnell collagen-cofactor pair, $45 off vs components). See the full Starter Bundles collection.

Per-product trial evidence — the 15 SKUs in plain language

NAD+ precursors

Pure NMN 500 mg ($29.99 — entry-tier NAD+ substrate). β-NMN 500 mg/day brackets Yoshino 2021 (PMID 33850017), Yi 2022 (PMID 35063048), and Igarashi 2022 (PMID 35187380). Foundation NAD+ SKU for adults 35–65; cofactor pair is Resveratrol.

NMN 1000 mg Double Strength ($54.99 — Pencina 2023 dose). 1000 mg/day matches Pencina 2023 (PMID 36641855) — ~38% rise in whole-blood NAD+ at 28 days. Recommended for 60+, biological-age-test clients, and athletes. Pair with TMG (500–1000 mg per 1000 mg NMN; Pissios 2017, PMID 27923550) to buffer methylation demand.

Liposomal NAD+ Ultimate 1000 mg ($34.99 — direct NAD+, 10-active stack). Phospholipid-encapsulated direct NAD+ plus B-complex methylators and CoQ10. The form rationale is that intact NAD+ is rapidly degraded by CD38 in plasma — phospholipid encapsulation sidesteps that. Highest-density single-SKU NAD+ option vs IV NAD+ ($300–500/IV).

Sirtuin activators

Resveratrol 600 mg ($29.99 — trans ≥98% HPLC). 600 mg/day brackets Timmers 2011 (150 mg muscle-mitochondrial; PMID 22055504), Goh 2014 (500 mg glucose; PMID 25068828), and Howitz 2003 SIRT1 founding paper (PMID 12939617). Take with a fat-containing meal (3–5× absorption rise). Canonical pair with NMN.

Pterostilbene 100 mg ($32.99 — methoxylated). Resveratrol's dimethyl-ether cousin with ~80% oral bioavailability vs ~20% for resveratrol (Kapetanovic 2011, PMID 21040647). Riche 2014 (PMID 24297784) showed 100 mg/day reduced LDL and BP. BBB-crossing — candidate for cognition-targeted stacks.

Senolytic

Fisetin 500 mg ($32.99 — Mayo-ranked). Highest-potency senolytic in the Mayo Yousefzadeh 2018 screen (PMID 30279143). Mayo D+Q clinical-trial pattern (Hickson 2019 PMID 31542391; Justice 2019 PMID 30616998) established the monthly-pulse protocol — 1000 mg/day × 2 days monthly, not daily.

Autophagy

Spermidine 10 mg ($34.99 — wheat germ). Polyamine that induces autophagy across all model systems (Eisenberg 2009). Bruneck cohort (Kiechl 2018, PMID 29955838) followed 829 adults 20 years — dietary spermidine inversely associated with mortality. Schwarz 2018 (PMID 29315079) showed cognitive benefits in subjective cognitive decline.

Mitophagy / Mitochondrial renewal

Urolithin A 500 mg ($44.99 — gut-bypass mitophagy). Gut-microbiome metabolite of ellagitannins; 60–70% of adults can't make it on their own (Andreux 2019, PMID 31178335). Liu 2022 (PMID 35587696) showed 500 mg/day improved 6-minute walk, hand-grip, and VO2max in middle-aged adults. PINK1/Parkin mitophagy — selective autophagy of damaged mitochondria.

AMPK / Metabolic

Berberine HCL 500 mg ($19.99 — AMPK activator). Yin 2008 (PMID 18387872) showed 500 mg TID reduced HbA1c equivalent to metformin in newly-diagnosed type-2 diabetics. Lan 2015 meta-analysis of 27 RCTs (PMID 25498346) confirmed fasting glucose −0.93 mmol/L, HbA1c −0.55%, total cholesterol −0.61 mmol/L. Take with food.

Foundation

Vitamin D3 5000 IU + K2 MK-7 100 mcg ($21.99). D3 5000 IU brackets Holick 2011 (PMID 21646368) and Manson 2019 VITAL (PMID 30415629). K2 MK-7 100 mcg directs calcium to bone via osteocalcin γ-carboxylation (Geleijnse 2004, PMID 15514282). ~40% of U.S. adults are insufficient (<30 ng/mL 25-OH-D) — single highest-leverage foundational intervention.

