Citrulline is a dietary supplement that helps to relieve stress and increase energy levels. It is classified as a non-essential amino acid, and it may be found in certain foods. Citrulline may also be referred to as L-citrulline or alpha amino gamma ureidovaleric acid. It can be found as an ingredient in many health supplements and may also be taken separately in tablet form.
The supplement's name was derived from the Latin meaning for watermelon. It may be found in various food sources such as red meat, fish and some diary products. It is also present in fruits and vegetables such as watermelons and onions. This amino acid was first discovered in 1960 and has since been proven to delay muscle fatigue and also provide more energy during an exercise training program.
Citrulline also promotes the formation of nitric oxide, a component that supports blood flow and overall system health. Nitric oxide also supports a healthy immune system and promotes vasodilation. Many bodybuilders favor the increased vasodilation benefits, thus making this amino acid a popular supplement choice for many athletes.
The supplement also removes toxic elements from the body. It helps to rid the liver of ammonia, a component which may become toxic to the system in large amounts. Citrulline thus acts as an effective detoxification agent for the body. It is a natural amino acid that can be taken by any individual or athlete.
Many men may also choose to take this amino acid to assist with sexual dysfunction. Since this is an all-natural product with little or no side effects, it is considered a safe alternative for men. It also helps to promote the optimal functioning of the urea cycle in the body. This, in turn, also ensures that toxins are removed from the body effectively.
The recommended dosage for citrulline is about three grams per day. It may be taken with food as well to increase its absorption into the body. Although this amino acid is generally considered safe, it is not recommended for consumption by children under the age of 12.
There have been no reports of negative side effects of this supplement. Individuals with a history of liver problems are advised to first consult with their physicians before taking citrulline.
