Rice protein is extracted from rice and used in some protein supplements. Vegetarians may prefer it over protein supplements made from animal sources (such as whey or casein, which are milk proteins). Since rice is rarely involved in food allergies,1 rice protein may also be preferred by people with food allergies, and may be suitable to use in hypoallergenic infant formulas.2 Rice protein is not a complete protein, however, due to insufficient levels of the amino acids lysine and threonine.3, 4 Therefore, these amino acids are often added to rice protein products to correct this imbalance.

  • Reliable and relatively consistent scientific data showing a substantial health benefit.
  • Contradictory, insufficient, or preliminary studies suggesting a health benefit or minimal health benefit.
  • For an herb, supported by traditional use but minimal or no scientific evidence. For a supplement, little scientific support.

Our proprietary "Star-Rating" system was developed to help you easily understand the amount of scientific support behind each supplement in relation to a specific health condition. While there is no way to predict whether a vitamin, mineral, or herb will successfully treat or prevent associated health conditions, our unique ratings tell you how well these supplements are understood by the medical community, and whether studies have found them to be effective for other people.

For over a decade, our team has combed through thousands of research articles published in reputable journals. To help you make educated decisions, and to better understand controversial or confusing supplements, our medical experts have digested the science into these three easy-to-follow ratings. We hope this provides you with a helpful resource to make informed decisions towards your health and well-being.
