This product works as advertised. Just a teeny 1/8 spoon size dose gives me the boost of energy in the morning. At 72, it’s something I’ve needed to get me going! Mixes in very well with my yogurt.
Both nmn and resveratrol I believe are excellent products . I am looking for 1 gram sized products .
My skin feels and looks smoother. Nails seem to be growing faster and are stronger. I haven't been taking it long enough to say I notice a big improvement in my hair .... but I do notice it's not falling out as much. No tummy issues, but I do take it at night.
Excellent product! Vital for anyone who takes health & longevity seriously!
