About this supplement

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.

Physical properties

Fine, off-white to light tan powder. Typically odorless with a mild, neutral flavor. Soluble or dispersible in water, depending on processing (isolates are more soluble). Hydrolyzed forms have improved solubility.

How it’s made

Produced through a series of milling, enzymatic treatment, and filtration steps. Brown rice is treated with enzymes (e.g., amylases) to break down and remove starch. The resulting slurry is centrifuged and filtered to separate carbohydrates. The protein-rich liquid is then concentrated via ultrafiltration and spray-dried to create a powder. Some processes use a fermentation step to improve digestibility and flavor.
