Can you freeze smoothies that have protein powder in them?

Can you freeze smoothies that have protein in them? As you'll find out, the answer is simple. You'll learn about the benefits and how much protein you should have a day as well!

Should you freeze a smoothie that has protein powder blended through it?

The answer to this is yes, it’s completely fine!

Putting your smoothies in a freezer, then thawing a smoothie won’t change the nutrients or digestibility of the protein for you.

However, freezing and then microwaving the smoothie may cause some issues if that's the way you choose to defrost.

That being said, the flavour and texture may change too if you haven’t completely thawed your smoothie out properly.

So you have a few choices for thawing after freezing, you just have to find out what works for you.

You can microwave defrost, leave your smoothie in the fridge overnight until thawed or just take it out of the freezer and leave until thawed (but still chilled) to name a few.

Now that we’ve gotten that question out of the way, let’s look at why you'd want protein and look at some protein powders you can use in your smoothies.

A bit more information about protein

Protein is one of the essential macronutrients.

This means you need to get protein from your diet to thrive and survive.

We all know it as the athlete’s nutrient, this is because it assists in:

  • Helping with muscle growth and repair
  • Assists in improving injury recovery
  • Greater strength gains from training

Protein also has many other uses within your body, such as these:

  • Helps improve satiety
  • Supports building a healthy immune system
  • Assists in the production of hormones and enzymes within the body
  • Helps keeping bones, cartilage, skin, blood, hair and nails healthy

How much protein should you have each day?

There are a number of factors that can increase your body's protein needs, here's a few of them for you now.

  • The source of your protein, some are easier to digest than others
  • How well you digest, certain pharmaceutical medications like antacids can impair protein digestion
  • Whether you are an athlete or exercise
  • Are you recovering from an injury
  • In times of increased immune function

The Australian dietary guidelines recommend 0.84g/kg of protein daily for men and 0.75g/kg daily for Women, with an increase after 70 years of age.

To work your level out, simply multiply your weight by 0.84 or 0.75 for males and females respectively.

This means for a 60kg woman, this would work out to 45 grams of protein a day.

Organisations like CSIRO recommend a little higher at 25 to 30 grams of protein per meal, citing a few issues with the Australian guidelines.

Then, when we look at athletes and exercisers, we see higher needs again.

For example, a study on endurance athletes found they did best on 1.2g/kg of protein, while for those trying to put on muscle 1.5g/kg worked well. 


Consulting with a health practitioner who has studied nutrition can be really helpful in determining how much protein to eat and the different sources.

Protein powders

Here's a look at a some of the protein powders available for you.

We start off with the ones friendly to vegans, vegetarians and omnivores alike.

Hemp protein powder

Hemp seed products were recently made available for consumption in Australia

They used to be sold in health food stores with a label saying they were for use on the skin and not to be eaten.  

Hemp seeds also don’t contain any of the THC of marijuana.

And is you didn't know, THC is the active ingredient that's responsible for the high.

To make hemp protein, the oil is separated from the hemp seeds, and the remainder is sold as your protein powder.

Hemp protein has a very earthy taste that many people don’t like, so make sure you try it before you buy it (if you can).

Pea protein powder

Pea protein has been seen in many vegan protein powders for a few years now.

Unfortunately, it doesn’t contain all the essential amino acids, making it an incomplete protein.

But this doesn't make it it completely unsuitable as a way to boost your daily protein intake.

You just have to be aware to incorporate other proteins throughout your day.

This is if pea protein is your only protein source.

Vegetarians and omnivores protein only

Sorry vegans.

The next protein powders are animal based and not really suitable for you.

So without further ado, this next type of protein powders are only suitable for vegetarians and omnivores.

Whey protein powder

Whey protein is perhaps the most well-known protein powder and you’ll see it lining the shelves of most supplement stores in some form or another as there are many different variations.

Whey protein powder is manufactured from milk, the most common form coming from cow’s milk.

Although there are a few brands selling goat and even sheep’s whey.

If you do have a lactose intolerance beware, whey does contain some lactose (though much less than milk).

When you’re buying any type of whey protein, the best sources are from pasture-raised (grass-fed) cows with low temperature processing used to make the powder.

So make sure you read the nutritional labels before you buy.

Is that all the different types of protein powders?

Absolutely not.

In fact, there are probably too many protein powders to write about in this article because we would be here all day and through the night too!

You've also got the choice of rice, soy, egg white, whole egg, collagen and a bunch more I’m sure we've not even heard of yet.

If you are looking for a protein powder to use and you're not sure what you need, just ask at your local health store, chemist or similar.

Blending it all together

Now a little re-cap for you on what you've taken away by reading the above.

We know protein is necessary for a huge amount of bodily functions beyond just using it for athletic recovery and performance.

We've learnt that freezing a protein powder is fine and won’t change the potential benefits for you and this goes for pretty much all smoothie ingredients.

And, we also know now there are a bunch of protein powders you can choose from to use.

And that just about covers it!

There is one thing we haven't covered for you so far.

We have to let you know that it's Ok to put our Smoothie Cubes, Superfood Purée or even our Wholefoods Bars into your blender with your preferred protein powder, blend and then freeze.
