Rice protein

History of Ingredient

Rice protein is a high-quality, plant-based protein derived from brown rice. Rice protein extraction became popular in the early 21st century as demand for non-dairy and gluten-free protein sources surged. The protein is separated from the whole grain through a series of processes, including fermentation, filtration, and enzymatic treatment. 

This innovation marked a pivotal moment for vegetarians, vegans, and those with allergies to dairy or soy, providing a valuable alternative protein source.

Scientific Make-up

Rice protein is characterized by its unique amino acid profile. It contains all nine essential amino acids, making it a complete protein, albeit with lower lysine levels than other protein sources. 

Its bioavailability is often compared favourably to whey protein, although it has a distinct advantage for those with specific dietary restrictions. The protein content in rice protein supplements typically ranges from 80-90%, showcasing its dense nutritional value.

Benefits of Ingredient

Muscle Growth and Recovery

Rice protein supports muscle growth and recovery after exercise by supplying essential amino acids for protein synthesis. Studies have shown its effectiveness in promoting muscle hypertrophy and recovery rates comparable to whey protein.


Being hypoallergenic makes rice protein an excellent choice for individuals with allergies or sensitivities to dairy, soy, or gluten. Its natural composition ensures a lower risk of gastrointestinal distress or allergic reactions.

Weight Management

Including rice protein in your diet can aid in weight management. Its high-protein content can increase satiety, reducing overall calorie intake by keeping you feeling full longer.

Heart Health

Rice protein may contribute to heart health by potentially lowering blood cholesterol levels. Its plant-based origin is naturally low in cholesterol and saturated fats, supporting cardiovascular well-being.

Versatility in Diets

This protein supports various dietary needs, from vegan to gluten-free, making it a versatile ingredient in different nutritional regimens.

Forms of Consumption

Rice protein is available in several forms, catering to different preferences and dietary requirements:

  • Powder: Ideal for shakes and smoothies, offering a convenient protein boost. 
  • Tablets: A portable option for those on the go. Explore tablet manufacturing options.
  • Capsules: Capsulated forms are perfect for precise dosage without taste. 
  • Liquid Gels: Liquid gel capsules provide an alternative for quick absorption. Find out about liquid gel manufacturing.

Safety + Dosages

Rice protein is considered safe for most individuals when consumed as a balanced diet. The recommended daily intake varies depending on body weight, activity level, and individual health goals. 

Generally, a dosage of 1.2 to 2.0 grams of protein per kilogram of body weight is suggested for active individuals. It’s always advisable to consult with a healthcare provider to determine the appropriate dosage for your specific needs.

Use and Legality in UK, EU, US, and Globally

Rice protein is legal and widely used in dietary supplements and food products across the UK, EU, US, and globally. Regulatory bodies such as the FDA in the United States, EFSA in the European Union, and the FSA in the UK have deemed rice protein safe for consumption. Manufacturers and brands must adhere to strict quality and labelling standards to ensure consumer safety.
