Another amino acid, L-citrulline, known as citrulline, has been researched for its potential benefits as a workout recovery supplement and to help boost immunity after exercise.
The vital nutrient called citrulline that relaxes the blood vessels is found in the highest concentration in the part you generally don't eat -- the watermelon rind.
"Watermelon has a phytonutrient called citrulline, and they've discovered that it can relax blood vessels and have a similar effect to Viagra," Reiley said.
However, watermelon is loaded with a nutrient called citrulline, which helps produce nitric oxide, a powerful blood vessel dilator that's critical to healthy blood flow.
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

Researchers at a university in Spain have found that citrulline can help preserve immune function after strenuous exercise.
"L-citrulline reduces time to exhaustion and insulin response to a graded exercise test."
