About Brown Rice

Brown rice protein is a plant-based protein isolate or concentrate derived from whole grain brown rice (Oryza sativa). It is produced by removing the carbohydrate and fiber components, resulting in a powder typically containing 70-90% protein. It is considered a complete protein as it contains all nine essential amino acids, though it is relatively low in lysine compared to animal proteins. It is hypoallergenic, gluten-free, easily digestible, and a popular vegan alternative to whey or soy protein. The protein fraction is rich in the amino acid arginine and contains bioactive peptides with potential health benefits.
