Overview
What Is Arginine Ornithine Powder?
Exercising regularly promotes whole body health and longevity. But muscle soreness can make it difficult to maintain an exercise routine. That’s where Arginine Ornithine Powder comes in. These amino acids have both been shown to support muscle mass, health and recovery after exercise—and have other potent whole-body health benefits as well.
Arginine and ornithine are protein-building amino acids that promote muscle strength and recovery after exercise.
Arginine Ornithine Powder Benefits
- Provides support for healthy muscle recovery
- Helps promote muscle mass
- Encourages a healthy immune response with arginine
- Promotes healthy endothelial function
- Supports already-healthy blood pressure levels

What is L-arginine?
L-arginine is an amino acid involved in ammonia detoxification, hormone secretion and immune modulation, and is a precursor to nitric oxide (NO).

Why did we add L-ornithine?
L-ornithine is an amino acid that the body uses to build healthy muscle tissue and bone. L-ornithine also encourages the release of growth hormone.
Many Functions, One Amino Acid
Arginine plays many different roles in keeping you healthy. As a semi-essential amino acid, arginine is involved in immune and endothelial function. It helps your body produce nitric oxide, which supports vascular relaxation and healthy circulation, helping to maintain already-healthy blood pressure levels.

Product Details
Arginine and ornithine have been shown to help promote muscle mass and strength and support healthy body composition in exercising adults.1-3 But that’s not all these two amino acids can do.
L-arginine
Arginine is a semi-essential amino acid known for its role in the production of nitric oxide (NO). Arginine is converted to nitric oxide by your immune cells and the endothelial cells that line your blood vessels. Because of this, arginine promotes vascular relaxation, helps maintain already-healthy blood pressure levels and promotes a healthy immune response.4,5
L-ornithine
This is a non-essential amino acid that the body actually makes out of arginine. Our cells use ornithine to produce proline, which is needed for collagen formation, as well as nitrogen-based compounds called polyamines that help support gene expression and promote healthy cell growth, division and survival.6-8
Both arginine and ornithine help your cells convert ammonia, an unwanted byproduct of protein metabolism (such as after exercise), into urea, a compound that can be safely excreted via the kidneys.

Reviews
I have been very happy taking this supplement.
I find it really helps me and I have been using the powder form for about 5 years, Very simple to take and it desolves easily in any liquid. And it doesn't have a taste so it blends easily. Worth while for my Joints and also good for my skin.
Love it!
Best product ever! Back in the day you could only get small amounts in capsule form-this powder blows that away!
Great product
An excellent product and I like the Powder because it is one less pill to swallow. Great for the Joints.
First found out about this product in the 70's. Amazed @ the dosage. Only 60 mg/arginine in the 70's and 40mg ornithine sold separately in pill form. 2 teaspoons sufficed for me
