Can You Take Ornithine with Threonine?

The available scientific evidence does not suggest any significant interaction between ornithine and threonine. This means that taking them together does not seem to cause any notable effects, either positive or negative. As a result, no special precautions are needed when combining these supplements. The available evidence does not suggest a direct biochemical interaction between ornithine and threonine. Ornithine is involved in the urea cycle and arginine biosynthesis, while threonine is an amino acid important for protein synthesis. The regulation of carbamoylphosphate synthetase, an enzyme in the pyrimidine nucleotides and arginine biosynthetic pathways, is activated by ornithine, but there is no indication that threonine affects this process directly.
