Rice Protein: Organic, plant-based protein powder

Derived from 100% organic brown rice, our Rice Protein Powder is a natural source of plant based protein that’s shown to benefit muscle growth, improve exercise recovery, support fat loss and benefit general health.

Here are five key benefits of our Rice Protein…

  • Naturally sugar free
  • Contains 100% organic brown rice protein
  • Ideal for lean muscle development
  • Packed with vital amino acids
  • Low in carbs

Rice Protein encourages muscle growth and faster recovery

Bulk Nutrients’ Organic Brown Rice Protein Powder offers a great spread of amino acids compared to other vegan friendly plant based protein powders on the market.

In fact, Rice Protein is a complete protein as it contains all the essential amino acids required by the body from food. This is also very beneficial for muscle development.

A 2013 study found that Rice Protein consumption post workout improved body composition and exercise performance in just the same way as whey protein does. This makes it a top choice in post workout nutrition.

Rice Protein Isolate is gentle on the digestive system

For those who suffer from bloating or stomach discomfort from creamy dairy proteins, Rice Protein is a dream. Its hypo-allergenic and contains none of the allergens typically found in whey, soy or egg proteins.

What’s even better? It’s so easy on the digestive system. Being a highly bio-available protein, our Rice Protein Isolate is easily digested by the body.

Add Rice Protein your smoothie for a protein boost

Rice Protein makes the perfect addition to your morning smoothie, mixed into oats or baked into clean treats for ad extra boost of natural plant based protein.

What could be better than a serve of Vanilla Brown Rice Protein Powder every morning in your smoothie, we’re sure it will quickly become your go to daily protein option.

The ultimate veggie protein blend starts with RPI

Rice Protein is commonly blended with Pea Protein to produce a powder with a balanced spectrum of amino acids.

While Rice Protein is high in the sulfur-containing amino acids, cysteine and methionine, but low in lysine, Pea Protein is low in cysteine and methionine but high in lysine, so they’re a perfect match when combined!

Together Rice and Pea proteins offer a superior amino acid profile that is comparable to dairy or egg proteins, but without the potential for allergies or intestinal issues that some users have with those proteins.

What’s more, the light, fluffy texture of Pea Protein Isolate tends to smooth out the strong, chalky flavour of the Rice Protein.

Keen to give it a try? Check out Earth Protein, our premium Pea and Rice blend.

About Rice Protein Isolate

Rice Protein is an organic, lightly refined protein source made using brown rice. It’s low in fats and carbohydrates and has high levels of protein, alanine, arginine, glutamic acid and tyrosine. The amino acid spectrum is also considered broad for a plant-based protein.

Rice Protein Isolate is completely free of soy, dairy or lactose, which reduces side effects and promotes gentler digestion.

Rice Protein FAQs

How is Rice Protein made?

Rice Protein is made using a water extraction process, separating the carbs from the rice and leaving behind the protein content.

Why is Rice Protein a good protein?

Rice Protein is a good protein as it contains more than 85% protein with low levels of both fats and carbohydrates.

It contains all 9 essential amino acids and is close to an ideal “complete” protein. It is slightly low in Lysine, which prevents it being labelled complete by traditional standards.

Is Rice Protein good for building muscle?

Yes, while its bioavailability score of 90% is slightly lower than whey (100%) some studies as recently as 2018 suggested it builds muscle as well as whey. For a plant based protein source, it contains high amounts of L Leucine – a key amino for muscle growth. Rice Protein is absorbed slightly more slowly than whey which makes it ideal between meals.

Is Rice Protein lactose free?

Yes, Rice Protein is lactose free.

How much fat does Rice Protein contain?

Rice Protein contains around 4% fat, so is lower in fat than Pea Protein but higher than Whey Isolate.

Does Rice Protein contain cholesterol?

No, Rice Protein is cholesterol free as it is a plant protein.

Does Rice Protein contain gluten?

Rice Protein naturally contains no gluten, but we do process other ingredients in our facility that contain gluten.

How does Rice Protein taste?

Flavoured Rice Proteins are said to have an average taste.

Does Rice Protein have a strange texture?

Texture is rice protein's greatest weakness. It is best described as gritty and can be chalky. These textural issues have been resolved with a higher mesh protein, many companies now using finer powders which reduce this side effect.
