Label snapshot
What the product contains and what one serving costs, according to our catalog. Label amounts are not personal dose recommendations.
| Ingredient | Amount per serving |
|---|---|
| NMN | 50 mg |
| Betaine (TMG) | 50 mg |
Amounts are per label serving as recorded in the catalog and are not a recommendation. Testing status reflects what the brand lists. Nothing here is medical advice.
These calculations describe our scoring method. They are not a recommended dose or proof of benefit from this product.
Evidence 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. Safety 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.
This Quicksilver Scientific NAD+ Gold scores 4.7, making it among the lowest-scoring products we track. It delivers 50mg of NMN, 20% of the studied range low edge (250mg) with grade B evidence (promising human data, not yet comprehensive). At $17.80/day it's among the more expensive options in NAD+ booster.
The science behind each active ingredient, independent of which brand sells it.
A NAD+ building block that has become the most-hyped longevity molecule.
A methyl donor added to NAD+ formulas as a supporting cofactor, not a headline active.
Every active in this formula, its declared dose per serving, the dose used in the primary human trial, how much of that trial dose this product delivers, and the evidence grade for the ingredient itself.
| Ingredient | Dose / serving | Research dose | % of research | Evidence grade |
|---|---|---|---|---|
| NMN | 50 mg | 500 mg | 10% | B |
| Betaine (TMG) | 50 mg | 3000 mg | 2% | C |
Percentages are dose per serving ÷ primary trial dose. Below 50% means the formula is unlikely to reproduce the trial outcome for that active. Grade A = multiple large human RCTs. Grade F = no human evidence. How grades work. Full glossary →
