I wanted to take a moment to give you guys a little information on slow digesting protein. We have received a few emails about this so we thought we would try to break it down easily for you all.
While there are a ton of products and food out there that contain protein, slow digesting proteins are essential part of your diet when you are not eating for a prolonged period of time. What they do is create a gel like substance in your stomach. This results in a fixed release of the amino acids into your body. While doing this it will slow the protein breakdown which will increase muscle growth through protein synthesis.
Casein protein contains 80% milk protein while whey protein only contains 20%. Since casein protein is a timed release protein the protein acts slowly on your digestive system which helps it be absorbed at a slower rate than other proteins. This makes it ideal for ingestion before bed or when cutting. Casein is made by extracting it from milk with a filtration process. Some of the best sources of casein protein are milk, cheese, cottage cheese and of course casein protein powder.
Casein protein is a great protein but remember due to its slow digestion it is not ideal to consume post workout.
