What is Vitamin D3? Vitamin D can be obtained through food sources such as eggs, fortified cereals and oily fish, but is predominantly synthesised in the skin through exposure to sunlight. Vitamin D deficiency is common across populations throughout the UK and as a result of a low level of exposure to sunlight, vitamin D synthesis becomes almost impossible in the winter, especially amongst athletes that mainly train indoors. Vitamin D3 supplementation can play an important role in correcting vitamin D deficiency to ensure the maintenance of adequate to optimal levels. Why is ours better? Each vitamin D3 tablet contains our experts’ recommended level of 25µg (1,000iu) of vitamin D3 in its natural form. Vitamin D3 is the form that is made in the human body and therefore the form that our experts insist on using. The result of the extraction and purification process used results in a highly concentrated form of vitamin D3 which offers 99% purity and unparalleled quality.
