Andy, 52, was very surprised when his doctor told him that his blood levels of vitamin D were below normal. After all, he plays tennis or rides a bike on most days. However, he forgot that the time for vitamin D synthesis from sun exposure is only from 10:00 AM to 1:00 PM for most locations in the United States, and he does most of his activities after work. Because his sun exposure is not adequate, he has to rely more on diet and supplements for his vitamin D needs. Andy’s doctor asked him to consume 600 IU of vitamin D daily. He is supposed to track his vitamin D intake from foods and take a supplement if he does not meet his daily goal. It sounded easy, but he was up for a surprise. Some foods had the amounts of vitamin D listed in micrograms, others in IU. Most supplements have the amounts of vitamin D listed in IU.
