Aerobic and resistance exercise training reverses age-dependent decline in NAD + salvage capacity in human skeletal muscle: https://pubmed.ncbi.nlm.nih.gov/31207144/
NR and NMN are popular ways to try to boost levels of NAD+, but that approach hasn’t worked every time in human studies. One reason for that may involve CD38, which degrades both NR and NMN. With the goal of boosting NAD+ levels during aging, why does CD38 increase with age, and what can be done about it? All that and more in this video!
