Whey protein after workouts because it gets into the blood quickly. Casein protein before bedtime because it takes a long time to fully get absorbed into the body. Soy and egg protein should be used during the day as part of a meal.
Whey protein is a super source of protein for athletes, bodybuilders and those looking to lose weight. Whey Protein Facts:
1. Whey protein is the best source of amino acids available. It has a complete amino acid profile, no other protein source contains this. Amino acids are not only vital for many body functions, they are the building blocks of protein and are essential to muscle growth and recovery. Without adequate amino acids in the diet performance and muscle growth will be hampered. 2. Whey protein is absorbed faster than any other protein source. This makes it ideal for drinking after workouts, and first thing in the morning when the body needs nutrients and aminos as quick as possible. 3. Whey protein isolate is practically fat free. It’s also lactose free. Whey protein isolate is filtered and can be almost 95% pure protein! 4. Whey protein isolate (the most purest form of protein) contains the highest biological value of any protein source. Biological value (BV) is a measure of how quickly and efficiently the body can use a protein source. The higher the better. 5. Good whey protein supplements are also high in Glutamine. Glutamine is the most abundant amino acid in the body, and is responsible for muscle repair and regrowth as well as being the primary fuel for the immune system. 6. Whey protein is now the most common ingredient in weight loss drinks, meal replacements and products.
Casein protein plays a major role in building muscle. Whey protein is quick digesting, but that can also be its downfall. There are 2 times of the day where I would definitely choose casein over whey and those are before bed and during the day (not after workout though). Casein has a slower release into the body. Casein takes up to 7 hours to be fully absorbed by the body, that’s 7 hours of vital protein being delivered to muscles that are repairing after intense training sessions. Casein is often referred to as night time protein, and it is.
Soy protein is a complete protein that ranks right up there with the best. I never take pure soy protein powder, but what I do to get the benefits of soy protein is that I mix my whey protein with soy milk.
Egg protein is absorbed by the body at a rate in between the fast absorbing whey protein, and the slow absorbing casein protein. It's a protein that can be consumed at pretty much any meal.
