What is Casein Protein?

Casein is a family of proteins that are found in milk/dairy products. These proteins make almost 80 per cent of the proteins found in milk and are an essential ingredient of cheese. Casein Protein is one of the two kinds of protein in milk, which are whey and casein. Casein has similar amino acids as in whey, except, the absorption rate is different. It is a blend of phosphoproteins of different molecular weights; it contains all of the nine essential amino acids the body needs to get from foods to build muscle and also contains carbohydrates, calcium and phosphorus.

Casein is a slow digesting protein, as it forms a gel like substance inside the stomach, then inturn releases amino acids and other nutrients at a very slow rate into the bloodstream, and that is why it is most ideal to be consumed at night before going to bed or as a meal replacement or while on a fast. However, there is another predigested form of casein called Casein Hydrolysate which gets absorbed quickly.

What are the Benefits of  Casein?

Despite having similar components as whey has, there’s only one thing which makes Casein Protein unique, its slow gradual release. And that’s why it has its own advantages such as –

  • Casein is a very versatile supplement if you use it during the day, it acts as a meal replacement and helps you lose weight and when you use it at night, you can aid in gaining muscles.
  • Casein keeps your hunger limited and improves your metabolic rate when the body is at rest. Casein releases amino acids slowly into the body which makes it ideal to be used before bed.
  • Casein is highly used during fasting so as to satiate the hunger and provide the nutrients to the body.
  • Apart from this, casein also has certain medical benefits. It has been said that casein if taken along with medicines which are meant to treat high blood pressure, may result in lowering the blood pressure to some extent.

Is Casein Protein safe to use? Does casein have any side effects?

Casein is likely safe for healthy individuals when taken orally. However, it can cause allergies to infants and young children. According to some researches, adults rarely experience side effects while taking casein for a longer period.

Some research in adults with type 2 diabetes has shown that casein hydrolysate protein improves insulin and glucose levels after a meal. Although, it’s not certain if taking casein protein for a longer period can be effective in controlling blood sugar levels.
