• Vitamin D necessary for calcium absorption Cloudy days, sunscreen and certain diseases can all affect the absorption of the vitamin.
• More importantly, it is synthesized in the skin after exposure to sunlight.
• Calcium cannot be absorbed without vitamin D. It works with other minerals and hormones to promote mineralization of bones (building bones).
• If there is a deficiency of vitamin D, a person may develop osteoporosis (thin, brittle bones) or a softening of the bones.
• In children this is called rickets and in adults it is called osteomalacia.
• Primarily this is due to an inadequate amount of sun exposure to synthesize vitamin D; it is more common the further you are from the equator.
• However, complete cloud cover also will decrease the amount of vitamin D by about half and sunscreen with an SPF of 8 and more will decrease it by 95 percent.
• A. We can boost vitamin D levels in the winter by taking a supplement once a day or increasing ingestion of foods that contain vitamin D. Also, some researchers suggest that a short exposure to sun --- 15-20 minutes without sunscreen --- will improve vitamin D levels.
• Q. What foods are high in vitamin D?
• A. Fatty fish and fish oils are the best sources of vitamin D. Cod liver oil has the most, followed by salmon, eel, herring and tuna and sardines in oil.
• A. Recently, the recommended dosages have been increased to the following: 200 international units per day for infants, children, pregnant or lactating women and young adults; 400-600 IU/day for those 50-70 years old and 600-800 IU/day for those over 70.
• The recommended tolerable upper limits are as follows: 1000 IU/day in infants and 2000 IU/day in all others.
