What is arginine and ornithine?

Arginine and ornithine are amino acids that play a significant role in increasing growth hormone levels. Arginine is known for its effects on blood vessel dilation, which helps improve blood flow. It can be consumed through food, supplements, or intravenously. Taking arginine has been observed to increase growth hormone levels substantially, typically by 400-600% above baseline. Dosages can range from 3 grams to over 9 grams, but higher doses may cause gastrointestinal disturbances and potentially blunt the hormone release.

Ornithine works in conjunction with arginine to enhance the production of growth hormone. Both of these amino acids are often used together in supplements aimed at boosting growth hormone levels for various health and performance benefits 1.
