Did you know?
Casein is the major component of protein found in milk accounting for nearly 70-80% of its total protein and is responsible for the white color of milk.
Let’s understand little bit more in detail about Casein:
What is Casein?
Casein is a protein that is derived from milk. It is found in the solid part of milk when separated and it is the basis of curd and cheese.
How different is Casein from Whey?
Both carry same amino acid profile, but As compared to whey, it is a slow-digesting protein and it may take up to 7 hours to be absorbed by the body. Because it is a slow-digesting protein, it is popularly taken prior to bedtime to provide amino acids to muscles while sleeping, unlike whey protein. Casein is sometimes used in combination with whey protein to provide a slow and fast-acting blend of protein. Steady protein release allows for muscle fueling potential over time. Casein has naturally high levels of glutamine.
When should one take Casein?
Since it takes time to absorb casein and releases amino acids slowly as compared to whey, It iss great to have in the evenings or before sleep. This way casein helps to maintain anabolic
Advantages of Casein Protein:
- Useful for night-time meal to provide long term.
- Casein will usually offer 50-80% absorption, more if you are resting.
- Slows down the rate of protein breakdown, protecting your existing muscles.
- It usually mixes up in a thicker format, so it is great for certain recipes.
- Long shelf life.
- Inexpensive to produce.
Backed-up with Research Studies
Several studies have done to understand the difference and benefits of whey over casein and vice versa.
One of the studies have shown that whey do improve protein synthesis, but not the protein degradation whereas whey reduces protein degradation and not protein synthesis.
Another study showed that the protein levels in the blood after whey consumption improved within 4 hours, unlike who consumed casein protein. What was interesting in this particular study was that the whey protein peak came down to the baseline within 4 hours, whereas casein protein peak took 7 hours to reach the baseline.
Hence, from these studies it is very clear that both have their own place in the protein category. If you are into intense training, it is important to include whey protein during your workouts and casein around fasting periods.
GNC being committed to your health since 80 years, does not only cater to whey protein category but also have casein protein – Beyond Raw® ISO Casein PM.
For this product, our scientists have chosen a specific type of casein, called native micellar casein. This is a spray-dried micellar casein isolate prepared from top quality fresh Dutch milk using an innovative, low-temperature microfiltration process.
Due to minimal processing, the casein protein is present in its native, micellar form & also ensures a high concentration of the protein content. Micellar casein is slowly broken down in the stomach into smaller amino acids where it can be used by muscles for recovery & preserving muscle glycogen stores. Because of this slow absorption, casein is typically consumed by athletes before sleep.
