To provide nutrition for optimum muscle growth, you need to have a good amount of protein in your diet.
 But most protein sources have a lot of fats too; hence, you need to be careful with your choice of the foods in your nutrition plan particularly the protein sources.
To build muscle mass, you need to know the best protein for optimum growth of your muscles.
Among the popular sources of protein in the gym are whey, soy, and casein.
These are supplements in powdered form that one can conveniently mix to create healthful protein shakes and smoothies.
Aside from being highly convenient, these are also readily absorbed by the body.
You also get the pure protein without the fats normally found in protein sources like beef, eggs, and pork.
Soy is one of the protein sources mentioned above.
This is a cheap source of protein that is plant-based.
It is low in fat, cholesterol, and lactose.
It can be your main ingredient to your protein shake.
The main concern however with soy protein is that it contains phytoestrogens, an agent that can counteract with the muscle-building effects of testosterone.
Casein, on the other hand, is the main component of milk.
It is however a slow-digesting protein because it forms a gel-like compound in the digestive system.
Casein is not very effective in protein synthesis because it is not readily absorbed.
It is however effective in suppressing the breakdown of protein.
Hence, it is a good complement to whey protein.
If you want to build more muscles in lesser time, you need to use whey protein because it is readily absorbed by the body.
This makes it very important to protein synthesis.
This protein facilitates the growth of muscle tissues as well as speeding up the recovery of the muscles.
Thus, it is the best protein for your post-workout requirements.
