Protein is an integral ingredient for muscle building. But it is not easy to plan, cook and eat enough protein-rich foods in order to meet everyday nutritional needs. Bodybuilders benefit from protein supplements such as whey or soy protein powder because they are enriched with the essential nutrients needed for producing muscles. Drinking a tasty protein shake is the easiest way, particularly after hard training, to fill your body with nutrients it needs and help muscles recover.
Taking into account the range of protein powders available in this market, it could seem like a confusing task to choose a suitable one. Although whey and soy protein are the two most common sources of protein, the variations between them must be understood to determine which is the best according to your needs.
The amino acid composition in Whey Protein is rich. It supports not only muscle recovery and growth but also promotes fat loss. One of the greatest advantages of whey protein is the fast absorption rate. The body digests and consumes almost all of the whey protein consumed. Though whey protein is considered as the best bodybuilding supplement, it is not an option for some people due to their dietary preferences or food sensitivities.
Soy Protein powders with 90% of protein and usually have 10% of the remaining essential fatty acids, fibers and vitamins. Soy Protein is the only plant-based protein capable of growing lean muscle tissue like whey protein. While soy has a high carbohydrate and fat content, it is no cause for concern because most of these carbohydrates are fibrous, whereas soy fat is unsaturated and rich in omega-3 essential fatty acids.
Importance of Soy & Whey Protein
Both Soy and whey protein have significantly high absorption rates and both will offer a great increase in lean muscle tissue or lean body mass when consumed regularly post-workout. When compared to one another, Soy protein offers the same results as whey protein offers but provides the consumers with a plant-based or vegan alternative to the standard whey isolate proteins.
Soy protein is also seen to show the highest amount of absorption in amino acids and it is the only protein supplement that is a complete amino acid, while Whey protein is also rich in most amino acids. Soy protein also offers health benefits as it keeps the HDL stable (high-density lipoprotein).
Soy also provides aid to bone strength in most cases as well. And the greatest single advantage Soy protein offers over almost all whey protein products is the cost difference. Soy protein products tend to be much cheaper in comparison to whey protein supplements. If you cannot consume dairy or are on a vegan or plant-based diet, soy protein is without a doubt the best choice for you. However, if you are not a vegan and are not lactose intolerant, the choice is up to you, although many people will still prefer and recommend Whey. However, at this point, it simply comes down to your preference.
