10 Best Casein Protein 2018: Slow Release Amino Acid Boosters?

The Best Casein Protein Of 2018

Building muscle can prove to be a somewhat difficult task if you don’t have the right equipment. The same could be said for having the right supplements. Many who seek to build muscles often turn to casein for its ability to provide constant fuel at a slow rate, which is needed for muscle building.

Casein protein comes from cow’s milk, which is also true of whey protein. The major difference between the two is that casein is slow-digesting while whey is fast-digesting. They are both an excellent source of essential amino acids.

Because casein protein is slow-digesting, the fuel that it supplies is perfect for recovering from extreme workouts and rebuilding muscle fibers.

As more and more companies start using casein protein in their supplements designed for working out, it’s quickly becoming more difficult to choose the right supplement for yourself. Luckily for you, we have done this job ahead of time and constructed a list of some products which use casein in their formula and which might be exactly what you are looking for.

Remember, this list isn’t following any specific order. All of the products are listed randomly:

1. Naked Casein

There are very few supplements out there that truly use the less is more approach when it comes to helping you with bulking up. Naked Casein is one of those products, and it delivers as much casein as possible without many additional ingredients.

This formula is lacking in many ingredients that some use to make the product a bit easier to consume. One of those ingredients which are frequently used is some sort of emulsifying agent, which is basically there to help give the shakes that you make with the product a bit of a smoother texture and thus make consumption easier.

Naked Casein decided to stick as close as possible to just casein and nothing else. Because of this, there aren’t any emulsifying agents present in this product. This makes turning it into a supplement shake pretty difficult without the use of something like a blender. So keep that in mind if you do decide to go with this specific supplement.

If you are one of those people who are choosing to make your own meal replacement, then adding your own emulsifier to this casein product shouldn’t be an issue and will most likely result in a very good shake. Otherwise, this supplement is pretty much designed for those who seek something that is pretty much pure casein protein.

2. Optimum Nutrition Gold Standard Casein

If you are the type of person that already knows the effects of casein protein and take it frequently, then the huge four-pound tub of Optimum Nutrition Gold Standard Casein is a good choice. This product comes in a micro powder form that makes blending the casein protein in a drink or a shake pretty easy.

Unlike other pure casein products, this one contains some emulsifiers which make it even better for blending and mixing. Additionally, there are both natural and artificial flavors present in the formula that give it a specific type of taste.

If you are someone who is seeking pure casein products, then this one is most likely not for you. However, if you want a supplement which is easy to mix and has a specific taste to it, then Optimum Nutrition Gold Standard Casein is an excellent choice.

3. Cellucor COR-Performance Casein

Cellucor isn’t one of those lesser known companies. They have been around in the supplement world for quite some time. As expected, their formula for casein protein supplements is somewhat predictable.

You get the standard of both natural and artificial sweeteners, which give this supplement its unique taste, then the addition of a few anti-caking ingredients and a couple of emulsifying agents, resulting in a solid product that is easy to mix and blend and can be stored for a long time.

While ensuring that your protein is easy to mix and consume is definitely on some people’s list of benefits, others who are trying to avoid all the extra ingredients might not find this to be a suitable supplement for them.

4. BSN Syntha-6

Unlike the more traditional casein supplements which try to stick to just one protein, BSN’s Syntha-6 is a powder which is designed to be a meal replacement product more so than just a casein protein supplement. This product is attempting to take advantage of both whey and casein proteins to deliver the boost you need to gain as much mass as possible throughout your workouts.

This formula contains whey protein, casein protein, milk, and a plethora of sweeteners and flavoring agents. Additionally, there is the inclusion of medium chain triglycerides, or MCT oils, which are known for their numerous benefits, including improved cognitive function and significant improvements in weight management.

While this mix of ingredients is somewhat impressive and should definitely offer more than enough benefits, if you are a purist this isn’t the product for you. Otherwise, there is no reason to give this supplement a shot.

5. EAS Whey + Casein

We always try to give each product the benefit of the doubt, but after looking closely at the content of EAS Whey + Casein it has become really difficult to offer it as a good source of casein protein. While this supplement might be beneficial in other ways, since it does offer whey and soy proteins, the only casein source that we have come across is through the milk protein which is being used in the blend.

