Whey protein has always been the most popular product in the supplement market. It is easier to be absorbed by the body than all other proteins and enters the bloodstream fastest to achieve protein synthesis. However, the biggest advantage of whey protein - fast synthesis and easy absorption has also become the fatal flaw of whey protein. Scientific experiments have confirmed that due to the rapid absorption and digestion of whey protein, up to 58% of the protein nutrients are not absorbed. Muscle fibers are converted into the body's blood and consumed energy by the kidney system before they are formed. I believe that no fitness enthusiast can accept the cruel fact that 58% of the protein used to replenish muscles is lost every day, but the normal metabolic laws of the human body cannot be changed. When sports medicine experts discovered this phenomenon, after a long period of hard research and experiments, they finally invented a new generation of protein products, which is the whey protein isolate currently popular in the US market.
Whey isolate is based on whey protein and then purified by high-temperature ion filtration. Its product has the following advantages over ordinary whey protein:
Higher biological value When whey protein first entered the market 10 years ago, it became very popular, replacing the egg protein, milk protein and meat protein that people have used for a long time. The main reason is that the biological value of whey protein isolate is 128 [BV-128]. The highest biological value makes the nitrogen balance and protein synthesis level of whey protein isolate after entering the human body higher than any other protein. It is a protein product and can provide maximum protein nutrients to repair and synthesize muscle fibers. Its unparalleled protein purity makes it extremely easy to absorb. It is a solution to the long-term distress of some people who are allergic to protein and have diarrhea.
Improved protein utilization Due to the re-purification of protein, whey protein isolate is rich in higher quality amino acids such as glutamine, branched chain amino acids, leucine and other amino acids. These high High-quality amino acid components significantly slow down the loss of protein in renal metabolism, increasing the protein utilization rate of muscle fibers to 92%.
Prolongation of protein release period Protein release period is still a relatively unfamiliar term to domestic bodybuilders, but it is a key that cannot be ignored for every bodybuilder. The protein release period refers to the rate at which ammonia is synthesized by protein in the body after ingesting protein nutrients. The popular explanation is the time period for each ingested protein to take effect in the body. General proteinSources of protein, including ordinary whey protein, will be consumed or decomposed within a short period of time after being ingested by the human body, while the body's metabolism and muscle fiber synthesis are carried out 24 hours a day. Especially during the 8 hours we sleep, the body is also busy metabolizing, and it is impossible for us to frequently replenish protein during sleep, thus wasting precious opportunities to build muscle. Whey protein isolate is rich in various high-quality amino acids that protect protein components, so that its release period in the body can reach 6-9 hours, which means that you only need to supplement whey protein isolate 1-2 times throughout the day. Coupled with normal dietary nutrition, your muscle fibers can receive protein supplements 24 hours a day.
Using science to observe proteins:
Observe the state of various protein nutrients under an electron microscope. Scientific experiments have confirmed that the largest state of the amino acid molecules in the protein is the least prone to decomposition and loss. Observation has confirmed that the amino acid molecules in whey protein isolate are 2,000 times larger than other proteins, making it the most beneficial protein source for muscle synthesis.
At present, as people have fully experienced the advantages of whey protein isolate, whey protein isolate has gradually replaced whey protein products in foreign markets. Major supplement companies are also rushing to produce their own whey protein isolates. But due to its high manufacturing cost, its retail price in the United States is also much higher than other protein products.
