10 Best Protein Powder for Kids: Our Reviews + Pros & Cons!

The best kids’ protein powders should be organic, non-GMO, with no added fillers, colors, or dyes. If you’re vegan, look for a healthy plant protein like pea. Kids who can tolerate dairy will benefit greatly from single-ingredient whey protein isolate.

If children are eating a balanced diet that includes a variety of fruits, vegetables, lean meats, and grains, then they should be getting the right amount of protein.  But sometimes that’s not always possible.

Whether your child is a picky eater or you need a convenient way to add some extra protein to their breakfast, protein powder might be a good choice.

However, if you are looking to add a protein powder to your child’s diet, there are a few things you need to know first.

We have picked our favorite powders that are not only full of protein but are also free from any artificial colorings, sweeteners, and things your growing child does not need.

Before you add a protein powder to your child’s diet, keep reading to find out what you need to know to choose the best protein powder for kids, including why protein is important, how much protein your child needs, and more.

DISCLAIMER: Many of the protein powders in this post will be labeled with adult serving sizes. While these products are safe for the whole family, please make sure to adjust accordingly to ensure your child is getting the right amount of protein.

You may also want to check with your child’s doctor before supplementation to see if it’s right for them.

In a Hurry? Here’s Our Top Picks!


Why is Protein Important?

Protein is necessary for every cell in your body.  It repairs and builds tissue in your body and is the building block for bones, cartilage, muscle, and skin. It also regulates hormones, is a part of an enzyme for digesting food, and helps carry oxygen through the body.

Like carbohydrates and fat, it is a macronutrient and is something that your body must have in order to survive.  Needless to say, protein is crucial for both kids and adults.  But more does not equal better.

How Much Protein Powder Do Kids Need?

Children need 1 gram of protein for every 1 kilogram of body weight.  So for example, if your child weighs 50 pounds, which is 22.6 kilograms, then your child would need 22 grams of protein.

Keep in mind that a protein supplement can have up to 80 grams of protein per serving, which is entirely way too much protein for a child. Choose a nutritional shake that is suitable for your child’s weight.

Things to Watch Out for in Protein Powders

If you choose to give your child a protein powder supplement, here are some things to keep in mind when shopping for one:

  • Make sure the ingredients list is as short as possible. Look for protein powders that consist mainly of, well, protein. For example, a pea protein powder would list peas or pea protein isolate as an ingredient. If possible, look for organic and non-GMO options. These won’t contain any nasty additives that are unhealthy for your child to consume.
  • Stay away from powders with sugar or artificial sweeteners. Artificial anything isn’t good for kids, so aim to find a natural option.
  • Look for protein powders with a “GMP” label on them. GMP stands for Good Manufacturing Practices and means that the protein powder was produced in a facility that discloses all the ingredients in the protein powder because it follows the best industry practices.
  • Be sure to check the serving size and how much protein one serving contains. Know how much protein your child needs and be sure to not exceed that amount.

Our Top 10 Picks for Kids Protein Powder

Whether you have a picky eater who won’t eat high-protein foods, or you are looking to give your child a nutritional boost, check out these top protein powders for kids. 

We looked for protein powders that contain ingredients that aren’t harmful to kids’ growing bodies. We had our kids give these a try, so we weren’t about to even try something that might not be good for them.

All of these passed our initial no-nasty-ingredients test.

DISCLAIMER: Many of the protein powders on this list will be labeled with adult serving sizes.  Make sure to adjust accordingly to ensure your child is getting the right amount of protein.

These are the 10 kids protein powders that made the cut! (Plus what we liked and didn’t like about each one.)

It is strongly suggested you mix it into a fruit smoothie or juice, because our kids pretty much hated the flavor. The flavor isn’t strong, but not pleasant on its own.

  • NO UPSET STOMACH – Simple ingredients...

This unflavored protein powder contains just 2 ingredients: whey protein isolate and less than 1 percent of non-GMO sunflower lecithin.  That’s it.

We like the sunflower lecithin because it keeps the powder from clumping but it’s also great for kids’ brains! Sunflower lecithin is pretty much a superfood on its own, so adding it to our protein drinks is a win-win.

This whey protein isolate is made from milk from hormone-free grass-fed cows.  Kids will not only get a healthy dose of protein but calcium and vitamin A as well.

The powder mixes easily into our kid’s favorite smoothies and drinks. They like this one. It can also be added to favorite recipes like pancakes to amp the nutrition in things they already eat. 

Since it is unflavored, it is more versatile than other protein powders.

What We Like:

  • Only two ingredients! No sugars, sweeteners, or preservatives
  • Gluten-free and non-GMO
  • Unflavored making it versatile to put in virtually any drink, smoothie, or food

One serving of this protein powder will give you 21 grams of plant-based protein that comes from peas, brown rice, and chia seeds. 

This one has zero sugar, so it is a healthy protein powder choice for the kids. Some of the protein powders they liked better had a little added sugar, but then we didn’t want to give it to them as much. So this one is a better choice.

If your little one has a sensitive tummy, this particular protein powder has probiotics to make digestion a little easier.  It’s also full of vitamins including Vitamin D, Vitamin A, Zinc, Iron, Vitamin E, and more.

We are big fans of Garden of Life products, and this protein powder for kids is no exception. It’s like a healthy feast for the body in each scoop.

