Tru Niagen is a different kind of product than most of what we cover: a single, patented ingredient (Niagen® nicotinamide riboside) made by a real, publicly traded company, backed by multiple independent, peer-reviewed human trials — not just one manufacturer-funded study. It’s also surrounded by the same kind of imitator-domain confusion we’ve flagged with other products. Here’s what’s actually verified.
What’s in Tru Niagen
This is a single-ingredient formula — genuinely simple to evaluate, since there’s no blend to hide anything in.
| Product | Niagen® (NR) Dose |
|---|---|
| Tru Niagen 150mg | 150 mg |
| Tru Niagen 300mg (standard) | 300 mg |
| Tru Niagen Pro 1,000mg | 1,000 mg |
Niagen® is a patented, standardized form of nicotinamide riboside (NR) — a vitamin B3 derivative that the body converts into NAD+, a molecule involved in cellular energy production and DNA repair that declines with age. The company states over 75% of published peer-reviewed studies on NR specifically use Niagen®.
What the Clinical Evidence Actually Shows
This is the strongest evidence base we’ve found for any product on this site, largely because it includes research that isn’t funded by the manufacturer.
Worth being precise about the distinction: the independent university study and the company-funded studies reach similar conclusions, which is a genuine point in Tru Niagen’s favor — but readers should know which is which rather than assume all cited research is equally unbiased. All of this evidence is about raising blood NAD+ levels specifically. Evidence connecting that increase to longer-term outcomes like slower aging or reduced disease risk in humans is still an active area of research, not yet conclusively established.
What Real Customers Say
We don’t invent review counts. Tru Niagen’s Trustpilot page has a genuinely small sample.
What we found worth flagging specifically: one detailed report describing a fast heart rate, acne, and skin itching that resolved after stopping use; a separate report of bottles arriving with broken glass inside damaged shipping packaging; and recurring complaints about difficulty cancelling a subscription. Positive reviews commonly come from long-term users (some citing 6+ years of continuous use) reporting sustained energy and general wellbeing. Read the reviews yourself on Trustpilot ›
Editorial Concerns
- Small independent review sample makes the star rating less statistically reliable than for higher-volume products
- A specific, detailed adverse-reaction report and a shipping-damage/injury report both appear in the available reviews
- Recurring subscription-cancellation complaints
- Evidence firmly establishes NAD+ increases; evidence for downstream anti-aging or disease-prevention outcomes in humans is still developing
Who Should Not Take This
- Anyone under 18, pregnant, or breastfeeding
- Anyone with a history of cancer — NAD+ pathways are involved in cell growth signaling, an area still being actively researched
- Anyone who has experienced a skin or cardiovascular reaction to a similar supplement before
- Anyone expecting a broad “anti-aging” transformation the current human evidence doesn’t yet fully demonstrate
This isn’t medical advice — talk to a healthcare provider before starting any supplement, especially if you have an existing health condition or take medication.

Pros & Cons
Pros
- Simple, fully disclosed dose — no proprietary blend

- NSF Certified for Sport and third-party lab tested

- Evidence covers NAD+ elevation, not yet long-term anti-aging outcomes
Who It’s For
Tru Niagen fits someone who wants the most scientifically well-supported NAD+ precursor on the market, from a real, accountable company, and who understands the evidence currently supports raised NAD+ levels specifically rather than a broader anti-aging guarantee. Buy from truniagen.com directly, and consider starting at the standard 300mg dose rather than jumping to the 1,000mg Pro serving.
FAQ
Is the research behind Tru Niagen independent or company-funded?
Both exist. The Martens et al. 2018 study (Nature Communications) was independently funded and conducted at the University of Colorado Boulder. Other key studies, including the dose-ranging Conze et al. 2019 trial, were funded by the manufacturer. Both are peer-reviewed and reach similar conclusions.
Does raising NAD+ actually slow aging?
The evidence solidly establishes that NR supplementation raises blood NAD+ levels in a dose-dependent way. Evidence connecting that increase directly to slower aging or reduced disease risk in humans is still developing, not yet conclusively proven.
How do I know I’m buying from the real site?
Use truniagen.com specifically. We found similarly-named domains using nearly identical marketing copy during this review — verify the exact domain before entering payment details.
Do I need a prescription?
No. Tru Niagen is an over-the-counter dietary supplement, not a prescription medication, and isn’t a substitute for one.
