The major natural source of Vitamin D is dependent on UVB radiation that a person gets from exposure to the Sun. A clear problem with this form of intake is the risk of skin cancer that too much exposure to UVB radiation can bring.
This is where Vitamin D supplements come in. The Vitamin D supplement will give all the benefits the sun will give you, including stronger teeth and bones as well as protection from multiple diseases and conditions such as cancer, type 1 diabetes and multiple sclerosis.
During the autumn and winter months, you need to get vitamin D from your diet because the sun isn't strong enough for the body to make vitamin D. Vitamin D can be found in certain foods, such as egg yolks, red meat, liver and oily fish such as salmon, sardines, herring, mackerel and fresh tuna, however, due to our vastly different dietary needs, these options aren’t available to everyone so again, during these months it may be beneficial for you to take Vitamin D supplements.
Taking too much Vitamin D can result in calcium building up in the body which could lead to weaker bones and damage to the heart and the kidneys, though the amount for this to occur is extremely high. The Vitamin D supplements come in specific sizes, suitable for one a day intake which offers you and your body exactly what it needs. Vitamin D stores itself in your body's fatty tissues which means that any excessive vitamin D that you have accumulated will live in the fat and the liver, thus providing you with a vitamin D source to draw on if your body starts to run low.
