Give men with erection problems 250 mg daily of propionyl-L-carnitine [structural formula shown below] together with 2500 mg L-arginine and their sex life will improve. Researchers at the Sapienza University of Rome discovered this when they did experiments with 54 men aged between 35 and 75.
Most of the test subjects indicated that they would like to continue using the supplement. Few side effects were observed.
"In addition to first-line treatment in selected patients, the formulation tested may have a role as adjuvant therapy", the researchers conclude.
