Soy Protein Supplement for Building Muscle Mass

Soy protein supplement powder is made from soy beans. It is high on the Protein Digestibility Corrected Amino Acid Score (PDCAAS). It is low fat, sometimes fat free, as well as cholesterol and lactose free. This makes soy a great source for those who are lactose intolerant. It is also a great meat substitute for vegetarians and vegans.

Soy is ideal for low carb, high protein diets. It contains saponins, phytosterols, and isoflavones. Saponins help to support a healthy immune system and also help to reduce the absorption of cholesterol in the small intestine. Phytosterols have also been shown to help maintain cholesterol levels. The isoflavones act as powerful antioxidants to help promote positive health in both men and women.

Compared to other proteins soy falls a bit short in terms of Biological Value, and has less methionine, a protein that helps in protein synthesis. I would recommend that if you are not lactose intolerant, or not a Vegan, that you choose another protein powder. If you are a member of the two groups just mentioned, then this is a great way to add extra protein to your diet.
