Product Information



Cardiovascular Health
  • 100% Pure Powder
  • Promotes Nitric Oxide Production
  • Supports Vascular Blood Flow*

L-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, which in turn, can be used for the production of Nitric Oxide (NO). NO plays a fundamental role in vascular function and blood flow. Citrulline therefore, not only supports detoxification pathways, but also supports NO production and a healthy cardiovascular system.*

I will buy this product again!
I mix this in a pre-workout drink. I take another dose in the evening. It mixes very well and does not effect the taste. I have noticed no negatives so far.
