A human study also found that NMN supplementation improved cerebral blood flow, which could have implications for cognitive function.

These findings suggest that NMN supplementation could potentially be used to improve cognitive function in individuals with age-related cognitive decline or neurological disorders.

3. Anti-Aging Effects

One of the most promising benefits of NMN supplementation is its potential anti-aging effects. NAD+ plays a crucial role in DNA repair and cellular functioning, and increasing NAD+ levels through NMN supplementation could help combat age-related cellular decline.

A study conducted on mice found that NMN supplementation improved several age-related health markers, including muscle function and glucose tolerance.

Another study found that NMN supplementation increased the lifespan of mice on a high-fat diet.

While more research is needed to determine the anti-aging effects of NMN supplementation in humans, these findings are promising and suggest that NMN supplementation could be a valuable tool in the fight against age-related decline.

4. Cardiovascular Health

NMN supplementation has also been linked to improved cardiovascular health. A study conducted on mice found that NMN supplementation improved endothelial function, which can help reduce the risk of cardiovascular disease.

Another study conducted on human subjects found that NMN supplementation improved arterial stiffness, a risk factor for cardiovascular disease.

These findings suggest that NMN supplementation could potentially be used to improve cardiovascular health and reduce the risk of cardiovascular disease.

5. Metabolic Health and Weight Management

NMN supplementation has also been linked to improved metabolic health and weight management. A study conducted on obese mice found that NMN supplementation improved glucose tolerance and insulin sensitivity.

Another study conducted on human subjects found that NMN supplementation improved muscle insulin sensitivity and lipid metabolism.

These findings suggest that NMN supplementation could potentially be used to improve metabolic health and aid in weight management.

In addition to its potential health benefits, NMN supplementation is generally considered safe and well-tolerated, with no significant adverse effects reported in human studies.

Overall, while more research is needed to determine the full extent of its potential benefits, NMN supplementation shows promising potential as a tool for improving energy levels, cognitive function, cardiovascular health, metabolic health, and potentially even as an anti-aging intervention.
