Soy protein isolate is a highly purified protein source extracted from soybeans. It undergoes a more intensive processing method than soy protein concentrate to remove even more carbohydrates and anti-nutritional factors, resulting in a product with a protein content typically exceeding 90%. 
This exceptional protein content makes soy protein isolate a premier source of essential amino acids, including Lysine, which is often limiting in other feed ingredients. Additionally, it contains essential minerals like phosphorus, supporting bone health and growth. 
Soy protein isolate is an ideal choice for formulating high-performance diets fo poultry, swine, other livestock, and even humans. Particularly when a concentrated and easily digestible protein source is required.
