Men hoping for some fireworks in their love life this Fourth of July may want to skip the burgers and beer at the barbecue and eat plenty of...instead.
It turns out, watermelon may be a natural Viagra, says a researcher. That's because the popular summer fruit is richer than experts believed in an amino acid called citrulline, which relaxes and dilates blood vessels much like Viagra and other drugs meant to treat erectile dysfunction (ED).
Until recently, many scientists thought most of the citrulline was in the watermelon rind. But now, experts have discovered that there is more citrulline in the edible part than previously believed.
Why does this work?
The amino acid citrulline is converted into the amino acid arginine. This is a precursor for nitric oxide, and the nitric oxide, a blood vessel relaxer that enhances circulation to all your vital parts.
How much watermelon should you eat?
A typical 4-ounce serving of watermelon (about 10 watermelon balls) has about 150 milligrams of citrulline.
The class of drugs that Levitra, Viagra, Stendra, and Cialis belong to are called PDE5 inhibitors. They work by relaxing tight blood vessels, allowing more blood to surge into the penis and cause an erection, says Gregory Bales, M.D., an associate professor of urology at the University of Chicago.
The little pills do the trick for more than two-thirds of men with Viagra protects the heart (ED). They also work for guys who simply need them for a short time to get their “confidence back,” says Michael Eisenberg, M.D., director of male reproductive medicine and surgery at Stanford University.