All of this leads us to believe that the quantity of actual casein in this supplement is rather low. Your end result is emulsifiers with sweeteners and pretty much all whey protein. So if you are looking to take advantage of casein protein benefits, we doubt you will see any within this supplement.

6. BulkSupplements Casein

We love products that get straight to the point without beating around the bush. That’s exactly what BulkSupplements does with this incredible formula. There are two simple ingredients. The star of the show, casein in powdered form, is at the core of the blend, with the addition of something to help you mix this stuff with water, soy lecithin, as an emulsifier. That’s all there is. The bag comes in sizes of up to 11 pounds and is super easy to use.

If you are looking for just casein protein, then this is your best bet. However, if you have a hard time accepting the somewhat chalky and often chunky taste of protein, then you might want to move on to another product. Also, while soy lecithin will definitely help this stuff mix well with water, you will still have to put some work into it.

7. Ascent Native Fuel Casein

By this time, you most likely have realized that there are two types of casein protein supplements: those that are hard to mix and don’t taste very good, and those that are easy to mix with a ton of artificial flavoring. Luckily, one company decided to meet you halfway between these two different types. Ascent Native Fuel Casein is the perfect choice for those who want something that tastes great, is easy to mix, and doesn’t contain weird unknown ingredients.

One of the key tasting elements used in their formulas is cocoa powder which, with the addition of a few natural flavors and some calorie-free sweeteners like monk fruit extract and stevia, leaves most other supplements in the dust. Add a few emulsifiers to ensure proper blending when liquid is introduced and you’ve got yourself a tasty, easy to make supplement which does an excellent job avoiding unnecessary ingredients.

8. Dymatize Elite Casein

This is another casein protein supplement that was designed with taste in mind. Dymatize has decided to use cocoa powder as well as a few natural ingredients to make their supplement taste pretty good. Add a few emulsifiers from sunflower and soy and you’ve got a drink or a shake which is easy to mix and has a superior taste.

Instead of the more natural sweeteners, Dymatize used sucralose in their product. Some might be reluctant to use a supplement with artificial sweeteners, but this is still a very good choice for a casein protein supplement. It’s definitely worth a try.

9. MuscleTech Platinum Casein

If taste and blending quality are what you are after, then MuscleTech Platinum Casein is definitely a great choice for you. Just keep in mind that all of this was accomplished with a huge load of different ingredients like sweeteners, coloring agents, anti-caking compounds, and a ton of artificial flavoring.

If you don’t mind taking all of these extra ingredients and sacrificing staying natural when it comes to supplements, then this supplement isn’t a big deal and will offer one of the best tastes and easy blending. At the same time, try to remember that some other supplements can also accomplish similar results without using every known ingredient under the sun.

10. Six Star Casein Protein

If you’re looking for a meal replacement, you’ve come to the right place. While Six Star Casein Protein does present itself as a casein protein powder, the ingredients used in its formula make us think somewhat otherwise.

One clear case of evidence of this is the use of maltodextrin. This wonderful ingredient is actually a complex carbohydrate which effectively turns this labeled protein powder into much more than just that. The addition of this complex carbohydrate pretty much requires you to use plenty of artificial and natural flavoring as well as sweeteners, which comes in the form of sucralose in this supplement.

Milk protein isolate is the source of the casein used in this blend, which makes it a secondary ingredient, not a primary one. So calling this product a casein protein supplement is somewhat difficult. We think of it as more of a meal replacement or mass bulking product. Since the casein comes from milk protein isolate, you won’t be getting many benefits that casein usually has to offer.

Casein Side Effects, Benefits, and Dosage

As mentioned earlier, casein protein provides numerous benefits for your body. It’s able to help you heal quickly after every workout and also build muscles by providing the necessary protein needed to rebuild muscle fibers.

The best part is that it’s digested slowly, which means that the protein is being introduced into your body at a steady rate, thus providing a constant supply of the vital building block for your muscles. It’s often far more effective than whey protein.


The main differences between whey protein and casein protein and the way they affect our body were measured by a group of researchers who did a study 2010. The key difference they were looking to find out was the amount of amino acids in the blood of subjects who used casein protein supplements versus whey protein supplements when compared to a control group who didn’t use any supplements.

