Protein Powder Without Artificial Flavors
What Are Artificial Flavors?
Artificial flavors are man-made compounds designed to mimic the taste of flavors found in nature.
They are often made from petroleum or other inedible sources.
Manufacturers add artificial flavors to many products, including protein powders, for a few reasons:
- Consistency: They create the same taste in every batch.
- Shelf Stability: They do not break down over time the way natural flavors do, so they can extend shelf life.
- Cost-Effectiveness: They are often cheaper to make and use than natural flavors and ingredients.
Most regulatory bodies consider artificial flavors safe to eat.
Even so, many people prefer to avoid them.
Are Artificial Flavors Bad for You?
Artificial flavors are not necessarily unsafe, but some people choose to avoid them for the following reasons:
- Ultra-Processed: They look nothing like real food.
- Additive-Laden: They often contain solvents, stabilizers, and carriers.
- Lacking in Nutrition: They have little to no nutritional value.
Regularly eating certain artificial flavors might also affect your gut health.
Specifically, it might alter the function and composition of your gut microbiome, which is the community of bacteria and other microbes living in your digestive tract (FASEB J, 2025).
These shifts, known as gut dysbiosis, have been linked to a wide range of chronic conditions, including obesity and type 1 diabetes (J Exp Med, 2019).
It is important to note that much of this research is still emerging, so more studies are needed to clarify these relationships.
That said, the preliminary findings suggest that because protein shakes and powders are something you consume regularly, if not every day, the cumulative effects of small amounts of potentially harmful ingredients is worth taking seriously.
Product Quiz
What Is the Best Protein Powder Without Artificial Flavors?
To know if a protein powder contains artificial flavors, read the ingredient list on the Supplement or Nutrition Facts panel.
And while you are there, check to see if there are any other food additives listed.
🚫 Avoid Food Additives
In addition to artificial flavors, many protein powders contain added emulsifiers, thickeners, and artificial sweeteners.
None of these ultra-processed ingredients look anything like real food, so I recommend avoiding them whenever possible.
⚠️ Here is a list of the most common food additives in protein shakes and powders:
- 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
As a rule of thumb, if you cannot find an ingredient in nature or make it at home, it is a food additive.
It is important to note that while food manufacturers must disclose their ingredients, flavor manufacturers do not have to disclose theirs.
They can add synthetic solvents, preservatives, and carriers to a flavor that still qualifies as “natural” under current rules (FDA regulations 21 CFR §101.22).
The term “natural flavor” could therefore act as a catch-all for everything a manufacturer would rather not spell out on the ingredient list.
In my opinion, this makes natural flavors as questionable as, if not more questionable than, artificial flavors.
At least artificial flavors are labeled as artificial.
🚫 Avoid Protein Concentrates and Isolates
I also recommend avoiding protein concentrates and isolates.
Most protein shakes and powders are made from one or both of these ultra-processed protein sources, which have been mechanically and/or chemically stripped of everything but the protein.
This includes the enzymes, fiber, and other natural digestive aids that help you break them down.
You therefore might not digest them in the same way that you do whole foods, which could affect your gut health.
For example, one study shows that regularly consuming protein concentrates and isolates might disrupt your gut microbiome (Nutrients, 2018).
Another study shows that it could cause the formation of toxic byproducts in your gut (Mol Nutr Food Res, 2024).
Although further research is needed, you can play it safe by choosing protein shakes and powders made from minimally-processed protein sources like egg whites and almonds.
Our customers find them to be more gut-friendly.

Frequently asked questions
Who Is Drink Wholesome for?
Drink Wholesome makes protein powder for sensitive stomachs, GERD, IBS, and other gut issues. It’s suitable for most food sensitivities, including lactose intolerance, and won’t cause side effects like bloating, constipation, and reflux.
Why Is Drink Wholesome Good for Sensitive Stomachs?
Drink Wholesome is the best protein powder for sensitive stomachs because it’s additive, dairy, and gluten-free. It’s also made from minimally-processed protein sources like egg whites and almonds. Other protein powders are made from ultra-processed protein concentrates and isolates, which look nothing like real food.
What’s the Difference Between Protein Powder and Meal Replacement Powder?
Drink Wholesome makes gut-friendly Protein Powders and Meal Replacement Powders. Protein powder is high in protein and low in everything else, whereas meal replacement powder contains fats, carbs, fiber, and protein because it’s intended to replace the nutritional value of a balanced meal.
What’s the Difference Between Almond, Collagen, and Egg White Protein?
We make three types of stomach-friendly Protein Powder: Collagen Protein Powder, Egg White Protein Powder, and Vegan Almond Protein Powder. As long as you get protein from a variety of sources, any type of protein can help you meet your total daily protein needs. In other words, for someone with a balanced diet, there is no advantage to consuming one type of protein over another. Order Samples to see which type you like the most.
