There are many types of protein powders. Everyone has advantages and disadvantages. The two most common are soy protein and whey protein. Discuss between soy and whey protein and which is better to use before, during, and after weight training. So, let’s take a look at protein whey vs soy:
Protein Whey vs Soy Comparison
Protein Whey vs Soy Comparison
Soy protein has less ability to produce ammonia. Ammonia is a major cause of muscle fatigue. For this reason, soy protein is best used before and during exercise. Soy protein also contains phytochemicals. Phytochemicals are thought to help with heart health and prevent osteoporosis.
When soy protein is digested, it promotes rapid muscle synthesis. It provides a high concentration of BCAAs that the body easily converts to energy. Soy protein helps build muscle. This, however, might not be the best protein choice. Soy protein is in the middle of the pack when it comes to muscle protein synthesis.
Possible Harms of Soy Protein
While soy protein has many benefits, there are some concerns.
Soy protein contains phytates, also called antioxidants. These antinutrients also reduce the amounts of iron and zinc. However, phytates should not harm your health unless you eat a very unbalanced diet and are completely dependent on soy for iron and zinc.
An additional concern is that soybeans can impair thyroid function. Isoflavones in soy can interfere with the production of thyroid hormones and the amount of iodine through the thyroid. However, studies show that soy has little effect on thyroid function.
The Benefits of Whey Protein
Protein supplements have the highest biological value (BV) of all protein sources. BV classifies the availability of protein sources after digestion. Whey protein is the fastest absorbing protein. This makes it ideal for post-workout consumption. For over 50 years, whey protein has been considered the perfect protein supplement. It can surpass all other protein powders in building muscle. Whey protein is absorbed relatively quickly by the body after use. It is easy to digest and absorbs about 100% of whey protein.
Possible Harms of Whey Protein
The sixth important carbohydrate in protein is lactose. Lactase is the enzyme needed to digest lactose. Whey concentrate is the least processed form of whey and causes the most stomach upset. For those who suffer from lactose intolerance, converting to isolated or chlorinated hydrolysis can relieve gastrointestinal symptoms. Isolated and hydro isolates are better treated and more lactose is removed. This makes them more ideal and suitable for people with lactose intolerance.
