Spermidin 3mg
How we scored this product Show the full breakdown
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.

Why this scored this way
This Supersmart Spermidin 3mg scores 5.6, making it below the site average. It delivers the full 3mg trial dose of Spermidin with grade B evidence (promising human data, not yet comprehensive). The quality transparency (5.0) is limited by the lack of third-party testing. At $0.28/day it's priced well for what you get.
What drives the score up
