Can NMN Keep Our Blood Vessels Young?

Ever wondered why our bodies struggle to grow new blood vessels as we age? The blame often goes to endothelial cells, which line our blood vessels and have a hard time copying themselves and producing energy. The root cause? They're missing a vital molecule called NAD+.Intriguingly, scientists found that when they gave aging mice a supplement called nicotinamide mononucleotide (NMN), which boosts NAD+, the mice's blood vessels improved, and their energy levels increased. This hints at a potential breakthrough in maintaining healthy blood vessels as we age. However, before we get too excited, it's crucial to note that these findings are just the beginning. More research is needed to fully understand how NMN benefits humans. So, while NMN shows promise, we should stay cautious and curious.