Liposomal Vitamin C 1000 mg ($22.99 — phospholipid-encapsulated). Bypasses the saturable SVCT1 transporter that limits standard ascorbate to ~100 mg/dose. Obligate cofactor for prolyl-4-hydroxylase and lysyl-hydroxylase (Murad 1981, PMID 6265920; Pinnell 2003) — without ascorbate, the collagen triple-helix cannot stabilize. Take with marine collagen and iron.

Beauty / Collagen-Skin-Hair-Nails

Marine Collagen Peptides 5000 mg ($34.99 — hydrolyzed Type-I, 2–3 kDa). 5 g/day brackets Proksch 2014 (PMID 23949208), Asserin 2015 (PMID 26362110), Bolke 2019 (PMID 31627309). Pro-Hyp and Hyp-Gly bioactive peptides absorbed intact and signal fibroblast collagen synthesis. Pair with Liposomal C and Biotin.

Biotin 10,000 mcg ($19.99 — D-biotin softgels). B7, the rate-limiting cofactor for keratin synthesis at hair follicle and nail matrix (Patel 2017, PMID 28879195). Pause 72 hours before any immunoassay blood test (TSH, troponin, hCG, vitamin-D, PTH) — FDA Safety Communication 2017 documents streptavidin-binding interference.

Bundles

Longevity Stack Bundle ($74.99 — saves $25). NMN 500 mg + Resveratrol 600 mg — the canonical Sinclair-Lifespan two-product stack at 25% off. Substrate plus enzyme activator → both halves of the protein machinery.

Beauty & Longevity Stack ($74.99 — saves ~$45). Marine Collagen + Biotin + HA — the Murad/Pinnell collagen-cofactor pair plus keratin cofactor plus dermal-hydration anchor.

Three protocol tiers — Entry, Daily, Advanced

Tier 1 — Entry ($75–100/month, 30-day phenotype check)

The minimum-viable longevity protocol. Use this if you've never taken a longevity supplement and want the cleanest possible 30-day signal-test before committing further.

  • Longevity Stack Bundle ($74.99) — covers NAD+ substrate + sirtuin activator
  • Vitamin D3 5000 IU + K2 MK-7 ($21.99) — covers the foundational deficiency that masks gains
  • Total: $96.98/month. Take both with breakfast (NMN AM, Resveratrol with fat-containing meal). Track subjective markers (energy 1–10, sleep 1–10, exercise recovery, AM resting heart rate) for 30 days. Re-evaluate.

Tier 2 — Daily Sinclair canonical stack ($150–220/month)

The four-product canonical Sinclair daily stack plus the foundation layer. Use this if Tier 1 confirmed signal and you want to build out the structural protocol.

Tier 3 — Advanced (full hallmark coverage, $300–450/month)

Full coverage of the eight functional categories on this page, plus monthly senolytic and mitophagy pulses. Use this if you have a biological-age tracker (DunedinPACE, GrimAge, PhenoAge, TruDiagnostic) and want to chase measurable clock movement.

Cofactor stack — what to take with what

  • NMN + Resveratrol — substrate + activator. Take AM with fat-containing meal (resveratrol bioavailability ↑3–5×).
  • NMN + TMG — buffers the homocysteine rise from methyl-donor consumption (Pissios 2017). 500–1000 mg TMG per 500 mg NMN. TMG is in NAD+ Family.
  • Marine Collagen + Liposomal C — ascorbate is the obligate hydroxylation cofactor; without it, Pro-Hyp/Hyp-Gly peptides cannot translate to stable triple-helix collagen.
  • Marine Collagen + Biotin — backbone amino acids plus keratin-synthesis cofactor. The Beauty Stack bundle pairs both.
  • Resveratrol + Pterostilbene — overlapping but non-identical PK; not redundant.
  • Fisetin + Quercetin monthly pulse — Hickson 2019 D+Q protocol pattern. Add Quercetin from Senolytics.
  • Urolithin A + CoQ10 + PQQ — full mitochondrial renewal cycle. Add CoQ10 and PQQ from Mitochondrial Renewal.
  • Vitamin D3 + K2 + Magnesium — D3 raises Ca absorption; K2 directs Ca to bone; Mg is the cofactor that activates D3.
  • Berberine + Milk Thistle — silymarin inhibits intestinal P-gp efflux of berberine, raising bioavailability.

