Label snapshot
What the product contains and what one serving costs, according to our catalog. Label amounts are not personal dose recommendations.
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 Tru Niagen (ChromaDex) Tru Niagen Immune scores 6.6, making it a mid-tier product with both strengths and weaknesses. It delivers 20mg of Zinc, inside the studied range of 10–30mg with grade A evidence (strong human trial data). The quality transparency (5.0) is limited by the lack of third-party testing. At $2.73/day it's among the more expensive options in Vitamin.
The science behind each active ingredient, independent of which brand sells it.
The NAD+ precursor with the strongest safety file and EU approval.
Correcting deficiency is important; megadoses rarely add benefit.
Essential mineral for immunity and skin; watch out for copper depletion.
Turmeric's active compound; genuinely anti-inflammatory but only in absorbable forms.
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 | 150 mg | 300 mg | 50% | B |
| Vitamin C | 180 mg | 500 mg | 36% | A |
| Zinc | 20 mg | 15 mg | 133% | A |
| Curcumin | 30 mg | 1000 mg | 3% | B |
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 genuine combination product pairing 150mg NR with vitamin D3, vitamin C, zinc, and Theracurmin curcumin, the closest thing in the current lineup to a 'longevity multivitamin,' but the NR dose is half the standard 300mg serving, so it's best understood as a stacking companion rather than a primary NAD+ product.
