Easy ways to Boost Protein in Smoothies naturally using ingredients that you already have on hand. Cheaper and healthier than protein powders, and they taste great! Try our Healthy Blueberry Cheesecake Smoothie and our delicious Green Smoothie for Beginners!
I started drinking protein smoothies several years ago when I worked through the exercise program P90X.
The program’s diet called for daily protein shakes, but since we were in the process of switching over to real food (and avoiding ingredients we couldn’t pronounce)…
I couldn’t bring myself to knowingly drink something with a completely unrecognizable ingredient list!
So I did my research, made lots of smoothies and wrote a book on making protein smoothies without adding protein powder, called High Protein No Powder.
I learned that it’s relatively easy to make protein smoothies, so long as you are strategic and intentional with the ingredients you use.
How can I add protein to my smoothies?
- Make sure every ingredient has protein. Many people will use water to make smoothies because it has zero calories, but guess what? It also has zero protein.
- Don’t overlook the protein in fruits and vegetables. Smoothies usually contain bananas because they are great at repairing and replenishing the body post workout, and they’re naturally sweet. One banana also contains 1.6g of protein! One cup of spinach contains nearly 1g of protein and kale contains 3g protein per cup!
- Boost the protein naturally. According to Harvard Medical School, the average sedentary person (someone who doesn’t exercise) needs just 0.8g of protein per kilogram of body weight. To figure this out for yourself, multiply your body weight in pounds by 0.36.
Note: Remember, this is only valid if you don’t exercise. Those who exercise regularly, are pregnant or require a high protein diet need to consume much more. And you’re not going to get what you need in a banana smoothie alone!
12 Natural Ways to Boost Protein in Smoothies
Although I included over 50 ways to add protein to smoothies in my book High Protein No Powder…
I want to share some easy ways to make high protein smoothie recipes using ingredients you might already have at home.
1. Cottage cheese
An unlikely choice I know, but there is 12.6 grams of protein in just ½ cup of cottage cheese!
This is one of the secret ingredients to many of my healthy smoothie recipes, including the Strawberry Cheesecake Smoothie, Orange Julius and the Mango Tango Smoothie.
If you’ve never heard of kefir before, think drinkable yogurt. It’s usually cow milk that has been fermented. You can find my full tutorial on making homemade dairy kefir HERE, as well as the health benefits of kefir HERE.
Kefir contains a whopping 10 grams of protein! Of all the choices of liquids to put in a smoothie, kefir is my top pick.
3. Collagen for Protein in Smoothies
You know how bone broth is so good for you? It’s because of the gelatin that is extracted from the bones when you cook them. Collagen is uncooked gelatin, and adding a scant tablespoon to a smoothie boosts the protein by 10 grams!
By itself, collagen is tasteless, odorless and dissolves without any issues. I add it daily to my green maca smoothie and love the benefits in my hair, skin and nails. It is important however, to buy quality collagen. I only use and recommend Perfect Supplements grass-fed hydrolyzed collagen.

4. Peanut Milk
You might be tempted to reach for almond milk, but that won’t get you the most protein per serving. In fact, of all the non-dairy milk alternatives, almond milk is in a 3-way tie for last place with coconut milk and rice milk.
On the other hand, peanut milk will give you 9 grams of protein in just a ½ cup! Peanut milk isn’t available commercially in many places, so your best bet is to make it yourself. This easy peanut milk recipe calls for just two ingredients – peanuts and water – and you can sweeten and/or flavor the nut milk however you’d like.
If you don’t want to go through the trouble of making peanut milk, how about just adding peanuts to the smoothie? You’ll be boosting the protein smoothie with 8 grams of protein for every 2 tablespoons you add!
For an extra treat, feel free to add a little cocoa powder! Shhh, I won’t tell anyone. 🙂
6. Animal milk is a great source of protein in smoothies
If your default liquid is cow milk, you might already know that one cup has 8 grams of protein. But did you know that:
- Goat milk has 9 grams of protein per cup?
- And sheep milk has a whopping 15 grams of protein per cup!
You probably don’t have easy access to a sheep, but definitely consider animal milk as the liquid in your protein smoothie.
7. Nut Butters add protein to smoothies
I’m certainly not trying to sound like a broken record, but it’s a fact that nuts contain a large amount of protein (and also healthy fats) and that’s why you keep seeing them on this list. Did you know that…
- Peanut butter has 8 grams in a 2 tablespoon serving?
- Almond butter is in second place with 6.7 grams in 2 tablespoons.
- Cashew butter is next with 5 grams of protein in 2 tablespoons.
You can make your own homemade nut butters following this tutorial.
8. Hemp Hearts
Hemp hearts are a superfood, high in omega fatty acids, but they’re also high in protein too! Add 2 tablespoons to your protein smoothie to boost the protein content by 6.7 grams.
If you don’t think eggs belong in a smoothie, you obviously haven’t tried my eggnog smoothie before. It’s the classic flavor of eggnog, except that it’s real food, super healthy and available year-round.
And oh yeah, it’s high in protein too. Just one egg has 6.3 grams of protein!
10. Chia Seeds
I have to confess that I’m personally not a big fan of chia seeds. They get gelatinous when they’re mixed with liquid, and it’s a texture that my palate does not care for.
But still, they are high in protein. 2 tablespoons carry 6 grams of protein, and will work in almost any smoothie thanks to their neutral flavor.
(Just be sure to have LOTS of liquid or you’re making smoothie jell-o. No bueno.)
11. Greek Yogurt
I bet you thought this would be higher up on the list, right? Greek yogurt is definitely a high ranking source for protein – 6 grams in just ½ cup – but this post proves that it’s not the only source.
In case you were wondering, plain yogurt did NOT make it to this list. It’s a “so-so” source of protein – 4.3 grams for ½ cup – but Greek yogurt will really give you the boost you’re looking for.
Also, you can save TONS of money by making your own yogurt. I use this easy yogurt tutorial and it’s never failed me, ever. Once you have a batch of homemade yogurt ready, you can turn it into Greek yogurt using the tutorial right here. Easy peasy!
12. White Beans
Before you balk at the fact that I’m suggesting you add beans to your protein smoothie, hear me out.
We use them to make brownies, and you love those, right?
We use them to make chocolate hummus, and you love that too, right?
So then trust me when I say adding a ¼ cup of beans to your smoothie WON’T ruin it and you won’t even notice they’re there! Besides…
- It’s an easy way to add 4.4 grams of protein to your smoothie. After comparing dry beans to canned beans, it turns out that dry beans are the better deal.
- Be sure to soak and de-gas the beans with this method first so you’re not dealing with the aftermath later in the day.
- Also, making a big batch of beans in the slow cooker at the start of the week makes it super easy to scoop out ¼ cup and add them to your morning smoothie.
Can I use Almond Milk in my Protein Smoothie?
If you would rather use almond milk, despite its lower protein content, definitely consider homemade almond milk from scratch. It’s super easy and you can avoid the additives and added sugars that most commercial non-dairy milks have.
Plus making your own non-dairy milks is a great way to cut back on your grocery budget. Making things from scratch when it’s worth it is one of the principles I teach in Grocery Budget Bootcamp.
Is a Protein Smoothie Healthy for Breakfast?
Of course! Having a protein smoothie, made of real food ingredients, is a perfect way to start the day!
In addition to the 12 ideas listed above, I found 38+ other ways to boost the protein in smoothies! I’ve included ALL of the options, including vegan, in my book High Protein No Powder.
