What is L-Arginine?

L-Arginine is one of the critical amino acids required by our body. The body uses this conditionally essential or semi-essential amino acid in protein synthesis, the urea cycle, and tissue repair. L-Arginine gets converted to nitric oxide and citrulline, which act as vasodilators. 

Additionally, it acts as a precursor to amino acids like glutamic acid, proline, and creatine and is required for the smooth functioning of our immune system. L-Arginine is necessary for developing T-cells, which are white blood cells that play central roles in an immune response. 

Although our body can produce Arginine, external supply may become essential during some conditions like pregnancy, intense exercise, infancy, trauma, and critical illness. Meat, nuts, poultry, fish, lentils, peanuts, pumpkin seeds, dairy, and soy products are a few L-Arginine foods. It can also be obtained by taking L-Arginine supplements widely available in capsules, powder, liquids, and tablets. 

L-Arginine: Benefits & Uses

L-Arginine offers a wide range of health benefits, such as:

  1. Boost exercise performance: L-Arginine has been shown to increase exercise performance by improving blood flow and elevating the supply of oxygen and nutrients to the muscles.
  2. Enhance endurance: L-Arginine increases the level of nitric oxide in the body by promoting the production of creatine. The combined effects of increased oxygen delivery to the muscles and high energy levels due to creatine help boost endurance. 
  3. Promote muscle pump: The improved blood circulation and enhanced supply of oxygen to the muscles increase the pump effect and make your muscles look stronger and more athletic.
  4. Support muscle recovery: L-Arginine is a precursor to many amino acids like ornithine that helps remove nitrogenous waste from the body. This amino acid also helps support recovery by reducing lactic acid accumulation and delaying muscle fatigue. 
  5. Promote healthy blood sugar levels: Studies say that L-Arginine may benefit people with diabetes by improving insulin sensitivity and glucose metabolism.
