Sperm motility: Vitamin E, selenium, CoQ10, L-Carnitine, and DHA have been documented to increase the ability of the sperm cells to swim
DNA quality: Studies have shown that antioxidants has the ability to reduce the number of molecules called ‘free radicals’. These free radicals damage cells throughout the body.
