Vitamin D is a nutrient your body needs for building and maintaining healthy bones. That's because your body can only absorb calcium, the primary component of bone, when vitamin D is present. Vitamin D also regulates many other cellular functions in your body. Its anti-inflammatory, antioxidant and neuroprotective properties support immune health, muscle function and brain cell activity. Vitamin D isn't naturally found in many foods, but you can get it from fortified milk, fortified cereal, and fatty fish such as salmon, mackerel and sardines. Your body also makes vitamin D when direct sunlight converts a chemical in your skin into an active form of the vitamin (calciferol). The amount of vitamin D your skin makes depends on many factors, including the time of day, season, latitude and your skin pigmentation. Depending on where you live and your lifestyle, vitamin D production might decrease or be completely absent during the winter months. Sunscreen, while important to prevent skin cancer, also can decrease vitamin D production. Many older adults don't get regular exposure to sunlight and have trouble absorbing vitamin D. If your doctor suspects you're not getting enough vitamin D, a simple blood test can check the levels of this vitamin in your blood. Taking a multivitamin with vitamin D may help improve bone health. The recommended daily amount of vitamin D is 400 international units (IU) for children up to age 12 months, 600 IU for people ages 1 to 70 years, and 800 IU...

If you've ever been shopping down a long aisle full of vitamin supplements, you may have noticed that while some of them are labeled in the metric system ( grams, milligrams or even micrograms), others are labeled in something called "IU." The IU stands for international units, an internationally accepted method of quantifying the biological effect you can expect from a dose of fat-soluble vitamins. According to IU definition is "a quantity of a biologically active substance (such as a vitamin) that produces a particular biological effect agreed upon as an international standard." Or, to put it another way, international units are a way of quantifying the biological effect you can expect from a vitamin dose. Each of these vitamin forms has a different level of biological activity or, to put it another way, you need different quantities of each form to achieve the same biological effect. Because of that, you can't standardize recommended doses by the weight ( mcg, mg or g) of each vitamin, because the same quantity in one form would achieve a somewhat different biological effect than the same weight in another form. So instead of standardizing weights that would achieve different effects, authorities decided to quantify the effect into something called an IU, or international unit. You can convert IU into weight measurements like mcg, mg or g, although the conversion factor is different for each form of the vitamin. Said conversion factors were laid out in the early 1900s p...
