Ornithine

Individuals engaged in high-intensity physical training might benefit from testing their ornithine levels, as it’s involved in the urea cycle and helps reduce ammonia in the body, which can be beneficial for athletic performance. Those with liver conditions or disorders affecting the urea cycle, as well as individuals on high-protein diets or those experiencing fatigue and sleep disturbances, could also find such testing useful.

• Fatigue and low energy
• Poor sleep quality
• Muscle weakness
• Confusion or brain fog due to elevated ammonia levels
• Digestive issues

Ornithine is not typically obtained directly from foods, as it is primarily produced in the body from arginine. However, consuming arginine-rich foods like meat, fish, poultry, eggs, and dairy can indirectly support ornithine levels. Plant-based sources of arginine, such as nuts, seeds, and legumes, also contribute to ornithine production.

Ornithine supplementation can enhance the body’s ability to dispose of excess nitrogen and reduce fatigue, especially after exercise. It may improve sleep quality and aid in muscle recovery. Ornithine also supports liver function and can be beneficial for individuals engaging in intense physical activity or those with liver health concerns.
