Did you know watermelon is a natural Viagra?
Watermelon is rich in an amino acid called citrulline, which relaxes and dilates blood vessels much like Viagra and other drugs meant to treat erectile dysfunction (ED).
Watermelon is a natural source of citrulline. Citrulline is an amino acid that may support better erections.
Viagra works by increasing blood flow to the penis, allowing a man to more easily get an erection when he is aroused. Citrulline may do the same thing, although it works in a different way to Viagra.
Research suggests that the body may convert citrulline to another amino acid, called arginine. Arginine converts to nitric oxide. Nitric oxide opens the blood vessels wider, increasing blood flow to the penis and improving erections.
Because watermelon is mostly water, the highest concentrations of citrulline come from concentrated watermelon juice.
