I remember in college all the smarty pants Nutrition students started taking Multi B's aprrox 3 weeks before exams started.
PMSL...that was me! I studied Nutrition at uni.....and for a good many years chuggalugged back the B's......and still feel safe when I have a stash of Berocca in the house!

Sadly it doesn't work on my hair....nor does In-Liven.
