L-arginine is an essential amino acid. L-ornithine may be used as an alternative since it metabolizes to L-arginine in the body. L-arginine is required for the body to synthesize nitric oxide, which enables the arterial system to retain its youthful elasticity. Nitric oxide also helps to produce endothelial relaxation factor, which is needed by the arterial system to expand and contract with each heartbeat.
L-arginine and L-ornithine have been shown to promote natural growth hormone (GH) release from the pituitary gland. GH promotes healthy anabolic metabolism throughout the body, helping to maintain protein synthesis within cells.
Surgical or traumatic injury greatly increases the body's need for L-arginine, a key building block to repair damaged tissue and bone. Because of it's role in repair of tissues, L-arginine helps to promote optimal healing of wounds. L-ornithine may also be used for this purpose.

Dosage and Use
L-arginine and L-ornithine are most effectively utilized when taken on an empty stomach with water or juice. To maintain the natural release of growth hormone, 6-12 grams of pure L-arginine or half as much pure L-ornithine or a proportional combination of both are suggested for healthy male adults before exercise or sleep depending on the weight of the individual. For healthy female nonpregnant, nonlactating adults, half that amount is suggested. For more details on GH releaser suggestions by weight and sex, see the Growth Hormone Releasing Formulas in the Hormones Section of this catalog.
L-arginine free base powder can be mixed with water or juice, however it is alkaline and some people find that mixing ascorbic acid with it produces a more pH neutral and palatable drink. The HCL product naturally produces a pH neutral and more palatable drink when mixed with water or juice.
Start with about 25% of your target quantity and increase it gradually over a period of a few days to minimize the occurrence of minor side effects such as nausea. Naturally occurring growth hormone release is improved if 1-3 grams of choline and 1/2-2 grams of pantothenic acid are taken at the same time as amino acid releasers. The product, Choline Chloride Liquid, contains both choline and pantothenic acid and is appropriate for this purpose.
Take four capsules on an empty stomach at bedtime, or as directed by a health professional.
Caution
Diabetics and borderline diabetics should use growth hormone releasers with care. L-arginine and L-ornithine might improve or worsen a diabetic condition.
Persons who have not completed their bone growth (children and teenagers) and pregnant or lactating women should not use GH releasers except under a physician's supervision.
L-arginine and L-ornithine sometimes reactivate latent herpes virus infections. Therefore, persons who have had ocular or brain herpes should not use them.
Those with certain psychoses may experience worsened symptoms if they take L-arginine or L-ornithine supplements.
Always take antioxidants with arginine.
Higher amounts can be taken if recommended by a knowledgeable healthcare professional.
