Our Egg White + Collagen Protein Powder Won’t Upset Your Stomach
It’s Jack, the founder of Drink Wholesome.
Our gut-friendly Egg White + Collagen Protein Powder can help you meet your protein needs without upsetting your stomach.
It’s recommended for sensitive stomachs, GERD, IBS, and other gut issues, and if it upsets your stomach, it’s free!
I created Drink Wholesome because the artificial and ultra-processed ingredients in other protein powders upset my stomach.
You won’t find a protein powder that’s easier to digest…Trust me, I’ve tried.

Why Is Our Egg White + Collagen Protein Powder Good for Sensitive Stomachs?
There are 3 types of protein powder ingredients that are notorious for causing digestive issues:
1) food additives, 2) dairy-based proteins, and 3) ultra-processed protein concentrates and isolates.
99% of protein powders contain one or more of these problematic ingredients, whereas Drink Wholesome doesn’t.
In fact, there’s nothing in Drink Wholesome that might upset your stomach.
Just look at the short list of simple ingredients!
My Ingredients
egg whites
strawberries
coconut
monk fruit
NOT My Ingredients
- acacia gum
- acesulfame potassium
- artificial flavors
- carrageenan
- erythritol
- guar gum
- inulin
- maltodextrin
- 'natural' flavors
- silica
- soy lecithin
- sucralose
- xanthan gum
- xylitol
It's Additive-Free
Our Egg White + Collagen Protein Powder doesn’t contain any food additives whatsoever.
This is good news for sensitive stomachs because certain additives – like artificial sweeteners, emulsifiers, and thickeners – are notorious for causing digestive issues (FASEB J, 2025).
There are many reasons why food additives might upset your stomach, and individual tolerances vary.
That said, most food additives are ultra-processed, meaning they look nothing like real food.
This could make them hard to break down and absorb, contributing to side effects like bloating, diarrhea, and stomach pain.
Certain food additives have also been shown to alter the composition of your gut microbiome – the collection of microorganisms living in your gut (Eur J Nutr, 2020).
These shifts, known as gut dysbiosis, might contribute to chronic digestive issues (J Appl Microbiol, 2020).
Gut dysbiosis can cause a self-reinforcing cascade of problems, including leaky gut and poor nutrient absorption (Crit Rev Food Sci Nutr, 2022; Microorganisms, 2023).
Much of this research is still emerging, so more studies are needed to clarify these relationships.
But because protein powder is something you consume regularly, even small amounts of potentially harmful ingredients are worth taking seriously.
It's Dairy-Free
Our Egg White + Collagen Protein Powder is free from dairy-based proteins like whey and casein.
Whey and casein contain lactose – a sugar most people can’t fully digest – but you might be sensitive even if you’re not lactose intolerant (Am J Clin Nutr, 2019).
For starters, some caseins release a compound during digestion that has been linked to digestive issues (Adv Nutr, 2017).
Casein also forms a gel-like substance in your stomach that slows down digestion (Crit Rev Food Sci Nutr, 2023).
For some, slow digestion can contribute to bloating and other digestive side effects.
It’s Minimally-Processed
Our Egg White + Collagen Protein Powder is made from minimally-processed protein sources, not ultra-processed protein concentrates or isolates.
Protein concentrates and isolates have been mechanically and/or chemically stripped of everything but the protein.
This includes fiber, enzymes, and other natural digestive aids that help you break them down.
You therefore might not digest concentrates and isolates in the same way that you do real foods (J Agric Food Chem, 2023; Foods, 2022).
This could lead to gut fermentation, which has been linked to gut inflammation and chronic digestive issues (Crit Rev Food Sci Nutr, 2017; Mol Nutr Food Res, 2024).
One study even suggests the consumption of concentrates and isolates could alter the composition of your gut microbiome (Nutrients, 2018).
For the record, protein concentrates and isolates are generally well-tolerated.
But they might be problematic for people with sensitive stomachs.
That’s why we use egg whites and bovine collagen peptides, which our customers find to be easier to break down and absorb.
99% experience no digestive issues with our Egg White + Collagen Protein Powder.

Verified Purchase The only protein powder I buy! Amazing for anyone who has a sensitive tummy… digestive issues
Verified Purchase Your product actually rocks. I've had a lot of protein powders before and this is a winner!
Verified Purchase I did think it was tasty, but feel like it needs more strawberry. It tastes like coconut to me and that’s it. I also wish it came with a scoop like other protein powders. Loved that there was a little recipe on the back. And love that it actually is made of literally a few ingredients!
Verified Purchase I LOVE your plain, nothing else egg white powder! Please don't ever discontinue that! It meets my needs because I can't tolerate alternative sweeteners such as monk fruit. When adding your egg whites to smoothies, fruit makes it sweet enough for me. digestive issues
Verified Purchase I mix the maple protein powder into my buckwheat cereal and it is delicious.
Verified Purchase The golden milk tastes like chicken soup. It's bad.

Frequently Asked Questions
What Is Egg White + Collagen Protein Powder?
Our Egg White + Collagen Protein Powder is a gut-friendly protein source for sensitive stomachs. It’s made from pasteurized egg whites – the clear liquid that surrounds the yellow yolk of an egg – as well as bovine collagen peptides (Types I & III), which are tiny pieces of cowhide from pasture-raised cows. It can help you meet your total daily protein needs without upsetting your stomach.

Our Egg White + Collagen Protein Powder can be added to smoothies, oatmeal, and other recipes, or mixed with just milk or water.
