VITAMIN D is a fat-soluble vitamin that is naturally present in very few foods, added to others, and available as a dietary supplement. It is also produced by the body when ultraviolet rays from sunlight strike the skin and trigger vitamin D synthesis.<\/p>\n

However, vitamin D obtained from sun exposure, food, and supplements is biologically inert and must undergo two hydroxylations in the body for activation.<\/p>\n

The first occurs in the liver and converts vitamin D to 25-hydroxy vitamin D, also known as calcidiol. The second occurs primarily in the kidney and forms the physiologically active 1,25-dihydroxyvitamin D also known as calcitriol.<\/p>\n

Vitamin<\/span><\/a> D is essential for promoting calcium absorption in the intestines and maintaining adequate serum calcium and phosphate concentrations to enable normal mineralisation of bone and prevent hypocalcemic tetany.<\/p>\n

It is also needed for bone growth and bone remodelling by osteoblasts and osteoclasts. Without sufficient vitamin D, bones can become thin, brittle, or misshapen. Vitamin D sufficiency prevents rickets in children and osteomalacia in adults.<\/p>\n

Together with calcium, vitamin<\/span><\/a> D also helps protect older adults from osteoporosis.<\/p>\n

We are now going beyond the skeletal system and going into the cardiovascular system. Vitamin D it appears, is good for the heart.<\/p>\n

A new study presented on Nov 16 at the American Heart Association’s Scientific Conference in Orlando, Florida, confirmed a strong association between the presence of reduced vitamin D levels and a greater risk of coronary artery disease, stroke, heart failure and dying among men and women 50 years of age and older.
