What is Casein Protein?

Casein Protein is the most prominent protein found in milk. Casein Protein becomes a solid when split apart from milk. This solidity makes this protein more difficult to breakdown, allowing it to become a constant source of protein for muscles.

What’s the Difference Between Whey and Casein?

Whey vs Casein

Whey and Casein proteins both come from milk. Casein makes up around 80 percent of milk protein and Whey protein makes up 20%. Both protein types are beneficial to specific groups of exercisers.

Whey protein is the more popular protein because it is at a lower price than Casein and it is fast acting (within 20 minutes). This is super important for those that are wanting to bodybuild.

This group needs the muscles to recoup at a fast rate to build back the muscle at a faster rate and stronger. Whey is more likely to contain carbs and is the protein used in mass gainers.

Whey protein breaks down easier when mixing with milk or water to make a smoother protein allowing it to reach muscles at a faster rate.

Casein protein is less popular due to the higher price. The benefit of Casein protein is its ability to digest at a slower rate because it is more solid.

This protein benefits those who are eating at a deficit or fasting to lose weight. The Casein protein digests on average over 7 hours. This allows for those that are cutting back on calories to continue supply the muscle with constant protein so the muscles don’t start to breakdown due to lack of protein.

Casein is thicker as a protein shake and does not break down as easy in milk or water. Casein Protein is better to use when making a spread to put on a sandwich or make ice cream out of it.

Casein Protein Buying Guide

Micellar Casein vs Calcium Caseinate

Most types of Casein Protein are Micellar Protein. Micellar is the highest quality of Casein Protein because it is the least processed Casein Protein. Micellar protein is made when the milk is heated up and casein protein is separated from fat, sugar, and whey.

Even though it is a higher quality of protein, the Micellar is one of the thickest proteins. This makes it more difficult to digest and makes for a very thick protein shake.

Calcium Caseinate is one extra step in the processing process than Micellar Protein. After the Casein is separated from the rest of the milk, calcium is added to dry the protein. Calcium Caseinate still a slow-digesting protein compared to whey but it does not digest as slow as Micellar protein.

Check the Nutrition Label

Before buying any type of casein protein powder, check the nutrition label for grams of protein per serving and ingredients list.

The first place most go when buying protein is the grams of protein. Don’t be fooled by the grams of protein. It might be 2 scoops of protein instead of 1. Always check the serving size first.

Next check the ingredients list. You might be surprised by what ingredients are included in protein powders. A theory has circled around for years that companies use additional ingredients to fill up protein powder jugs to make more money. Look for a shortlist of ingredients and ingredients that you can pronounce.

The Casein product should have at least 20g of protein. Do not buy if it has less than 20g of protein!

If you’re planning to lose weight the calories should be around 100 – 150.

The carbs should be the last item to check on the Casein nutrition label. If you’re planning to add some serious muscle you will need to shoot for 20g of carbs. Those looking to lose weight need to stay around 5g to 10g of carbs.

Taste and Texture

Before we start the taste conversation, just know that the better the taste the more added sugar, fat, and natural sugar that is in the product.

Be careful when buying natural or unsweetened flavors of Casein because they will not taste as good as the others. When buying choose a smaller tub just in case you don’t like it.

If you made the mistake of buying a Casein protein powder you do not like, there is good news! There are certain products like powdered peanut butter or other protein powders that you can mix to make the protein taste better.

Casein products are naturally going to be thicker than whey proteins. This makes using as a protein shake difficult because you will have to mix it a lot to get the product to eventually thin out.

If you don’t like chunky protein shakes just know that Casein might not be the best choice for you.


The price is one of the first things we all look at when buying protein. Assumptions are made that the higher the price the more protein or the higher quality of protein. This is not always the case with protein.

That is why it is super important to check the nutrition label or the product description.

Casein mass gainers or Casein meal replacements will be higher priced but won’t provide more Casein or better quality Casein. These products will give more carbs or added nutritional supplements like vitamins and minerals.

A good rule of thumb for the price of Casein is 5 cents per gram. The higher-priced Casein should include enzymes or vitamins and minerals.

More protein powders


Casein protein is a great choice for those that need to lose weight while still needing enough protein to keep muscles defined.

With lower carb content and ability to keep the stomach full, casein will help those that struggling with overeating.

For those that struggle with the taste or need want to build bigger muscles, don’t give up on casein just yet.

If the taste is hard to get past, try mixing in other protein powders that taste good or mix in the powdered peanut butter mix. To keep those big muscles, mix whey and casein together for the best results.
