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.

All product data is checked against original sources. Prices, doses, and testing status are updated when product pages change. Bevisning grades are reviewed when new human RCTs are published. Read how we verify.
What's inside
Consumer signals
Consumer signals gathered from 1 platform.
Low confidence, small sampleConsumer sentiment compiled from 1 public source (Examine.com). Small sample size, treat as directional only.
positive sentiment
Compiled from a Examine.com listing located during manual research; not independently re-verified against the live page at build time.
These are consumer sentiment signals. They do not measure whether the product actually works. See our evidence section for that.
What others say, with a source hierarchy
We treat external opinion very differently depending on where it comes from. Tier A is our strongest signal. Tier C is background sentiment only. Tier Rejected is what we excluded, listed openly so you can see what we discarded.
These reviews are aggregated from third-party sources, not written by NO1GEVITY. Each entry shows its source, retrieval date, and whether the source has an affiliate or paid relationship. We do not edit reviews to change their meaning. Disclosure policy.
Registered dietitians and physicians, without affiliate ties
Credentialed commentary from clinicians who disclose no paid relationship. Useful as supporting critique but not a substitute for a clinical outcome trial.

What we could not verify
We list this openly. If a claim isn't backed by a source we can trace, we'd rather flag it than repeat it.
- The specific claim that berberine's effect on the NADH/NAD+ ratio meaningfully undermines simultaneous NMN/NR supplementation in humans, at consumer-relevant doses, was not independently confirmed against the primär Toxicology Letters source.
- Whether DoNotAge's specific berberine extract has been tested in any registered clinical trial (as opposed to generic berberine HCl from other suppliers) was not confirmed.
