Nicotinamide ribose (NR), a derivative of vitamin B3, is a precursor substrate of nogar factor nicotinamide adenine dinucleotide (NAD+). It can increase NAD+ levels after ingestion. It is white or light yellow crystalline powder, odorless, bitter in taste, slightly hygroscopic.
Nicotinamide riboside (NR), a derivative of vitamin B3, acts as a driving substance for nicotinamide adenine dinucleotide (NAD+). Nicotinamide ribose was discovered in 2004 as a vitamin precursor for NAD+ and in 2007 (Charles Brenner) as a Sirtuin-activating compound. Sirtuins have also been implicated in regulating DNA health and longevity in many organisms.
Nicotinamide ribose is converted by the body into nicotinamide adenine dinucleotide (NAD+), a coenzyme or accessory molecule. NAD+ acts as a fuel for many key biological processes, and NAD+ levels in the body naturally decline with age. Lower NAD+ levels have caused health problems such as aging and chronic diseases such as diabetes, heart disease, Alzheimer's disease and vision loss. Studies have found that boosting NAD+ levels may help reverse signs of aging and reduce the risk of many chronic diseases. Nicotinamide riboside supplementation has rapidly gained popularity because it is particularly effective at increasing NAD+ levels.
Summarize: Nicotinamide riboside, or niacin, is another form of vitamin B3. It's recommended as an anti-aging supplement because it boosts your body's levels of NAD+, which fuels many key biological processes.
Nicotinamide riboside is available in tablet or capsule form, and a daily dose of 250-300 mg of nicotinamide riboside is recommended.
