These calculations describe our scoring method. They are not a recommended dose or proof of benefit from this product.
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 Supersmart Calcium AKG scores 4.6, making it among the lowest-scoring products we track. It delivers 1000mg of Ca-AKG, inside the studied range of 300–2000mg with grade D evidence (very early-stage, mostly animal models). The quality transparency (5.5) is limited by the lack of third-party testing. At $3.30/day it's among the more expensive options in Metabolic.
