My wife's Ob-gyn Doctor has had her take take Vit D for many years (>20) ever since she first went to his care. He was known by other doctors in town as the Vit D doctor for advising his patients to take it, and he checks her levels yearly to make sure she is on target. I caught the swine flu and sick as a dog with parvo for a week. She had it for two days max and did much better than I did.
