HealthWise® L-Ornithine is 100% pure pharmaceutical grade amino acid powder. L-Ornithine is an amino acid actively involved in producing urea and helps facilitate the removal of nitrogen and ammonia from the body, thereby balancing the body pH. L-Ornithine is also well known for its role in muscle repair and works in tandem with L-Arginine to achieve this. Did you know? Ornithine is the amino acid favoured for use in parasite cleansing programs as it detoxifies ammonia and nitrogen through the kidneys by stimulating urea production.
