Protein powder and dairy allergies
What is a dairy allergy?
A dairy allergy, also known as a milk allergy, is an adverse immune response to proteins in milk and dairy products. It is one of the most common food allergies, especially in infants and young children.
Dairy contains several proteins that which trigger an allergic reaction, the two most common being casein and whey.
When someone with a dairy allergy consumes casein and whey, their immune system mistakenly identifies these proteins as harmful and mounts an immune response. This response can cause rashes, swelling, digestive symptoms, respiratory issues, and, in severe cases, anaphylaxis.
Dairy allergies are different from lactose intolerance, which is the inability to completely digest lactose, the sugar in milk.
Lactose intolerance typically causes gastrointestinal side effects like gas, bloating, and diarrhea, whereas a dairy allergy involves an immune response that can lead to a wider range of symptoms.
What is the best protein powder for dairy allergy?
If you have a dairy allergy, you cannot consume protein powders made with casein or whey protein.
You must also avoid common dairy-based food additives like sodium caseinate.
Depending on the severity of your allergy, even small amounts of ingredients like these can trigger an allergic reaction.
Keep in mind that “non dairy” does not mean “dairy-free.”
Companies can legally label their products as “non dairy” when they contain whey or another dairy derivative.
Likewise, lactose-free does not mean dairy-free. Some whey protein powders have had virtually all of the lactose removed, but they are certainly not dairy-free.
If you have a dairy allergy, or any food allergy, is it essential that you read the ingredient label.
Food and supplement manufacturers are required to declare major food allergens like dairy, either in parentheses following the name of the ingredient, or immediately after the list of ingredients in a “contains” statement. Example: “Contains Milk.”
As long as a protein powder does not contain whey, casein, or a dairy-based food additives, it will be safe for people with dairy allergies.
That said, not all dairy-free protein powders are created equal.
Unfortunately, many protein powders are made with so much processing and so many added ingredients that they look nothing like real food, which is not a good thing. Keep reading to learn more.
Many protein supplements contain added ingredients that although dairy-free, can cause painful side effects and long term health problems. Among these ingredients are food additives and protein concentrates and isolates.
Avoid food additives
Emulsifiers, thickeners, sugar substitutes, and other additives are heavily-processed derivatives of real food that have no place in your diet.
Moreover, these additives can upset your stomach and alter the composition of your gut microbiome – the collection of microorganisms living in your gut.
This can lead to gut dysbiosis, or an imbalance in gut bacteria, which contributes to wide range of chronic diseases, including obesity, type 1 diabetes, and colorectal cancer.
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
Avoid protein concentrates and isolates
Most protein supplements are made from protein concentrates and isolates, which have been mechanically and or chemically stripped of everything but the protein, including the enzymes, fiber, and other natural digestive aids that help you break them down.
As a result, they can cause digestive issues and possibly even disruptions to your gut microbiome.
Finding a protein supplement free from food additives and protein concentrates and isolates is hard.
In fact, 99% of protein supplements contain one or both of these problematic ingredients, which is why we created drink wholesome. Keep reading to learn more about why we make the best protein powder for people with dairy allergies.

Verified Purchase As someone who has struggled with chronic conditions for 10+ years, getting in nutrient-dense foods is big part of how I care for my body. Finding options that are tasty and convenient is difficult. And I am always trying to eat enough in order to maintain my weight. Providers consistently recommend smoothies/shakes. I have tried so many over the years and each time the GI symptoms are intense or the flavor is awful! Since finding Drink Wholesome, I have finally been able to incorporate higher protein smoothies and shakes without the digestive upset. As a result, I have been able to maintain my weight more easily and even gain some beneficial weight. digestive issues

Whole Food Protein
Drink Wholesome is made from whole food protein sources like almonds and egg whites. Unlike ultra-processed protein concentrates and isolates, which have been stripped of fiber, enzymes, and other natural digestive aids, whole foods are easy to break down and absorb.
