Tru Niagen review

If you are going to take an NAD⁺ precursor, Niagen is the most defensible thing to take: it is the NR ingredient with the most published human trial data and the clearest regulatory paper trail, and it sidesteps the regulatory question that has followed NMN. That is a real advantage over unbranded precursors — but it buys you a well-evidenced biomarker change, not a proven benefit to how you age.

Tru Niagen is the consumer supplement brand of Niagen Bioscience, formerly ChromaDex. It sells Niagen, the company's patented form of nicotinamide riboside, as oral capsules at 150 mg, 300 mg and a 1,000 mg Pro daily serving, as 300 mg powder stick packs, and in bundles with immune and beauty formulas, on a subscription or one-off basis. It is a dietary supplement sold over the counter — there is no clinician, no prescription and no clinical service attached to it. The core NR products sit beside Beauty and Immune blends and skincare; a single-ingredient description applies to the selected core product, not every brand extension.

Direct-to-consumer retail with a subscription option; you order online and it ships. Nobody reviews your health history, so dosing and any interaction questions are yours to take to your own physician. The upside of the model is that the ingredient itself is the same one used in published trials, so if you want to match a studied dose you can do it precisely — NR trials cluster around 300–1,000 mg/day.

The 300 mg, 30-capsule pack lists $49 one-time or $39.20 every month by subscription. Larger subscription packs list $101.60 every three months or $195.20 every six months; those totals are not monthly charges. Savings labels and a table headed Monthly Cost are inconsistent with some pack arithmetic, so confirm the selected debit. Returns must be within 30 days of purchase with the original seal and factory condition; opened products are excluded. Confirm return-shipping costs because policy passages differ.

None — a dietary supplement, not a medication. What genuinely distinguishes Niagen is its documentation: the NR chloride ingredient has been through the FDA's new-dietary-ingredient notification process twice without objection and has an FDA no-objection response to its GRAS notification, and it is the NR form used in the published human work — including a controlled study establishing that oral NR is bioavailable and raises the blood NAD⁺ metabolome dose-dependently, and a randomized placebo-controlled trial in healthy middle-aged and older adults finding chronic NR well-tolerated and effective at elevating NAD⁺. That is a real safety and bioavailability package, and it is more than almost anything else in this category has. It is also exactly where the evidence stops. In that randomized trial the cardiovascular signals were exploratory and suggestive, not confirmed endpoints, and no trial of NR shows it extends healthspan, prevents disease or slows aging. As an NR product it is not affected by the regulatory dispute that has surrounded NMN.
