Our analysis

Excellent (83/100) - Effectiveness scored 75 due to solid RCT evidence for heart health (e.g., meta-analysis showing 3g/day benefits in CHF patients) but limited data for general longevity or healthy adults; mouse studies promising but not human-translatable yet. Bryan Johnson's 3g dose aligns with effective ranges (1-6g), and 1000mg capsules allow flexible dosing. Safety near-perfect at 97 as taurine has excellent tolerability profile across 50+ studies, with no dose-limiting toxicity up to 10g/day acutely. Quality at 90 reflects ConsumerLab's positive taurine testing (passing purity/potency) and NOW's rigorous internal program highlighted in FDA correspondence, though lacks NSF/USP seals. Overall 82 balances proven niche benefits against broad claims.
