Nicotinamide Mononucleotide (NMN) is a supplement that promotes vitality, energy and helps with the nervous system. It is a precursor to nicotinamide adenine dinucleotide (NAD). Niacin is a form of vitamin B3. NAD plays a critical role in maintaining the health of your brain, heart, and other organs.

The level of NAD in your body declines as you get older. This decrease in NAD can lead to fatigue and muscle weakness. Taking a NMN supplement may help to replenish NAD+ levels, which are essential for the normal functioning of the mitochondria.

NMN is the precursor to NAD+, and can be found naturally in your body. But as you age, NMN levels decline, and a NMN supplement may be useful.

NMN may be able to balance stress caused by free radical damage and inflammatory processes, and may even improve cellular health. Nicotinamide mononucleotide has shown promising effects in animal models. NMN is safe and well tolerated in humans.

Some studies have shown that NMN supplementation has therapeutic effects for age-induced complications. For example, NMN may increase the production of insulin in people with metabolic syndrome who are on a high-fat diet. Other studies show that NMN may lower oxidative DNA damage and improve behavioural dysfunctions.

Several studies have shown that NMN can help increase the abundance of beneficial bacteria in your gut microbiome, while decreasing the amount of harmful populations. Researchers believe that a healthy and diverse microbiome is important for aging, and a NMN supplement can help to maintain it.
