Protein is basically made up of amino acids which are the basis of building and repairing muscle tissue.
Protein powder is basically a dairy product in a concentrated form derived from either Whey, Casein or Soy.
Taking protein powder is a great way of increasing your protein intake if you are stuck for time and cannot eat and digest large quantities of beef, seafood, chicken and poultry.
There are many protein powders in the market that differ in type, quality and taste.
Whey protein is a made up of a substance called globular protein that are derived as a by-product in cheese production.
The whey is taken through a bunch of separation processes to be converted into whey protein.
The number of separation processes the whey goes through determines the type and quality of whey protein that is produced.
Casein is a protein that is abundant in milk. Casein protein is made by also separating clusters called micelles from the milk to make casein protein powder.
It is the cheapest form of protein compared to whey protein isolate, hydrolyzed whey protein and casein protein.
It is a lower quality protein, has a lower amount of protein per serving roughly 70-80% per serving and contains a larger amount of fat and cholesterol compared to other whey proteins.
This is a higher quality of protein brought about by removing water, fat and lactose from the whey.
This results in a product that has a higher amount of protein per serving roughly 90% per serving, a better quality protein with a faster rate of absorption in the body.
This is a more expensive protein than whey protein concentrate.
This is where the product contains both types of protein. I am not a big believer in this because you do not know how much per serving is whey protein concentrate and how much is whey protein isolate and it is more expensive than whey protein concentrate.
For all you know, it might be mostly whey protein concentrate with a sprinkling of whey protein isolate.
I recommend that you stay away from blends and go with either the concentrate to save money or the isolate if you can afford to spend more money.
Hydrolyzed whey protein is the highest quality of protein available that is sourced from cow’s milk.
The whey protein s broken down and separated into a higher concentration of short amino acids and peptide bonds.
It has a higher absorption than both whey protein isolate and whey protein isolate. It more expensive than whey Protein Isolate.
I am going to sit on the fence about this one, not sure if the extra money is worth spending on this.
Casein is a protein found in milk. Unlike whey protein, casein protein is absorbed in to the body at a much slower rate.
Casein protein is generally taken before you go to bed to allow the body to be supplied with amino acids stimulating protein synthesis over a longer period of time.
Whey protein is absorbed quickly bit protein synthesis is over after a short period of time.
If you are prepared to spend the money and are serious about building muscle mass and strength then combining casein protein with whey protein isolate is a good thing.
