Bevisning 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. Säkerhet 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.
The specific product: dose, price, transparency, and what buyers report.

Reddit users in the brand subreddit note that Magtein is a patented, licensed magnesium L-threonate, so most branded versions are functionally similar. Some commenters say Nootropics Depot's version is fairly priced for the dose, while others point to cheaper alternatives like Jarrow MagMind or Life Extension Neuro-Mag.
Examine's magnesium page notes decent evidence for blood sugar and blood pressure benefits but calls the sleep evidence surprisingly thin. A separate Examine FAQ says a magnesium and sleep metaanalys found only a modest cut in sleep latency, with the authors calling current evidence insufficient for strong recommendations.
