Why vitamin D matters in the UK

Between October and early March, sunlight in the UK is not strong enough for skin to make vitamin D, and the NHS advises that everyone considers a daily supplement over those months. People who are indoors most of the day, cover their skin, or have darker skin are advised to consider taking it year round.

What does vitamin D do?

Vitamin D contributes to the normal absorption and utilisation of calcium and phosphorus, to normal blood calcium levels, to the maintenance of normal bones, teeth and muscle function, to the normal function of the immune system, and it has a role in the process of cell division. In children it contributes to the normal growth and development of bone.

Which strength?

The Nutrient Reference Value is 5 micrograms (200iu) and the NHS suggests 10 micrograms (400iu) daily for most adults over the autumn and winter. Strengths above that are widely sold and widely used; 1000iu and 2000iu are our most popular. Vitamin D is fat-soluble and stored by the body, so more is not automatically better - do not exceed the dose on the pack, and speak to your GP before taking high strengths long term.

D3 or D2, and why K2?

D3 (cholecalciferol) is the form the body makes in sunlight and the one in most products here. D2 (ergocalciferol) is plant-derived; vegan D3 from lichen is also available and we stock several. Vitamin K contributes to the maintenance of normal bones, which is why D3 and K2 are often combined. If you take warfarin, do not take a vitamin K supplement without speaking to your GP.

Food supplements should not be used as a substitute for a varied and balanced diet and a healthy lifestyle.
