Which type of vitamins are good for a teenage girl to take?

Calcium/iron maybe: There's nothing in supplements that can't be found far more cheaply and safely in real food, regular exercise, enough sleep, and enough water. Spend your money on well-fitted athletic shoes, a good mattress and lean meat, colorful vegetables and fruit. Teen girls often don't get enough calcium and iron. If you think she's deficient here, talk to her doctor.

Vitamin D, Multivit.: Everyone in the us (unless in deep south) needs to take vit d in fall & winter months- adult dose is 5000 iu/day-& take in spring/summer if not getting mid-day sun without sunscreen. Vitamins are no substitute for a healthy diet but the majority of americans are deficient in calcium, magnesium, chromium, vit. A, e & chromium. A good mulitvit with iron provides insurance; a prenatal is appropriate!
