Why choose us This Vitamin D supplement is delivered as Vitamin D3, which is the most absorbable and effective form of this nutrient. Vitamin D is naturally manufactured when sunlight hits our skin. This explains why it is known as the sunshine vitamin. This essential nutrient has several important jobs which include regulating levels of calcium in the body, supporting the immune system and muscle function as well as contributing towards healthy bones and teeth. Between October and March the levels of sunlight in the UK aren't sufficient for us to make enough vitamin D. Public Health England recommends that during these months people should take a supplement to top up their levels.
