Soy Protein Isolate (SPI) is a premium plant-based protein extracted from defatted soybeans, containing over 90% protein content. As a vegan alternative to whey protein, it’s widely used in health foods and sports nutrition due to its low-fat, zero-cholesterol profile and high digestibility.
Rich in essential amino acids (including BCAAs), SPI aids muscle synthesis, making it ideal for athletes and seniors combating muscle loss.
