If you can't keep up with the basic diet, get up one spoon early, 1 spoon before going to bed, half a spoon before training, 1.5 spoon after training, and take it in cold water.
Extended data protein powder is generally made of purified proteins such as soybean protein, casein, whey protein (lacking isoleucine) and pea protein, or the combination of the above proteins, and is rich in protein. Its purpose is to supplement protein for people who lack protein, and it can also be used as a functional additive in food industry.

Milk, eggs, meat, soybeans, wheat and corn contain all kinds of essential amino acids in sufficient quantities and appropriate proportions. Moreover, the psychological enjoyment and sensory stimulation brought by food can not be replaced by protein powder. Excessive intake of protein is not only a waste, but also harmful to human health.
