Frequently Asked Questions

How are evidence grades assigned?
A: Multiple RCTs + meta-analyses with consistent positive effect (e.g. creatine for strength). B: Some RCTs, mostly positive, mechanism plausible (e.g. omega-3). C: Mixed evidence or only mechanistic / animal data (e.g. ashwagandha). D: Mostly preclinical, marketing-led, or human studies show null effect (e.g. NMN for longevity in humans).
Why is the supplement industry so misleading?
$160B/year, mostly unregulated. Brands pay influencers, sponsor "studies", confuse mechanism with outcome. Bryan Johnson takes 100+ supplements; most have D-grade evidence. Healthspan = exercise + sleep + diet > all supplements combined.
Which supplements are actually worth it?
A-grade for most: creatine 5g/day, vitamin D (if deficient), omega-3 (if not eating fish 2×/wk). B-grade: magnesium glycinate, fiber if low intake, protein powder if struggling to hit target. Everything else: case-by-case.
