How we define value
Value is cost per serving for a product that already meets our documentation standard: a batch-specific COA covering metals and microbiology, no results above GB limits[1] and matched identity. A cheaper product without that evidence isn’t better value, because you can’t tell what you’re paying for.
Current status
Value comparisons need verified, dated prices for more than one evaluated product, recorded under our price methodology. One product has completed our evaluation so far, the Nature Elixirs resin. Ranked value comparisons appear here once more products are evaluated.
