Protein Powder for Height Growth

Can Protein Powder Help With Height Growth?

Protein is essential for the growth and development of every child.

Moreover, research has shown a positive correlation between protein intake and height growth at a young age (Econ Hum Biol, 2016).

Although height is largely genetic, good nutrition during childhood and adolescence can impact how tall a person becomes.

If you are concerned that your child is suffering from a protein deficiency, please consult a pediatrician; malnutrition is not something to be taken lightly.

If you are just looking for a quick and easy way to get more protein into your kid’s diet, however, then protein powder might be a good option.

That said, protein supplements should not replace other protein sources.

Whenever possible, children should get their protein from foods like eggs, fish, and meat.

For most kids, this should be enough to cover their protein needs.

Some kids, such as picky eaters and those with dietary restrictions, may need an protein boost, however.

In this case, protein powder can be a lifesaver.

It can be easily mixed with milk or water to make a protein shake, or added to oatmeal, yogurt, and kid-friendly recipes like pancakes.

Keep in mind that protein powder is just food, that is, it alone will not miraculously trigger height growth.

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

What Is the Best Protein Powder for Height Growth?

Any type of protein powder (egg white, pea, whey, etc.) can help your kid meet 100% of his or her daily protein needs.

In other words, as long as he or she is eating a balanced diet, there is no advantage to using one type of protein powder over another.

Ingredients do matter, however.

Most protein powders contain ingredients that can cause painful side effects and long term health problems for kids.

Among these ingredients 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 a kid’s stomach, but also alter the composition of his or her gut microbiome (the collection of microorganisms living in his or her gut) (North Clin Istanb, 2019).

This can lead to gut dysbiosis, or an imbalance in gut bacteria, which contributes to the development of several chronic diseases, including allergies, asthma, and obesity (Microorganisms, 2022; Microb Ecol Health Dis, 2015).

Because the gut microbiome affects physiological processes like immune function and inflammation, when the balance of bacteria therein is disrupted, it can have a huge impact on your kid’s health.

⚠️ 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 Dairy-Based Proteins

Dairy-based proteins like whey and casein, although not an issue for everyone, can cause digestive issues.

This is usually because they contain lactose, a sugar many individuals with sensitive stomachs cannot fully digest.

But you might be sensitive to dairy-based proteins even if you are not lactose intolerant.

This is particularly true for casein protein, which forms a gel-like substance in your stomach that slows down digestion.

🚫 Avoid Protein Concentrates and Isolates

You might also want to avoid ultra-processed 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 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 supplements made from whole food protein sources like egg whites and almonds, which are easier to digest and absorb.
