Vitamin D is obtained from sun exposure, and is commonly known as the sunshine vitamin. Unfortunately due to lifestyle changes many do not reach the recommend levels of sun exposes, reducing the amount of Vitamin D in the body. Food and vitamin supplement are now commonly used to help the body to absorb and utilise the calcium it needs.About 99% of the calcium in the body is in the bones and teeth and 1% is in the blood, muscles, and other soft tissues (such as nerves, organs, etc.) Vitamin D is also important for hormone regulation, inflammation reduction, and the optimal functioning of the nervous system and the immune system.Why Take Vitamin D?If your body cannot produce enough vitamin D because of insufficient sunlight exposure you will need to obtain it from foods and perhaps supplements. Experts say that people with a high risk of vitamin D deficiency should consume 400 IU of vitamin D each day so that there is a good level of 25-hydroxy in the bloodstream.Take Vitamin D if you want to Aid absorption of calcium Aid bone and teeth structure Help regulate your immune system, cell growth and nerve transmission Help treat weak bones
