How much D3 to raise level from 22 to normal for teenager?

My daughter is constantly getting every cold and virus going around. She is like the canary in the coal mine and the first one to get anything before anyone else. She is allergic to most airborne allergens and takes shot for them.

She is recovering from a sinus infection and her ENT put her on a course of amoxicillin. Her regular doc finally decided to test her vitamin D levels after going to a seminar and finding herself low. My daughter's levels are 22. The doc said 2000iu of D3 a day would be fine. My daughter is a senior in high school and has missed more school this year than she has attended.

She is also overweight and has polycystic ovary syndrome. I wonder if the D deficiency is related to all of this and if so - what is the best amount and fastest way to get the D in her system? She is a redhead but I wonder if tanning beds might be worth a try.

Any ideas would be greatly appreciated. Thanks!
