Dr. John Chiu answered

Not at your age: If you are deficient in calcium and vitamin D during your growing years, you may have some impairment in bone development. Even then the effect is not dramatic and they certainly won't make much difference at age 20. As for biotin, there is some suggestion that it may improve nail and hair growth although there has been no scientific proof on this.
