What to check on the label

  • Which form of the compound the label names (for CoQ10: ubiquinol or ubiquinone) and whether the milligrams refer to that form.
  • Softgel oil carriers are listed under 'other ingredients'. They are not part of the active amount.
  • Branded ingredients (Mitopure, BioPQQ and similar) should be named on the label if the brand claims them.

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.

How we scored this product Show the full breakdown
Dose vs. studies (50%) Why 3.0 of 10. Primary ingredient is C15:0 (evidence grade D). It delivers 100 mg, inside the studied range of 100–200 mg. Read the rule → 3.0
Transparency (20%) Why 7.0 of 10. Earned points for independent third-party testing and all doses disclosed. Lost points for no public certificate of analysis. Read the rule → 7.0
Value (10%) Why 7.8 of 10. One day at the trial dose costs about $1.67. That is more expensive than average (173 of 313 by cost per effective day). Read the rule → 7.8
Formulation (10%) Why 5.0 of 10. No published absorption advantage or disadvantage on file. The default of 5 is not a criticism. Read the rule → 5.0 Default. No absorption data on file.
Safety (5%) Why 7.0 of 10. Baseline 5.0. Third-party testing adds 2.0. Public lab certificate adds 1.5. NSF, USP or Informed Choice certification adds 1.5. Active safety signal subtracts 3.0. Read the rule → 7.0
Community sentiment (5%) Why 7.1 of 10. No external reviews found, so community sentiment defaults to neutral. Community never counts as clinical evidence. Read the rule → 7.1
Composite How this 4.9 is built. 0.50 × 3.0 + 0.20 × 7.0 + 0.10 × 7.8 + 0.10 × 5.0 + 0.05 × 7.0 + 0.05 × 7.1 = 4.9 out of 10. Safety caps applied after. 4.9

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.

C15:0C15:0 as candidate essential fatty acid (2023)
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.
