What is L-Arginine/L-Ornithine?

The Ls are essential amino acids, meaning that they are components which cannot be produced by the body and, therefore, must be obtained from a diet or through supplementation.

L-Arginine is a conditionally essential basic amino acid involved primarily in urea metabolism and excretion as well as DNA synthesis.

Studies have shown:
Improved immune responses to bacteria.
Viruses & tumor cells.
Promotes wound healing and regeneration of the liver.
Causes the release of growth hormones.
Considered crucial for optimal muscle growth and tissue repair.

Arginine is an "essential" amino acid in infants, in the elderly, and in people undergoing stress. The human body can convert arginine into nitric oxide, which "opens up" circulation, or into L-ornithine, which is used in creating new tissues. In cancer treatment, arginine supplementation is part of a strategy of giving cancer cells the amino acids they "don't want" while depriving them of amino acids they need to proliferate. The important consideration, however, is that different kinds of cancer cells have different metabolic requirements.

is an amino acid that has been used by fitness enthusiasts for years. L-Ornithine is a non-essential amino acid and is manufactured by the body. Since the body can produce ornithine, a deficiency of this non-essential amino acid is rare and it is abundant in protein foods such as meat, fish, dairy, and eggs.

L-Ornithine is necessary for proper immune-system and liver functions. It plays an important role in detoxifying ammonia and in aiding liver generation. L-Ornithine helps promote the release of growth hormone, which helps promoting metabolism of excess body fat.

Ornithine is important since it:
Induces the release of growth hormone in the body, which in turn helps with fat metabolism Required for a properly functioning immune system and liver. Assists in ammonia detoxification and liver Rejuvenation. Helps healing and repairing skin and tissue and is found in both these body parts.

Unsupported claims that ornithine promotes muscle building, but this has not been proven. Helpful for people recouping after surgery and athletes may benefit from this nutrient.
