What vitamins help blood flow to the penis? im only 25 and my penis has shrunk 1 inch.

Let's find out: A young man's maximum flaccid length is unlikely to actually change, but many variables affect the quality of erection. If this is flagging even when things are very exciting, a physician can check you over for a host of illnesses (pituitary adenoma needs to be considered among many others). Forget about the vitamins.

Exercise: Vigorous exercise is a great way to improve penile blood flow and naturally boost testosterone. You can also add 2 grams daily of l-arginine, a natural amino acid, to increase Nitric Oxide levels.
