L-arginine. What is it and what is doing?

01.06.2016

Arginine (abbreviated as Arg or R) encoded by the codons CGU, CGC, CGA, CGG, AGA, and is an α-amino acid that is used in the biosynthesis of proteins.
L-arginine is a chemical building block called “an amino acid.” It is obtained from the diet and is necessary for the body to make proteins. L-arginine is found in red meat, poultry, fish, and dairy products.

The effectiveness for L-ARGININE are as follows:

  • Chest pain (angina). Taking L-arginine seems to decrease symptoms and improve exercise tolerance and quality of life in people with angina.
  • Erectile dysfunction (ED). Taking 5 grams of L-arginine by mouth daily seems to improve sexual function in men with ED.
  • High blood pressure. There is evidence that taking L-arginine by mouth can reduce blood pressure in healthy people, people with high blood pressure, and people with slightly high blood pressure with or without diabetes.
    Inflammation of the digestive tract in premature infants. Adding L-arginine seems to prevent inflammation of the digestive tract in premature infants.
  • Nitrate tolerance. Taking 700 mg of L-arginine four times daily seems to prevent nitrate tolerance in people taking nitroglycerin for chest pain (angina pectoris).
  • Leg pain associated with poor blood flow (peripheral arterial disease). Research suggests that taking L-arginine by mouth or intravenously (by IV) for up to 8 weeks increases blood flow in people with peripheral arterial disease.
  • Improving recovery after surgery. Taking L-arginine before surgery or afterwards seems to help reduce the recovery time, reduce the number of infections.
  • High blood pressure during pregnancy (pre-eclampsia). Although there are inconsistent results about the effects of L-arginine on pre-eclampsia, most research suggests that it can reduce blood pressure in women with this condition.
