Primeadine improves sleep, nails and hair! I am 61 yo and have been taking 5 capsules of Primeadine for about 6 months. My Oura ring is tracking sleep scores in the 80s-90s, which I learned is super high for someone of my age range. My nails were dry and splitting, and now they are improved. My sparkling grays are reduced! Since there are no other changes in my life, I have to believe it is the Primeadine! Thank you for this great product!

Spermidine makes me feel good After using Spermidine along with NAD+, I have not only noticed increased daily energy, but also significant improved hair and nail quality. I’m very happy with it, and will definitely continue take it as long as I have the possibility.

My hairdresser cannot stop raving about… My hairdresser cannot stop raving about all my new hair growth. I've tried lots of different supplements for hair growth over the years - with no visible results. Finally, after using Primeadine for 6 months I can see a noticeable increase in hair thickness / fullness with lots of new baby hair sprouting out. I've even convinced my husband to start taking it!

Spermidine. I cannot express the difference in my general well-being since I added Spemidine to my daily kefir smoothie. My hair has grown, nails are stronger but the most significant change is the quality of my sleep. I sleep well and deeply. It’s incredible.
