What exactly is NMN?
NMN stands for nicotinamide mononucleotide, a naturally sourced molecule present in all species. On the molecular level, it is just a ribonucleotide, an elementary structural unit in the nucleic acid RNA. It includes a nicotinamide group, a ribose, along with a phosphate group.

NMN can be a precursor of nicotinamide adenine dinucleotide (NAD+), a molecule which may be attractive slowing down some aspects of aging. NAD+ serves many critical functions inside our cells, including electron transport, cell signaling, and DNA repair.

Accumulating evidence shows that as we grow older, our levels of NAD+ decline, increasing our likelihood of age-related diseases.

That’s where the NAD+ precursor NMN comes in. Some researchers believe that when we can restore that lost NAD+, we might not simply decelerate aging and also delay various age-related diseases. Whether or not restoring NAD+ metabolism in humans will decrease aging or support healthy longevity remains an unanswered question, though the animal details are promising.

What foods contain NMN?
NMN can be found naturally in foods such as avocado, broccoli, cabbage, cucumber, and edamame. This is one way much NMN can be found in some common foods.

While these types of foods are loaded with nutrition, dietary NMN supplements are also available. These supplements typically can be found in doses which is between 100 – 500 mg, although an ideal dose has not yet been determined in people.

Fasting and caloric restriction also may actually increase NAD+ levels and boost the activity of sirtuins, aka the longevity genes. It is suggested that the activity utilizes the use of NAD+. In mice, fasting boosted NAD+ levels and sirtuin activity, also it appears to be slow down aging.
