Product Overview

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 cleansing pathways, but also supports NO production and a healthy cardiovascular system.*

I had been using another brand of L-Citrulline powder but decided to try Doctor's Best based on the other reviews. So far, I have been very disappointed. The powder does not dissolve well in water. Despite vigorous stirring for much longer than with the other brand, the powder still does not dissolve. I am left with a glass of water with a pile of sediment at the bottom of the glass. I am trying to return the unopened product and would not buy it again.

Mixes well with my pre/intra workout drink. Produces unbelievable vascularity and pump during my workouts. Even the veins in my chest and shoulder make an appearance during my workouts. Plus I know that with the increased vascularity and blood flow, my muscles will benefit greatly and grow from this. Love this product!

I stack this with my intra-workout drink. It gives me an excellent pump, I'm talking about vein popping results right away during my weight training sessions. Works exactly as intended. Highly recommended. It is unflavored but mixes well in a shaker bottle with other supplements.
