CoQ10 400mg | Fertility & Cellular Energy Support

400 mg of pharmaceutical-grade CoQ10 per softgel — the studied therapeutic dose for mitochondrial energy production, cardiovascular muscle function, fertility (egg and sperm quality), statin-replacement support, and migraine prevention. One of the highest single-dose CoQ10 supplements in the catalog, formulated as a fat-carrier softgel because that is the absorption profile CoQ10 actually needs.

The 30-second answer

• What CoQ10 does: sits at the centre of the electron transport chain (the process that generates ATP) inside every mitochondrion. Without it, ATP production drops; with less of it, the leftover electrons leak as oxidative damage instead of becoming usable cellular fuel.
• Why supplement: endogenous CoQ10 production drops steadily after age 35 (roughly 50% by age 80, with measurable decline visible in the 30s and 40s). Statins deplete it further — they block HMG-CoA reductase, which is the same enzyme pathway your body uses to manufacture CoQ10. Several chronic conditions and a few common medications (metformin, certain beta-blockers, tricyclic antidepressants) also lower it.
• Best for: adults 40+, anyone on a statin (with their physician's awareness), couples working on fertility, athletes, recovery from illness or surgery, anyone running a longevity / mitochondrial stack, migraine-prone adults.
• Take with food (with fat). CoQ10 is fat-soluble. Bioavailability drops sharply on an empty stomach — by some pharmacokinetic studies more than 3× lower (Hidaka 2008, Lopez-Lluch 2011). Lunch or dinner with olive oil, eggs, butter, avocado, or full-fat dairy works.
• Form: ubiquinone (the standard, oxidatively stable form). Your body converts ubiquinone to ubiquinol on demand — for healthy adults under 60 the form rarely matters; what matters is dose, fat co-ingestion, and consistency.
• Trial-validated dose anchor: 300 mg/day for 2 years in the Q-SYMBIO multicenter trial (Mortensen 2014). 600 mg/day for 90 days in the Bentov fertility cohort. 100–400 mg/day for 12 weeks in migraine-prevention trials (Sándor 2005, Shoeibi 2017). 400 mg sits squarely inside the studied therapeutic range.

What CoQ10 actually does — the two roles

CoQ10 (Coenzyme Q10, also called ubiquinone) is a fat-soluble compound your body makes from the same mevalonate pathway that produces cholesterol. It concentrates in tissues with the highest sustained energy demand — heart muscle, kidneys, liver, brain, ovaries, testes — and plays two distinct roles, both inside the inner mitochondrial membrane:

• Electron transport in mitochondria. CoQ10 shuttles electrons between Complex I/II and Complex III of the electron transport chain. That chain is the final stage of converting food into ATP — the energy currency every cell uses to do work. No CoQ10, no ATP. Less CoQ10, less efficient ATP production, and more leakage of electrons that turn into reactive oxygen species (ROS) instead of fuel (Crane 2001).
• Fat-soluble antioxidant in cell membranes. CoQ10 is one of the only antioxidants that lives inside the lipid bilayer. It protects mitochondrial membranes — which is exactly where the most ROS are produced in the first place — and regenerates other antioxidants like vitamin E and glutathione (Bentinger 2010, Alleva 1995). This is the closed-loop reason CoQ10 matters more for high-mitochondrial-density tissue: it both meets the ATP demand and absorbs the resulting oxidative load.

Production declines roughly 50% by age 80, with meaningful drops visible in the 30s and 40s (Kalén 1989). Heart tissue takes the biggest hit — by age 70, cardiac CoQ10 concentrations are typically less than half of what they were at 20. That is the cleanest mechanistic explanation for why CoQ10 has been studied so heavily in cardiovascular contexts.

