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 12% 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.

Directly longevity-positioned per the brief's criteria, the vendor's own marketing explicitly cites the 2023 Science paper line of research on taurine decline and lifespan. 1000mg/day is a reasonable starting dose versus the 3000mg+ used in some rodent-to-human extrapolated protocols.
