Is Protein Powder Good for Wound Healing?

Dietary protein intake plays an important role in tissue formation and repair (Evid Based Complement Alternat Med, 2022).

Moreover, when you suffer an injury, your body needs extra protein to build and repair the damaged tissue.

It is recommended that you consume 1.2-1.5 grams of protein per kilogram body weight per day while recovering from a tissue injury (N Engl J Med, 2024), which is a lot more protein than you would normally need.

Although you should try to get as much protein as you can from foods like eggs, fish, and meat, meeting your protein needs this way can be challenging.

People with dietary restrictions or reduced appetite, for example, may not be able to eat enough protein.

Adding protein powder to your diet can thus be a great way to ensure that you are getting enough protein to heal.

It can be incorporated into smoothies, oatmeal, and other recipes, or simply mixed with milk or water to make a protein shake.

Which Type of Protein Powder Is Best For Wound Healing?

You may have heard that Collagen Protein Powder is the best protein powder for wound healing, but this is not true.

Although collagen is one of the main components of tissue, eating lots of collagen will not help you build or repair tissue faster or better than eating any other type of dietary protein.

This is because the proteins that make up your tissues are synthesized (made) by your body, meaning they do not come directly from food.

In order to synthesize collagen or any other type of protein, your body simply needs amino acids.

As a reminder:

• Amino acids are the building blocks of protein.
• There are 20 amino acids in the human body, 9 of which are essential, meaning you must get them from food.
• A dietary protein with all 9 essential amino acids is considered a complete protein.

In most cases, eating a balanced diet (getting your protein from a variety of sources), will give you all the essential amino acids you need to support wound healing.

If you are relying heavily on protein shakes or powders to meet your nutritional needs, however, you may want to prioritize protein shakes or powders made from complete proteins.

In this case, collagen protein powder would not be the best option as it does not have a complete amino acid profile.

Whey or Egg White Protein Powder would be a better choice.

What Is the Best Protein Powder for Wound Healing?

Not all protein shakes and powders are created equal.

Many protein shakes and powders are made from ingredients known to cause painful digestive issues and long term gut health problems, which can impair wound healing.

Among these ingredients are food additives 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 (the collection of microorganisms living in your gut) (North Clin Istanb, 2019).

This can lead to gut dysbiosis, or an imbalance in gut bacteria, which can induce immune dysregulation, making you more susceptible to infection (Microorganisms, 2022; Microorganisms, 2020).

Furthermore, because your gut microbiome also helps you break down and absorb food, when it is not working properly, certain nutrients (like proteins) do not make it into your bloodstream, which can hamper the healing process.

⚠️ 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

You might also want to avoid ultra-processed 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 your gut break them down.

You therefore do not digest them in the same way that you do whole foods, which could affect your gut health.

Studies show that regularly eating protein concentrates and isolates might disrupt your gut microbiome and cause the formation of toxic byproducts in your gut (Nutrients, 2018; Mol Nutr Food Res, 2024).

You should thus look for protein shakes or powders made from whole food protein sources like egg whites and almonds, which are easier to digest and absorb.
