My brother is in senior three, but he always dozes off in class. Dr. Health recommended their squalene to me. Can it be improved?

Of course it is possible, because squalene is originally aimed at brain hypoxia. Did you find it? We are all sleepy after dinner. Because we are full, oxygen goes to the stomach to digest food, which leads to temporary hypoxia in the brain. That's why we want to sleep very much. We can supplement the squalene you said about Dr. Health.
