Vitamin D is the only vitamin which does not have to be taken as food. Sunlight as well as Vitamin D in our diet is converted into an active hormone by our kidneys and liver – another unique property of Vitamin D. With this dual sourcing, you would think that Vitamin D supplements are totally unnecessary, but this is not the case.
Vitamin D is necessary for strong bone growth and muscle strength and to avoid rickets, osteoporosis and other health problems which are caused by a deficiency of this essential vitamin. Together with calcium, Vitamin D helps prevent older adults from developing thin, brittle bones as they age. It also modulates our immune system and helps reduce inflammation.
Recommended daily intakes by the Food and Nutrition Board are set at 200IU for 14-50 year olds, 400IU for adults 51-70 and 600IU for 71 years and older. However these are now considered too low and the American Academy of Pediatrics, among others, is recommending higher intakes of Vitamin D. To ensure you are getting enough Vitamin D, concentrate on a balance of all three sources:
The best natural sources of Vitamin D are salmon, mackerel, tuna, mushrooms, dairy products including non-fat milk, yoghurt and cheese, orange juice, breakfast cereals and liver.
Those who live in northern latitudes above 42 degrees latitude (Northern California across to Boston) get insufficient UV light for cutaneous Vitamin D synthesis to take place and need Vitamin D supplements. Other areas are affected by smog, seasons, time of day, cloud cover, skin melanin content, sunscreen and a lifestyle which involves living, driving and working behind glass. Researchers found that bodies need 5-30 minutes sun exposure between 10am and 3pm twice a week on the face, arms, legs and back to generate sufficient Vitamin D naturally. However, it is prudent to limit exposure of the skin to sunlight without sunscreen as UV radiation is responsible for 1.5 million skin cancers each year in the US.
Vitamin D Supplements
Those with limited sun exposure and a diet that is not rich in oily fish should take Vitamin D supplements which are inexpensive and readily available. Those who are over the age of 50 should definitely consider a daily Vitamin D supplement to ensure that they are receiving the required daily amount of this essential vitamin.
