Introduction
L-Citrulline is a non-essential amino acid, meaning that our body is capable of producing it naturally. However, it can also be consumed as a dietary supplement for its many health benefits. In this article, we'll explore in detail the origins of L-Citrulline, its use as a dietary supplement and its scientifically proven benefits.
Origin of L-Citrulline
L-Citrulline was first discovered in 1930 in watermelons, hence its name, which comes from the Latin "citrullus" meaning watermelon. It is also present in other fruits such as melons, grapes and oranges. However, it is present in greater quantities in watermelon, which gives it its name.
In the human body, L-Citrulline is produced from another amino acid, L-arginine, which is converted into L-Citrulline by an enzyme called "argininosuccinate synthase". It can also be synthesised in a laboratory to make a dietary supplement.
Use as a food supplement
L-Citrulline is mainly used as a dietary supplement for its effects on health and its benefits for the body. It is often combined with other food supplements such as L-arginine or citrulline malate to potentiate its effects.
It is generally found in powder, tablet or capsule form. The recommended dosage is generally 3 to 6 grams a day, but it is always best to follow the manufacturer's recommendations or consult a healthcare professional for optimum use.
Benefits of L-Citrulline
L-Citrulline has a number of health benefits, which are supported by scientific studies.
Improving sporting performance : L-Citrulline is often used by athletes to increase endurance and reduce muscular fatigue. It increases the production of nitric oxide, a compound that dilates blood vessels and improves blood circulation. Better blood circulation allows the muscles to receive more oxygen and nutrients, improving performance and reducing fatigue.
Prevention of cardiovascular disease : The nitric oxide produced by L-Citrulline also has beneficial effects on the cardiovascular system. It helps to dilate blood vessels, reducing blood pressure and thus preventing cardiovascular disease.
Improving erectile dysfunction: L-Citrulline can also help improve erectile function in men with erectile dysfunction. The nitric oxide it produces dilates the blood vessels in the penis, making it easier to achieve an erection.
Strengthening the immune system : L-Citrulline also promotes the production of glutathione, an antioxidant that helps boost the immune system and combat the free radicals responsible for cell ageing.
Beneficial effects for the kidneys: L-Citrulline can benefit people suffering from kidney disease by helping to maintain normal kidney function. In fact, it increases the quantity of arginine and nitric oxide in the kidneys, which can help improve their function.
Conclusion
L-Citrulline is an amino acid with numerous health benefits. Its use as a dietary supplement is becoming increasingly popular, particularly among athletes, due to its effects on physical performance and general health. It is always advisable to consult a health professional before starting L-Citrulline supplementation, to ensure optimal, risk-free use.
