The Importance of NMN and NAD+ in Aging and Health

Scientists have long been fascinated by the role of NMN in the body’s production of NAD+, a crucial coenzyme involved in various biological processes. NMN, a naturally-occurring molecule, is a precursor of NAD+ and plays a key role in maintaining cellular health and function.

According to experts like registered dietitian Kathryn Piper, NAD+ is essential for converting food into energy for our cells, as well as for repairing DNA and preventing cell damage. However, as we age, NAD+ levels tend to decline, leading to potential health issues such as metabolic disorders, mental disorders, and neurodegenerative diseases.

While NMN can be found in small amounts in certain foods like broccoli, avocados, and cucumbers, supplementation may be necessary for individuals who need higher levels of NMN. Aging can further exacerbate the decline in NAD+ levels, affecting tissue function and cellular health.

Fortunately, there are natural ways to boost NAD+ levels, particularly for older adults. Registered dietitian Mary Sabat suggests that physical activity can stimulate the production of NAMPT, an enzyme involved in NAD+ synthesis. By increasing NAMPT activity through exercise, individuals may be able to elevate their NAD+ levels and counteract some of the age-related decline.

Research supports the benefits of exercise in increasing NAD+ levels, with a 2019 study showing positive effects on older adults’ NAD+ levels after 12 weeks of aerobic and resistance exercise. These findings highlight the importance of maintaining adequate NAD+ levels for overall health and well-being, especially as we age.