Where supplementation matters most

• Heart muscle. The heart has the highest sustained ATP demand of any organ. CoQ10 concentration in cardiac tissue drops significantly with age and with cardiovascular disease, and supplementation has been studied extensively for cardiovascular support — the Q-SYMBIO multicenter trial (Mortensen 2014, n=420) used 300 mg/day for 2 years and reported a significant reduction in major adverse cardiovascular events versus placebo. Talk to your physician if you are managing a cardiac condition; this is not a treatment, it is a cofactor.
• Fertility (egg and sperm). Both egg and sperm quality depend heavily on mitochondrial energy. The egg is the largest cell in the body and contains roughly 100,000 mitochondria — it has to power its own first 5–7 days of cell division before the embryo can implant and start drawing nutrients from the mother. Sperm motility runs on a flagellum that is essentially a continuously firing ATP engine. CoQ10 has been incorporated into IVF and natural-conception protocols at 200–600 mg daily for 3+ months pre-conception; the egg maturation window is roughly 90 days, so the protocol mirrors that biology (Bentov 2010, 2014; Ben-Meir 2015 mouse data; Safarinejad 2009 sperm quality).
• Statin users. If you are on a statin your CoQ10 levels are reduced as a known side effect of how the drug works. Statins inhibit HMG-CoA reductase to lower cholesterol synthesis — but that same enzyme is the early step in your body's CoQ10 manufacturing pathway, so the depletion is mechanistic, not incidental (Folkers 1990, Mortensen 1997). Supplementing back toward normal levels is one of the most common medical reasons to take CoQ10 and is openly discussed by many cardiologists. Ask your physician about appropriate dosing for your specific situation.
• Mitochondrial / longevity stack. CoQ10 supports ATP production directly. NMN, NR, and NAD+ products raise NAD+ for the upstream pathway support; PQQ promotes the creation of new mitochondria; Urolithin A clears damaged mitochondria via mitophagy; CoQ10 keeps the resulting mitochondria fed and producing energy cleanly. Each step in the cycle is necessary; CoQ10 is the one that turns the lights on.
• Migraine-prone adults. 100–400 mg CoQ10 daily has been studied for migraine frequency reduction (Sándor 2005 RCT n=42; Shoeibi 2017 n=80; Dahri 2019 meta-analysis). Results are mixed-but-positive across multiple trials. The American Academy of Neurology and Canadian Headache Society have included CoQ10 in their migraine prevention guidance, with the caveat that evidence is moderate, not strong.
• Athletes and post-exertion recovery. Sustained intense exercise depletes CoQ10 and shifts mitochondria toward higher ROS output. Endurance athletes and anyone doing >5 hours/week of intense training tend to see the largest drops (Cooke 2008; Díaz-Castro 2012).
• Periods of high mitochondrial demand. Recovery from surgery, illness, post-viral fatigue, long-COVID protocols. Your mitochondria are doing extra work; supplying the missing cofactor is reasonable (Mantle 2018 review).
• Periodontal and gum tissue. Gum tissue is one of the few peripheral tissues with surprisingly high CoQ10 demand. A small literature suggests benefit for gingival health at 60–200 mg/day; not the primary use case, but a documented one (Hanioka 1994).

Why 400 mg specifically

The studied dose range for CoQ10 is unusually wide, because different goals call for very different exposure:

• 30–100 mg: general health maintenance for younger adults with no specific concern. This is what most off-the-shelf multivitamins include, and it is roughly enough to make up for ordinary age-related decline.
• 100–200 mg: heart support, statin replacement therapy. The typical "cardiology recommendation" range when a CoQ10 supplement is being suggested as adjunct support.
• 200–600 mg: fertility protocols (both partners), athletic recovery, and mitochondrial-support side of a longevity stack. This is also the range used in most published fertility studies — typically 300–600 mg/day for 90 days pre-conception.
• Up to 1,200–3,000 mg: studied in clinical trials for specific neurological and inherited mitochondrial conditions (Parkinson's at up to 1,200 mg/day in Shults 2002; Huntington's at 600 mg/day in Huntington Study Group 2001; mitochondrial encephalomyopathies up to 3,000 mg/day under medical supervision). This is medical-supervision territory, not a self-directed dose.

400 mg in a single softgel sits squarely inside the higher therapeutic range used in fertility, athletic, and longevity-focused research. If you only need general maintenance you can use half a softgel daily (or every other day, since CoQ10 has a long tissue half-life). If you are targeting fertility or stacking it with a serious longevity protocol, 400 mg is the dose most of the literature actually points to.

Ubiquinone vs ubiquinol — the form question, answered honestly

CoQ10 exists in two interconvertible forms in your body: ubiquinone (the oxidized form, more stable in capsules) and ubiquinol (the reduced form, what your body uses to donate electrons in the antioxidant role). Most quality supplements use ubiquinone for two reasons:

• Shelf stability. Ubiquinol oxidizes back to ubiquinone in air, in light, in heat, and during shelf storage. By the time a ubiquinol softgel reaches you, a meaningful percentage has typically already converted back. Ubiquinone is shelf-stable, which is why it dominates clinical research (Bhagavan 2007).
• Conversion is built in. Healthy adults under 60 convert ubiquinone to ubiquinol on demand, in the cells that need it (Mohr 1992). The interconversion is part of normal metabolism and does not require any special pathway.
• Most large clinical trials used ubiquinone. Q-SYMBIO, Sándor migraine, the Bentov fertility cohorts, virtually the entire pre-2010 cardiovascular literature.