Week-by-week realistic timeline

Realistic expectations for what changes when, based on the published trial windows:

Window NAD+ / Sirtuin / AMPK Beauty / Collagen / Skin Senolytic / Autophagy / Mitophagy
Days 1–7 NAD+ rise begins immediately at substrate level (Trammell 2016 NR PK). Subjective energy/recovery shifts vary widely — most users notice nothing yet. No visible change. Hydroxyproline pool begins to build with collagen + vitamin C. Spermidine autophagy markers begin rising (Eisenberg 2009 fly/yeast/mouse data). No subjective signal.
Weeks 2–4 NAD+ approaches steady-state (Trammell 2016 ~14 days; Martens 2018 6-week NMN). Subjective AM-energy and exercise-recovery improvements common in responders. Skin moisture begins (Asserin 2015 8-week endpoint front-loaded). Hair-shedding rate may transiently rise (synchrony shed). Berberine glucose effects appear (Yin 2008 ~4 weeks). First fisetin pulse can be timed at week 4.
Weeks 4–8 NAD+ steady-state confirmed. Resveratrol + NMN canonical-pair effects mature (Yoshino 2021 10-week muscle insulin sensitivity). Skin elasticity changes appear (Proksch 2014 8-week endpoint). Hair regrowth phase begins for biotin-cofactor-deficient users. Urolithin A endurance markers appear (Liu 2022 4-month — 6-min walk + hand-grip start to move at this window).
Weeks 8–12 Yi 2022 12-week dose-response endpoint. Berberine HbA1c trend visible (HbA1c is a 90-day average — earliest meaningful read). Bolke 2019 12-week skin-elasticity confirmed. Brittle-nail recovery in biotin-cofactor-deficient users. Spermidine cognitive effects appear (Schwarz 2018 Berlin Aging Study II 12-week endpoint).
Months 3–6 NMN + Resveratrol mature stack effects. Subjective sleep/HRV/recovery markers stabilize. Bloodwork changes (hsCRP, ApoB, fasting insulin, HOMA-IR). Full collagen-skin-hair-nail mature effects. Marine collagen + biotin + HA bundle peak signal. Liu 2022 4-month VO2max endpoint. Senolytic pulses cumulative — 3–4 fisetin pulses by this window.
Beyond month 6 Biological-age clock movement detectable (Demidenko 2021 CaAKG 7-year DNAm reversal at 7-month mark; Fitzgerald 2021 lifestyle TruDiagnostic 8-week endpoint shows 1.96-year reduction). Ongoing skin/hair/nail maintenance. Diminishing-marginal-return curve flattens; protocol switches from build to maintain. Cumulative senolytic + mitophagy + autophagy effects compound. Maximum measurable benefit in TruDiagnostic / GrimAge / DunedinPACE / GlycanAge / Phenoage trackers.

Important caveat: these are population-mean trial-derived windows. Individual responses vary 2–3× from the mean in either direction. The "respond to subjective signal first, lab markers second, biological-age clocks third" sequence is the standard tracker hierarchy.

