Tru Niagen - Nicotinamide Riboside (NIAGEN)
The patented NR supplement from ChromaDex - the most clinically-trialed NAD+ precursor, $50-90/month.
The NAD+ precursor that came with the patent and the published trials - ChromaDex's NIAGEN is the most-studied NR on the market, sold direct as Tru Niagen.
If NMN gets the Sinclair-podcast attention, NR (nicotinamide riboside) gets the trial publications. ChromaDex's patented NIAGEN compound has been the subject of ~30+ peer-reviewed human trials - including studies tracking blood NAD+ levels, mitochondrial markers, and cardiovascular biomarkers.
The NR vs NMN debate is one of the most contested arguments in the longevity supplement category. Both convert to NAD+ via different pathways. NMN advocates argue for direct NAD+ precursor dosing. NR advocates argue NIAGEN has the actual published human trials. What's clear: NR has a longer commercial history (since ~2013), more institutional research, and FDA NDI / GRAS notification - none of which NMN currently has.
Where it wins: published evidence at the dose sold. ChromaDex has funded or partnered on ~30+ human trials of NIAGEN. The 300mg dose at ~$50/mo subscribed lands in same price range as Mitopure but with longer evidence base. Sold in CVS, Mayo Clinic research partnerships - institutional credibility most longevity supplements lack.
Where it loses: marketing is conservative to the point of being inaccessible. Tru Niagen messaging is regulatory-compliant ("supports cellular energy") rather than mechanistic, which makes it harder for consumers to understand why they'd buy it vs NMN. Brand has been less effective than NOVOS or Timeline at communicating to longevity-pro buyers.
FDA / regulatory context: NR has both NDI and GRAS status - credentials NMN currently lacks following the FDA's 2022 reclassification of NMN. NR can be sold and shipped freely; NMN exists in a gray zone in the U.S. market.
Evidence-first buyers who prioritize the most-studied NAD+ precursor with FDA NDI / GRAS status, and longevity-pro buyers who want institutional brand credibility.
You specifically want NMN (different precursor pathway), you're tracking aggressive Sinclair-style protocols, or you find the conservative messaging insufficient.

Tru Niagen Tru Niagen (300mg NIAGEN) - buyer FAQ
NR vs NMN - which one is better?
Both convert to NAD+, the cellular energy molecule that declines with age. NR has 30+ peer-reviewed human trials and FDA NDI + GRAS regulatory status. NMN has the Sinclair-podcast attention but less institutional research and exists in an FDA gray zone after the 2022 reclassification. If you want the most-studied compound at the dose sold, NR (Tru Niagen). If you want the buzzy Sinclair-favored precursor, NMN. Many longevity-pro buyers stack both.
Why is Tru Niagen more expensive than generic NR?
Tru Niagen uses NIAGEN - ChromaDex's patented form of NR. The patent covers the synthesis process that produced the compound used in ~30+ published trials. Generic NR from other brands may use different synthesis pathways and doesn't carry the same evidence base. Whether the patent premium is worth it depends on how much you value matching the exact compound tested in studies.
What dose should I take - 300mg or 600mg (Pro)?
300mg is the dose used in most published trials and the standard recommendation. 600mg "Pro" is for users who want to layer additional NAD+ precursor on top - similar approach to Sinclair's reported 1000mg+ protocols. Diminishing returns above 600mg are likely. Start at 300mg, evaluate over 90 days, then consider Pro tier only if you have baseline measurements.
Is NR safe long-term?
Yes, based on available data. NR has FDA NDI (New Dietary Ingredient) notification and GRAS (Generally Recognized As Safe) status - regulatory credentials NMN currently lacks. Trials up to 1+ year have shown clean safety profiles in healthy adults. People on chemotherapy or with specific liver conditions should consult their physician first.
When should I take Tru Niagen?
Most trial protocols use morning dosing with food. Some users report better tolerance taking it earlier in the day rather than evening (anecdotally - some people report mild sleep disruption from late-day NAD+ elevation, similar to caffeine in that sense). Capsules are easy to dose; the empty stomach question is open but morning + breakfast is the safest default.
