The 6 Health Britannica metrics

Every supplement is scored across the same six proposition values. This system gives you an objective, repeatable way to compare any product across any category.

Metric 01
Evidence
Strength of clinical research. Systematic reviews and RCTs weighted highest, anecdotal lowest.
Metric 02
Purity
Third-party testing, heavy metal screening, label accuracy. Does the bottle match the claim?
Metric 03
Value
Cost per clinically effective dose versus competitors. Premium justified or cheaper equal exists?
Metric 04
Efficacy
Does the product deliver the researched dose in a bioavailable form at the stated potency?
Metric 05
Safety
Side effect profile, drug interactions, long-term safety data. Conservative risk assessment.
Metric 06
Synergy
How well it integrates with other stack supplements. Absorption enhancers, cofactors, timing.
