Can protein powder be used by people with an autoimmune disease?

People with autoimmune diseases can use protein powder, but it is crucial to choose the right type based on individual health conditions and dietary needs. Protein powders can be a beneficial supplement for those needing extra protein due to dietary restrictions or increased needs associated with managing their condition.

However, certain protein powders may contain ingredients that could potentially trigger inflammation or immune responses in individuals with autoimmune conditions. For instance, whey and casein proteins are derived from dairy, which some people with autoimmune diseases may need to avoid if they have sensitivities or allergies to dairy products. Similarly, soy protein can be problematic for those with thyroid issues, a common concern in autoimmune conditions like Hashimoto's thyroiditis1.

Plant-based proteins, such as pea, rice, or hemp protein, are often recommended as they are less likely to cause allergic reactions or inflammation. These proteins are typically easier to digest and free from common allergens2. It's also beneficial to choose protein powders that are free from added sugars, artificial flavors, and preservatives, which can contribute to inflammation.

It is important for individuals with autoimmune diseases to consult with a healthcare provider or a dietitian before starting any new supplement regimen. This is crucial to ensure that the protein powder does not interfere with their overall diet plan or medication regimen and is safe for their specific health condition3.
