L-Ornithine HCL


L-Ornithine is a naturally occurring amino acid produced in the human body. It’s derived from arginine during critical biological processes, including the Krebs cycle, which is essential for energy production. Beyond its endogenous production, L-Ornithine can also be obtained through dietary supplements and various foods, enriching its availability for bodily functions.

Also Known As

L-Ornithine is known by several scientific names, which reflect its chemical structure:

  • Ornithine
  • (+)-(S)-2,5-Diaminovaleric acid
  • (+)-(S)-2,5-Diaminopentanoic acid


This amino acid is predominantly utilized in health and fitness supplements. Its ability to stimulate the production of human growth hormone (HGH) and insulin makes it popular among athletes and bodybuilders for muscle growth. L-Ornithine’s benefits extend to cardiovascular health, where it helps in regulating blood pressure and boosting nitric oxide levels. Additionally, it supports immune function, liver detoxification, and the removal of excess ammonia from the body.