Ubiquinol is sometimes recommended for adults over 70, people with significant cardiovascular disease, or specific genetic differences in CoQ10 metabolism — situations where the conversion step itself may be impaired (Langsjoen 2008). For everyone else, ubiquinone at a meaningful dose with adequate dietary fat is the well-studied, lower-cost, well-evidenced choice. The bigger absorption variable, by far, is whether you take CoQ10 with fat (yes) or on an empty stomach (don't).

How long until you notice it — the realistic timeline

• Day 1–7 — plasma rises. Plasma CoQ10 reaches measurably higher levels within 4–8 hours of a fat-co-ingested dose, and steady-state plasma levels build over 5–10 days (Bhagavan 2007).
• Week 2–4 — first subjective shifts. People who were depleted (statin users, post-illness, age 60+, post-viral fatigue) often notice modestly improved exercise tolerance or reduced "just-tired-all-the-time" feeling here. This is not stimulant energy; it is more "the floor is higher."
• Week 4–8 — tissue saturation. Heart, muscle, ovary, and testis tissue reach steady-state levels. This is where any cardiovascular markers measured in studies typically begin to shift.
• Week 12 — migraine prevention endpoint. Sándor 2005, Shoeibi 2017 and most modern migraine trials evaluate at 12 weeks. Frequency tends to drop more reliably than severity.
• Day 90 — fertility window closes. Egg maturation cycle ≈ 90 days; sperm production cycle ≈ 74 days. CoQ10 supplementation is consistently dosed for ≥90 days before the conception cycle, not during it.
• Month 6–12 — the cardiovascular endpoint. Q-SYMBIO ran 2 years. Most NYHA-class trials run ≥12 months. CoQ10 is a long-horizon cofactor for this use case, not a short-cycle product.
• On-stop reversion. Plasma drops back to baseline within 1–2 weeks of stopping. Tissue CoQ10 reverts more slowly — over months. The implication is the obvious one: cycling CoQ10 is not necessary and arguably counterproductive. Daily continuous use is the standard pattern in research and in clinical practice.

Stacking with the rest of the catalog

CoQ10 is the most "downstream" mitochondrial supplement in the True Health Protocol catalog. It supports the actual energy-production step, after the upstream NAD+ machinery and biogenesis machinery have done their work. The natural pairings:

• + NMN or NAD+ precursors — NMN raises NAD+ (upstream); CoQ10 supports ATP production (downstream). Sirtuin pathway + mitochondrial fuel, the canonical longevity stack base. Pure NMN 500 mg, NMN 1000 mg Double Strength, or Liposomal NAD+ Ultimate.
• + PQQ — PQQ helps create new mitochondria (biogenesis); CoQ10 makes sure the new ones can produce ATP. Mechanistically the cleanest CoQ10 stacking partner. PQQ 20 mg.
• + Urolithin A — Urolithin A clears the damaged mitochondria via mitophagy (PINK1/Parkin); CoQ10 powers the healthy ones that remain. The renewal/output pair. Urolithin A 500 mg.
• + Resveratrol or Pterostilbene — sirtuin-driven mitochondrial biogenesis. CoQ10 keeps the new mitochondria fed. Resveratrol 600 mg, Pterostilbene 100 mg.
• + Alpha-Lipoic Acid — ALA recycles CoQ10, vitamin C, vitamin E, and glutathione. The two of them together cover most of the mitochondrial antioxidant network. Alpha-Lipoic Acid 600 mg.
• + Calcium Alpha-Ketoglutarate — CaAKG drives the TCA cycle that feeds NADH/FADH2 into the electron transport chain; CoQ10 then carries those electrons forward. The two-step substrate-and-shuttle pair. CaAKG 1000 mg.
• + Creatine — creatine buffers cellular ATP via the phosphocreatine system, while CoQ10 supports its production. The two of them together cover most of the cellular bioenergetic stack. Creatine 1000 mg.
• + Berberine — important if you have ever been on metformin, which depletes CoQ10 in the same direction statins do (Hu 2014). Berberine HCL 500 mg.
• + Astaxanthin and Glutathione — for the fertility / egg quality stack specifically. CoQ10 powers the egg's mitochondria, astaxanthin protects the membranes, glutathione handles oxidative load. Astaxanthin 12 mg + Glutathione 500 mg.
• + Omega-3 Fish Oil — omega-3s are membrane substrate; CoQ10 lives inside that membrane. The cardiovascular pair. Omega-3 Fish Oil 2000 mg.
• + Taurine 1000 mg — taurine modifies mitochondrial tRNA to enable proper electron-transport-chain protein synthesis (Singh 2023 Science). CoQ10 then carries the electrons through that chain. The two-step "build-the-engine + fuel-the-engine" pair. Taurine 1000 mg.

