I am 17 years old and will be 18 in 2 months.i just got diagnosed for vitamin d deficiency and i am taking supplements. can i still grow taller a few more inches?

Hard to say: The potential for any further growth will depend on whether growth centers in your bones are open. Most close by 17-18 in males. An x-ray of your wrist/hand can be evaluated for bony maturity. If the growth centers are closed you are finished.

Agree with Dr. F: You should take vitamin D3 supplementation for bone health. It is not feasible to state if you will grow taller, as that is a matter of your genetics. Have a healthy diet, exercise 30 minutes/day, drink plenty of water, have safe sex, no tobacco alcohol weed or street drugs. For nutrition: http://www.choosemyplate.gov/. Get HPV vaccine. Wish you good health!
