Repleting lost NAD+ in the skin after UV exposure with the NAD+ precursors NMN and NR may present as an option for treating or preventing both the internal and external signs of skin aging.

Consuming just five prunes per day is sufficient to benefit a dozen or so risk factors related to cardiovascular disease, from reducing cholesterol to boosting antioxidant activity. 

A recent study found that combining supplemental NMN and melatonin protected the hearts of aging rats in several surprising ways. 

This work shows the importance of maintaining proper levels of NAD+ to stave off the senescence of blood vessel cells, which can be modulated with the NAD+ precursor, NMN.
