Generally speaking, eating once a day can meet your own needs, but if you are a fitness crowd with a large demand for protein, you may eat three or four times a day. So the specific frequency depends on the body's demand for protein.

Protein powder is a combination of purified soybean protein, casein, whey protein or pea protein, which is a supplement of protein. Ordinary people should supplement nutrition and eat normally. For example, a spoonful (14g) of Tomson Bejian protein powder a day can meet the daily demand for protein.
