What to check on the label

  • Read the spermidine line, not the extract line. '800 mg wheat-germ extract' may contain only a few milligrams of spermidine.
  • Check the serving size. Capsule counts per serving vary from one to three.
  • If wheat-germ based, the label states gluten content. The catalog does not store allergen data.

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.

Why this scored this way

This BulkSupplements Fisetin Powder scores 5.9, making it below the site average. It delivers 100mg of Fisetin, inside the studied range of 100–1400mg with grade C evidence (mostly preclinical, limited human data). The quality transparency (6.0) is limited by the lack of third-party testing.

What drives the score up

  • Overall score of 5.9 with no single dominant strength.

What drags it down

  • Dose-evidence score of 5.4 is below average for the site.
  • Fisetin (100.0mg is 20% of the 500mg trial dose) is significantly under-dosed.
  • No third-party testing, which caps the quality transparency.
  • Quality transparency of 6.0 is below the site average.

Why you'd choose it

  • You want a reasonably priced autophagy product.

Why you might skip it

  • You want third-party verified purity.
  • You want a product with a publicly available CoA.
  • You need a full trial dose of fisetin (this product under-doses it).

Editorial notes

100mg/serving is a maintenance-style dose, well below the ~20mg/kg senolytic protocol doses used in early human trials, useful only if the buyer plans to stack multiple servings for a senolytic-style regimen.
