L-arginine is an amino acid that contributes to the production of nitric oxide and keratin. These in turn help to dilate blood vessels and facilitate blood circulation. Nitric oxide helps to reduce the tension in the walls of blood vessels.
L-arginine is involved in the production of nitric oxide. Nitric oxide helps lower blood pressure, improve blood supply, increase oxygen permeability and prevent cardiovascular disease. As a result, L-arginine helps keep heart function and blood circulation regulated and normal. In addition, L-arginine helps to release a number of hormones. It also speeds up wound healing.
The use of L-arginine is common among athletes who want to increase muscle growth in the body. In addition, L-arginine is used to lower blood pressure, preeclampsia and increase sexual performance in men.
L-arginine is also needed to help release glucagon, insulin and growth hormones. It also helps remove ammonia from the body.
Symptoms associated with an overdose of L-arginine include nausea, diarrhea, and abdominal pain. Overdose can also cause bloating, headaches, allergic reactions and inflammation in the airways. Asthma symptoms may also worsen.
