My daughter just turned 15, & acts bipolar. upsets whole family! mood swings, boyfriend problems ...thinks she's inlove! what vitamins could help ?

Vit E: EVALUATION: The "vitamin" i would respectfully suggest the most is a general health and mental health evaluation with her doctor. (vitamin "e" = evaluation). Bipolar disorder can show up in adolescents, but so can substance abuse and many other issues. Being in love is a regular part of adolescence so that doesn't seem unusual -- but possibly what she's doing with this, could be. Psychiatrist can help.

Unfortunately none : There are no studies showing any vitamins will help this kind of behavior. Please get her evaluated by a psychiatrist.