All three groups drank their respective shake after an identical weight lifting workout. The conclusion determined that branched-chain amino acids rose the quickest in the whey protein group but insulin was also rising pretty quickly in that group, as well. Otherwise, there weren’t any major differences between the two protein groups.

This conclusion suggests that both proteins are able to deliver similar results. However, whey is rapidly absorbed which can often cause spikes in the amino acids and insulin in the blood post-workout.

While this initial boost of amino acids could a be a good thing if you are looking to sorts of jump start your recovery process, the constant and steady supply of casein might be a better alternative since there is a constant delivery of the muscle building blocks needed to regenerate muscle mass.

Another study suggests further differences between whey and casein. This one was done in 2007 to determine the effects that each protein has on the levels of hunger and amino acid levels in the blood after consumption.

As far as levels of amino acids go, the results were very similar to previously mentioned research: spikes in amino acids and insulin. Since this was the case, it would be rational to assume that the quicker absorbed protein would leave the participants of the study feeling hungrier when using whey protein versus casein protein.

However, the levels of hunger seemed closer to resembling those after eating a full meal amongst whey protein users when compared to casein users. This means that whey protein actually has further and deeper reactions on hormonal levels in our body.

Additional research was done to compare the effectiveness of casein amongst older and younger men. This specific research measured the response older men with an average age of 74 had on consuming whey protein along with older men who consumed casein protein.

The results showed that the total muscle mass gained was higher amongst those who used whey protein rather than casein protein. This concludes that perhaps older men can’t digest casein as easily as younger men, or perhaps it might also indicate that whey protein is better at jump-starting the synthesis process of muscles then casein protein.

Possible Side Effects

Since the majority of the casein protein which is used in casein supplements comes from cow’s milk, there is pretty much no known side effects profile associated with casein.

Obviously, if you have allergies to milk then you should probably stay away from all milk-based protein products like casein and whey. But even those who are lactose intolerant are usually completely fine with using casein products since the content of lactose in these supplements is generally very low.

If for some reason you do start experiencing bloating, gas, or discomfort in the gut, you should try to substitute your casein protein supplement with something like a vegan protein powder and see if the discomfort goes away. After the substitution, if the issues have resolved then chances are you have severe milk allergies or are highly lactose intolerant. In this case, casein or any milk-based protein is off the table.


It’s tough to determine exactly how much casein protein you should be consuming. One factor is endurance training. Those of us who are simply regulars at the gym don’t need nearly as much casein as those who are seeking to improve their endurance performance while undergoing strength training.

Research has shown that strength training increases the demand for protein to about 1.7 grams per every 2.2 pounds of body mass daily. So a strength training athlete who weighs around 200 pounds should take about 160 grams of protein per day.

People who don’t move as much could also benefit from casein but in a much lower dosage. Sedentary people need only about 1 gram of protein per 2.2 pounds of body mass.

Keep in mind that even though casein is absorbed at a much slower rate than other proteins, it’s still digested within a few hours. This is why it’s important to spread out your intake of casein throughout the day, especially if you are planning on working out more than once per day.

10 Best Casein Protein 2018 Summary

Casein is a fantastic protein and using it to gain muscle mass will give you a huge advantage in traditional weightlifting. While whey can also produce similar effect, keep in mind that casein is more slowly digested and often is able to deliver the protein at a steady rate so that you always have enough building blocks for your muscle recovery.

If you are an older male, it might be more beneficial for you to use whey protein over casein protein since research points to there being higher difficulty in absorbing casein for older males. Try both and determine which is best for your needs.

Taking protein supplements can surely give you the edge you are looking for, but nothing will substitute your diet and the nutrients you need every day to synthesize your muscles properly. Always remember to ensure you are following a good diet for the type of training you are planning on doing.

As with any supplement, consulting with your doctor is vital. They are able to determine the best course of action for you judging from your past medical history and current medication profile.

Casein protein might not be the best choice for you due to possible complications that only your doctor might be able to determine. They have the knowledge which you should take advantage of to determine the best course of action for your individual needs.

Remember that everybody is different and unique in their own way. Some supplements might have a better effect on some people while others might work best for other people. You are no exception, and choosing the right supplement might take time, but as long as you follow the given information, we are sure you will find the right product for you.
