I was considering getting a treatment at a trichological clinic for hair fall. No need for it now, as I have been taking Primeadine for a couple of months now, and I can already experience the benefits. I have seen new hair growth and my scalp feels healthier. Also my eyelashes have grown longer, and my skin and nails look better, too. Thank you, Oxford Healthspan!

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!

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.

Thank you so much for sharing your experience, Jay!
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!

Thank you so much for sharing your experience! So pleased you're seeing such great results, you're very welcome!
I started taking Primeadine recently and had expected that it would take a while to experience any benefits, Instead, the Circadian reset was almost instant and I slept better than in years, waking up feeling rested and energetic. My husband has had a similar experience. I cannot recommend this wonderful supplement highly enough. Thank you, Leslie!

Thank you so much for sharing your experience, Emma! So pleased both you and your husband are experiencing the benefits already!
I'm very happy with spermidine. My most significant improvement is my bald spot is almost gone. This is in less than six months! I haven't experienced the sleep improvement but I already have healthy sleeping habits so no surprise there. I absolutely love the product and highly recommend it.
