Brown rice protein makes an excellent option for those with dairy, soy and/or gluten allergies as well as for vegetarians and vegans. Brown rice protein is a great alternative that offers a variety of health and fitness benefits, including muscle recovery and fat burning. Since brown rice is not a complete protein, you can pair it with other plant-based proteins like hemp or pea powder in order to complete the essential amino acid profile, making it more comparable to dairy or egg proteins.
