How to Find the Best Low Phosphorus Protein Powder
📌 Overview and Key Takeaways
This is a Certified Nutrition Coach’s guide on how to find the best low phosphorus protein powder.
Discover how to safely meet your protein needs on a low phosphorus diet.
Low Phosphorus Protein Powder
Why Should I Choose a Low Phosphorus Protein Powder?
A low-phosphorus diet limits phosphorus intake, which is a critical consideration for anyone managing Chronic Kidney Disease (CKD).
When your kidney function is impaired, your kidneys lose their ability to filter excess phosphorus from the blood.
This buildup, known as hyperphosphatemia, can trigger a cascade of serious health problems, including bone and joint pain, cardiovascular damage, persistent skin itching, and dangerous heart complications.
Those on dialysis are especially at risk and advised to monitor phosphorus intake carefully.
Dialysis itself also depletes protein from the body, meaning that many dialysis patients require significantly more than the average person: 1-1.2 grams of protein per kilogram of body weight per day (Diabetes Care, 2025).
Unfortunately, this creates a challenging balance as many high-protein foods are also high in phosphorus.
A low-phosphorus protein powder thus offers a practical solution, delivering the protein dialysis patients need in a form that will not significantly burden their phosphorus load.

Which Protein Powders Are Low Phosphorus?
In general, dairy and soy-based proteins tend to have the highest phosphorus levels, whereas egg white and collagen-based proteins tend to have the lowest.
Egg White Protein Powder and Collagen Protein Powder are therefore the best protein sources for people with CKD, especially those undergoing dialysis treatment.
Egg whites can also lower phosphorus levels in the blood (J Ren Care, 2011).
Egg whites do contain a moderate amount of sodium, however, so if this is a concern for you, then collagen protein powder might be the better option.
Keep in mind that added ingredients can contribute phosphorus.
Phosphate-based additives, in particular, can significantly increase phosphorus content.
Common examples include:
- Calcium phosphate
- Sodium phosphate
- Potassium phosphate
- Dipotassium phosphate
Also keep an eye out for added vitamins and minerals, as they too can contain phosphorus.
It follows that depending on your recommended phosphorus intake, you might want to choose a single-ingredient egg white or collagen protein powder.
Consult with a trusted healthcare professional to determine how much phosphorus is safe for you to consume.

What Is the Best Low Phosphorus Protein Powder?
Not all low phosphorus protein powders are created equal.
As long as you are eating a balanced diet – getting protein from a variety of sources – there is no advantage to using one type of protein over another.
Ingredients do matter, however, especially if you have pre-existing gut issues.
Food additives and protein concentrates and isolates, for example, might indirectly contribute to CKD via disruptions to your gut microbiome – the collection of microorganisms living in your digestive tract.
🚫 Avoid Food Additives
Regularly eating certain emulsifiers, thickeners, and other ultra-processed additives can alter the composition and function of your gut microbiome (North Clin Istanb, 2019).
These shifts, known as gut dysbiosis, might contribute to the development of kidney disease (Front Med, 2021).
This link exists because imbalances in gut bacteria can result in the increased production of uremic toxins, which, in turn, can exacerbate local and systemic kidney inflammation.
⚠️ 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 it in nature or make it at home, it is probably a food additive.
🚫 Avoid Protein Concentrates and Isolates
If you have a sensitive stomach, you might also want to avoid 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 do 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, individuals with sensitive stomachs can play it safe by choosing protein shakes and powders made from minimally-processed protein sources like egg whites and almonds.
They are 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.
