What is Brown Rice Protein?

Brown Rice Protein is derived from brown rice by isolating its protein content through processes like sprouting and fermentation followed by filtration. It is a popular plant-based protein option for those seeking alternatives to animal-derived proteins.

Brown Rice Protein is often used in protein supplements and meal replacements due to its relatively high protein content, which can support muscle building and repair. The evidence on its digestibility is mixed, with some studies suggesting it is less efficient than whey protein but can be complementary when combined with other plant proteins.

When you see it on a label, it typically indicates a plant-based protein source, suitable for vegans and those with dairy intolerance. However, its amino acid profile is not as complete as animal proteins, so it may be used in combination with other proteins to enhance nutritional value.

Commonly found in: protein powders, meal replacements, nutrition bars, smoothies, baked goods

Benefits

Provides a plant-based protein alternative for vegans and vegetarians.
May be easier to digest for people with lactose intolerance or milk allergies.

FDA

Brown rice protein is generally recognized as safe (GRAS) by the FDA as a food ingredient.

Research

Studies suggest it's less digestible than animal proteins but can be improved when combined with other plant proteins.

Vegan

It is a plant-based protein source, making it suitable for vegans.

Scout's take

Plant protein commonly paired with pea to round out the amino acid profile. On its own, brown rice protein is naturally low in lysine and less bioavailable than whey, so a larger gram dose is required to deliver the same usable amino acids for muscle protein synthesis. Brown rice is also the most well-documented arsenic accumulator in the food supply — the suspected source of arsenic detected here.

The case for

Provides a plant-based source of protein that is suitable for vegans and vegetarians.

More from Scout's analyses

Brown rice protein is a plant-based protein source that provides essential amino acids. It is organic, which indicates a higher quality and fewer contaminants. Compared to animal proteins, it may have a slightly lower bioavailability but is suitable for vegans.
