Supplements buyer FAQ
What supplements should I actually take for longevity?
The high-evidence foundational stack: creatine monohydrate (most-studied performance + cognitive supplement), vitamin D + K2 (especially in low-sun latitudes), magnesium (any of the 7 forms BiOptimizers covers), omega-3, and a clinician-vetted multivitamin like Thorne Basic Nutrients 2/Day. Beyond foundational, evidence drops sharply - NMN, urolithin A, and niacin precursors have promising-but-incomplete human data. Always run labs first and supplement based on actual deficiencies, not protocol-stack mimicry.
AG1 vs Thorne - is it worth the premium?
AG1 ($79-99/mo subscription) is a comprehensive greens powder with 75+ ingredients. Thorne Basic Nutrients 2/Day ($35) is a focused multivitamin covering the same essential vitamin/mineral panel as AG1. Thorne is NSF Certified for Sport (banned-substance tested); AG1 isn't. For pure cost-effectiveness on the multi/mineral component, Thorne wins by a wide margin. For the convenience + adaptogen + greens layer, AG1's premium has a real consumer audience. Most clinicians we know prefer Thorne or Momentous for the foundational tier.
Are NAD+ precursors (NMN, NR) actually worth taking?
NMN and NR (Tru Niagen) are the most-marketed longevity supplements after the David Sinclair work, but the human clinical evidence is genuinely incomplete. Cell-line and animal data show NAD+ levels increase with supplementation; clinical outcomes (lifespan, healthspan markers) in humans are still being studied. The honest framing: NMN and NR are reasonable bets on emerging science, not proven longevity interventions. If budget allows, they fit in a longevity stack; if budget is tight, the foundational stack (creatine, vit D, omega-3, magnesium) has stronger evidence per dollar.
Should I bother with the Bryan Johnson Blueprint stack?
Blueprint ($354/mo) is the most comprehensive longevity supplement bundle on the market - 12+ products, 100+ ingredients, designed by Bryan Johnson's team and tracked across his own biomarkers. The case for: it's the most-tested single stack in the category by a single user. The case against: Bryan Johnson is one person, and what works for his physiology may not transfer to yours. For buyers wanting a turnkey premium stack and the brand-experience component, Blueprint delivers. For evidence-per-dollar, the foundational stack from Thorne + Momentous + LMNT covers 80% of the practical benefit at 25% of the cost.
