Top 10 Best Casein Protein Supplements 2022

Many supplement companies claim to have the best Casein Protein of 2022. We have searched the market to find the best supplements in terms of both price and quality.

Unlike whey, casein  protein is made from milk curds. Whey is fast digesting, where as casein is digested slowly and so makes it ideal for some uses where whey would not be suitable. just like any other protein supplement, Casein supplements help the body repair and grow.  Casein is actually already found naturally in our diet from sources including milk and cheese.

Because it digests slowly, casein is ideal for when you are going to be away from food for a while or if you require a sustained release of amino acids. For this reason it is popular with body builders to use at night before going to bed. This way you can keep your muscles supplied with protein and amino acids all night long to allow them to grow and repair.

I like to mix some casein with whey in a post workout shake. This way you can increase your protein intake and provide your muscle with both a fast and slow digesting source of protein. You should look at a casein supplement if you are looking to put on muscle and working out a lot. During workouts your muscles break down.

To repair your body needs protein but if you have gone without protein for a bit the muscle-building process effectively halts Casein will keep protein flowing to your muscles for hours at a time. Meaning the muscle-building process will continue and you will be able to maximize on your workouts.

To find the best Casein Protein supplements on the market we looked at various factors including pricing, quality, reviews and taste. Take a look below at our favourite Casein supplements of 2022.

The Protein Works 100% Micellar Casein


The Protein Works has a growing reputation for high quality and affordable prices. With a huge range of high quality protein products available, 100% Micellar Casein is no exception. Each serving contains approximately 24.5 grams of protein, with this changing slightly depending on the flavour purchased.

There is also The Protein Works Aminogen Enzyme formula which helps the body absorb amino acids for muscle growth and repair. Casein protein is generally more expensive than whey and 1kg from The Protein Works costs £20.99 which is lower than many premium brands which offer similar protein values. There is a choice of five flavours available including chocolate mint brownie.

We like the chocolate silk which was enjoyable and tasted great. Mixability is also what you would expect from a premium quality protein and this makes a great shake for at night or any time you are not going to be consuming protein for a while. You can read our full review here.

That was our list for the best casein protein supplements on the market in 2017. Casein is great for increasing your protein and BCAA intake. Because casein is slow digesting, it is great at night but we also like to put some in a post workout shake.

To build muscle you should also be using whey protein after your workout to allow the protein to be digested instantly into your muscles. Building muscle takes dedication and motivation over an extended period of time but all the little steps add up to the end result.

It’s never too late to become what you might have been.
