L-CITRULLINE is a naturally occurring amino acid the body makes on its own. L-Citrulline can also be obtained through dietary foods as well as outside supplementation. The body changes L-citrulline into another amino acid called L-arginine and also to nitric oxide. L-citrulline may help increase the supply of ingredients the body needs to make certain proteins. It might also help open up veins and arteries to improve blood flow and reduce blood pressure. L-Citrulline is predominantly used to increase energy, improve athletic performance, reduce muscle weakness and help eliminate fatigue. Studies have also shown that added citrulline increases the amount of arginine in the blood leading to increased nitric oxide production which translates to longer workouts, less soreness after strenuous activity and better recovery.
Evidence suggests the supplement could possibly help lower blood pressure in people with prehypertension. This is an early warning sign for high blood pressure. It means you have a slightly raised blood pressure reading of 120/80 to 139/89. Prehypertension raises your risk for high blood pressure and heart disease.
L-citrulline supplements may ease symptoms of mild-to-moderate erectile dysfunction (ED). Scientists say L-citrulline does not work as well as ED drugs such as Viagra. However, it appears to be a safe option.
Animal studies suggest L-citrulline might also help people with blood vessel problems such as slow wound healing due to diabetes.
Other animal research says L-citrulline might improve muscle protein levels and prevent malnourishment in the elderly.
The animal research also suggests L-citrulline may help treat intestinal problems, including:
Short bowel syndrome
Radiation-caused small bowel damage
Certain genetic disorders and health conditions such as liver disease may be helped by L-citrulline supplements.
Early human studies done also hint that L-citrulline may be helpful for Parkinson’s disease and certain dementias.
The only difference between L-citrulline and citrulline malate (CM) is the addition of malic acid. That may seem like a minor detail, but it can have a significant impact on your performance.
Malate serves as an important component in the tricarboxylic (or TCA) cycle, which is one way your body produces energy. When you increase malate levels, you increase energy production. Therefore, citrulline malate provides the one-two punch of bringing additional blood—and subsequently, oxygen and nutrients—to exercising muscles, as well as providing increased energy to boost performance levels.