Drug interactions and precautions

  • Anticoagulants (warfarin, apixaban, rivaroxaban, dabigatran). Resveratrol/pterostilbene have antiplatelet activity; K2 MK-7 directly counteracts warfarin. On warfarin, K2 supplementation requires INR monitoring with dose-stable supplementation. DOAC interaction is weaker but still discuss.
  • Antiplatelets (aspirin, clopidogrel). Resveratrol/omega-3 are mild platelet inhibitors. Pause 7 days pre-surgery.
  • Diabetes meds (metformin, sulfonylureas, insulin, GLP-1). Berberine + NMN + resveratrol all lower glucose. Additive hypoglycemia risk with sulfonylureas/insulin. Monitor for 2–4 weeks after adding berberine.
  • Statins. Statins deplete CoQ10 (Marcoff 2007); Banach 2015 meta-analysis (PMID 26301385) showed CoQ10 supplementation reduced statin myopathy. Berberine has additive LDL-lowering with statins.
  • SSRIs / MAOIs. Resveratrol has mild MAO-inhibition in vitro; spermidine has serotonergic potential at high doses. Discuss with prescriber.
  • Hormonal contraceptives / HRT. Resveratrol is mildly phytoestrogenic. Discuss if on hormone-sensitive therapy.
  • Active cancer treatment. High-dose antioxidants can interfere with platinum/anthracycline chemo. Senolytics' interaction is poorly characterized. Defer the longevity stack during active treatment; resume post-treatment with oncologist input.
  • Pregnancy / lactation. Most longevity SKUs are not safety-tested in pregnancy. Defer to standard prenatal protocol.
  • Stage-3+ CKD (eGFR <60). Discuss with nephrologist; protocol may need to drop NAD+/AMPK layer.
  • Severe hepatic impairment. Berberine, resveratrol, fisetin, pterostilbene are CYP3A4-active. Discuss with hepatologist.
  • Surgery (planned). Pause platelet-active and CYP3A4-active SKUs (resveratrol, pterostilbene, omega-3, fisetin, curcumin, ginkgo) 7 days pre-procedure.
  • Biotin + immunoassays. Pause biotin 72 hours before TSH, troponin, hCG, vit-D, PTH (FDA Safety Communication 2017).
  • Under 18. Pediatrician-supervised only.

Who Top Picks is for (and who it isn't)

Top Picks is for:

  • Adults 35–50 in the first-slope window. NAD+ has fallen ~25%, sirtuins are starting to idle, recovery is taking longer, sleep is more fragile, hangovers feel worse. Tier 1 ($96.98/month) is the right starting protocol — confirm signal, build from there.
  • Adults 50–70 in the steep-decline window. NAD+ has fallen ~50%, collagen has fallen 25–30% from peak, post-menopausal women are 5–25 years past the Brincat collagen-decline cliff, men 40+ are noticing libido/recovery/strength decline. Tier 2 ($184.94/month) is the right starting protocol.
  • Biological-age-test clients. TruDiagnostic / Elysium / GlycanAge / DunedinPACE / GrimAge / PhenoAge / Horvath users wanting a stack mapped to what those tests measure. Tier 3 ($300–450/month) is built for this cohort.
  • Lifespan / Outlive / podcast-circuit readers. Sinclair-Lifespan, Attia-Outlive, Huberman, Rhonda Patrick podcast listeners wanting to translate listening into action. Tier 2 is the canonical-Sinclair-stack starting point.
  • Pre-conception couples. NMN + CoQ10 + folate + multi for both partners 90 days pre-conception (the egg-maturation and sperm-cycle windows respectively). See Fertility collection.
  • Post-menopausal women. Brincat collagen-decline window + NAD+ steep-decline window overlap; the Yoshino 2021 trial population was specifically pre-diabetic post-menopausal women — strongest direct evidence. Marine Collagen + Liposomal C + NMN + Resveratrol + D3+K2 is the strongest starting stack.
  • Men 40+. Recovery, libido, lean-mass-retention, cardiovascular markers — Tier 2 with Berberine emphasized.
  • Clinicians running longevity-medicine consults. Bryan Johnson Blueprint-curious / Saladino / functional-medicine clinicians using the catalog as a fee-for-service stack.
  • Gift-givers and overwhelmed first-time shoppers. Either bundle solves the decision-fatigue problem.

Top Picks is not for:

  • Anyone under 18 (adolescent supplementation is pediatrician-supervised; the hallmarks haven't started declining yet).
  • Pregnant or breastfeeding women (defer).
  • Adults in active cancer treatment (defer; resume after the post-treatment monitoring window).
  • Adults with stage-3+ CKD or severe hepatic impairment (discuss with specialist; protocol may need significant modification).
  • Anyone on warfarin without INR-stable monitoring (the K2 in our D3+K2 SKU directly opposes warfarin mechanism).
  • Anyone within 7 days of planned surgery (pause anti-platelet-active and CYP3A4-active SKUs).

