What’s NMN?
NMN stands for nicotinamide mononucleotide, a organic molecule present in all species. Around the molecular level, it’s a ribonucleotide, a simple structural unit with the nucleic acid RNA. It has a nicotinamide group, a ribose, plus a phosphate group.

NMN is really a precursor of nicotinamide adenine dinucleotide (NAD+), a molecule that may be beneficial in reducing some elements of aging. NAD+ serves many critical functions in our cells, for example electron transport, cell signaling, and DNA repair.

Accumulating evidence points too as we age, our amounts of NAD+ decline, increasing our chance of age-related diseases.

This is how the NAD+ precursor NMN will come in. Some researchers believe if we can restore that lost NAD+, we might not simply slow aging but also delay various age-related diseases. If restoring NAD+ metabolism in humans will slow aging or support healthy longevity remains an unanswered question, although animal details are promising.

What foods contain NMN?
NMN is found naturally in foods including avocado, broccoli, cabbage, cucumber, and edamame. Here is how much NMN can be found in some common foods.

While most of these foods are an excellent source of nutrition, dietary NMN supplements can also be found. These supplements typically come in doses which can be between 100 – 500 mg, although an ideal dose has not yet been determined in people.

Fasting and caloric restriction also appear to increase NAD+ levels and raise the activity of sirtuins, aka the longevity genes. It is strongly recommended that their activity utilizes the presence of NAD+. In mice, fasting boosted NAD+ levels and sirtuin activity, plus it appears to be slow down aging.
