What’s in your protein powder?

Drink Wholesome is made with 100% real foods.

NO dairy.

Drink Wholesome is dairy-free. Dairy is one of the main reasons why protein powder causes stomach pain. Whey protein – including whey protein concentrate, whey protein isolate, and hydrolyzed whey protein – contains dairy. So does casein protein. 

Millions of American adults are lactose intolerant, meaning that they are unable to fully digest lactose, the sugar in milk. They therefore experience stomach pain when they consume dairy. If your whey or casein protein powder causes stomach pain, you may be lactose intolerant.

Egg whites.

Most protein powders are made with protein concentrates and isolates, foods stripped of everything but the protein. They are listed as “whey protein” and “pea protein” as opposed to “whey” and “peas.”

Our protein powders are made with egg whites. We like egg whites because they were simply broken, pasteurized, and dried. Protein concentrates and isolates, on the other hand, were subjected to heavy chemical and/or mechanical processing. The end result is something that looks nothing like real food. 

This matters because real foods are good for your stomach. The closer a food is nature, the less likely it is to cause stomach pain.

NO food additives.

Drink Wholesome is the ONLY protein powder made with 100% real foods. Most protein powders are full of food additives.

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 nasty side effects.

Because food additives look nothing like real foods, we have trouble digesting them. As a result, the trillions of bacteria in our guts have more time to eat and more time to release gas. This gas can cause bloating and stomach pain.

Accumulating evidence suggests that food additives also disrupt regulatory pathways in the intestine and can result in 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 are some 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. Recent research suggests that artificial sweeteners are particularly bad for the stomach because they alter the composition of our gut microbiota.
