The 10 Best L-Arginine Supplements for 2022

L-arginine is an essential amino acid used by the body to:

  • produce proteins
  • maintain the urea cycle
  • repair tissue

L-arginine conversion produces nitric oxide and citrulline, which are vasodilators.

The immune system depends on L-arginine as a precursor to amino acids like glutamic acid, proline, and creatine. It helps mature essential T cells.

  • While the body can produce arginine in certain circumstances, external sources may be needed.
  • Foods like dairy, soy products, meat, almonds, chicken, fish, lentils, peanuts, and pumpkin seeds contain L-arginine.
  • L-arginine supplements are widely available in capsules, powder, liquids, and pill forms.
