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.

  • Jiang et al. 2026 (npj Aging) (Spermidine)Comprehensive review identifying eIF5A-TFEB axis as central autophagy mechanism. SmartAge Phase IIb showed no memory improvement at 12 months. 3.3 mg/day rice germ extract improved cardiometabolic biomarkers. 40 mg/day high-purity spermidine safe for 28 days in older men. Studied at 40 mg. This product: 10 mg.

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.

What drags it down
