Best Casein Protein

Protein is an important food group. It plays a crucial role in muscle growth and repair and is also helpful during fat loss diets. Most people should eat between 1-2 grams of protein per kilogram of body weight per day, depending on their fitness and weight loss goals.

However, eating enough protein is not always easy. High protein foods almost always need cooking, and they can be expensive too. Protein supplements make getting enough protein a whole lot easier.

In this article, we’re going to review and reveal the 10 best casein protein supplements!

protein shake fitnessreviewsCasein is an interesting protein that compares favorably to whey – another popular protein supplement. Casein digests slowly, so it provides your body with a sustained stream of muscle-building amino acids. For this reason, casein is often called the nighttime protein. There are casein protein supplements to suit all needs and budgets, but it’s hard to know which one to buy with so many to choose from.

To save you from lots of mind-numbing research, we’ve tried and tested ten of the best. Whatever you need from a casein protein supplement, we’ve got the best product for you!

1. Bulksupplements

Bulksupplements specialize in producing simple but effective products that won’t break the bank. This unflavored casein protein powder is very budget-friendly and is about as pure and simple as a protein supplement can be.

Key Features

  • 25 grams of protein per serving
  • 106 calories
  • Less than one gram of carbohydrates and fat
  • Unflavored
  • No added ingredients

This unflavored protein powder contains nothing but calcium casein. It’s very low in calories and is all-but carb and fat-free. This is one of the cleanest, purest, and most cost-effective protein powders on review.

Pros

  • Easy to use
  • Very low in calories, carbs, and fat
  • An excellent source of amino acids
  • No artificial ingredients

Cons

  • Very bland flavor

Because it’s unflavored, this isn’t the most enjoyable protein powder to drink. Mixed with water, it’s all-but tasteless – just like diluted milk. That’s not an issue if you’re going to use it to make smoothies, but not so good if you want a tasty shake without adding other ingredients. However, it is one of the purest, cleanest casein protein powders on review.

  • Smooth, creamy texture

Cons

Key Information

Consider the following before buying or using casein protein powder:

What is casein protein?

Casein protein is made from milk. In fact, milk contains 80% casein protein. Like whey protein, casein is a by-product of cheese production. It’s made when enzymes are added to milk, making the casein turn from a liquid into a solid. Those solids are then collected, dried, and turned into a powder. Another word for casein is curds, as in curds and whey.

Casein is a very concentrated source of protein, and as well as being made into protein supplements, it’s also added to dairy products such as cottage cheese. Cottage cheese is an excellent source of casein protein. Casein contains all of the essential amino acids, which means, like meat and eggs, it is a complete protein.

Whole casein protein is vegetarian-friendly, but it is not suitable for vegans.

Casein vs. Whey Protein – what is the difference?

casein vs whey

Whey and casein are two of the most popular proteins around. They’re both made from milk, and they contain similar amounts of protein, but they are digested and absorbed at different rates.

Whey protein is digested very quickly, so think of it as a fast-acting protein. It’s ideal for use immediately after exercise when a quick hit of protein is useful for kick-starting the recovery process. To keep your muscles supplied with protein, you need to consume whey protein several times per day. That’s no problem during your waking hours, but not really practical at night.

Casein is a slower digesting protein. Because it’s slower acting, it provides your muscles with steady stream of amino acids rather than a big burst. Because of this, casein protein is perfect for nighttime use.

It delivers its amino acid payload gradually to ensure your muscles get a constant supply of nutritional building blocks. If you used whey at night, it would be over and done while your body was still trying to repair the day’s muscle damage.

To summarize, whey protein is fast-acting, ideal for daytime use, and especially useful after exercise. Casein is much slower acting and better for nighttime use.

What are the benefits of taking casein?

Your body needs protein for both structure and function. Structural proteins include things like your hair, skin, muscles, and bones, whereas functional proteins include enzymes, hormones, and antibodies.

Beyond these essential nutritional functions, dietary proteins, and especially casein, have several additional benefits:

StrengthMuscle growth and repair – exercise is catabolic, which means it causes muscle breakdown. To get stronger or build muscle, this damage needs to be repaired, a process called anabolism. Your body uses the amino acids in protein like a builder uses bricks. Protein is essential for muscle repair and growth.

satietySatiety – protein is very filling. Just a small serving can have a significant impact on your appetite. Hunger can derail almost any diet, leading to unplanned snacks and bigger meals. Consuming more protein can help ward off hunger, and taking casein before going to bed will prevent nighttime cravings.

body in shapeIncreased fat burning – protein has a high thermogenic effect. This means it boosts your metabolism, so you burn more calories, even at rest and while you sleep. Consuming casein protein before bed could help you lose fat faster.

Side effects

protein serving fitnessreviews

Casein protein is a very natural product. It’s made from milk in a process that involves no harmful chemicals. Providing it’s made from good quality milk, casein should be free from toxic substances like trace metals, hormones, and antibiotics. Remember, humans have been consuming casein for hundreds of years, albeit in the form of cheese curds.

That said, because it’s a dairy product, casein does contain lactose, which is a form of sugar. Some people are intolerant or allergic to lactose.

Lactose sensitivity can cause:

bloatingBloating

digestives upsetsDigestive upsets

rashesRashes

hivesHives

mucusExcess mucus production

Casein, and whey for that matter, contain less lactose than pure milk, so people who are only mildly lactose intolerant may not experience any unwanted side effects. But, if using casein protein makes you feel unwell, you should seek out a lactose-free alternative, such as rice, soy, hemp, or pea protein.

Bottom Line

Whether you are dieting for fat loss or trying to build muscle and gain strength, you need to consume adequate amounts of dietary protein. If you don’t, your progress will soon grind to a halt. Protein contains the building blocks your body needs for muscle repair and growth and also plays a crucial role in fat burning.

But, how do you make sure you get enough protein each and every day? After all, there is only so much chicken and so many eggs you can eat in a day!

Protein supplements like whey and casein are the easiest way to make sure you hit your daily protein quota. Quick and easy to prepare, just a shake or two a day is all you need. Use whey when you need a fast-acting protein and slow-digesting casein at night when a sustained supply of protein and amino acids are more useful.

Not sure which is the best casein protein? Don’t worry; we’ve got you covered. You’ll find the best product for your needs tested and reviewed in this article. From pure, unflavored products to protein powders that taste like your favorite milkshake, we’ve tried them all so that you can buy with confidence.
