Vitamin D for the DisabledWritten by Mart Gil Abareta
Perhaps, most important source vitamin D is sun exposure. The sun’s ultraviolet rays cause vitamin D synthesis in skin. Ten to fifteen minutes of sun exposure at least two times per week to face, arms, hands or back without sunscreen is usually enough to provide adequate vitamin D. Also, it is very important for individuals with limited sun exposure to include good sources of vitamin D in their diet.According to article “Vitamin D Gains Favor as Health Key” by Tim which was posted on February 29, 2004 at www.ruggedelegantliving.com, emerging research indicates that vitamin D is more important to our health than previously thought, leading an increasing number of scientists to challenge whether fear of sun exposure has made us cover up too much. Doctors are finding an increase in vitamin D deficiencies, even as researchers discover remarkable results from vitamin that affects nearly every tissue in body. Did you know that best known activity of vitamin D is its role in maintaining bones? It functions by increasing uptake of calcium from intestine through interaction with parathyroid glands in controlling bone resorption and serum calcium levels. The skeleton is body's reservoir of calcium and provides calcium through resorption of mineral when serum levels of this essential element drop. It also increases reabsorption of phosphate by kidney tubule, and may directly affect osteoblast, cell which forms bone.
