Info: 60 Veg. Capsules

NOW L-Ornithine is an amino acid that's been used by athletes and fitness enthusiasts for years, because metabolizing protein during exercise produces high levels of ammonia, which can impair muscle function and cause fatigue. Other causes of high blood ammonia levels besides exercise can include poor kidney or liver function, whether due to diseases like hepatitis, enzymatic problems, or various kinds of drugs (including some prescription drugs and alcohol). Ornithine functions with Arginine and Citrulline in the urea cycle, to rid the body of ammonia. And because Ornithine also gets converted into Arginine or into other amino acids such as citrulline, proline, glutamate, or creatine, it can also help maintain healthy levels of those in the body and serve as a muscular energy source.
