How Long Does Pre Workout Last In The Fridge? (Overnight?)

So, you’ve just bought your first tub of pre workout…

And you can’t wait to try it!

But how long does it last when mixed? And how do you store it correctly?

How Long Is Pre Workout Good For After Mixing?

This will depend on many factors, such as the temperature it’s being stored at, what ingredients are in the pre workout, etc.

(Pre workout stored in a warm environment will go off much faster!)

But as a rule of thumb, pre workout is good for 12 hours after mixing. If you leave it any longer, you increase the risk of bacteria growth which can give you a nasty bug.

Can You Put Pre Workout In The Fridge?

As long as your fridge is cool and dry (which it should be!), then there’s no issue with storing it in the fridge.

Some people prefer to store it in the fridge as they prefer their pre workout drink to be nice and cool.

Whereas others would rather use their valuable fridge space for healthy food like fresh meat and veg.

If given the choice, you should always prioritise keeping your food fresh rather than your pre workout cool.

So in my eyes, you should only keep your pre workout in the fridge if you have plenty of room.

Can You Leave Pre Workout Overnight?

Yes, you can leave pre workout overnight as long as you consume it within 12 hours of mixing.

Leaving it any time longer will increase the chances of it going off.

If you’re going to leave it overnight, you’re best off storing it in the fridge to ensure it’s as fresh as possible.

Where’s The Best Place To Store Pre Workout?

There isn’t really a ‘best place’ to store pre workout.

Anywhere that’s cool and dry will do the job as this will keep it fresh and free from moisture.

Can You Put Pre Workout In The Freezer?

If you have the space for it, then you can absolutely store your pre workout powder in the freezer!

In fact, I’d recommend this if you’re making a pre workout smoothie as it’ll mix much better with the other ingredients and be nice and cool.

But going back to what I said earlier, you should only do so if you have the space for it.

Never compromise proper storage of food for pre workout!

How Long Does Pre Workout Last When Stored Properly?

When stored in a cool and dry place, your pre workout can last a few years.

But when taken consistently, most pre workouts only last a couple of months anyways so you shouldn’t be too concerned as to how long it’ll last.

Can You Drink Pre Workout After Its Expiry Date?

Most pre workout powders have an expiration date of 2 years or so.

This basically means that after 2 years, the ingredients will start to lose their potency and so won’t be as effective.

So while drinking pre workout after its expiry date is unlikely to harm you, it may not be as effective as fresh pre workout.

But as I said earlier, your pre workout should only last a couple of months if taken consistently, so this shouldn’t be an issue for most people.

What Happens If You Don’t Store Pre Workout Correctly?

If you don’t store your pre workout properly, then it can lose its effectiveness a lot quicker.

It may also go clumpy which can make it hard to mix.

While it’s unlikely to go bad, you should store your pre workout correctly as advised in this article to avoid these common pitfalls.

How To Fix Clumpy Pre Workout

To answer this, we first need to know why pre workout goes clumpy.

Well, your pre workout can turn clumpy when there’s excessive moisture in the tub.

The best way to prevent your pre workout from going moist and clumpy is…

You guessed it.

Storing it in a dry and cool place!

Another effective way is to put a desiccant (silica packet) in the tub.

Many supplements come with a desiccant so it’s wise to keep these for your pre workout.

Now, as for fixing clumpy pre workout, one method that many people swear by is putting it in the freezer.

The cold temperature will help reduce moisture in the tub which should make it less clumpy.

Is Clumpy Pre Workout Bad?

Clumpy pre workout is quite common as most people simply don’t store their pre workout properly!

But if you’ve taken clumpy pre workout, then don’t worry – it’s very unlikely to harm you.

While it can be a bit of a pain to mix, it’s still considered safe and effective.

Can Pre Workout Go Moldy?

If you take the exact opposite advice from this article and store your pre workout in a warm and moist place (i.e., a steam room), then it may go moldy.

You see, mold loves heat and moisture.

But if you follow the advice in this article, then it’s extremely unlikely that your pre workout will go moldy.


In summary, pre workout is best kept in a cool and dry place.

This can be in your fridge, freezer, cupboard, or even garage.

It doesn’t really matter as long as it’s cool and dry!

Storing your pre workout incorrectly may result in clumpy pre workout.

While this is unlikely to harm you, it’s a bit of a pain to mix so should be avoided if possible.

That’s all for storing pre workout, but can you take pre workout twice a day? Or is pre workout natty?

Hope this helped!
