My 22 year old friend ate a whole bottle (150) of mens gummy vitamins will he be okay?

Define "Okay": As a suicide or attention seeking gesture this is not the action of someone who is okay. Most of the vitamins in the product will flush out of the body in a day or two without problems but the Vit A, E, D content may have some toxic effects. Call poison control for details. He should be evaluated in an emergency facility and then receive a psychiatric evaluation.
