I would like to share an article / video from the Harvard Medical School this time.
Treatment restores blood vessel growth, muscle vitality, boosts exercise endurance in aging animals

“As we grow old, we become weak and frail. A constellation of physiological changes—some subtle, some dramatic—precipitate this inevitable decline. ”
One of these changes is muscle loss
“The process can be slowed down with regular exercise, but gradually even exercise becomes less effective at holding off this weakening.”
When Harvard Medical School published the above research results in March 2018, all experiments were done in animals. However, human trials were available since then. Here is one of such human trials.

Also, there are a lot of user testimonies. Here’s one of them.
This 70+ gentleman could only do 20 pushups before taking NMN. He was able to do 40 pushups after.
NMN also improved his sleep and joints.
