best casein protein

Casein protein has been used for years as a supplement for natural protein. A lot of bodybuilders and athletes rely on casein protein to build their muscles as well as to strengthen them. According to the FDA (The Food and Drug Administration), casein is a type of granular protein, which comes from skimmed milk and it is safe to be used as a protein supplement. Several researchers also suggested that casein protein helps to enhance the muscles of the legs, chest, and shoulders.

Casein protein is a slow digestive protein; for this reason, it is sometimes called a time-released protein. It provides amino acids which repair our muscle and also required for different muscle growth.  Compared to other types of proteins, casein protein has a prolonged absorption rate, and it releases amino acids in our body over a greater period of time. For this reason, many people find it more effective if they take this protein before bed. Read more to find out more about casein proteins, their usefulness, comparison with whey proteins and some of the best casein proteins in the market.

Slow Digestive Protein: What is Casein Protein?

Casein protein is a type of milk protein. There are two types of protein found in milk; whey and casein. The amount of amino acids casein protein contains is similar to the whey protein, but they are absorbed differently. This means casein offers all the necessary amino acids for your muscle growth as whey protein but acts in a slow manner. For this reason, this is particularly helpful for bodybuilders and athletes. Casein is also helpful to achieve synthesis protein rather than breaking them down. It helps to reduce fat and lactose but ensures a slow release of the required proteins.

Benefits of Casein to Human Health

Benefits of Casein to Human Health

The benefit of casein protein is that it slowly raises your blood amino acids, which is perfect for boosting protein level if taken for a longer period of time. As the absorption rate is slower,  it is recommended that you take this protein supplement before going to bed. The full array of benefits of casein protein is mentioned below:

  • Casein protein stays for a longer period of time in our body. Unlike other proteins, casein takes a longer time to digest and be absorbed by the body. For this reason, it offers a slow but long-lasting source of synthesis of protein, which helps to build up muscles.
  • Casein provides greater gains if added with other proteins. According to research, it has been found that while casein is taken with other forms of proteins, it yields quicker results than any other protein offers.
  • Casein also helps to increase metabolic rates, which help to lose fat and unnecessary lactose from our body.
  • For bodybuilders and athletes, strength is a significant factor. Casein provides more strength when compared to other proteins. A recent research shows that casein has anti-catabolic abilities which provide the double amount of strength to chest, shoulder, and legs than whey proteins.
  • Casein is also helpful for our dental health. It has the potential to prevent dental enamel erosion.

Whether you are a bodybuilder or an ordinary person, casein protein can be very fruitful and a healthy source of natural protein for your body. The next time you opt for a late night snack, go for a casein shake!

Different Types of Casein Protein

Casein is a dominant milk protein which is mostly found in skimmed milk. It is an excellent source of daily protein supplement.  Because of its slow but effective effect on muscle growth, casein has gained much popularity over time. There are three types of casein you will find. They are calcium caseinate, micellar casein and milk protein.

Calcium Caseinate

Calcium caseinate is generally extracted from insoluble milk portions and then purified using a chemical process. However, this type of protein is the lower quality of casein protein and are generally found as food ingredients.

Micellar Casein

Micellar CaseinMicellar Casein is the purest casein protein and definitely the best casein protein of the market. It is found in more natural form and this protein is digested and absorbed by the body more efficiently. This type of casein protein is anabolic because it’s a slow release protein that takes around six to seven hours to be released gradually. It promotes the releasing of crucial amino acids for different muscle growth, which includes arginine, glutamine and leucine. For bodybuilders and athletes, this is the best post workout supplement.

Milk Protein

milk protineMilk protein is not the purest form of casein protein as it contains both casein and whey protein. However, the ratio of casein protein is higher here. Of all the milk proteins, casein is 80% and whey protein is 20%. As milk protein is found at a lower price, it is ideally an excellent economical choice for different post-workout purposes. For its economic value, this can be the best casein protein source you can have.

Milk protein is also easily digestible. American Dietary Association suggests this protein to those who have weaker digestive systems.

Casein vs. Whey Protein: Which Is The Best Post Workout Supplement?

Casein vs. Whey Protein Which Is Best Post Workout SupplementCurrently, whey protein is the most popular and most used protein among bodybuilders and athletes. For both losing and gaining weights people take whey proteins.

Casein is another type of protein supplement which is gaining more popularity in recent times. For being the source of long-lasting and effective amino acids, this protein is also called the “the other protein powder.” It works as a protein supplement and provides required protein similar to whey. So, what makes the different types of protein?

  • One of the greatest factors is how these proteins are absorbed and how long it stays in the body system. Whey protein is absorbed faster and breaks down very easily.
  • On the other hand, casein protein is absorbed slowly and stays longer amount of time. Hence, casein is beneficial for fast muscle growth as well as preserving the lean body muscles.
  • Casein is better for building and strengthening muscles, a fat burner and better strength generator.
  • Whey protein is good for immune system and less helpful for fast muscle growth
  • For different milk proteins, casein contains about 80 percent while whey is only 20 percent
  • For workout purposes, casein hydrolysate provides more nutrients

Casein and whey both are highly important for our health. However, if we only talk about losing weight and strengthening muscles, casein is definitely superior and also the best post workout supplement. But for all-around purposes, a mixture of whey and casein produces the best result.
