Read the full evidence vaultEvidence 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 Cycloastragenol - 10 mg, 30 capsules scores 5.2, making it among the lowest-scoring products we track. It delivers 10mg of NAC, 1% of the studied range low edge (600mg) with grade B evidence (promising human data, not yet comprehensive). Transparency is a clear strength (score: 9.0), with third-party testing and a public lab certificate. At $69.94/day it's among the more expensive options in Antioxidant.
