One of the most overlooked signs of good metabolic health is muscle mass. Those with more muscle live longer. It’s one of the strongest predictors of longevity. Muscle is a metabolic organ. If you have good muscle growth in the body, you have good mitochondria numbers too.
A new study looked at NR and its effects on NAD+ and muscle mitochondria. 24 sets of twins were included in the study, both men and women around 40 years of age. They were given increasing doses of NR from 250mg-1000mg over the course of a 5-month study. This is one of the longest studies conducted on NR.
They discovered that participants saw an average 230% increase in NAD+ levels. This rise fuels NAD+ Benefits throughout the body. Moreover, muscle samples showed an increased number of muscle stem cells and more mitochondria.
It turns out that NR and its boost in NAD+ may also be a significant factor in the promotion of mitochondria in muscle. In doing so it may promote muscle mass and add another mechanism to its support for longer lifespan.
