Toddler Protein Powder

Can Toddlers Have Protein Powder?

Feeding toddlers (children between the ages of 1 and 3) can be challenging because several developmental changes are happening in a toddler at same time.

For starters, human growth rate slows considerably after the first year of life.

Babies typically double in weight by the time they are 6 months old, but toddlers only put on about 5 pounds each year.

A slower growth rate is usually paired with a smaller appetite.

Toddlers are also striving for independence and control, especially when it comes to food.

It is between the ages of 1 and 3 that many children become picky eaters, which can make mealtime difficult.

As a result, some children do not get enough of the nutrients that they need.

Among these nutrients is protein, which is essential for growth and development.

Protein is found in every cell of the body, serving as one of the building blocks of muscles, skin, and bones.

It is also a key component of antibodies that protect the body against illness.

If you are concerned that your child is suffering from a protein deficiency, consult a pediatrician immediately.

Although protein needs for toddlers vary from child to child, toddlers should eat at least 0.9 grams of protein per kilogram of body weight per day (Food Nutr Res, 2013).

For most toddlers, this amounts to 10-12 grams of protein.

Most toddlers should be able to get this much protein from foods like eggs, legumes, and meat, but some toddlers may need a little help.

Picky eaters and toddlers with dietary restrictions, for example, may benefit from a protein powder, which can be easily added to smoothies, oatmeal, and other recipes for extra protein.

That said, not all protein powders are created equal.

What Is the Best Protein Powder for Toddlers?

If a toddler is eating a balanced diet, the type (egg, pea, whey, etc.) of protein powder he or she uses does not matter.

Ingredients do matter, however.

Many protein powders contain ingredients known to cause painful side effects and even long-term health problems.

Among these ingredients are food additives, dairy-based proteins, and protein concentrates/isolates.

🚫 Avoid Food Additives

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

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

Needless to say, finding an additive-free protein powder for your toddler is super important.

⚠️ 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.
