Longevity Supplements 2026: The Independent Ranking

NAD+ precursors (NMN, NR), omega-3, magnesium, vitamin D, and creatine have the strongest human evidence. NAD+ precursors raise blood NAD+ 40 to 60 percent at 300 to 500 mg per day. Omega-3 at 2 to 4 grams EPA+DHA reduces triglycerides. Magnesium at 300 to 400 mg supports sleep and blood pressure. Vitamin D at 1,000 to 4,000 IU corrects deficiency. Creatine at 5 g daily has 500+ trials for muscle, strength, and cognition.

Omega-3 has over 40,000 published studies. Creatine has 500+ RCTs. Vitamin D has 20,000+ trials. Berberine has 100+ human RCTs for blood glucose control. NMN and NR have 20+ human RCTs combined. Rapamycin (prescription-only) has ongoing PEARL and RAP-PATH trials but no completed longevity RCTs yet.

No supplement is FDA approved for extending lifespan. FDA regulates supplements as food, not drugs. Some (NR, magnesium, creatine) are FDA-GRAS (Generally Recognized As Safe). NMN was reclassified as a drug candidate in 2022, though enforcement is minimal. Rapamycin and metformin are prescription drugs used off-label for longevity by some clinicians.

Basic stack (omega-3, magnesium, vitamin D, creatine): $30 to $50 per month. Full stack with NAD+ precursor, resveratrol, and additional actives: $150 to $300 per month. Bryan Johnson-style Blueprint stack: $1,000+ per month. Cost varies 3 to 5x between generic and premium brands at the same dose.

Most are safe at recommended doses. Common risks: fish oil at high doses can raise atrial fibrillation risk. Iron supplementation without deficiency raises oxidative stress. High-dose vitamin E (400+ IU) may increase mortality per meta-analyses. Berberine interacts with metformin and statins via CYP3A4. Rapamycin has significant immunosuppressive effects. Always check drug interactions with a physician.

Start with omega-3 (2 g EPA+DHA), magnesium glycinate (300 mg), and vitamin D3 (2,000 IU). These have the strongest evidence, lowest cost ($20 to $30 per month total), and near-zero interaction risk. Add creatine (5 g) for muscle and cognition. Add NR or NMN (300 mg) only after baseline is stable.

We do not accept affiliate commissions, sponsored placements, or brand payments. Products are scored using a public 6-pillar formula: dose vs trial dose, evidence grade, third-party testing, transparency, price per trial-day, and community sentiment. The scoring code is open. Every study cited is fetched from PubMed and verified.

His Blueprint protocol as of 2026 includes NMN or NR, rapamycin (physician-supervised), collagen peptides, taurine, glucosamine, spermidine, and dozens of others. Total daily supplement burden is 100+ pills. His self-reported biological age reversal has been contested by critics including Charles Brenner and Peter Attia.
