The benefits of NMN supplementation have been studied extensively in animal models, and there is growing interest in its potential benefits for humans. One of the key benefits of NMN is its ability to increase NAD+ levels in the body. NAD+ levels decline as we age, and this has been linked to a range of age-related health issues, including a decline in cognitive function, decreased energy levels, and an increased risk of chronic diseases such as cancer, diabetes, and heart disease. By increasing NAD+ levels, NMN may help to counteract some of these effects of aging.
