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.
