L Citrulline increases L-Arginine formation. * Citulline is found in watermelon rind and to a lesser extent in watermelon flesh. L Citrulline, like arginine, is an important amino acid since it can convert into nitric oxide. Glutamine is a precursor of ornithine, which can be converted to citrulline by the intestine; citrulline is transformed in the kidneys to arginine. *

If you are buying citrulline for its arginine and nitric oxide effect and sexual improvement potential, consider instead, or in addition, Passion Rx which is extremely effective as an herbal sexual enhancer for men and women. * Passion Rx has a very high reorder rate. We have sample bottles of 8 capsules for $9.95. See Passion-Rx-Sample.

Does watermelon have effects similar to Viagra?
In July 2008 the media made a big deal of watermelon having Viagra-like effects since watermelon contains citrulline which converts into the amino acid arginine. Arginine helps dilate blood vessels. Because of this biochemical connection, Bhimu Patil, a researcher and director of Texas A&M's Fruit and Vegetable Improvement Center was quoted saying, "Arginine boosts nitric oxide, which relaxes blood vessels, the same basic effect that Viagra has, to treat erectile dysfunction and maybe even prevent it." Well, this is all the media needed to hype this story. But, does eating watermelon flesh or rind have any sexual enhancing effects? We have not noticed any Viagra-like effects from eating watermelon or drinking watermelon juice. Even if citrulline and arginine dilate blood vessels, their effects are brief. If you really want to enhance libido, sensation and sexual stamina, Passion Rx is one of your best options. *
