Why Is There Lecithin in Protein Powder?

If you read ingredient lists, you have almost certainly come across lecithin.

Lecithin, to put it simply, is a group of fatty substances extracted from foods like soybeans and sunflower seeds.

It is one of the most common food additives because it is a cheap and powerful emulsifier; it allows you to mix things that do not normally mix well, like oil and water.

Putting lecithin in protein powder thus increases solubility, prevents separation, and improves texture and mouthfeel.

Note that if a label does not specify the type of lecithin, check to see if soy is listed as an allergen.

If it is, your protein powder probably contains soy lecithin.

Is Lecithin in Protein Powder Bad for You​?

Soy or sunflower lecithin in protein powder is something you want to avoid.

Although lecithin can naturally be found in many whole foods, the lecithin in protein powder is an ultra-processed derivative of food.

Here is a summary of the processing required to make lecithin from soybeans:

• Extraction: Oil is mechanically and/or chemically (using a solvent like hexane) extracted from the soybeans.
• Degumming: Water or a weak acid solution is used to extract the phospholipids (lecithin) from the oil.
• Centrifugation: A centrifuge is used to further separate the lecithin from the oil.
• Washing: The lecithin is washed with water or a dilute alcohol to remove impurities.
• Desliming: A centrifuge is used to remove any remaining impurities.
• Drying: The washed lecithin is dried under vacuum at low temperatures.
• Filtration: The dried lecithin is filtered before being processed into its final form (liquid, powder, granule, etc.).

Clearly, soy lecithin is not a whole food.

In fact, it is about as far from whole food as you can get, which is concerning.

Regularly consuming ultra-processed ingredients like lecithin might alter the composition of your gut microbiome – the collection of microorganisms living in your gut (Microbiome, 2021).

This, in turn, could lead to gut dysbiosis (an imbalance in gut bacteria), which has been linked to the development of a wide range of chronic diseases (Microorganisms, 2022; J Exp Med, 2019).

Because your gut microbiome affects various physiological processes, including immune function and inflammation, when the balance of bacteria therein is disrupted, it can have a huge impact on your overall health.

To be fair, lecithin is considered to be generally safe in typical dietary amounts, but little to no research has investigated the long-term effects of regular lecithin consumption in humans.

Given the mounting evidence linking ultra-processed ingredients to gut dysbiosis and therefore adverse health outcomes, it is safe to say that lecithin might not be something you want to put in your body on a regular basis.

What Is the Best Protein Powder Without Lecithin?

If you want to avoid lecithin, you probably also want to avoid other food additives.

🚫 Avoid Food Additives

As you just learned, regularly consuming emulsifiers, thickeners, preservatives, and other ultra-processed additives can cause painful side effects and even long-term health problems.

⚠️ Here is a list of the most common food additives in protein shakes and powders:

• 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

If you have a sensitive stomach, you might also want to avoid ultra-processed protein concentrates and isolates.

Most protein shakes and powders 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).

Individuals with pre-existing digestive issues should thus look for protein shakes and powders made from whole food protein sources like egg whites and almonds, which are easier to digest and absorb.
