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.
Resveratrol's more bioavailable cousin, mostly used in blends.
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.
Consumer signals gathered from 1 platform.
Low confidence, small sampleConsumer sentiment compiled from 1 public source (ConsumerLab). Small sample size, treat as directional only.
positive sentiment
Compiled from a ConsumerLab 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.
Public sources on this same product, unrelated to NO1GEVITY. NIH DSLD is the US government's registered label database (shown verbatim). SuppCo.com is a separate, unaffiliated commercial site with no partnership or data-sharing arrangement with us. NO1GEVITY scores are computed independently of both.
SuppCo is a separate, unaffiliated supplement-tracking site with no partnership, data-sharing agreement, or business relationship with NO1GEVITY. We are not endorsed by them and they do not endorse us. The two facts below are individually verified against the manufacturer or NSF; the outbound link is provided only so readers can independently cross-check on a third-party site if they want to.
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.
ConsumerLab finds resveratrol purity/label-accuracy has improved industry-wide, but considers the health-benefit evidence for most popularly promoted uses (cardiovascular, cholesterol, insulin sensitivity, memory, 'life-extension') to be limited and sometimes contradictory, with the strongest (still preliminary) support being for age-related macular degeneration.
Innerbody's company-level review is generally balanced: positions Life Extension as a legitimate, moderately-priced, research-oriented brand, but flags a thin and mixed customer-review sample and notes complaints about side effects and shipping/lab-result delays.
Credentialed commentary from clinicians who disclose no paid relationship. Useful as supporting critique but not a substitute for a clinical outcome trial.
Mostly positive sentiment on product quality and customer service, with a consistent minority of fulfillment/logistics complaints.
More critical than Innerbody's take: highlights user complaints about receiving wrong orders, side effects/headaches attributed to produkter, absence of publicly posted lab-test documents on the website, and references the 2017 FDA warning letter as a compliance concern.
Additional public mentions we located, kept separate from the deep independent reviews above.
Passed ConsumerLab category testing for resveratrol content and purity.
