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 science behind each active ingredient, independent of which brand sells it.
The famous red-wine molecule; longevity claims have outrun the human evidence.
The 'sunscreen from within' with real skin, eye, and endurance data.
The specific product: dose, price, transparency, and what buyers report.
Säkerhet flags, transparency gaps, dosing concerns, and recurring buyer complaints.
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.

These are consumer sentiment signals. They do not measure whether the product actually works. See our evidence section for that.
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.
Our strongest external evidence. Long-form independent reviews, physical-product lab work, and third-party certifications.
Well-formulated: most ingredients delivered at clinically relevant doses (glycine 3000 mg, taurine 2000 mg, NMN 300 mg, fisetin 100 mg).
A physiologist at Universidad Rey Juan Carlos argues IM8's 'kitchen sink' strategy violates the basic supplement principle of 'only take what you need'. El País also notes IM8 stopped shipping to Spanish customers shortly after the paper contacted the company.
Named experts describe the Beckham-branded supplements as 'meaningless nonsense' for failing to disclose per-ingredient doses.
Credentialed commentary from clinicians who disclose no paid relationship. Useful as supporting critique but not a substitute for a clinical outcome trial.
Independent dietitian walks through the label; flags underdosing on several actives and questions the value of blends without listed amounts.
Adds up IM8's amino-acid blend: 1.58 g total. Muscle protein synthesis normally needs ≥2-3 g of leucine alone, so the blend cannot plausibly drive the outcomes it is marketed toward.
Mood indicator only. We never use aggregate stars as evidence of efficacy.
Aggregate score ≈ 4.5-4.6 / 5. Mood indicator only.
Marketing-quoted press, obviously fabricated aggregate ratings, or heavy-affiliate 'reviews'. Listed openly so you can see what we excluded.
Business journalism, not product testing. IM8 and NOVOS both quote Forbes on their own marketing pages.
Fabricated-looking average ratings and heavy affiliate links. Not usable as evidence at any tier.
Longevity brands rarely test their exact finished product. We separate what's tested from what's inferred.

We list this openly. If a claim isn't backed by a source we can trace, we'd rather flag it than repeat it.
Ten longevity actives at moderate doses. NMN 300mg is 30-60% of the DoNotAge dose.
This IM8 Daily Ultimate Longevity scores 5.7, 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). At $4.97/day it's among the more expensive options in Longevity stack.
