Tru Niagen - 300 mg

Tru Niagen® is powered by a patented form of nicotinamide riboside called Niagen®, a clinically proven NAD+ precursor. This unique formulation is the result of decades of pioneering research in cellular health. Unlike standard supplements, Tru Niagen® delivers a highly bioavailable form of vitamin B3 that efficiently raises NAD+ levels—an essential molecule for energy production and cellular repair. Each batch undergoes over 20 rigorous tests to ensure safety, potency, and purity, and all manufacturing is carried out in ISO/IEC 17025:2017 accredited laboratories. With transparent practices and strict quality control, Tru Niagen® offers science-backed support for healthy ageing at the cellular level.

Founded in 1999 under the name ChromaDex, Niagen Bioscience began with a bold mission: to bring cutting-edge scientific discoveries to everyday health. Through close partnerships with world-renowned universities and institutions, the company developed Niagen®, the most researched NAD+ precursor available. Tru Niagen® emerged as the flagship product, now trusted worldwide and backed by two Nobel Prize winners, over 35 human clinical studies, and 400+ published scientific papers. What started as a vision for innovation has grown into a global leader in healthy-ageing science—setting the gold standard in safety, quality, and transparency.

Tru Niagen is meant to be taken daily to support increased NAD+ levels. If you're a new user, we recommend starting with 300mg/day, which is clinically proven to increase NAD+ levels by up to 50% in as soon as two weeks, and allow your cells to establish a new baseline NAD+ level with continued supplementation over the course of about eight weeks. Please note that everyone's experience will be different, and is greatly dependent on your overall health and other factors. Depending on how you feel taking 300mg, you can start taking more Tru Niagen to further increase NAD+. Tru Niagen is safe to consume up to 2,000mg/day.
