Ornithine

Definition

Ornithine is an amino acid that plays a role in the urea cycle, helping to remove excess nitrogen from the body.

Scientific / Technical Definition

Ornithine is a non-proteinogenic amino acid that acts as an intermediate in the urea cycle. It helps in the synthesis of urea from ammonia and is vital in the process of detoxifying ammonia in the liver.

Benefits

• Improves athletic performance by reducing fatigue.
• Enhances recovery by increasing the removal of ammonia during exercise.
• Supports liver health by participating in detoxification processes.

Examples

• Ornithine supplementation in pill or powder form.
• Foods like meat, fish, and dairy products that provide amino acids are indirectly related since ornithine is derived from these amino acids.

Additional Information

• Side effects: Potential side effects include gastrointestinal discomfort if consumed in large quantities.
