Nicotinamide riboside (sold as Niagen and Niacel) is a form of vitamin B3 (niacin) that has been promoted as having anti-aging effects, such as increasing energy, improving cognitive function, and improving cholesterol levels -- without causing flushing. However, the evidence for these uses appears to be very preliminary, as discussed in the "Niacin" section of the B Vitamin Supplements Review.
Nicotinamide riboside can raise NAD+ levels in the body, and this is the scientific basis for some of its effects. However, there is theoretical concern that compounds that raise NAD+ levels could also stimulate the growth of existing cancers.
Like supplements containing Niagen and Niacel, the supplement Basis(Elysium Health) includes 250 mg of nicotinamide riboside per recommended daily serving (typically two capsules) but also contains 50 mg of pterostilbene. Details about our laboratory tests of Basis and a clinical study investigating the effects of this supplement can be found, respectively, in the "What CL Found" and "Niacin" sections of the B Vitamin Supplements Review >>
