Product Overview


  • Supports Protein Metabolism
  • Healthy Immune System Function
  • GMP Quality Assured
  • A Dietary Supplement

Citrulline is a non-essential amino acid that is an important intermediate in the urea cycle, functioning along with Arginine and Ornithine to rid the body of ammonia, a byproduct of protein metabolism. Because Citrulline is a precursor of Arginine, it provides a readily available source material for Arginine production, thereby helping the body maintain healthy Arginine levels. Citrulline also plays an important role in the healing process and in the maintenance of a healthy immune system.

Suggested Use

As a dietary supplement, take 1 to 2 capsules 1 to 2 times daily between meals. Consider taking this product in combination with NOW L-Arginine, P-5-P and AAKG.

Other Ingredients

Gelatin (capsule), calcium carbonate, magnesium oxide and magnesium stearate (vegetable source).

Contains no sugar, salt, yeast, wheat, gluten, soy, milk, egg, shellfish or preservatives.

I am very disapointed with iherb. I never receive my order. I think this web page is a scam... The order was paid by paypal, but until today i never received, so I can't give a review about this product

Didn't notice any effects

Posted by 5343655630868221025 on Jun 05, 2016

I was really hoping this supplement would help improve my Raynaud's symptoms, but I noticed zero improvement. I started off taking one capsule twice a day and increased this to two capsules twice a day. Early evidence suggests that taking 500 to 1,000 mg of L-citrulline twice a day when Raynaud's symptoms begin could increase the amount of nitric oxide in the hands and toes, which increases blood vessel size and blood circulation. L-arginine, which has a similar effect, requires double the dose. I don't believe any clinical trials of L-citrulline have been undertaken yet.