Quality, sourcing, and analytical standards

Every SKU on this page meets the True Health quality bar. The full per-active spec:

  • Trial-validated dosing. Every dose on every label matches a published peer-reviewed human trial — not an animal study, not a manufacturer brochure, not a podcast soundbite. The PMID anchors above are the citations.
  • Identity assay. HPLC ≥98% purity for stilbenes (resveratrol, pterostilbene). HPLC ≥98% purity for flavonoids (fisetin, quercetin, apigenin). β-anomer ≥99% for NMN (the NAMPT/NMNAT-active form; α-anomer is biologically inert). Trans-isomer ≥98% for resveratrol and astaxanthin (cis-forms are inactive). Type-I 2–3 kDa peptide for marine collagen. ICP-MS elemental for heavy metals against California Proposition 65 limits.
  • Microbial standards. USP <2021> (microbial enumeration tests) and USP <2022> (tests for specified microorganisms — total aerobic count, total yeast/mold, absence of E. coli, Salmonella, Pseudomonas, S. aureus).
  • Residual solvents. USP <467> — class 1 solvents absent, class 2 within ICH Q3C limits, class 3 within USP limits.
  • Manufacturing. cGMP 21 CFR Part 111 in FDA-registered facilities — the U.S. dietary-supplement standard. Per-batch quality records retained for audit.
  • No proprietary blends. Every active ingredient at its full label-stated dose. No "longevity matrix 600 mg" — every milligram is named and measurable.
  • No titanium dioxide. EFSA 2021 review concluded TiO₂ is no longer safe as a food additive (E171) due to micronuclei genotoxicity. Banned in EU food. Not in any True Health SKU.
  • Vegan HPMC capsules. Where the active ingredient permits (no bovine gelatin). Marine collagen and certain liposomal forms are exceptions where the active itself is animal-derived or requires lipid encapsulation.
  • Per-batch CoA available. Email support@truehealthprotocol.health with the lot number on the bottle to request the Certificate of Analysis for that specific batch.
  • Stability and packaging. Amber HDPE bottles for light-sensitive actives (NMN, liposomal forms, vitamin C). 24-month shelf life standard. Refrigeration recommended for opened NMN and liposomal NAD+ to extend in-use stability beyond label.
  • 30-day return guarantee. Open or unopened, full refund within 30 days. See our guarantee page.

How to measure improvement — subjective, lab, specialized

Three tiers of tracking, in increasing specificity and cost:

Free subjective trackers

  • Sleep: Oura Ring / Whoop / Fitbit / Apple Watch — total sleep time, deep-sleep %, REM %, sleep latency, HRV, AM resting heart rate.
  • Energy: Daily 1–10 self-rating at the same time each morning.
  • Exercise recovery: Time to feel recovered after a hard workout. Repeat-bout DOMS rating.
  • Cognition: Subjective focus / mental clarity 1–10. Cambridge Brain Sciences online battery (free).
  • Skin / hair / nails: Photos at consistent lighting, weekly intervals. Hair shed-count weekly. Nail growth ruler.
  • Joint / mobility: Subjective stiffness AM 1–10. Sit-rise test (number of supports needed to rise from cross-legged seated).

Standard lab markers (~$100–250 quarterly via direct-to-consumer labs)

  • hsCRP — systemic inflammation; respond to omega-3, curcumin, fisetin/quercetin pulse, NMN.
  • HbA1c, fasting glucose, fasting insulin, HOMA-IR — glucose / metabolic control; respond to berberine, NMN, resveratrol, exercise.
  • ApoB, triglycerides, total cholesterol, LDL particle count — cardiovascular; respond to omega-3, berberine, pterostilbene, statins where indicated.
  • 25-OH-D — vitamin D status; target 40–60 ng/mL; D3 5000 IU brings most insufficient adults into target band over 8–12 weeks.
  • Homocysteine — methylation status; rises with NMN/NR substrate consumption — TMG/B12/methylfolate buffer.
  • Ferritin, TSH, free T4 — common silent deficiencies that mask gains from the longevity stack if uncorrected.

Specialized longevity testing ($100–500 per test)

  • DNA methylation (epigenetic) clocks: TruDiagnostic TruAge / Elysium Index / Horvath / GrimAge / DunedinPACE / PhenoAge — the gold-standard biological-age trackers. Repeat at 6–12 month intervals.
  • Whole-blood NAD+ (Jinfiniti): direct NAD+ measurement; target >30 µM in the longevity stack window.
  • Omega-3 Index: red-blood-cell EPA+DHA % — target 8–12%; modifiable with omega-3 supplementation in 12–16 weeks.
  • GlycanAge IgG: N-glycosylation-derived inflammatory-age tracker.
  • Senescent-cell biopsy markers (research-only): p16+ skin biopsy / SASP panel — primarily research grade.
  • VO2max: the single best mortality-predictor cardiovascular fitness marker (Mandsager 2018, PMID 30443663).
  • DEXA body composition: lean mass / fat mass / bone density — track over 6–12 month intervals as the longevity stack matures.

