Whey Protein VS Soy Protein

Whey Protein VS Soy Protein

As far as sports and health supplements are concerned, we simply cannot argue that the sports supplement industry is worth some seriously big money these days. Pick up any health and fitness magazine and there is literally a sports supplement ad on every other page of the magazine, meaning that 50% of the magazine is basically one big sports supplement product advertisement. As far as effectiveness and popularity are concerned, protein powders rule the roost, and have done for some time now. In fact, protein powders are now so popular and beneficial, that there are dozens upon dozens of different varieties. The most common and popular form of protein supplement is whey protein, in fact it is the most popular sports supplement in the entire world. Soy protein however, is gradually becoming more and more popular and is actually beginning to look set to give whey protein a real run for its money. Protein is a macronutrient that is vital for cellular and muscular growth and repair. Simply put, without protein, we wouldn’t build muscle, our muscles wouldn’t repair themselves, and our cells wouldn’t function or regenerate properly either. Here we’ll be looking at and comparing the two in a great deal of detail, weighing up the various pros and cons of both supplement.

Whey protein

We’ll begin by taking a look at whey protein, the most popular sports supplement in the world. Whey protein is basically a by-product from milk, as it is left behind when milk is turned into cheese. As it provides all essential amino acids that the body requires, it is considered a complete protein source. Whey protein comes in a number of different forms though the most common form is powdered. The whey is dried, filtered, and powdered where it is then combined with vitamins, minerals, flavourings, and other nutrients depending on the actual product itself. Whey protein is a fast absorbing and fast digesting protein, making it ideal for post-workout nutrition as that is when the muscles are most anabolically primed for optimal nutrient absorption.
