Should I Take Vitamin D Every Day?
Vitamin D helps regulate the amount of calcium and phosphate in the body, and are needed to keep bones, teeth and muscles healthy. A lack of vitamin D can lead to bone deformities such as rickets in children, and pain in the bone caused by a condition called osteomalacia in adults. In temperate countries, from about late March or early April to the end of September, most people should be able to get all the vitamin D they need from sunlight. The body creates vitamin D from direct sunlight on the skin when outdoors. But between October and early March we don’t get enough vitamin D from sunlight. Vitamin D is also found in a small number of foods, like oily fish (eg., salmon, sardines, herring, mackerel and fresh tuna), red meat, liver, egg yolks, and fortified foods (such as most fat spreads and some breakfast cereals). Another source of vitamin D is dietary supplements. In the UK, cows’ milk is generally not a good source of vitamin D because it isn’t fortified, as it is in some other countries. Taking too many vitamin D supplements over a long period of time can cause too much calcium to build up in the body (hypercalcaemia), which weakens the bones and damage the kidneys and the heart.
