Amino Acids—Ornithine, Arginine and Citrulline
The Tri-Amino nutrient injection combines three clinically researched amino acids—ornithine, arginine and citrulline. All three of these amino acids are involved in the urea cycle and also key contributors to nitric oxide production.
Ornithine is distinct from arginine and citrulline as it is not involved with nitric oxide production, but ornithine buffers ammonia, reducing fatigue associated with exercise. When your cells break down nitrogen-containing compounds, such as proteins, they produce ammonia as a byproduct and can be toxic if not removed.
Ornithine is called a nonessential amino acid because your body can manufacture it. As part of the urea cycle, your liver cells produce ornithine from the amino acid arginine, which you consume in many different foods. Dietary sources of ornithine include meat, fish, eggs and dairy products, and especially good sources of arginine include turkey, peanuts, soybeans, egg whites and sesame seeds. Some studies suggest that taking ornithine prior to consuming alcohol may reduce hangovers, due to alcohol increasing ammonia levels. This may be particular to those with decreased liver function or those with alcohol sensitivity.
