One of the true heroes of the gym is actually what you bring with you. No, we’re not talking about attitude or determination. This isn’t a motivational poster.

We’re talking about your protein powder. In fact, the best source of powerful muscle-building growth comes from casein protein.

You’re probably wondering what casein protein does? Fair question. And what is casein protein good for?

First off, it’s the highest quality of any protein sources you can find. It provides your body with a steady stream of amino acids to build muscle mass, increase fat loss, and improve your metabolic rate.

That’s pretty good all from a glass of milk. Yes, milk is one of the most common sources of casein protein, but we’ll get into that later on.

If you’re into bodybuilding or you just generally want to lose weight and promote good muscle growth, look no further than this power-packed punch of casein protein.

Casein Protein Shakes

One search online for best casein protein product recommendations yields over 20,000,000 results. Yikes! How are you supposed to responsibly decide which is the best casein protein?

We’ve done our best to give you some of the varieties that we prefer and have a great taste as well. We’ve tested vanilla casein protein, chocolate casein protein powder, and have even come across caramel, mint, and peanut butter casein protein powders. Yum!

But let’s see which ranks the highest in our opinion.

We like them for protein quality, we like them for low carb diets, and we like them for pure flavour.

Many of the testers felt they weren’t even eating a protein bar because it tasted so good and natural. The caramel flavour was just one option, with almost a dozen other varieties to try if we ever got bored.

The bar also gave us the most casein protein per bite, almost 23g in a single bar. That’s on par with some of the protein powders we favour as well.

And with reduced sugar and carbs, we’re pretty sure you won’t feel guilty chowing one of these down at 3pm on a slow afternoon. Get that benefit of a slow-acting casein protein in a bar that doesn’t even feel like you’re making a healthy choice.

Casein Protein Bars

If you can’t manage to drink a smoothie in one gulp, or you just don’t have the time to measure it all out and mix it up, we still have something to help you out.

You can still choose a casein protein source, offering you the same benefits and features as a powder, but all in a convenient bar form.

We’ve included our best product recommendations for casein protein bars that you can enjoy on the go.

Just a word about protein bars. The majority of protein bars use some form of milk proteins in their makeup, which does include a mixture of casein and whey.

This does make for an effective, powerful combination that is sure to power you through your day. You still get the slow-release benefit of a casein protein.

Casein Protein Benefits

We touched on it earlier, but let us take a moment to expand on the casein protein benefits you’re going to love.

First off, casein protein is just one of the protein powders that affect muscle growth and mass retention.

Its first benefit is that casein acts incredibly slowly. It works to release those amino acids your muscles are craving in a slow 8-hour release that provides benefits long after you’ve put down the last weight.  It digests slowly and acts slowly, a good partner for whey, the other milk protein that acts quickly on your muscle mass.

Second, it boosts your metabolic rate, increasing the speed at which your body burns energy. Studies show that people with a higher calcium intake (calcium caseinate being the form of casein we’re eating) experience faster energy burn and increasing fat loss.

We also love that casein acts to increase the protein synthesis of your muscles. When you work to muscle failure, you’re triggering the body to rebuild the tissue. When you supplement casein protein, you’re boosting the source of protein synthesis; amino acids. Take an additional amino acid or two, and your body builds stronger bigger muscles.

Casein Protein Side Effects

Your intake should be monitored and regulated by the amount of activity you do. If you’re higher performing athlete, you require more casein protein to experience results.

But casein does have its side effects. Watch for symptoms of excessive usage which include reduced immune response, bloating, or heartburn.

You should, as a guide, try to aim for 1g/kg of body mass intake.

Please consult a physician before attempting to create a supplement schedule for your body.

Natural Casein Protein

As we mentioned earlier, casein is the naturally occurring protein found in milk.

Ever heard of curds and whey? Casein is the ‘curds’ of milk. In fact, it makes up over 80% of the protein found in milk. It’s also found in many other milk products like cheese, yoghurt and natural butter.

The casein is in its highest concentration in cottage cheese and natural ‘Greek-style’ yoghurt.

In fact, one of the best ways to get casein to act in your body is to eat a milk-product right before bed, allowing the slow-acting proteins to release during the night while you rest your muscles.

Consuming one glass of milk should give you 7-8g of casein, which is why it’s always beneficial to use a supplement if you’re actively looking to boost your casein intake. If you want to meet the recommended amount, you’d have to consume 12 glasses of milk each day just to meet your high-performance needs.

If you want to see the benefits of taking a casein protein supplement, try one of the best casein protein powders that we’ve listed above. You should see results quickly and you’ll enjoy the long-lasting effects that casein protein has on your body.
