DHEA is effective with low levels of testosterone due to age. Study shows that intake of proper amounts of DHEA significantly improves both erectile function and sexual desire in men.
L-arginine increases the production of nitric oxide. Nitric oxide relaxes or dilates blood vessels, enabling them to open up and bring more blood to the penis and helping to create an erection.
