Vitamin B3, or niacin -- found in chicken, fish, and grains -- may help men overcome erectile dysfunction (ED) if they have high cholesterol, according to a new study published in the Journal of Sexual Medicine.

The results, published earlier this month, show that the 80 men in the study with moderate or severe erectile dysfunction (ED) and high cholesterol reported an improvement in their ability to maintain an erection after supplementing their diet with niacin. The 80 men who took a placebo pill, who also began the study with only mild ED, did not experience a change in their symptoms, the researchers said.