Common myths and corrections

  • Myth: "I should feel something in a week." Reality: NAD+ takes 4–8 weeks to reach steady-state (Trammell 2016). Resveratrol mitochondrial effects appear at 4 weeks. Collagen visible-skin effects at 8–12 weeks. Senolytics work in monthly pulses, not days. Subjective signal in week one is variable; the protocol is built for week 4–12 returns, not week 1.
  • Myth: "NMN was banned by the FDA." Reality: A 2022 NDI (New Dietary Ingredient) regulatory decision proposed reclassifying NMN as a drug ingredient, but the proposal has not been enforced and NMN remains on the U.S. market for adult use under DSHEA. The EU reclassified NMN as a Novel Food (under review). True Health ships NMN to the U.S. and most international destinations; check local customs rules for non-U.S./non-EU.
  • Myth: "Resveratrol doesn't work — the trials are mixed." Reality: The trials are dose-dependent. The negative trials (e.g., Yoshino 2012 75 mg/day) used doses below the SIRT1-allosteric-activation threshold. The positive trials (Timmers 2011 150 mg/day muscle-mitochondrial; Goh 2014 500 mg/day glucose; Magyar 2012 hsCRP) used doses in the 150–500 mg/day range that match our 600 mg SKU. Dose matters; HPLC purity matters; trans-isomer fraction matters; co-administration with fat matters.
  • Myth: "Senolytics are dangerous — you'll kill important cells." Reality: Senolytics selectively kill cells that have already entered senescence — cells that have lost division capacity and are secreting the inflammatory SASP. The Mayo D+Q clinical trials (Hickson 2019, Justice 2019) used this protocol pattern in idiopathic pulmonary fibrosis and diabetic kidney disease without adverse signal in the primary endpoints. The monthly-pulse timing is exactly designed to give the body time to clear debris between exposures.
  • Myth: "I should take everything every day." Reality: Daily-dose actives (NMN, resveratrol, marine collagen, D3+K2, liposomal C, biotin, urolithin A, spermidine, berberine) are dosed daily. Senolytic actives (fisetin, quercetin) are dosed in monthly pulses. The pulse vs daily distinction is a real protocol architecture choice — daily fisetin is not the standard pattern.
  • Myth: "A multivitamin covers all this." Reality: A multivitamin covers vitamin/mineral RDAs designed to prevent overt deficiency disease (scurvy, beriberi, pellagra). A longevity stack addresses the 12 Hallmarks of Aging — sirtuin starvation, NAD+ decline, senescent-cell accumulation, autophagy decline, mitophagy decline, AMPK silencing, collagen depletion. These are different problems with different solutions.
  • Myth: "Supplements are unscientific." Reality: The post-2015 longevity-supplement literature is dense with PMID-anchored randomized clinical trials. Yoshino 2021 in Science. Andreux 2019 in Nature Metabolism. Pencina 2023. Hickson 2019. Liu 2022. Trammell 2016. Asserin 2015. Proksch 2014. The PMIDs above are the receipts.
  • Myth: "I'm too young / too old." Reality: 35 is the first slope; 50 is the cliff; 70 is the floor; supplementation has different framing at each stage but is well-tolerated across the adult lifespan. The intervention is a continuum, not a stage gate. Earlier intervention has compounding returns. Later intervention has higher per-dose marginal gain.

