"You cannot get 600 IU of vitamin D daily from diet unless you eat salmon 3 times a day and drink 2 gallons of milk a day," said Michael Melamed, MD, MHS, Albert Eistein College of Medicine, quoted in JAMA, 2011;305 in an article about the importance of Vitamin D. But don't go crazy--too much can cause problems and put you at risk for cancer, cardiovascular problems, falls and fractures.