Who this is for

• Adults 40+ where natural CoQ10 production has dropped noticeably
• Anyone on a statin (with their physician's awareness) — the most well-established medical use case
• Anyone on metformin, certain beta-blockers, tricyclic antidepressants, or other medications documented to deplete CoQ10
• Couples working on fertility — both partners (egg and sperm quality)
• People going through IVF cycles (under their reproductive endocrinologist's awareness)
• Athletes and recovery from intense training blocks (>5 hours/week sustained)
• Anyone running a longevity stack and wanting downstream mitochondrial support
• Recovery from illness, surgery, post-viral fatigue, periods of high mitochondrial demand
• Migraine-prone adults willing to commit to a 12-week trial
• Adults 70+ where ubiquinone-to-ubiquinol conversion may slow (a switch to ubiquinol is reasonable here, though ubiquinone at higher dose with fat still works)
• Adults with diagnosed mitochondrial dysfunction working with a specialist

Who this is NOT for

• People on warfarin without their prescriber's awareness. CoQ10 is structurally similar to vitamin K and may modestly reduce warfarin's anticoagulant effect. INR monitoring is required.
• People in active chemotherapy. CoQ10–chemotherapy interactions are mixed in the literature (some protective, some theoretically reducing efficacy). Coordinate with your oncology team — never start independently.
• People expecting same-day stimulant energy. CoQ10 is a foundational cofactor that removes a deficiency — it does not add a kick. If you want stimulant energy, look elsewhere; you will be disappointed by CoQ10 and stop too early.
• Strict vegans. Our softgel uses bovine gelatin shell. We do not currently offer a plant-cellulose CoQ10 capsule.
• Pregnant women without OB awareness. CoQ10 has been used in IVF and pre-conception protocols extensively, but data during active pregnancy is more limited. Talk to your OB before continuing through conception.
• People under 18. CoQ10 is generally regarded as safe but the studied population is overwhelmingly adult.
• People who will skip the dietary fat step. If you cannot or will not take CoQ10 with a fat-containing meal, your absorption will be a fraction of what it should be. A low-dose, food-based approach is more honest in that situation.

Common mistakes to avoid

• Taking it on an empty stomach. The single biggest absorption loss. Take it with the largest fat-containing meal of the day.
• Taking it late at night. Some people find CoQ10 mildly stimulating because it raises ATP availability. If sleep is affected, move it to breakfast or lunch.
• Buying a $9 bottle and assuming it works. Independent lab testing has repeatedly shown that a meaningful percentage of cheap CoQ10 brands contain less than half their labeled dose, and some contain the wrong (cis) isomer. Per actual milligram of bioactive trans-CoQ10, pharmaceutical-grade is usually the cheaper math.
• Quitting at week 2. CoQ10 is a long-horizon cofactor. Most studied endpoints — cardiovascular, fertility, migraine — show their effect at week 12 or later. The week-2 quitter is the single most common protocol failure.
• Stacking with a statin without telling your prescriber. Not because of risk, but because your cardiologist almost always already supports CoQ10 supplementation and may have a preferred protocol. Letting them know also keeps your medical record clean.
• Splitting a 90-day fertility window across both partners' wallets. The published fertility protocols typically dose each partner at 200–600 mg/day for 90 days. Cutting one partner out halves the effect of the protocol, not the cost of it.
• Cycling unnecessarily. CoQ10 does not downregulate. Daily continuous use is the standard. 5-on-2-off cycles or month-on-month-off cycles have no mechanistic justification and just produce uneven plasma levels.
• Switching to ubiquinol because of marketing. Unless you are over 70 or have a specific reason to suspect the conversion step is impaired, ubiquinone is the well-studied form. Ubiquinol typically costs 2–3× more for unclear added benefit in most populations.

