Whey protein is a rare protein essence extracted from milk, and its content in milk is only 0.7%. It is rich in 8 kinds of amino acids (other amino acids can't be synthesized), low in fat and sugar, and easy to be absorbed by human body quickly. Known as "Fast Protein", it is the first choice for fitness people to supplement protein efficiently. Because whey protein is rich in branched-chain amino acids, it can promote the synthesis of muscle protein, which is more suitable for sports and fitness people. Supplementing 20 grams of whey protein every day can obviously reduce the fat content in the body, help maintain the good state of muscle quality and promote the utilization of fat. In addition, timely supplementation of whey protein after exercise can promote the recovery of muscle tissue, increase muscle strength, promote the synthesis of hemoglobin, and effectively relieve muscle soreness after exercise.
It is better to take whey protein about half an hour after exercise. Muscle growth is not during strength training, but after strength training and when we rest. At this time, it is even more necessary to supplement high-quality protein, protein powder and vitamins, which is more conducive to the absorption and transformation of protein, such as bananas, olive juice and broccoli.
If the purpose of fitness is to gain weight and muscle, it is a good choice to supplement protein powder appropriately. The well-known brands of whey protein powder are: muscle strength, Upton, BSN, violent nutrition and so on. Opal's is more suitable for beginners, BSN's and Geshi's are compound proteins, which are more inclined to slow release and more suitable for high play. Amway's protein powder is plant protein, which has no effect on muscle gain.
Friendly reminder: eating too much protein powder has certain side effects, which can't be seen in a short time. If you eat too much, it may lead to a series of pathological changes, such as arteriosclerosis, gallstones, uremia, excessive renal function burden, excessive muscle growth, etc., leading to unbearable heart and blocked blood circulation.
So, if you are not a professional bodybuilder, don't eat it. I suggest that you choose food supplements and eat meat rich in protein, such as beef, chicken breast or egg white.
