Vitamin D is crucially important vitamin, playing a key role in the maintenance of normal healthy bones, teeth and muscle function. Our bodies can not produce Vitamin D by themselves, only when we expose our skin to sufficient amounts of strong sunlight or eat enough Vitamin D from food. Both of these things are difficult to achieve, especially in our climate. The third option is supplementing with a high quality Vitamin D tablet. This is the best way to ensure we get optimal amounts of important Vitamin D in our diets every day, regardless of food intake, weather and sunlight. Vegans, older people, and anyone who has little exposure to sunlight can particularly benefit from FSC Vitamin D tablets.
