Yes, Niagen (NR) is generally considered safe. In the first study conducted by Chromadex to clinically evaluate NR IV, acute intravenous infusions of 500 mg NR were safe in the study participants with no attributable adverse events and only minor and transient infusion-related experiences.
Once NR is converted into NAD+, NAD+ plays a vital role in various cellular processes, including improved energy production, DNA repair, cellular health, metabolism and cognition.
Niagen is a powerful, patented, pharmaceutical-grade form of NR (nicotinamide riboside), and it’s the most efficient and superior precursor to nicotinamide adenine dinucleotide (NAD+) available on the market.
