Hi, I am Travis. My main focus in life is to understand training better and help others get better results too. I used to be about the least fit kid in school and would always be last to get picked for a team. It wasn't for a lack of trying, but all my efforts just lead to injuries

For years, I had completely given up on ever getting in shape. Then I began to use my brain before using my muscles. I read every popular book on exercise, and began to structure my training.

With the right training methods, and the right machines, I was able to rebuild my body from the ground up.

According to science, I would never be able to walk pain-free again. And I would never be able to do 20 pull-ups with the injuries to my rotator cuff. But they were al wrong.

This site is where you can find all my tips and recommendations.

Which of the Best Casein protein powders is right for you?

To better understand casein protein and why you want to use it for your next protein shake, it is best to start by answering a few fundamental questions. Getting the more basic matters out of the way lends greater value to any particular matters of fact regarding product comparisons.

When all is said and done, you should know which product is the best Casein protein powder for you. We might as well start with answering the question of what casein supplements are and what they do? After that, it should be easy enough to delve slightly deeper into the benefits of casein protein.

Anyone can appreciate a little side by side information, so we can compare casein vs. whey to liven things up. But, there are other issues to address as well. For example, what are the other uses and more interesting attributes? Are they good for weight loss or women? The list of questions goes on and on. So, let’s get started.

What is Casein protein, and what does it do?

So, just what is this casein protein, and what does it do exactly? A good way to answer such a question is to say that casein comes from cow’s milk. As a matter of fact, it constitutes the major part, about 80 percent, of any amount of milk you consume. The other 20 percent is the whey protein, which exists in the form of a liquid.

As such, this protein is present in every dairy product on the market. The extracting process involved with yielding casein from cow’s milk involves a little chemistry these days, and it’s easy initiated through the use of an enzyme named Chymosin. The cow’s milk is exposed to the enzyme, which causes it to clot into casein.

After that physical transformation, the protein is further refined and processed until the desired substance results. When it comes to casein, there is more than one form for you to choose from. Namely, you can go with the micellar or calcium form.

The best powder form is not exactly a black or white issue. If you want to absorb the protein more slowly into your body, then go for the raw, micellar casein protein. If you would rather intake a more digestion-friendly take on the protein, go with the calcium form. But either way, you go, the results will be good because casein is a complete protein with all the essential amino acids a body needs for repair, growth, and other life-sustaining functions.

What are the benefits of Casein protein?

As hinted to earlier, casein does many beneficial things for the body and can be used for nutrition supplement because it doesn’t need to be taken with any other protein to do its job.

  • Slow digesting protein for a long-lasting stream of amino acids to the muscles
  • Complete set of amino acids

Each of these benefits is essential to the body, and some of them are really non-negotiables depending on your particular lifestyle habits. Starting from the outside in, casein increases muscle mass all by itself and can yield double the results when paired with regular exercise.

Using this kind of supplement and working out regularly triples fat loss. Not only does the protein increase muscle mass, but it also decreases to amount of muscle breakdown during prolonged periods without nutrition.

Strong, long-lasting muscles are not the only surface rewards of consuming casein protein, as it protects the enamel of teeth from cavities, sensitivity, and decay.

Are there any more benefits of Casein protein?

Going a little deeper, casein powders do a lot more than make a person look and feel good from steady consumption.

For example, the immune system sees a bolster in its activity due to the growth of good bacteria and antibodies brought upon by the presence of casein. This protein does more than help the body by raising immune defenses; it lowers the levels of dangerous substances in the body.

Supplementing with casein lowers the absorption of triglycerides after a fatty meal. On an even more significant level, casein protein has antioxidant properties that cannot be ignored or denied because of its importance to health. This is one of the reasons we really like supplements that include micellar casein protein powder.

The antioxidants pepsin and trypsin are known to protect the body from free radicals that cause diseases like cancer, arthritis, and atherosclerosis.

With all the talk of fat loss, you may have asked yourself, how does it happen? It happens due to a rise in your metabolic rate while you sleep when the body does some of its best growth and repair functions.

