If you’re looking for a natural remedy for mild erectile dysfunction, then L-citrulline is the answer. It may even increase male sexual desire.

L-citrulline is an amino acid that was first isolated from watermelon rinds. Years of studying this protein building block have led to some interesting findings.

In a recent study, men with mild erectile dysfunction received a placebo for 1 month and L-citrulline, 1.5 g/d, for another month. The erection hardness score, number of intercourses per month, treatment satisfaction, and adverse events were recorded. 

A total of 24 patients, mean age 57, finished the study without adverse events. An improvement in the erection hardness score occurred in 50% of the men taking L-citrulline and only 8% of the men when taking placebo. The average number of intercourses per month doubled in the treatment group. All patients reporting an erection hardness score improvement stated they were very satisfied. ⁽¹⁾

While L-citrulline may not be as effective as Viagra, supplementation is cheap, safe, and effective.

There are also cardiovascular effects of this supplement.

A study was done on 35 heart failure patients randomized into two groups: experimental group, with oral L-citrulline supplementation (3 g/day)and control group.

In the experimental group the left ventricular ejection fraction (LVEF) increased by 20%. In addition, heart failure symptoms markedly improved in 35%. ⁽²⁾ Another study found that a combination of the amino acids citrulline and arginine improve endothelial function and blood pressure in patients with congestive heart failure. ⁽³⁾

L-arginine is another amino acid used by many people looking for natural remedies to hypertension, erectile dysfunction, and angina. It is a vasodilator that opens up blood vessels but the problem is it’s broken down by the body when taken orally before it can really start working. In contrast, L-citrulline escapes this breakdown and is then converted to L-arginine.

L-citrulline is excellent for muscle recovery after exercise and may even enhance athletic performance. ⁽⁴⁾
