Like metal specific amino acid complexes, Zinpro Corporation was the first company to manufacture metal amino acid complexes for animal diets. These complexes are manufactured with our patented “amino acid extraction process” that breaks down a pure source of protein into free amino acids. The free amino acids are then complexed to the trace mineral. The result is the most readily available form of trace minerals and a strong return on investment.
