Micellar casein is an extremely slow digesting and rich protein source that continues to feed your muscles long after whey proteins have dropped off. In studies is has shown to offer a strong anti-catabolic effect. Casein takes anywhere from 5-7 hours to fully breakdown which keeps your body absorbing and utilizing the nutrients even while you sleep. People also use casein during the day to help stay full and to keep a constant supply of protein in your body to supply the muscles with proper nutrition for hours after drinking the shake.

sually blends comprise a mixture of whey protein and casein or milk protein. The theory behind the use of a protein blend is that different types of protein have different properties which makes them useful in different situation. For example, whey is normally used pre or post-workout whereas casein is normally useful at night to promote sustained release during the night. By combining both types in a protein blend you will theoretically be okay to take the same protein product at all times with the whey releasing quickly and the casein slowly.

Isolates are one of the quickest absorbing proteins on the market. People will find this source of protein to be a bit on the expensive side, more-so than whey concentrates. These proteins are perfect for those with low carb diets. Many of the protein tubs on the market these days that are strictly whey isolates have very low if any carbs/sugars. Isolates are great pre and post workout as they are absorbed quickly and can supply the muscle the nutrients needed to help recover and grow.

Soy protein is not that popular when compared to other proteins on the market for bodybuilders. It is a good source of protein for those looking for a vegetarian source of protein. This is a useful source of protein and comes with many benefits to its user. It is loaded with glutamine, arginine (help dilate blood vessels to allow nutrition to get into the muscles quicker), and BCAA's (help with recovery). This type of protein can be used both pre and post workout or anytime throughout the day if needed to get in a meal/snack containing protein.

Whey Protein and Whey protein Isolate have the highest BV value, meaning it is absorbed and utilized more efficiently than any other protein. Because of this Whey protein is ideal to take after a workout, when your body is like a sponge and will absorb more nutrients, and during the day in between meals. Whey protein is especially good to take first thing in the morning when your body has been without protein whilst you have been sleeping. As it is digested quickly it is not the best protein supplement to take before bed
