What is in your protein powder?

Drink Wholesome is the ONLY protein powder made with 100% real foods. Our chocolate protein powder, for example, is made with egg whites, coconut, cocoa, and monk fruit. Ingredients like these are good for you, and unless you have a food allergy, none of them will upset our stomach. 

NO dairy.

Dairy is the main reason why casein and whey protein powder cause stomach pain. Casein and whey, two of the most popular ingredients in protein supplements, are byproducts of cheese and yogurt production. They may upset your stomach, especially if you are lactose intolerant. People who are lactose intolerant cannot fully digest lactose, the sugar in milk. Switch to a dairy-free protein powder like Drink Wholesome if your casein or whey protein powder causes side effects. 

Egg whites.

Most protein powders are made with protein concentrates and isolates, foods chemically and/or mechanically stripped of everything but the protein. They are listed on the ingredient list as “whey protein” and “pea protein” as opposed to “whey” and “peas.”

The main ingredients in our protein powders are egg whites and chickpeas. Egg whites are simply broken, pasteurized, and dried before becoming protein powder. Chickpeas are simply dried and ground. Unlike protein concentrates and isolates, which undergo heavy processing, egg whites and chickpeas look like real food. This matters because the more an ingredient looks like real food, the easier it is to digest.

NO food additives.

Most protein powders are full of food additives.

Most protein powders are full of food additives. Why does this matter? Although food additives are not necessarily bad for you in small quantities, they can add up quickly, especially if you drink a protein shake every day. At higher quantities, food additives can cause side effects.

Because food additives are heavily processed and look nothing like real foods, we can have trouble digesting them. As a result, they sit in our guts for longer and ferment. Fermentation produces gas, which can cause bloating, cramps, and stomach pain. It can also slow colonic transit and lead to constipation. 

Food additives can also disrupt regulatory pathways in the intestine and cause the development of inflammatory bowel disease (IBD) and systemic inflammatory disorders. This is a good reason to avoid food additives if you have a sensitive stomach. 

As a rule of thumb, food additives are ingredients that you cannot pronounce. Not sure what to look for? Here is a list of the most common additives in protein powder: 

acacia gum, acesulfame potassium, artificial flavors, aspartame, carrageenan, cellulose gum, dextrin, dextrose, erythritol, gellan gum, guar gum, gum arabic, inulin, locust bean gum, “natural” flavors*, maltodextrin, rice syrup solids, soy lecithin, silica, sucralose, sunflower lecithin, xanthan gum, xylitol

You may have noticed that this list includes several artificial sweeteners. Some artificial sweeteners may be bad for the stomach because they alter the composition of our gut microbiota, the collection of microorganisms that help us digest food. This can lead to serious stomach pain and widespread inflammation. Some artificial sweeteners, especially sugar alcohols like xylitol, can also cause diarrhea because they draw water into the gut.
