I take a daily multivitamin and eat very healthy by most college-student standards.
See the amount of mg each vitamin has on the multi and compare to a minimum daily. Say D3 you may want 5000ug/day, while the multivitamin has 100ug/day.
Do you train ? It fixes your head too. Something that you like or run/swim/box/kickbox/muaythai(no headshots)
i tend to disagree with this, i hear people say that exercise is helpful for cognitive enhancement but i found doing any significant amount of exercise leaves me drained and i find my mental performance slips
Exercise after work. Or do light one before work. But you need it. Or before sleeping so the day is closed.
