NAM (nicotinamide) is a type of vitamin B3 analog. It can help raise your NAD levels.

However, it can also cause adverse side effects. For example, it can lead to pellagra, which causes diarrhea. And it can have ill effects on beta-cells in the pancreas.

In addition to increasing NAD+, NMN may have protective effects on various body processes. For instance, it might reduce the risk of heart disease. Also, it may increase insulin sensitivity. Some studies suggest that NMN can also improve the quality of sleep.

NMN supplementation can also increase lean mass in mice. But more research is needed to determine whether it actually has anti-aging effects in humans.

Currently, NMN is being investigated in numerous clinical trials. The doses used in these trials range from oral supplements to injectable forms.

Despite its potential for anti-aging benefits, NMN has not yet been approved by the FDA. That could change in the future. Until then, it is advisable to check with a health consultant before taking any supplements.

NMN has shown some protective effects on the skin. In fact, it can help reduce sun damage. This is due to its ability to lower the amount of melanin in the skin.

NMN can also enhance your immune system. A study found that NMN supplementation can increase the activity of the immune system. Additionally, it can help slow senescence, a process that contributes to aging.

As we age, our bodies produce less and less NAD+. Therefore, NMN is a promising supplement for people who are experiencing age-related weight gain.
