Best Casein Proteins in 2020 – Reviews

For those big gains and unrivaled recovery, many athletes turn to a quality Casein protein to give their body what it needs. Being able to refuel in a way that gives your muscles the ability to go again means you can get more days in the gym and you won’t ache when you push yourself.

The best Casein proteins are also good for those all-important new muscles since they are high in amino acids (B
CAA’s). Because you digest Casein slower than a lot of the other protein alternatives, it is better for recovery. This is only when you buy a reputable product with optimal dosages and ingredients. We have created the following list of the best Casein proteins so you end up packing your body with right nutrients.

Best Blend: OWN PWR Elite Series Protein Powder

With plenty of Casein powder among other proteins and benefits, this is a great all-rounder with plenty for recovery and those big muscle pumps. It is made up of 14.4 g of whey protein and 10.6 g of Casein protein. This means you aren’t getting as much Casein as other brands provide but you do get the benefits of Whey which include muscle growth and reduced inflammation.

With only 1 g of fat and 1 g of sugar in every serving it is great for anyone who wants to get shredded and it has also been tested for banned substances. When combined with strength training this is the ideal companion for building strong muscles. There is also 4.6 g of glutamine which is great for protein synthesis. Our only gripe is we would like a few more flavors but with vanilla ice cream in there as an option, we can’t complain too much.

Casein Protein Guide

When you want something to help your recovery overnight without the calories and all the BCAA’s and other benefits for your muscles, Casein protein is a great option. Even between meals, it is perfect because the slow absorption makes you less likely to reach for a snack as it gives you hours of recovery time. 

The better products are made from a quality source and give you the optimal amount of protein. Because not everyone knows enough about their supplements, we have created the following Casein protein buyer’s guide.

What To Look For In Casein Protein

High Protein 

In every scoop, you need to be getting a good amount of Casein protein or your muscles won’t get enough fuel to go again tomorrow. The best casein proteins tend to give you at least 24 g with 26 g being a good upper amount. 


With the right amount of amino acids in every scoop, your body can boost muscle growth. They can help to prepare your muscles for next time and have been found to not only keep fatigue at bay but promote weight loss. Because you want all these benefits as part of a workout regime, it is important to get a good dosage. 

Most Casein proteins tend to contain around 5 g of amino acids although it is not uncommon to find over 10 g in a scoop. 15 g a day tends to be a well-tolerated limit so anything close to that can be ideal.


Some supplements get a bad reputation based on their taste alone. Although many of us can tolerate a less than moreish shake there is something to be said for the brands that ensure theirs taste good. Look for a flavor you think you might like as a start or take a look at what other customers say.

Some products are made to be flavorless and just give you the pure Casein protein. This is fine if you can swig a scoop with water or add it to a shake.

Low Calories

If you are trying to put bulk on then this might not be as important but anyone keeping a close eye on the calorie content of everything they consume should look for a product that is low in calories. 

Benefits of Casein Protein

Slow Absorption

Because it takes longer to absorb, the benefits keep on working hard to allow your muscles to recover. As opposed to Whey protein that is quick to go through your system, Casein is ideal for taking at night or between meals. With a continual flow of protein and amino acids, your body is going to feel and look better. 

Muscle Growth 

Because it reduces muscle fatigue and protein breakdown, Casein protein is great for muscle growth. This is why it is the perfect accompaniment for strength training but even the likes of endurance athletes use it for their recovery. 


Because of its source, this should come as no surprise but Casein protein is high in calcium. This is great for maintaining healthy bones and teeth but let’s not forget that your muscles also need calcium to function properly. 

Protein Intake

If you don’t consume a tonne of protein then this might be the ingredient to help you make the most of what your body does consume. Sure, it will allow you to put the protein it provides to good use but Casein protein has been linked to promoting protein intake.

Fat Loss

Casein protein has links to fat loss but one thing that it can do is work as an appetite suppressant. When taking between meals it can replace an unhealthy snack.

Where Does Casein Come From?

It comes from the same place as whey protein – milk. Casein makes up 80% of milk protein with whey taking up the rest. It is a complete source of protein making it ideal for amino acid content and slow absorption.

Is Casein Protein Safe?

Although everyone is different, the Casein protein is well tolerated by most people. With one or two scoops a day (always check the recommended dosage) there should be no side effects unless you have any underlying health issues.

In some cases, it can cause bloating and if you have lactose intolerance then you should avoid it but for most people, it will be perfectly safe.

Casein Protein Vs Whey Protein

There is nothing wrong with consuming both if you get the dosages right and some products include a blend of both proteins. In terms of individual benefits, Casein protein is often considered preferable because it is absorbed slowly which means you get a longer recovery period and it can be taken at night. 

Whey tends to contain more BCAA’s but to minimize muscle fatigue, Casein is the better option. 

How Long Before Bed Should I Take Casein Protein?

There is no right or wrong time but a lot of people believe that taking Casein protein 10 – 30 minutes before bed can optimize the benefits. This gives you the slow absorption process as you rest so you wake up with the best chance of recovery.

What Is The Best Casein Protein?

People will argue on the individual benefits of different brands but taking brand favoritism aside for a second we found that OPTIMUM NUTRITION GOLD STANDARD 100% Micellar Casein Protein Powder provided the best combination of value, quality, 24 g of protein and a good amount of BCAA’s.

With appetite suppression and plenty of scoops in a tub it is not only going to last a long time but make a massive difference to how you look and feel the day after a big workout.

The other products on our list will also work wonders and if you want fewer calories or a slightly better flavor then other options might be better suited.
