Soy protein isolate is a protein powder supplement taken to suffice nutritional requirements. It has to be taken only in recommended levels since its overuse can cause a number of health complications and disorders. Read on to know more...
Soy beans and other soy products are considered to be an ideal source of proteins for vegetarians. Soy protein isolate, which is a soy product and a nutritional supplement, is a rich source of amino acids.
Soy protein is extracted from soy beans whose fat has been removed. This protein substitute is in the form of a powder, and is available in two forms in the market: concentrate and isolate. The concentrate tastes similar to a bean powder and contains traces of carbohydrates.
On the other hand, the isolate is the refined and purest form of soy protein, and it does not have a flavor. This is because all the carbohydrates are separated during the extraction process so that only dried protein is remaining. Hence, soy protein isolate is an excellent protein powder supplement.


Soy protein isolate is used in foodstuffs to enhance their nutritional value. Here are some of the benefits of this nutritional supplement:
  • As soy is rich in essential omega-3 fatty acids, vitamin B complex, iron, magnesium, and other minerals, which are beneficial for the overall health of the body.
  • Consuming this supplement after an exercise session can help in body building and improve the muscle gain. Hence, it is a favorite among athletes, bodybuilders, and fitness competitors.
  • It has been found out that the isolate has the ability to lower the cholesterol levels in the body. This protein substitute can reduce the levels of bad cholesterol (or LDL cholesterol) in the body, and hence reduce the risk of getting heart diseases.
  • Since the isolate is also a rich source of calcium, magnesium, and boron, it helps strengthen the bones. Research has proved that soy flavonoids help keep osteoporosis and other bone-related disorders at bay.
  • Including soybean in the diet can prevent and even treat prostate cancer.
  • For women, the isolate relieves the symptoms of menopause like mood swings, night sweats and hot flashes, etc. Since soy isoflavones have estrogen-like properties, they also help maintain the optimal body temperature.


Though there have been many proven benefits of soy protein in your diet, there are also a few risks, which should not be ignored.
  • Certain individuals may experience hormone imbalance as a result of phytoestrogens. This plant-derived compound may function similarly like the estrogen, and have a negative effect on the growth and development of the body. 
  • The body's ability to digest and absorb nutrients is delayed due to the presence of anti-nutrients. This can cause a problem in the digestive system like indigestion, and may also effect the overall health of the individual.
  • Over consumption of this supplement can lead to low libido, reduced sperm count, and erectile dysfunction in men.
  • Before processing the soy protein isolate, the soybeans are washed in acid in aluminum tanks. Artificial flavorings and nitrites are added to add flavor to the protein powder. The presence of so many chemicals can lead to allergies, different types of cancer, and autoimmune disorders.
Thus, it is essential to consult a health care provider before including any supplement in your diet in order to avoid any health complications.
