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? Formulated using vitamin D3, the form of vitamin D most readily absorbed by the body, each small ‘easy-swallow’ capsule provides 4,000iu of vitamin D3.
