Casein Protein
The unique biochemical properties of casein allow it to form a gel or "clot" in the stomach, leading to a slower, more sustained release of essential amino acids compared to other proteins, making it an optimal choice for those seeking to support muscle synthesis and prevent muscle protein breakdown.
Additionally, casein protein powder provides a high amount of essential and non-essential amino acids, including substantial levels of the branched-chain amino acids (BCAAs) leucine, isoleucine, and valine, which are essential to muscle growth and recovery. Furthermore, it is rich in calcium, contributing to bone health and also featuring in the diets of individuals who are lactose intolerant, as it typically contains less lactose than other dairy products. Available in various flavors and forms, such as micellar casein or hydrolyzed casein, this protein powder can be easily incorporated into a balanced diet. However, it is always advisable to consult with a healthcare professional or a dietitian before starting any dietary supplement regimen.
