The Difference Between Whey And Casein Protein?

Whey and Casein are 2 of the most popular protein supplements on the market, and for good reason. They’re both high-quality, highly bioavailable, complete proteins that are particularly rich in branched – chain- amino acids (BCAAs), which makes them great for muscle growth and repair. However, despite both coming from dairy, there are distinct differences between them.

Both Whey and Casein are milk-based proteins derived from the cheese making process.

What’s The Difference Between Whey And Casein?

Whey Protein is digested pretty rapidly and Casein Protein is slow, gradually digested. Casein can take 5-7 hours to digest, whereas Whey can be digested within a couple hours.

Although both types of protein possess a high amount of amino acids per serving, Whey is considered to be more anabolic / muscle building, due to it’s ability to rapidly spike in the blood amino-acid levels, which are necessary to kick-start muscle protein synthesis. Casein, on the other hand, is often considered to be anticatabolic / good for preventing muscle breakdown, because it produces a steady stream of aminos over time that keeps breakdown at bay.

When Should I Take Protein?

Whey protein is best taken before, during, or after your workouts, because it hits your muscles with fuel quickly with minimal risk of GI distress. Casein, is best used before fasting, such as before bed or a long day of nonstop meetings, because the slow release of amino acids promotes fullness.
