If your son is getting a lot of sore throats and colds, chances are he is deficient in vitamin D3. Next time you take him to the doctor, ask the dr to test for deficiency. (simple blood test) I don't know how old he is but an adult can start on 2000 units/day and work up to 5000. Since I have been on 5000, I haven't gotten so much as a sniffle. (4 yrs ago)