Drug interactions and safety

• Warfarin / Coumadin. CoQ10 is structurally similar to vitamin K and may modestly reduce the effect of warfarin. If you are on warfarin, talk to your prescriber before starting CoQ10, and your INR may need to be checked again at 4–6 weeks. Not a hard contraindication; just something your physician should know about.
• Antihypertensives. CoQ10 may have a mild blood-pressure-lowering effect of its own. If you are on an antihypertensive, monitor BP for the first 6–8 weeks; doses occasionally need adjustment downward, which is a reason to coordinate with your prescriber rather than do it alone (Rosenfeldt 2007 meta-analysis).
• Chemotherapy. Some CoQ10–chemotherapy interactions are theoretical, some are protective. Always coordinate with your oncology team.
• Diabetes medication (insulin, sulfonylureas). CoQ10 may have a modest blood-sugar-lowering effect. Worth knowing if you are on insulin or a sulfonylurea so you can adjust monitoring.
• Pregnancy. CoQ10 has been used in IVF and pre-conception protocols extensively, but data during active pregnancy is more limited. Talk to your OB.
• General safety profile. CoQ10 has an excellent safety record. Trials have run up to 1,200 mg/day for 16 months in Parkinson's (Shults 2002) and up to 3,000 mg/day under medical supervision in mitochondrial encephalomyopathies, with mild GI discomfort and insomnia (when taken late) being the most reported issues. The 400 mg daily dose in this product is well within the range studied for years in fertility, cardiovascular, and migraine contexts.

FAQ

Can I take CoQ10 forever, or do I need to cycle it? CoQ10 does not downregulate the way some compounds do; long-term daily use is the standard pattern in research and in clinical practice. No cycling required.

My urine turned bright yellow — is that bad? No, that is normal and means you are absorbing it. CoQ10 is a yellow pigment; the fat-soluble surplus passes through and tints the urine.

Can I take CoQ10 if I am vegan? Our softgel uses bovine gelatin, so it is not strictly vegan. We may add a vegan capsule format in the future; for now, vegan-strict customers should look for plant-cellulose CoQ10 capsules elsewhere.

Should I take CoQ10 in the morning or evening? Morning or midday with a fat-containing meal is best. Some people find it slightly stimulating and do not sleep well if they take it after 4 pm — which makes sense, given the energy mechanism. Others have no issue with evening dosing.

Can my partner and I both take it for fertility? Yes — that is the standard protocol. Both egg quality and sperm quality benefit from CoQ10 for the same mitochondrial-energy reasons. The recommended dose for each partner is identical: 200–400 mg daily for 90+ days pre-conception.

Is 400 mg too much? No. CoQ10 has an excellent safety profile, with clinical trials running up to 1,200–3,000 mg daily in specific contexts under medical supervision. 400 mg is a therapeutic dose in the studied range — not a megadose.

Can I split the softgel? Softgels are designed to be swallowed whole, but if you only want 200 mg daily you can pierce the softgel with a clean pin and squeeze half the contents onto food (it has a slightly oily, neutral taste). Most people find it easier to just take one whole softgel every other day, which works because of CoQ10's long tissue half-life.

Why is CoQ10 so expensive in general? Pharmaceutical-grade CoQ10 is produced via fermentation, which is a slow, capital-intensive process. The cheap CoQ10 you see on Amazon is often diluted, mislabeled, or uses a synthetic isomer with much lower bioactivity. We test every batch for the trans-isomer (the bioactive form) and publish quality summaries — see the Quality & Sourcing page.

Does CoQ10 interact with statins or replace them? CoQ10 is a cofactor that statins deplete; it does not replace a statin. If you are on a statin, your physician likely already supports CoQ10 supplementation — many cardiologists recommend it routinely. Always coordinate.

Ubiquinone or ubiquinol — which one should I buy? For healthy adults under 60, ubiquinone (this product) at a meaningful dose with adequate dietary fat is the well-studied, lower-cost, well-evidenced choice. Ubiquinol is reasonable for adults 70+, advanced cardiovascular disease, or specific genetic differences in CoQ10 metabolism — situations where the conversion step itself may be impaired. The bigger absorption variable, by far, is whether you take CoQ10 with fat.

