Whey protein vs Soy Protein

 Whey Protein

Whey protein products have always been seen in the last 50 years or so as the perfect protein supplement one should take. When it comes down to other types of protein, Whey surpasses all of them when it comes to building muscle due to its rich amount of amino acids that also aid in the strengthening of bones and the immune system. When we consume whey protein, not only is it digested and absorbed more easily than other protein sources, but we also digest and absorb almost 100% of the whey protein we consume. This is why Whey protein has become the ultimate muscle building post workout protein shake. 

Soy Protein

Soybeans are a type of legume that are naturally high in protein while remaining relatively low in fat. To create soy protein, manufacturers grind soybeans into a meal which contains no hulls or fat. This soy protein isolate is then sold in powder form. The soy protein powder can be used to make a protein shake or to add protein to other meals. Although soy protein isolate is naturally high in protein but very low in carbohydrates, many manufacturers add additional nutrients to commercial soy protein to improve its taste, texture, and nutritional value. 

Which is superior?

they both offer substantial results. Both have significantly high absorption rates and both will offer a great increase in lean muscle mass.Soy protein is also seen to show the highest amount of absorption in amino acids after consumption and is the only protein supplement that is a complete amino acid, while Whey protein is rich in most amino acids, Soy contains all of the essential amino acids. If you compare the biological value of whey and soy protein, whey is a clear winner. Whey scores at 104-110 while the BV of soy usually ranges in the mid-70s. 

supplementation with soy protein resulted in lowered serum testosterone levels. But, there are other studies that dispute this. Whey was seen as a better option as it not only did not affect testosterone levels negatively, it also reduced the response of cortisol during the recovery phase after an intense session of resistance exercise. Cortisol is a catabolic hormone which increases muscle breakdown.

With their high absorption rates, both these supplements offer substantial results when consumed regularly after workouts. Though many people prefer whey protein, they still opt for soy protein products as they tend to be much cheaper in comparison. if you are not lactose intolerant or a vegan, you can opt for whey protein or soy protein powders. The choice is up to you.  

There is no miracle food or such thing that can increase your muscle growth overnight or without doing proper exercise so first be focused on your workouts and meals high in protein.
