Sunshine is important in our lives because it converts to vitamin D in our bodies. Because modern work days keep us indoors most of the time, we may not be getting enough of this precious vitamin. Schedules usually start at sunrise and end at sunset preventing us from seeing much of the sun in-between. And even though vitamin D occurs naturally in some foods, it provides such a small amount that it may not be enough to sustain our overall health. Recent studies have made the scientific community take another look at vitamin D. In addition to helping support bone health, new studies suggest that vitamin D may help with immune function as well. Data reviewing the effects of vitamin D on human health from Harvard University is so impressive that the American Cancer Society is currently reviewing its sun protection guidelines. In addition to sunshine and the proper diet, supplementation may help to provide us with the vitamin D our bodies may need. Some supplements out on the market provide vitamin D-2, a form which the body may have trouble absorbing. Vitamin D-3 is far more desirable because it is the substance that is formed as the sunlight touches human skin. Just one Sunshine in a Tablet from Nutritionworks provides you with 2,000 IU of vitamin D-3.
