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.

Redaktionellt notes
Physician-developed (Harvard MD Andrew Salzman) 900mg NMN stack with ergothioneine, trans-resveratrol and hydroxytyrosol; 2-capsule daily serving.
Why this scored this way
This Wonderfeel Youngr NMN scores 5.9, making it below the site average. It contains 0.02mg of Vitamin D3, which is only 40% of the 0.05mg trial dose with grade A evidence (strong human trial data). At $1.63/day it's among the more expensive options in NAD+ booster.
What drives the score up
- Tested by independent lab (transparency 7.5).
- NMN is dosed at the full research level with grade B evidence (promising human data, not yet comprehensive).
- NMN is also dosed at the full research level.
What drags it down
- Dose-evidence score of 5.1 is below average for the site.
- Ergothioneine (4mg is 40% of the 10mg trial dose) is significantly under-dosed.
- Resveratrol (100mg is 20% of the 500mg trial dose) is significantly under-dosed.
- Vitamin D3 (0.02mg is 40% of the 0.05mg trial dose) is significantly under-dosed.
- NMN (900mg is 180% of the 500mg trial dose) is well above the trial dose. More is not always better.
Why you'd choose it
- You want Vitamin D3 from a Wonderfeel product.
- You want a tested by independent lab product.
Why you might skip it
- You want a product with a publicly available CoA.
- You need a full trial dose of ergothioneine (this product under-doses it).
- You want a standard dose of nmn (this product is well above it).