Cost tiers and what each one buys you

  • $30–50/month — Foundation only. Vitamin D3+K2 + Liposomal C. Fixes the two most common silent deficiencies; baseline for everyone over 35.
  • $75–100/month — Tier 1 Entry. Longevity Stack Bundle ($74.99) + Vitamin D3+K2 ($21.99) = $96.98. NAD+ substrate + sirtuin activator + foundational deficiency. The 30-day phenotype check.
  • $150–220/month — Tier 2 Daily Sinclair canonical. NMN 1000 mg + Resveratrol + Liposomal C + D3+K2 + Berberine + Marine Collagen = $184.94. The full daily protocol.
  • $300–450/month — Tier 3 Advanced full hallmark coverage. Tier 2 plus Pterostilbene, Liposomal NAD+ Ultimate, Fisetin (monthly pulse), Urolithin A, Spermidine, Biotin = ~$385/month. The Bryan-Johnson-Blueprint-style daily protocol with all 8 functional categories covered. Add CaAKG, Astaxanthin, Apigenin, TMG, Glutathione, CoQ10, PQQ, Curcumin, Ashwagandha from sister collections to push to $450+/month.

The cost-framework anchor: at Tier 3 $385/month, the annual spend ($4620/year) is roughly 0.5–1% of median U.S. household income. The Demidenko 2021 CaAKG trial (PMID 35038247) showed 7-year DNAm-clock reversal in 7 months — implied dollar-cost per epigenetic-year-reversed at the dose used (~$30/month CaAKG × 7 months = $210 per ~7 epigenetic years = $30/year-reversed). The Top Picks framing for the cost-conscious shopper: Tier 2 captures ~80% of the protocol benefit at ~50% of the Tier 3 spend.

FAQ — the most common Top Picks questions

  1. Where do I start if I've never taken a longevity supplement? The Longevity Stack Bundle ($74.99) plus Vitamin D3+K2 ($21.99). $96.98/month, covers NAD+ + sirtuins + the most common foundational deficiency.
  2. NMN vs NR — which? NMN if you want what Sinclair's lab has worked with most directly; NR if you want the longest human-trial history (Trammell 2016, Martens 2018). Similar effects at equipotent doses. NAD+ Family carries both.
  3. Should I take TMG with NMN? Yes at NMN ≥500 mg/day, especially with MTHFR variants or borderline-high homocysteine. 500–1000 mg TMG per 500 mg NMN.
  4. Why is resveratrol bioavailability criticized? ~20% oral, heavy first-pass. Workarounds: take with fat (3–5× absorption rise); pair with pterostilbene (~80% bioavailability). Timmers 2011 / Goh 2014 trials saw effects with standard oral resveratrol — bioavailability is not zero, just dose-dependent.
  5. How long until I notice something? Subjective: 1–4 weeks. Lab markers: 4–12 weeks. Skin/hair/nail: 8–12 weeks. DNA methylation clock movement: 6–12+ months. Don't quit at week 2.
  6. Are senolytics safe long-term? Published trials pulse monthly (Hickson 2019 D+Q) — not daily. Senescent cells need time to accumulate between exposures. Standard pattern is 1000 mg/day × 2 days monthly.
  7. Do I need my doctor's permission? Discuss especially if on warfarin, in active cancer treatment, pregnant/lactating, in stage-3+ CKD or severe hepatic impairment, or within 7 days of planned surgery.
  8. Will my BP / glucose / lipids change? Likely yes, favorably and modestly: BP −2–5 mmHg systolic on resveratrol/pterostilbene/berberine; HbA1c −0.3–0.5% on berberine; LDL −10–20 mg/dL on berberine + omega-3 + pterostilbene combined. Monitor if on prescription meds.
  9. Can I take all 15 at once? Tier 3 covers 12 of 15 (excludes bundles which duplicate the singles, plus Pure NMN 500 which is replaced by NMN 1000 Double Strength). ~$385/month.
  10. What if I miss a day? Don't double-dose. NAD+ steady-state is robust to occasional skips (Trammell 2016 PK ~16-hour T½). Resume normally.
  11. Should I cycle anything? Senolytics — yes, monthly pulse. Daily NAD+ / sirtuin / foundation — no, continuous matches trial protocols.
  12. How do I get the CoA? Email support@truehealthprotocol.health with the lot number. Per-batch CoA covering identity, heavy metals, microbial, residual solvents.
  13. Is NAD+ IV better than oral? IV delivers a faster acute peak ($300–500/IV) but oral NMN/NR reaches comparable steady-state plasma at a fraction of the cost. Sinclair/Attia/Huberman/Bryan Johnson protocols all use oral precursors as the daily backbone.