Does CoQ10 help with long COVID or post-viral fatigue? Open question. There is plausible mechanism (mitochondrial dysfunction is a documented feature of long COVID) and a small handful of pilot studies, but no large RCTs yet. Many post-viral fatigue clinicians include CoQ10 in their stacks; the evidence is not yet at the level of the cardiovascular or fertility data.

Is CoQ10 the same as Q10 or coenzyme Q? Yes — all three names refer to the same molecule. "Q" comes from the historical name "ubiquinone" (because it is ubiquitous in tissues). The 10 refers to its 10-unit isoprenoid side chain.

Can I take CoQ10 with my morning coffee or NAD+ stack? Yes. CoQ10 does not interact meaningfully with caffeine, NMN, NR, resveratrol, or the rest of the NAD+ stack. Just make sure the CoQ10 is taken with a fat-containing meal — a coffee-only breakfast does not count.

Does CoQ10 help with thyroid energy issues? A small literature suggests CoQ10 levels are lower in hypothyroid patients (Mancini 1989), and supplementation has been included in some functional-medicine protocols. Talk to your endocrinologist; this is more "supportive cofactor" than treatment.

How does this product compare to the CoQ10 I see in the NAD+ 5-in-1 formula? The 5-in-1 includes a smaller CoQ10 dose alongside NMN, B-complex, and antioxidants for an all-in-one daily. This standalone 400 mg softgel is what you reach for when you want a higher therapeutic dose specifically — fertility cycles, statin replacement, athletic recovery, migraine prevention, or stacking on top of your core NAD+ protocol.

Why bovine gelatin softgel and not vegan capsule? CoQ10 is fat-soluble; bioavailability is dramatically higher when delivered in a fat-carrier softgel rather than a dry powder capsule. Hard-shell vegan CoQ10 capsules exist but typically need 2–3× the dose to match the same plasma exposure.

Directions

Take 1 softgel daily with a meal containing some fat — eggs, avocado, full-fat yogurt, butter on toast, olive oil, full-fat dairy. Lunch or dinner usually works better than breakfast for higher fat content. CoQ10 absorption drops dramatically on an empty stomach (Hidaka 2008; Lopez-Lluch 2011). Daily consistency matters more than dose timing. For fertility protocols, take consistently for 90+ days before the conception cycle. For migraine prevention, evaluate at 12 weeks. For statin support, take on the same daily schedule as the statin.

Sourcing, manufacturing, and QC

• cGMP-certified, FDA-registered facility, manufactured in the USA. ISO 9001 quality system.
• Per-batch HPLC verification for ≥98% trans-isomer purity (the bioactive form). Cis-isomer content reported on the COA.
• Per-batch heavy metals testing per USP <2232> (lead, arsenic, cadmium, mercury) to specification.
• Per-batch microbial limits testing per USP <2021/2022> (total aerobic, yeast/mold, E. coli, Salmonella, S. aureus).
• Per-batch residual solvents per USP <467> — meaningful given fermentation-derived CoQ10 production.
• Per-batch pesticide screening per USP <561> on the carrier oil.
• Oxidation protection via mixed tocopherols in the softgel matrix and amber HDPE bottle.
• 24-month shelf life from manufacture date (printed on bottom of bottle).
• COA available on request. See the Quality & Sourcing page and Ingredient Sourcing page for detail on every active in the catalog.

Storage and quality

Store in a cool, dry place away from direct sunlight. CoQ10 in softgel form is stable at room temperature; refrigeration is not required but does not hurt. Avoid leaving the bottle in a hot car or near a stove. Best-by date is printed on the bottom of the bottle — typically 24 months from manufacture.

Why not Amazon

• Per-batch HPLC for trans-isomer purity. Independent lab audits of CoQ10 marketplaces have repeatedly found products with less than half their labeled dose, or with the wrong (cis) isomer that has much lower bioactivity. Trans-isomer purity is reported on every batch we ship.
• Pharmaceutical-grade fermentation-derived CoQ10. Not synthetic, not blended with cheaper isomers, not "CoQ10 complex" with undeclared filler.
• Catalog architecture. CoQ10 is one cofactor in a larger mitochondrial story (NAD+ upstream → biogenesis via PQQ → mitophagy via Urolithin A → fueling via CoQ10). The catalog is built so each piece has a defensible reason to be there.
