These calculations describe our scoring method. They are not a recommended dose or proof of benefit from this product.
Public lab certificate, tested by independent lab, top 23% value.
Read the evidence (2 studies)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.
This ProHealth Longevity Pure Spermidine - 1 mg, 180 capsules scores 7.1, making it a mid-tier product with both strengths and weaknesses. It delivers 1mg of Spermidine, inside the studied range of 0–6mg with grade C evidence (mostly preclinical, limited human data). Transparency is a clear strength (score: 9.0), with third-party testing and a public lab certificate. At $0.20/day it's priced well for what you get.