The ingredients list might seem a little daunting to look at, but it contains all organic, natural ingredients. 

The 22 grams of protein per serving comes from a variety of plant-based sources including pea, brown rice, various grains, chia, and others.

It also has a variety of probiotics and enzymes (3 billion CFUs) to help your little one digest this powder. If you have kids with constipation problems, we recommend trying this at least for a little while to see if it helps. The probiotics in this are awesome.

Honestly, when we mixed it in water, this protein mix flavor wasn’t a huge hit, but blended into smoothies it worked great. That takes a little more work, but it’s also a good opportunity to add a real health kick to the kids’ diet.

What We Like:

  • No sugar, dairy, or soy
  • Vegan-friendly
  • Contains probiotics for easy digestion
  • Organic and non-GMO

Even the pickiest eater will love the double chocolate flavor all while getting the protein their growing body needs.

One scoop of this powder is packed with 21 grams of protein and only 1 gram of sugar per serving.  

We don’t love that it does contain some artificial flavor, but for the extra picky eater, this chocolate taste might win them over.

What We Like:

  • Packed with protein in one scoop
  • Tasty chocolate flavor kids will love
  • Only 1 gram of sugar

What We Don’t Like:

  • Contains artificial flavor

Looking to add more fiber as well as protein into your child’s diet? Then this protein powder might be the right one for your child.  Nutiva Hemp Protein Powder contains 12 grams of fiber and 11 grams of protein per serving.

This is another 1-ingredient wonder, as this protein powder contains no sugar, no preservatives, and no sweetener.  Just organic hemp protein. It is also high in zinc, magnesium, and iron.

We all thought it was a bit gritty, but it tasted okay. If your child needs more fiber and you want to go plant-based, this might be a really good pick.

Our only suggestion is to mix well.  The blender was necessary for mixing to avoid the potentially gritty texture.

What We Like:

  • Hempseed is sustainably farmed
  • High in fiber
  • Contains zinc, magnesium, and iron
  • Dairy and sugar-free
  • Can be added to hot and cold foods and drinks

Just one scoop of this protein powder has 18 grams of plant-based protein.  The protein blend consists of pea protein, hemp protein, and goji berry. 

It contains no sugar but does contain stevia extract for a touch of sweetness. Our kids liked the flavor of this one pretty well. It mixed well in dairy and non-dairy milk, and was easy to mix into smoothies.

What We Like:

  • The plant-based protein blend is all-natural and organic
  • Taste great in drinks and smoothies
  • No sugar or additives
  • Vegan- and vegetarian-friendly

This is another whey protein that sticks to only two ingredients: whey protein and sunflower lecithin.  The whey comes from pasture-raised grass-fed and hormone-free cows.

Each 1-scoop serving contains 25 grams of protein.  This protein is unflavored and very versatile and can be put in everything— smoothies, oatmeal, cookies, pancakes, and more.

We felt this protein powder was really good, and we love that it’s a clean whey protein. It was easy to use when cooking and also mixed into the kids’ chocolate milk easily.

What We Like:

  • Works well in virtually anything— pancakes, cookies, bars, and more
  • Packed with protein in just 1 scoop
  • No sugar, gluten, or GMOs

What We Don’t Like

10. Naked Casein

  • US FARMS ONLY: Naked Casein is brought...
  • COLD PROCESSED: Naked Casein is cold...
  • UNMATCHED NUTRITION: 26g of Protein, 2g...
  • BEST NIGHT-TIME RECOVERY: Casein protein...

You wouldn’t mind having this protein powder with your kids. Naked Casein contains one ingredient, micellar casein, which means no sugar and no artificial anything.

This casein in this protein powder comes from a farm in the United States. It contains no hormones and is soy-, gluten- and GMO-free. 

The taste is neutral and worked great when blended into smoothies, but don’t try serving this up in the water. We made that mistake. It was chalky and gross and we had a rough time getting the kids to try it again in milk.

It mixes well into smoothies and baked goods (kids gobbled them up and never knew) and provides a whopping 26 grams of protein per serving, which is 2 scoops – more than kids need, so cut it in half or less.

What We Like:

  • Only 1 ingredient
  • Serving size can be easily halved
  • Non-GMO and gluten- and soy-free

What We Don’t Like:

  • Expensive
  • Chalky taste and texture, so it’s best when mixed into recipes or smoothies

Frequently Asked Questions

Q: Can my child have too much protein?

A: Yes! Too much protein in your child’s body can make their kidneys work overtime and potentially make kids dehydrated.  If using a protein powder supplement for your child, be sure not to give them too much and stay within the recommended range of protein which as previously mentioned is 1 gram of protein for every 2.2 kg of body weight.

Q: My child doesn’t like shakes or smoothies.  What else can I put protein powder in?

A:  While a go-to for protein powder is to make a protein shake or smoothie, most protein powders are versatile enough to add to many more things! Here are some ideas:

  • Add a scoop to your child’s yogurt or pudding.
  • Add it to waffle or pancake batter.
  • Make protein balls. (Here’s a recipe!)
  • Add a scoop to cookie or muffin batter for protein-powered treats!
  • Mix into your child’s oatmeal.

Q: At what age can kids have protein powder?

A: Kids aged 4-13 may have small amounts of protein powder, though most don’t need it if they’re eating a balanced diet, especially one that includes dairy and lean meat. Be sure to not give them too much, because it can be hard on their bodies.
