Product Description Manganese amino acid chelate is an organic compound of manganese commonly used as a nutritional supplement and plant growth regulator. Its source is usually formed by chelating manganese ions with amino acids. The active ingredients of manganese amino acid chelate are manganese ions and amino acids. Manganese is an important trace element that plays an important role in the growth and development of plants and animals. Amino acids are important organic molecules in living organisms and can be used as nutrients for plants and animals.
