A ‘Celiac diet’ is a gluten-free diet. Celiac disease is the name for an autoimmune disorder that is caused by a reaction to gluten – a protein found in wheat, barley, and rye.

The condition primarily affects that small intestine (the site of much of the absorption of nutrients in the body) resulting in inflammation and destruction of the villi (the ‘folds’ of the intestinal wall that increase the surface area, and therefore absorption of nutrients) of the intestinal wall. Symptoms can include chronic diarrhoea, bloating, loss of appetite, and malabsorption of nutrients, resulting in other health effects resulting from nutrient deficiencies.

The treatment of Celiac disease simply involves the complete removal of gluten-containing foods from the diet, and thus, a ‘celiac diet’ is one that is free from all wheat, rye, and barley.

Can Pea Protein be used in a Celiac’s diet?

Pea protein is free-from gluten and so, can be a great addition to the diet of someone with celiac disease. It is also practically free from other irritants (phytate, lectins, saponins, and trypsin inhibitors) and other potential allergens like soy, dairy, corn, and eggs. It provides a valuable protein ‘boost’ to the diet that is complete (contains all the essential amino acids) and compares very favourably with the recommended amino acid pattern proposed by the Institute of Medicine of the United States National Institutes of Health. (1) In fact, just one serving per day of Clean Lean Protein helps to provide around ¾ of your amino acid requirements for health. Pea protein isolates also have very high absorption rates (greater than 89%) (2) and this can be of benefit to those who have sustained damage to the gut and have potential absorption issues.

But does it get the job done?

In an evaluation of pea protein isolate vs. whey protein both types of protein resulted in nearly identical increases in muscle thickness when compared with placebo. (3) This demonstrates that pea protein is equal to whey protein for providing benefits to muscle tissue. In addition, pea protein is considered more satiating (it helps you to feel fuller and more satisfied for longer) and so offers tantalising benefits for helping to regulate eating and suggests benefits to weight and fat loss.

Why supplement with protein anyway?

Protein is made up of amino acids that are the ‘building blocks’ of nearly every cell and tissue in the human body, including muscles, organs, and chemical messengers, necessary for us to think, feel, and perform at our very best. So, protein intake to supply these amino acids is extremely important.
Key benefits of protein supplementation:

  • Improved lean body mass
  • Improved bone health
  • Increased satiety
  • Improved cardiovascular health


So, pea proteins like Clean Lean Protein provide an easy to digest, absorbable, protein boost that is completely compatible with a gluten-free diet for those with Celiac disease.
