Why Soy Protein is Among the Best Protein Supplements

Soy BeansThere are tons of different protein supplements on the market. So many, in fact, that it may be difficult to decide what the best protein supplement for you is. While there are almost too many protein supplements to choose from, one that has received bad press happens to be one of the best: soy protein isolate.

Although not as vigorously touted by bodybuilding supplement manufacturers as whey protein concentrate and whey protein isolate, soy protein isolate is an ideal source of protein and has many advantages: It is inexpensive; it is a very high-quality protein; and it has a pleasant, mild flavor. Whatever you are looking for in a protein powder, there’s a good chance you will be able to find it in soy protein isolate.

To better understand exactly why using soy protein isolate is a good way to meet your daily protein requirements, you need to understand how soy protein isolate is produced. Soy protein isolate starts out as soybean flour added to purified water. After a complex mechanical and chemical refining process, the end result is a highly purified, very absorbable protein.1

Of course, advocates of whey protein argue that it is better absorbed than soy protein isolate, making it a superior source of protein. While it is true that whey protein powder is a better source of protein than soy protein isolate, the difference between the two is not that large. And soy protein isolate has the advantage of being much better tasting while containing no sugars (useful for athletes trying to avoid fat gain).2

The Flavor of Soy Protein Isolate vs. Whey Protein Powder

  • Soy protein isolate has a very bland flavor – making it perfect for blending up in fruit shakes and other flavorful beverages. Soy protein isolate’s lack of a distinct flavor means that you don’t have to worry about it overwhelming the flavor of the other ingredients in your protein shake. It also means that it doesn’t leave a nasty aftertaste in the mouth.
  • Whey protein powder has a very distinctive flavor: Some like it and others loathe it. If you enjoy the taste of whey protein powder, then go right ahead and eat as much of it as you want. But if you are like many people who can’t stand the taste (and especially the noticeable aftertaste) of whey protein powder, it is probably a good idea for you to try out soy protein isolate.

How to Go About Figuring out the Best Protein Supplement for You

It’s a truism that everybody is different and you can see some of the consequences of this in how different individuals react to different protein powders. Some individuals are more able to digest soy protein isolate without any digestive hiccups, while others are more able to digest whey protein powder without any problems.

You need to experiment to find out what protein powder works best with your digestive system. A few rare individuals can’t tolerate any kind of protein powder at all, and if you are one of them, you might have to meet your protein needs by consuming large amounts of eggs or egg whites.

Protein is essential for bodybuilders and has a wide range of positive effects that go far beyond helping people gain muscle.3 To get enough protein to perform at your best, you almost have to supplement your diet with a protein dietary supplement.
