What is L-Citrulline?

L-citrulline is non-essential amino acid. Our kidneys change it into another amino acid called L-arginine and a chemical named nitric oxide. These compounds are important to heart and blood vessel health. 1

Key features:

  • Aids in maintenance of elasticity of blood vessels via increasing nitric oxide production (Nitric oxide is a molecule that relax the blood vessels resulting in increased oxygen and blood flow)
  • L-citrulline has been shown to be more effective in promoting the production of nitric oxide than L-arginine itself.

    • Cardiovascular conditions
    • Erectile dysfunction due to insufficiency of blood flow
    • Athletic support

L-Citrulline is an amino acid involved in both urea cycle and nitric oxide cycle. Though being the precursor of L-arginine, L-citrulline has been shown to be more effective in promoting the production of nitric oxide than L-arginine itself.
