Amino Acid

  • Conditionally Essential Amino Acid

Other Ingredients

Gelatin (capsule), magnesium stearate (vegetable source) and silica.

Not manufactured with wheat, gluten, soy, milk, egg, fish, shellfish or tree nut ingredients. Produced in a GMP facility that processes other ingredients containing these allergens.

The L-Arginine used in this product is Pharmaceutical Grade.
