## Overview

NOW Foods Sports Nutrition Arginine & Citrulline Powder delivers a scientifically balanced 1:1 amino acid blend designed to support muscle tissue maintenance, protein metabolism, and ammonia detoxification. With GMP-certified purity and 113 servings per container, this unflavored powder is ideal for athletes and professionals seeking enhanced energy, focus, and recovery in a clean, allergen-free formula.

## Description

Arginine and Citrulline are two amino acids that are integral to protein metabolism and utilization, as well as to the maintenance of muscle tissue.* Both are key intermediates in the urea cycle, where they participate in the detoxification of ammonia via the production of urea.* In addition, any arginine not converted to urea enters general circulation where it is distributed to various tissues and metabolized for other uses such as protein synthesis.* Natural color variation may occur in this product.

Review: Works great - but nasty fish after taste - Wow these have a kick!! I feel it in my brain moments after taking one dose. It has a terrible after taste of fish though. Something I wish I’d have known up front. I can’t swallow large pills so I needed the powder. I don’t take two scoops a day, just one; but it works! I feel the energy and muscle recovery these give. Also helps my focus and alertness. Definitely worth the nasty fish taste. 🤢
Review: Arginine &Citrulline powder is bitter but tolerable if mixed with right ingredients - This product is very bitter (due to its alkalinity)- so let me tell you how I make it taste tolerable. Mix whatever amount of Arginine you prefer-(I use a blender) in cold- add blueberry juice (not from concentrate-0 added sugar), tart cherry juice (not from concentrate-0 added sugars), fresh ginger root (chop one small piece from peeled root), sunflower lecithin powder (optional), and honey (I use manuka honey, but any honey would work)- blend together - if you want you can add extra above ingredients to taste. I am able to drink like a regular beverage, and I find that most of the bitter taste is masked.

### ⭐⭐⭐⭐ Works but tastes very bad
*by D***E on June 2, 2025*

I feel the product does work. However the taste needs to be improved. It tastes like how a cow pasture smells. Fruit juices do help.
