Chunky Protein Shake: Why It Happens And How To Avoid It


You just got home from the gym. You are ready to replenish your body with a good ol’ protein shake. Then, the unthinkable happens. You created a chunky disaster.

The reason why your protein shakes come out chunky or lumpy can be from the following reasons. Usually, because you are not blending your protein powder correctly, not shaking long enough, using a freezing liquid, not using enough liquid, or your protein powder may be bad.

These are just a few reasons your protein powder clumps when making a protein shake. Below, I’ll dive more into detail on the causes and how to prevent clumping altogether to make a silky smooth shake.

Let’s Answer Why Is My Protein Shake Chunky

I don’t know if there is a worse feeling than getting excited to drink your protein shake only to be met with the weird texture of lumps and clumps as your protein shake flows down your throat.

Protein shakes usually get chunky because an error was made while mixing your protein powder. There are times when the protein powder is the cause of the problem. But it is highly likely that you are just mixing your protein powder incorrectly, which is causing the clumps.

Don’t get me wrong…

Like I said. Sometimes, the cause of the problem is the protein powder you are using.

Protein Powder With Scoop

Is It Your Protein Powder

Expired protein powder, low-quality powders, if you store your protein powder improperly and allow moisture to get in can cause clumping even though you’ve mixed your protein powder thoroughly.

But it’s likely your protein shake is clumping more because of mixing errors. (which I’ll tell you all about down below)

If you’re protein is expired and already past its due date. Then chuck that into the bin and grab yourself a new tub of protein powder.

Now let’s talk about…

Is It Normal For Protein Shakes to Have Chunks

It is perfectly normal for protein shakes to have some protein clumps.

When you mix protein powder, there can be a few things you are doing wrong, causing all the protein powder to form clumps in your protein shake.

What To Avoid To Avoid Clumps

These are some of the most common reasons why when you mix protein powder it creates a chunky protein shake

Not using a proper shaker bottle:

protein powder has a tendency to clump. (just like Nesquick chocolate milk powder)

So it’s important you use the right tools to mix protein powder.

Using too cold or very hot liquids:

When you add protein powder to very cold or very hot liquids, it can cause clumping

Using too little liquid:

If you don’t use enough water or milk when mixing your protein powder, it can come out chunky

Putting your protein powder first, then your liquid:

This might be the number one reason why protein powders end up clumpy. When you add powder first then you add liquid it almost always gives me a clumpy shake.

How To Prevent Protein Powder Clump

Now you know what to avoid when you mix protein powder together. Now let’s talk about how you can prevent clumps in your shaker bottle.

The following tips will point you in the right direction when it comes to making that silky-smooth consistency shake at home.

Shaker Bottle And Protein Powder

Using A Shaker Bottle For Protein Shakes

If you do not have your own shaker bottles. Then do yourself a favor right now. Get off of my blog and go order yourself one right away!

In order to prevent creating a chunky protein shake. The first thing you need to try out is: mixing protein powder with a shaker bottle.

Honestly, if you’ve been using a regular cup and then mixing your protein powder with a spoon or something, that drink is going to come out completely clumpy and full of chunks.

I learned this lesson early on with my first tub of protein powder.

Also shaker bottles are usually very inexpensive. Sometimes, supplement companies give out a free shaker cup when you buy a certain amount.

So be sure to look for deals like that if you do need one.

Now let’s talk about the next reason.

Close Up Of Temperature

Protein Powders And Temperature Of Liquid

This is something I also learned from personal experience. (Don’t worry, I appreciate you being here, so that’s why I got your back and am revealing all the good stuff.)

This might not be the case all the time. I’ve had whey protein powder that made a completely clump-free drink using very cold liquids.

However, I did notice that certain types of protein powders just have a very difficult time mixing with very cold liquids.

And in general, adding protein powder directly to very hot liquids will make them clumpy

I remember getting a protein isolate. And this product hated to be mixed with any cold water at all. I had to mix it with warm room temperature water. Then, after I mixed it thoroughly enough, I would pop it in the fridge to get cold.

That was the only way I could get this thing to be free of clumps.

So another tip is to add your protein powder to room temp, slightly cold or warm water if it has a tendency to form clumps with liquids with extreme temperatures.

Using A Blender

This is a surefire way to avoid a lumpy protein shake. I don’t think I’ve ever used a high-speed blender, and my drink came out chunky.

So if you don’t mind the extra dishes and hassle of using a blender, then I recommend you go this route. It will greatly reduce clumping with most protein powder supplements you’ll be using.

Plus, it gives you the opportunity to make a great-tasting protein smoothie instead. Try using milk, adding ice, and then your favorite fruits.

If your shake still comes out clumpy after using a blender. Then it might be because your protein powder is low quality, expired, or your protein powder container was not stored properly.

Liquid Ratio

Another reason why there might be some unwanted chunks in your drink is from not adding enough liquid to your shaker cup.

You want to add enough liquid. I personally try 8oz of fluid with 1 scoop of protein powder. This usually gives me pretty good results

Bonus tip: You can control the consistency of your shakes with the amount of liquid you use. So if you want a thicker, richer-tasting shake. Try to add less liquid

If you want something more watered down. Then, try to add a bit more liquid.

Liquid First, Then Protein Powder

This last point is probably the number one reason why I’ve had protein powder clumps in my shake.

I’ve noticed that if you decide to add powder as your first ingredient in your shaker cup. There is a higher chance that your drink will become clumpy. For some reason, protein has never mixed well whenever I add it first.

But if I add my liquid first, then add my scoop of protein. Then I get myself a complete protein shake without any remaining clumps.

So If you’ve been adding your powders first, then make sure you try this tip out and change the order of how you make your shakes.

I know it might sound dumb. But I believe the order truly matters from personal experience

How Do I Know If My Protein Is Bad

There are a few signs you can look for in your protein powder to see if it can be bad.

Signs of bad protein powder usually are a rancid smell, bitter taste, changes in color, and clumpy. It’s best to use protein powder before the expiration date listed on the tub. And be sure to look out for any of the signs I listed to ensure you are using fresh protein.

Those are just some of the signs you want to look for when trying to determine if your protein has gone bad. If in doubt, it’s always best to get yourself a fresh tub. Especially if the one you are thinking of using has been sitting for a very long time.

And when you do, get a new tub of protein. It’s essential you properly store your container. The last thing you want is for moisture to enter the tub and start wreaking havoc.

If your tub of protein is clumpy. Then that’s a pretty good sign that moisture was able to get in and start forming those clumps

Can I put anything in my shaker to reduce protein powder lumps?

Yes, the best thing you can put in your shaker cup is the blender ball.

Most shaker cups Should come with this already. But I know there are some brands that do not use the metal blender ball in their cups.

I’m sure you are familiar with the sound that these shaker bottles make. It’s that very distinct rattle and shake, almost like you were shaking an empty can of spray paint.

But I find that those spiral metal balls help mix my protein very well, giving me a smooth drink.

You can usually find these types of cups everywhere nowadays. I’ve even seen Walmart carry them in their nutrition section of the store.

From personal experience, those are the tips I’ve used to create smooth shakes without the clumps. I’ve also stayed with a certain brand of protein, so I know that if I end up making a shake with clumps. It’s most likely due to my mistake and not the brand of protein I am using.
