about this product.

Tru Niagen is a nicotinamide riboside (NR) supplement from ChromaDex, the company that holds the foundational patents on NR as a distinct form of vitamin B3. NR is a precursor to NAD+, a coenzyme involved in cellular energy metabolism, DNA repair, and the activity of sirtuins — proteins studied for their role in healthy ageing. NAD+ levels decline naturally with age, and supplementing with a precursor such as NR is one of the more researched strategies for supporting those levels.

This formulation delivers 300 mg of nicotinamide riboside per capsule. It suits people who want to address age-related cellular decline, those in demanding physical or cognitive routines, and anyone whose clinician has flagged NAD+ support as relevant to their health picture. It is not a quick-fix; consistent daily use over weeks is how most people approach it.

ChromaDex uses a patented form of NR called Niagen, which has been the subject of peer-reviewed human studies examining its ability to raise blood NAD+ levels. The ingredient has a more substantial evidence base than many NAD+ precursors on the market, which is a meaningful distinction in a category full of loosely substantiated products. For those serious about cellular health and longevity science, this is one of the more credible starting points.

frequently asked.

What is nicotinamide riboside and how does it differ from niacin?

Nicotinamide riboside (NR) is a form of vitamin B3, as is niacin. The key difference is the pathway each takes to raise NAD+ levels. NR converts to NAD+ via a distinct enzymatic route and, unlike high-dose niacin, is not associated with the skin flushing that many people find uncomfortable.

How long before I notice any difference?

NAD+ precursors tend to work gradually at the cellular level rather than producing noticeable day-one effects. Most human studies run for several weeks. It is reasonable to commit to daily use for four to eight weeks before drawing conclusions, and some people track progress alongside a blood panel.

Can I take this alongside other supplements or medications?

NR is generally well tolerated, but if you are on any prescription medication — particularly those affecting liver metabolism — it is worth checking with your GP or clinician before adding it. As with any supplement, do not exceed the recommended dose without professional guidance.

Is this suitable for vegetarians or vegans?

Check the packaging for full excipient and capsule details, as we cannot confirm the shell composition from the information available here.

Does taking more than one capsule increase the benefit?

Some individuals take higher amounts under clinical guidance, but the established daily dose for this product is one capsule. Do not adjust the dose without speaking to a clinician — more is not automatically better, and the evidence base is built around studied amounts.

QQVerified Buyer

The first adrenal support that made a quick difference.

4 days ago

Gentle on a sensitive stomach, and I feel like myself again. I had tried two other glandulars before this and neither sat right.

MRVerified Buyer

Steadier mornings within a fortnight.

1 week ago

I was sceptical about glandulars, but my mid-afternoon crash has genuinely eased. One capsule with breakfast and I forget about it.

ALVerified Buyer

Subtle, but real.

2 weeks ago

Not a stimulant, which is exactly what I wanted. It took about ten days, then I realised I wasn’t dreading the afternoon any more.

SKVerified Buyer

My clinician recommended it.

3 weeks ago

Bought after a blood panel flagged a flat cortisol curve. Easy to take, no jitters, and the sourcing is refreshingly transparent.

TPVerified Buyer

Recovery feels faster.

1 month ago

Training hard through a stressful stretch and this has helped me bounce back between sessions. Already on my second bottle.

DVVerified Buyer

Does what it says.

1 month ago

No frills, one ingredient, a sensible dose. I appreciate that it is designed to be used for a season rather than forever.
