Emulsifier-Free Protein Powder​

Why Are There Emulsifiers in Protein Powder?

An emulsifier allows you to mix things that do not normally mix well, like oil and water.

Adding emulsifiers to protein powder thus increases solubility, prevents separation, and improves texture and mouthfeel.

Common emulsifiers found in protein powders include:

• lecithin (soy or sunflower)
• gum (guar, xanthan, etc.)
• carrageenan
• mono- and diglycerides

Note that if the ingredient 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.

Are Emulsifiers Bad for You?

In the United States, emulsifiers and other food additives are approved for human consumption by the U.S. Food and Drug Administration (FDA), which suggests they are safe.

But many of these same additives are banned or restricted in other parts of the world, such as the European Union, due to links to health concerns.

For example, more and more research suggests regularly consuming certain emulsifiers can cause side effects and even long-term health problems (Nat Rev Gastroenterol Hepatol, 2024).

This is probably because emulsifiers are ultra-processed foods.

For this reason, they can be hard to break down and absorb, especially if you have pre-existing gut issues.

This can cause painful side effects like bloating and diarrhea.

It can alter the composition and function of your gut microbiome (North Clin Istanb, 2020).

These shifts, known as gut dysbiosis, have been shown to contribute to chronic diseases like obesity, type 2 diabetes, and even certain cancers (Biomolecules, 2019).

It is worth noting that some emulsifiers are marketed as healthy.

A good example of this is lecithin, which is a group of fatty substances found in foods like soybeans and sunflower seeds.

In its natural form, lecithin can support brain, liver, and heart health, help with digestion, reduce inflammation, and maintain healthy skin.

But the lecithin in protein powder is an ultra-processed ingredient extracted from whole foods by extensive mechanical and chemical processing.

This does not necessarily make it bad for you, but given what we know about the relationship between food processing and human health, it is concerning (BMJ, 2024).

What Is the Best Emulsifier-Free Protein Powder?

If you are looking to avoid emulsifiers, then you probably also want to avoid all ultra-processed food additives.

⚠️ 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.
