Key item features

  • Supports overall muscle health— The semi-essential amino acid l-arginine and the amino acid l-ornithine have been shown to support aspects of muscle health, especially after exercise. They benefit muscle mass, strength and recovery.
  • Encourage a healthy immune response— Among L-arginine’s many roles, it is involved in immune modulation. Because of this, it helps support optimal immune health and function.
  • Promotes already-healthy blood pressure—Arginine and ornithine are also involved in healthy endothelial and nitric oxide production, key to supporting healthy vascular relaxation and promoting already healthy blood pressure. 
  • Ingredients matter – We use only pure, high-quality ingredients. The majority of our products are non-GMO and gluten-free—and a Certificate of Analysis is available for every one.
  • Live your healthiest life - For over 40 years, we’ve been developing advanced, effective formulas made with the highest standards and based on the latest scientific findings. We believe the answers to a healthier, richer life are within reach, and that rigorous scientific research is the path to get us there. That’s why so many of our nutritional formulas are designed using specific ingredients and amounts based on scientific studies.

This stuff Works!

This is exactly what is stated. It is best taken before bed in my opinion and you will see results quickly. also take 1 to 3 grams a night or a big teaspoon.
