(1) Whey protein

Whey protein powder is a precious protein separated and extracted from milk using advanced technology. It is promoted as the "King of Protein" due to its many advantages such as high purity, high absorption rate, and the most reasonable amino acid composition. Whey protein is not only easy to digest, but also has high biological value, high conversion rate, high protein efficacy ratio and high utilization rate. It is a high-quality protein. It contains all the essential amino acids required by the human body. Its amino acid composition pattern is almost exactly the same as that in skeletal muscle, and it is extremely easy to be absorbed by the human body. Whey protein is also the richest source of natural branched-chain amino acids, which help delay exercise fatigue, reduce muscle damage, promote muscle synthesis and relieve post-exercise pain.

Whey protein is even more important for active people. Exercise not only consumes a lot of energy, but also intensifies protein catabolism, and may even lead to a negative protein balance. Therefore, protein intake should be increased, especially high-quality protein. For example, appropriately increasing the intake of whey protein plays an important role in supplementing protein loss during exercise, increasing muscle strength, promoting hemoglobin synthesis, and eliminating fatigue. Because whey protein is rich in branched-chain amino acids, it can promote muscle protein synthesis and is more suitable for sports and fitness people.

(2) Complex protein

Complex protein is generally made from whey protein, egg protein, casein, soy protein and other proteins in a certain proportion. Its main purpose is to comprehensively supplement protein for fitness enthusiasts and release it in the body at the same time. longer.

(3) Casein

It is a large, hard, dense curd that is extremely difficult to digest and break down. It is precisely because of this characteristic that casein is often selected by bodybuilders as the best protein to take before going to bed to ensure that the body can slowly digest protein and continue to absorb amino acids during the 6-8 hours of sleep.

The main difference between the above three proteins is the absorption rate. Whey protein has the fastest absorption rate and can be absorbed within 30-40 minutes; the complex protein absorption rate is moderate, about 2 About hours; casein absorption rate is the slowest, about 4-6 hours.

In daily use, whey protein is most suitable to be taken immediately after training (it can also be supplemented after 30 minutes), which can provide the body with an excellent protein supply in the shortest time; complex protein is suitable for getting up in the morning or used as a meal replacement pack during the day. , providing sufficient nutrition for work and study during the day; casein is suitable for taking before going to bed to ensure that the body can continue to absorb protein at night and ensure muscle anabolism.
