What Are Milk Products in Protein Powder?

Why Should I Use Protein Powder Without Milk Products?

A milk product is any food, beverage, or ingredient made from milk or derived from milk.

Common milk products include cheese, yogurt, butter, whey, and casein.

Some food additives are also milk products.

A popular example is sodium caseinate, which is added to many products, including protein powder, as an emulsifier and thickener.

If you are wondering if your protein powder contains milk or a milk derivative, just read the ingredient list.

Supplement manufacturers are required to declare major food allergens, such as milk, either in parentheses following the name of the ingredient, or immediately after the list of ingredients in a “contains” statement (FDA, 2024).

And if you are wondering if protein powder without milk products is right for you, consider the following:

  • Lactose Intolerance: Many people cannot fully digest lactose, a sugar in milk, which can cause symptoms such as bloating and stomach pain.
  • Dairy Allergy: Some people are allergic to milk, which can cause severe allergic reactions.
  • Hormone and Antibiotic Concerns: Some dairy products can contain traces of hormones and antibiotics, which might have effects on human health, though the extent and significance is debated (Eur J Endocrinol, 2018).
  • Environmental Impact: Industrial dairy farming has a large environmental footprint, including greenhouse gas emissions, water use, and land degradation.
  • Skin Health: Some research suggests a link between dairy consumption and acne or other skin issues, possibly due to hormones in milk (JAMA, 2021).
  • Plant-Based Diet: Some people avoid dairy, which is an animal product, because they are on a plant-based diet.

In short, a protein powder without milk products can help individuals with lactose intolerance, dairy allergies, and other dietary preferences to safely and comfortably meet their protein needs.

What Is the Best Protein Powder Without Milk Products?

A protein powder without milk products is necessarily dairy-free.

Keep in mind that “non-dairy” does not mean dairy-free.

Non-dairy is an FDA-regulated term that permits small amounts of milk derivatives.

Also note that “lactose-free” does not mean “dairy-free.”

Some protein powders have had virtually all of the lactose “removed” (broken down) by addition of the enzyme lactase.

But the milk proteins (whey and casein) remain fully intact.

All whey and casein proteins are dairy (milk) products.

It is worth adding that dairy-based proteins like whey and casein often cause digestive issues because they contain lactose.

But you might be sensitive to dairy-based proteins even if you are not lactose intolerant.

This is especially true for casein protein, which forms a gel-like substance in your stomach that slows down digestion (Crit Rev Food Sci Nutr, 2023).

It is also worth noting that if you have a sensitive stomach, milk products are not the only thing you should avoid.

Many protein powders contain several other ingredients known to cause painful digestive issues and even long-term gut health problems.

avoid food additives

🚫 Avoid Food Additives

Emulsifiers, thickeners, and other ultra-processed additives can alter the composition and function of your gut microbiome (North Clin Istanb, 2020).

These shifts, known as gut dysbiosis, have been linked to a number of chronic digestive issues (JGH Open, 2021).

Gut dysbiosis is so problematic because it causes a cascade of problems, including intestinal permeability and systemic inflammation.

⚠️ 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 an ingredient in nature or make it at home, it is probably a food additive.

avoid ultra processing

🚫 Avoid Protein Concentrates and Isolates

If you have a sensitive stomach, you might also want to avoid 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 you break them down.

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

For example, one study shows that regularly consuming protein concentrates and isolates might disrupt your gut microbiome (Nutrients, 2018).

Another study shows that it could cause the formation of toxic byproducts in your gut (Mol Nutr Food Res, 2024).

Although further research is needed, individuals with sensitive stomachs can play it safe by choosing protein supplements made from minimally-processed protein sources like egg whites and almonds.

They are more gut-friendly.

Frequently asked questions

Who is Drink Wholesome for?

Drink Wholesome makes minimally-processed protein powder for sensitive stomachs. Because our protein powder is additive, dairy, and gluten-free and made from a short list of simple ingredients, it’s a great option for people with lactose intolerance, IBS, GERD, and SIBO.

Why is Drink Wholesome easy to digest?

No Dairy 

Drink Wholesome is made without whey and casein, which often contain lactose, a sugar most people can’t fully digest. Some caseins also release a bioactive peptide during digestion that has been linked to digestive issues in some individuals.

No Additives

Drink Wholesome is made without food additives. Regularly eating certain emulsifiers, thickeners, and other ultra-processed additives can contribute to gut dysbiosis, which has been linked to chronic digestive issues.

Whole Food Protein

Other protein powders are made from ultra-processed protein concentrates and isolates, which have been mechanically and/or chemically stripped of non-protein components that promote digestion. Drink Wholesome, on the other hand, is made from whole food protein sources, which might be more gut-friendly.

Collagen vs egg white vs almond protein powder?

We make three types of minimally-processed Protein Powder for sensitive stomachs: Collagen Protein Powder, Egg White Protein Powder, and Vegan Almond Protein Powder. As long as you eat a balanced diet, any type of protein powder can help you meet your protein needs. So just pick the type that best suits your personal preferences.