Casein vs. Whey protein

Before we can compare casein protein to whey, there have to be a few points mentioned. For one, whey protein is still the go-to nutrient to build big muscles within a noticeably short amount of time. However, it also has a bit of a reputation for delivering results that last a noticeably short amount of time.

If incorporated into a diet correctly, whey yield lasting results. With casein, the “heavy lifting” of absorption rather happens on its own. The muscle growth from casein lasts longer because of its slower digestion rate and slow release in the bloodstream.

Casein's consistency has a gel-like quality to it that some people might describe as an acquired taste. Should the truth be told, you get the best results from a mixture of the two with an extra serving of casein shortly before calling it a night and going to sleep. While you sleep, the casein powder will ensure a continuous slow release of amino acids that helps your muscles recover and grow.

Casein protein for women

casein protein supplements for women

When it comes to women and dietary supplements, it’s a bit of a challenge to say which product is the best casein protein for women. In just about every case, casein provides the perfect solution for those who put effort into their exercise regime but do not see desired results.

It is not just about seeing muscle growth. Without the needed protein intake, a woman may be unwittingly causing needless damage to the body while exercising regularly. A steady source of slow-release protein like casein makes sure that everything remains on the level. Of course, casein works for those women who have weight loss for a fitness goal. However, deciding which product on the market is the best casein protein for women may be subjective. Its effectiveness is just about guaranteed.

Casein protein for weight loss

So, you might be asking yourself just how does casein protein aid in weight loss. The answer is quite simple. In protein powder, casein delivers very low amounts of calories as a source of nutrition. Fewer calories in the body translate to weight loss.

The best casein protein for weight loss has the least calories in theory. Certainly, any protein powder can make this claim and deliver results. But in the case of casein protein, the supplement's sheer thickness makes it better for losing weight.

It lasts longer in the body so that you can experience less hunger throughout the day. Less hunger means more control over eating habits and sticking to diets. The best casein protein for weight loss helps you stick to your diet.

Should I take casein protein before bed?

For the best results, the smartest time to make yourself a casein protein shake is right before going to bed. While we sleep, the body does most of its repair and growth; since casein can take up to 7 hours to fully be absorbed into the body, taking it before bed makes sense.

That doesn’t mean bedtime is the only time you should supplement the protein in your diet. There are plenty of times and occasions when you can snack on an appropriate amount of casein throughout the day. For example, you can enjoy serving a few hours before working out.

Or, you might keep a “mix kit” of bottled water and pre-measured scoops of casein handy for those times when you can’t take an official lunch break, but you don’t want to skip a meal.

How much Casein protein should I take?

So, we have covered the many benefits and ways to take casein.

However, we haven’t discussed just how much of the stuff you need to consume to see weight gain or loss results. Naturally, the specific answer to that question is subjective from user to user. On the other hand, there has to be some starting point or formula to follow for starters. The usual rate of consumption is 1 half or 2 grams per pound every day or as needed. For a guy or gal who weighs 160 pounds, the numbers range from 80 – 320 grams a day.

If you want to lose weight, consume less casein, and vice versa. Remember that protein shakes are methods to supplement diet needs. You have to calculate how much casein you consume in addition to the other calories in your diet.

If you want an easy place to start to feel comfortable making your adjustments as needed, take 1-2 scoops of 25-50 grams of powder 2-3 times a day.

Casein protein side effects and risks

As far as side effects of casein protein go, some people can experience bloating because of consumption. If you are otherwise healthy, this protein cannot hurt you.

However, people who live with kidney or liver disease should go easy on how much they digest. If you find yourself allergic to casein, try the hydrolyzed form, or avoid it altogether. It’s easier on the body.


Casein is a great supplement for athletes and people who want to give their body the best nutrition possible. The best casein protein powders provide a slow release of amino acids that help muscles grow and recover, especially when sleeping.

If you aren't using it already, you should give it a try. Many athletes have used it to break through their plateaus.
