How to Find the Best Protein Powder for Liver Cirrhosis

Is Protein Powder Good for Liver Cirrhosis?

First of all, protein powder is not bad for your liver.

One review of experimental and randomized studies did find that frequent whey protein supplementation can cause adverse effects on liver function (Appl Physiol Nutr Metab, 2021), but examples of this are rare.

Generally speaking, if it helps you meet your protein needs, the benefits of adding protein powder to your diet outweigh any potential side effects.

Moreover, increasing the percentage of your calories that come from protein can help actually improve your liver health.

This is because one of the leading causes of liver liver cirrhosis is fatty liver disease.

Fatty liver disease is caused by the storage of fat in the liver, and although the exact cause is unknown, it is strongly associated with obesity.

It follows that losing just 10% of your body weight can significantly reduce liver fat and improve scarring (JAMA, 2020).

Moreover, adding protein powder to your diet can support weight loss because:

• Protein is the most satiating macronutrient, meaning it makes you feel full for longer than fats and carbs, which curbs cravings and overeating.
• Consuming protein increases thermogenesis, or your metabolic rate and energy expenditure.
• Consuming protein, in addition to lifting weights, can help you build muscle, and people with more muscle mass have faster metabolisms.

It is worth adding that some people with liver cirrhosis need extra protein to help repair damaged liver cells and prevent muscle wasting (sarcopenia).

In fact, it is recommended that adults with cirrhosis consume 1.2-1.5 grams of protein kilogram of body weight per day (Hepatology, 2021), which is well over 50% more than what most adults need.

Eating this much protein, especially if you have dietary restrictions, can be challenging.

And if you need help, adding protein powder to your diet can be a great idea.

Protein powder can be easily incorporated into smoothies, oatmeal, and other recipes, making it a great way to bridge nutritional gaps.

That said, if you do not need the extra protein, adding protein powder to your diet could contribute to weight gain.

For this reason, you should consult with a registered dietitian or other healthcare professional to determine if protein powder is right for you.

It is also important to note that not all protein powders are created equal.

What Is the Best Protein Powder for Liver Cirrhosis?

As long as you are eating a balanced diet – getting protein from a variety of sources – the type of protein powder you use does not matter.

The ingredients in your protein powder do matter, however.

Many protein powders contain ingredients known to gut health problems that might contribute to liver cirrhosis.

Among top offenders are food additives, dairy-based proteins, and protein concentrates and isolates.

🚫 Avoid Food Additives

Regularly eating emulsifiers, thickeners, and other additives can not only upset your stomach, but also alter the composition of your gut microbiome (North Clin Istanb, 2019).

These shifts, known as gut dysbiosis, have been linked to the development of several chronic liver diseases (JHEP Rep, 2019).

Although this connection is not yet fully understood, it is thought that increased intestinal permeability, chronic inflammation, and changes in short-chain fatty acid production are to blame.

⚠️ Here is a list of the most common food additives in protein supplements:

• 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 supplements 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 supplements made from minimally-processed protein sources like egg whites and almonds.

They are more gut-friendly.
