Vitamin D is the sunshine vitamin. It is produced in our skin when we are in sunlight and, in fact, we actually get very little of this vitamin from the food we eat. As a result, you might think that it is one of the last vitamins we should be worrying about when it comes to deficiencies of nutritional substances; however, a recent report shows that worldwide more and more people are suffering from low levels of this vitamin. The consequences of deficiencies are significant. This particular vitamin works together with calcium and is important, not only for keeping our organs in peak condition, but also for the normal development and strength of bones. Low levels of the vitamin in adults can increase the risk of osteoporosis and hip fractures. In children, it can lead to rickets which is where the bones become soft and can fracture or even become deformed.
