Whey and soy proteins are currently the most popular ones. They have a range of advantages that differ them from others and from each other, too. Still, each of them lacks something that can be found in another one, and the comparison of whey protein vs soy protein we will see below.

Digestion

Whey protein is digested by the body in a very quick and easy way. This feature makes it a perfect choice for those people who need to recover after a heavy workout fast. With the help of its amino acids, you will quickly restore the muscle weight you have lost during a workout, but keep in mind that this protein can be easily withdrawn from the body. You will need to take more of it and more often during your training. Whey protein can help to restore the inner bowel microflora, improve the way your body absorbs calcium and reduces the risk of catching a virus infection.

First of all, it is an ideal choice for strict vegans and those people whose bodies cannot digest dairy products. Soy contains vitamins and minerals that can help your body to function in the proper way. It reduces the risk of breast cancer for women and prostate tumors for men.

Biological Value

If we compare the biological value (digestibility ratio) of whey protein with the soy one, we’ll see that whey protein is ahead with a coefficient of 104, while soy one has 74 points. The same is with the way they are absorbed and used by your body. Whey protein is absorbed and utilized in the body at the rate of 92% (almost fully), while the rate of soy one is about 61%.

Inner Contents

80% of whey protein is composed of alpha and beta lacto globulin. 20% of it is made of biologically active peptides that are easily digested. Free radicals produced by those peptides can ruin harmful bacteria, stop them from getting into the sides of bowels and help the antibacterial activity in general. Glutamine it also contains is a necessary component of the body where it works as a fuel. Several experiments have proved that 30g of whey protein daily can relieve the condition of people who suffer from cancer.

Amino Acids

Compared from the point of view of the quantity of amino acids in them, whey and soy proteins show the same picture. Let’s take 1 as a starting point that shows an average amount of amino acids your body needs. In this case, whey protein will be rated as 1.14, while soy one will show as much as 0.99. Whey protein wins in a comparison from the point of view of the way and quality its amino acids get digested and in a competition related to a quantity of vital amino acids. On these points, whey protein wins without any debate. Still, soy protein shows better results in the quantity of glutamine and arginine.

Negative Effects

There is one negative feature of soy protein: regular amounts of this protein can lead to malfunctions in the endocrine system. Several elements found in soy protein can activate estrogen receptors. That is why, soy protein can often cause harm to thyroid, but only in men. That is why men should reduce their amounts of soy protein leaving it for women who are said to only benefit with its help.
