What to check on the label

  • Whether every ingredient has its own milligram line, or several are grouped in a 'blend' with one total.
  • How many capsules or scoops make a serving, and how many servings the container holds.
  • Whether the ingredients you care about appear at amounts you would accept on their own. The list below shows each figure.

Amounts are per label serving as recorded in the catalog and are not a recommendation. Testing status reflects what the brand lists. Nothing here is medical advice.

Evidence gates dose: the evidence grade sets the ceiling, and the dose decides how much of that ceiling the product reaches. Value = inverse of price-per-trial-dose-day. Community = mean sentiment of external reviews. Safety caps applied after weighting.

This score is our editorial judgment, not a scientific standard. We combine published evidence, dose, price, transparency, and consumer signals into one composite: this is our method, not a peer-reviewed clinical rating. A higher score means a product does better on the factors we weight, not that it is medically proven to work.

Important to know
C15:0The healthiest cohorts get C15:0 from dairy fat — the supplement story assumes the molecule, not the milk matrix, is the active agent. That assumption is untested in human trials.
