Milk powder can be drunk by people of all ages for a long time, and so can college students. I'm a junior now. I often drink a cup of Mengniu gold-loaded multi-dimensional high-calcium and high-zinc milk powder for students before going to bed. It feels good for sleep and can supplement nutrition. I started drinking it in my second year of high school. I used to drink Mengniu normal temperature milk. After living in the second year of high school, it is more convenient to use hot water, so I changed to drink this milk powder, because I feel that the milk powder brewed with warm water tastes more fragrant. But Baidu knows more.
