  • Helps build muscle
  • Improves sexual function in both men and women
  • Improves antioxidant defence
  • Plays a role in correct glucose metabolism

L-Arginine is an amino acid that has many functions in the body. It is best known for being a precursor to nitric oxide in the endothelium (innermost layer of the arteries), which allows the blood vessels to relax and open up, thus improving blood flow and oxygen transport throughout the body, helping to normalise blood pressure - when blood pressure is high it can severely damage arteries and blood vessels.

 L- Arginine may also help wounds to heal faster, improve sexual function (in individuals with low nitric oxide [NO]), help build muscle, and increase immune system function.

Arginine is a standard amino acid that can be synthesised in the body from ornithine (a non-proteinogenic amino acid). Many bodybuilders take arginine to help increase muscle mass and decrease body fat.

Arginine also plays an important role in correct glucose metabolism.


Most amino acids come in two forms; D- or L- (such as L-tyrosine or D-tyrosine). D-amino acid is a mirror image of the L- amino acid - in other words the D- form is a backward image. Both can be taken. However, the L- form is preferable as it is the exact image of the amino acid in its natural form found in the body. The L- form is considered more effective for overall human health.


As a dietary supplement, adults take one capsule, two to six times daily between meals, or as directed by a health professional.

Store in a cool, dry place, away from direct light.

Do not exceed the recommended daily dose.

Keep out of reach of young children.

Nutritional supplements should not replace a varied and balanced diet and a healthy lifestyle.

Check with simultaneous intake of medicines with your physician or healthcare professional. No long-term use without professional advice.


May increase the outbreak of herpes simplex infections (cold sores or genital herpes). The addition of Lysine, an amino acid, can limit this effect. It may cause nausea and diarrhoea.
