Protein Powder for Lupus

Is Protein Powder Good for Lupus Patients?

Lupus, also known as systemic lupus erythematosus (SLE), is a chronic autoimmune disease that can cause inflammation and pain in any part of your body.

When you have lupus, your immune system mistakenly attacks healthy tissues and organs, most often your skin, joints, kidneys, and heart.

Because lupus affects many parts of the body, it can cause many different symptoms, including fatigue, joint pain, and rashes.

Unfortunately, there is no cure for lupus, but treatments include certain medications and lifestyle changes.

Lupus patients do not have universally elevated protein needs.

That said, some individuals with lupus experience weight and muscle loss due to loss of appetite and complications such as protein-losing enteropathy.

If this is you, and you get enough protein from foods like eggs, fish, legumes, meat, nuts, and seeds, then adding protein powder to your diet might be a good idea.

Protein powder makes it easy to fill in gaps in your diet and ensure that you are meeting your protein needs.

That said, not all protein powders are created equal.

What Is the Best Protein Powder for People with Lupus?

The type of protein powder you use might not matter when it comes to lupus, but ingredients do matter.

Many protein powders contain ingredients that might contribute to the development and progression of lupus.

Among these potentially problematic ingredients are food additives and protein concentrates and isolates.

🚫 Avoid Food Additives

Regularly eating emulsifiers, thickeners, artificial sweeteners, and other additives can alter the composition and function of your gut microbiome (North Clin Istanb, 2019).

Over time, this can lead to gut dysbiosis, which has been linked to autoimmune conditions like lupus (Front Immunol, 2023; Nutrients, 2022).

Although more research is needed, there is evidence that gut dysbiosis can make autoimmune conditions worse via immune system confusion, leaky gut, and changes in gut metabolism byproducts (Int J Mol Sci, 2022).

⚠️ Here is a list of the most common food additives in protein supplements:

• acacia fiber
• acacia gum
• acesulfame potassium
• artificial flavors
• ascorbic acid
• aspartame
• calcium carbonate
• carrageenan
• cellulose gum
• dextrin
• dicalcium phosphate
• dipotassium phosphate
• erythritol
• gellan gum
• guar gum
• gum arabic
• inulin
• locust bean gum
• maltitol
• maltodextrin
• mono- and diglycerides
• ‘natural’ flavors
• rice bran extract
• rice dextrin
• rice hulls
• rosemary extract
• silica
• silicon dioxide
• sodium alginate
• soluble corn fiber
• sorbitol
• soy lecithin
• sucralose
• sunflower lecithin
• tocopherols
• tricalcium phosphate
• xanthan gum
• xylitol
• zinc oxide

As a rule of thumb, if you cannot find it in nature or make it at home, it is probably a food additive.

🚫 Avoid Protein Concentrates and Isolates

You might also want to avoid ultra-processed protein concentrates and isolates.

Most protein supplements are made from one or both of these ultra-processed protein sources, which have been mechanically and/or chemically stripped of everything but the protein.

This includes the enzymes, fiber, and other natural digestive aids that help your gut break them down.

You therefore do not digest them in the same way that you do whole foods, which could affect your gut health.

Studies show that regularly eating protein concentrates and isolates might disrupt your gut microbiome and cause the formation of toxic byproducts in your gut (Nutrients, 2018; Mol Nutr Food Res, 2024).

You should thus look for protein supplements made from whole food protein sources like egg whites and almonds, which are easier to digest and absorb.
