Which Protein Should You Take? Soy Or Whey

Protein is a critical nutrient for health used by the body to produce new enzymes and muscle tissue. Protein is present in every cell in the human body to ensure a proper function—all you need to have enough of it in your diet. Protein consists of amino acids, the building blocks that together form protein chains. Your body rearranges these amino acids after digesting dietary protein to create new protein structures needed to conduct different physiological processes.

Drinking protein shakes can be a convenient method to make sure you get enough protein from your diet. Hundreds of soy protein powder are available in the market. If you are confused about buying soy protein, do have a quick search at the USSEC website.


What are Whey Proteins?

Whey protein is a well-known supplement among gym-goers, athletes, and bodybuilders. Studies show it has an excellent amino acid profile that is important for the repair, regeneration, and development of muscle cells. Whey protein should not have a companion to enhance the regeneration process. Of every source of protein, whey protein has the most significant biological benefit (BV). When consumed, the BV score enhances the protein’s absorption into the body. Whey protein is arguably the most readily absorbed protein, just what you want post-workout.

Whey protein comes from the milk of cows. Naturally, cow’s milk contains around 3.5 percent protein and 4% fat. Special enzymes are applied to the milk to extract casein — the milk solids used to produce cheese — from the whey after being pasteurized to remove any bacteria. Further refining removes extract sugars, fats and excess water. The final result is a powder rich in protein.

What are Soy Proteins?

Soybeans are a type of legume which is relatively low in fat and naturally high in protein. Manufacturers ground soybeans into a meal that requires no fat to produce soy protein. Studies say soy protein consists of 90 to 95 percent protein, is then refined into soy protein isolate. The soy protein isolate is then marketed in powder form. Soy protein powder may work great to make a protein drink or add protein to other foods,

Soy protein has a unique composition of amino acids. As the ideal protein to use for endurance training, this structure contributes to its appeal. Although not as high in concentration as whey protein, soy protein also contains many branched-chain amino acids (BCAAs) that are readily converted by the body to generate electricity. Soy has high concentrations of both alanine and histidine, known for its antioxidant and acid buffering advantages. It has a high level of aspartic acid. This acid through the Krebs cycle plays a significant role in the production of energy.

Points to Remember while Choosing Whey / Soy Proteins:

Taste and Touch

Whey protein appears to have a smooth texture and a slightly nutty flavor, somewhat creamy. The nutty taste of soy protein is better, though some people find the texture a little grainier.



Both soy and whey protein are relatively shelf-stable. You may not need to think about whey protein powder going bad quickly, despite being made from milk products. A standard protein powder bottle has a date of expiration that is a year or more out.


Vegan / Non – Vegan

Whey protein is derived from animal products and is not ideal for a vegan diet. On the other hand, Soy protein is vegan-friendly and can be a healthy way for vegans to get ample protein requirements.

Whey Vs. Soy Protein

Because it has less capacity for ammonia production than whey protein, a primary cause of muscle weakness, soy protein is better used before and after exercise. That alone will make soy the preferential option during training, but soy has even more advantages. Soy protein contains a multitude of phytochemicals that enhance protection. Many associations between soy intake and lower rates of certain cancers, especially breast, prostate, stomach, lung, and colon, have been identified by scientific studies. Ideal for women and men over 40 years of age, soy protein includes many phytochemicals known to help improve cardiovascular well-being and optimum levels of cholesterol. For anybody looking for a vegan source of protein soy protein can be an optimum choice. That said, some people prefer whey for its suitability to the digestive system.



There is no “one size fits all” plan when it comes to cooking. Determining the exact variety of soy or whey protein that works best for you can require some trial and error. After using such protein types, certain persons suffer gas, bloating, or stomach issues. Whey protein and soy protein supplements are nutritional supplements that can help fulfil the requirements for every day. Although each protein type has its health advantages, tests have found that soy protein is much superior.
