I'm a gym coach, and I've studied this before. As long as I want to keep fit and lose weight and gain muscle properly, I don't have to eat protein powder. However, if I want to exercise my muscles, build a tall and strong muscular man or a fitness crowd with insufficient intake of protein in my daily diet, I need to supplement protein powder.
As for the milk protein powder you mentioned, I have also drunk it. This is a product called Xiao Sheng protein. It is a milk protein powder with good effect, and the most important thing is that it tastes great. For many friends with high taste requirements, you can learn about it.
Generally speaking, you need to drink protein powder to supplement the protein in the fitness crowd. The prime time to eat protein powder is 30-40 minutes after fitness, because high-intensity exercise consumes muscle protein, which is not good for muscles, so it must be supplemented in time after exercise. Moreover, drinking protein powder at this time has the best absorption effect, which can not only ensure that muscles will not be damaged due to protein deficiency, but also help muscle fibers to recover and regenerate, and has the best effect on muscle growth. In addition, you can drink some protein powder properly before going to bed, because sleeping is the best time for muscle growth. Eating protein powder before going to bed can not only supplement the consumption of daytime fitness training, help muscle growth, but also ensure high-quality sleep.
