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 |
|---|---|
| NR | 300 mg |
| Betaine (TMG) | 100 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.
Public lab certificate, tested by independent lab.
Read the evidence (2 studies)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 ProHealth Longevity Nicotinamide Riboside Pro 300 + 100mg TMG scores 7.5, making it a strong scorer. It delivers 300mg of NR, inside the studied range of 100–1000mg with grade B evidence (promising human data, not yet comprehensive). Transparency is a clear strength (score: 9.0), with third-party testing and a public lab certificate.
The science behind each active ingredient, independent of which brand sells it.
The NAD+ precursor with the strongest safety file and EU approval.
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 |
|---|---|---|---|---|
| NR | 300 mg | 300 mg | 100% | B |
| Betaine (TMG) | 100 mg | 3000 mg | 3% | 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 →

A straightforward 300mg NR capsule bundled with 100mg TMG (to support methylation/offset niacin-pathway methyl depletion), reasonably dosed and clearly labeled, though price was not confirmed from the vendor directly.
