If ED continues to be a problem even after making certain lifestyle changes, talk with your doctor.

Doctors see patients every day about ED, so you’re simply one of millions of men dealing with this common condition.
1. Increased Blood Flow in Men with Lower Niacin Levels. Of course, there is a lot to an erection, but I think just about everyone would agree that the #1 goal is to increase something called endothelial function. The endothelium is the delicate lining of the arteries that pumps out nitric oxide and relaxes the arteries. And, of course, a relaxed, i.e. more open artery is one that allows more blood to flow into your arm, your leg or your brain. And I'm sure I don't need to explain why increased blood flow into your penile arteries is critical for erectile strength.
Supplements are popular and often cheaper than prescription drugs for ED. However, supplements have not been tested to see how well they work or if they are a safe treatment for ED. Patients should know that many over-the-counter drugs have been found on drug testing to have ‘bootlegged' PDE 5 Inhibitors as their main ingredient. The amounts of Viagra, Cialis, Levitra or Stendra that may be in these supplements is not under quality control and may differ from pill to pill. The FDA has issued consumer warnings and alerts.
Research has shown that the same eating patterns that can cause heart attacks due to restricted blood flow in the coronary arteries can also impede blood flow to and within the penis.

ED can be caused by a handful of things, but one thing’s for sure: You need a healthy supply of the neurotransmitter nitric oxide (NO) to get and maintain an erection. NO is produced in nerve tissue and helps jolt your Johnson by relaxing the smooth muscle so blood can fill the penis. After the initial release of NO, your body releases a cascade of chemicals—including more of the neurotransmitter—to help keep you hard and happy, according to a study in the Proceedings of the National Academy of Sciences.
According to the Centers for Disease Control and Prevention, ingesting levels of zinc in excess of the recommended dietary amount will result in diarrhea, vomiting, and stomach cramps.

If you have reason to suspect you have ingested too much zinc, contact a medical professional.
