Key points from article :
Researchers from the University of Washington reviewed ten recent NMN clinical trials and summarised their findings.
NMN was well tolerated in all ten trials, with no serious adverse effects reported.
Some studies showed that NMN supplementation can improve physical performance and muscle function in older adults.
Other studies showed that it can improve insulin sensitivity and blood sugar control in people with pre-diabetes.
It was also linked to increased oxygen and energy consumption, suggesting potential athletic performance improvement.
However, the trials were small and short-term, so more research is needed to confirm NMN's safety and long-term effects.
