No dairy.

Drink Wholesome is dairy-free. Dairy is the main reason why protein powder causes stomach pain. Whey protein, including whey protein concentrate, whey protein isolate, and hydrolyzed whey protein all contain dairy. So does casein protein. Both are byproducts of cheese production. 

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

Egg whites.

The main ingredient in our protein powders is egg whites. Of all the whole foods, eggs have the highest protein digestibility corrected amino acid score (PDCAAS), which is a measurement of both a protein’s effectiveness and digestibility. The PDCAAS is determined by comparing the amino acid profile of the protein against a standard amino acid profile, with 100 as the highest possible score. Eggs come in at 100. The protein in eggs is therefore easily absorbed into and used by the body.

The eggs we use are also minimally processed. They were broken, pasteurized, and dried. That is it. Remember, the closer your food is to nature, the easier it is to digest. Most protein powders look nothing like real food. They are made with highly processed protein isolates stripped of everything but the protein.

Protein isolates are made by taking a raw ingredient and subjecting it to a variety of isoelectric precipitation and ultrafiltration processes, some of which are chemical and some of which are mechanical. I will spare you the details, but you should know that what ends up in your protein powder looks utterly unnatural.

NO food additives

Drink Wholesome is made with 100% real foods, foods close to nature. Food additives are not real foods – not even close – and most protein powders are full of them. 

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.  

One of the most common side effects caused by food additives is stomach pain. 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 discomfort. 

As a rule of thumb, avoid ingredients you cannot pronounce or find in your kitchen. 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, guar gum, gum arabic, inulin, locust bean gum, “natural” flavors, maltodextrin, rice syrup solids, soy lecithin, silica, sucralose, sunflower lecithin, xanthan gum, xylitol

Included in this list are several artificial sweeteners. Artificial sweeteners can cause stomach pain too because they alter the composition of our gut microbiota.
