Vitamin D3 2000iu, Maximum Strength

Our maximum strength Vitamin D3 2000iu is an excellent choice for anyone wishing to optimise their vitamin D3 intake throughout winter or looking for a vitamin K-free 'D'. It's also popular amongst the five groups identified by the Government at risk of low vitamin D, such as those with specific bone health concerns or the over 65s.

Our pure-grade Vitamin D3 2000iu is the strongest in our vitamin D range, providing a huge 2000iu (the equivalent of 50ug) in each taste-free, easy-to-swallow capsule.

Our formula contains the preferred form of vitamin D cholecalciferol or vitamin D3 , which is naturally synthesised in the body when sunlight directly hits the skin. Vitamin D3 is more bioavailable (readily absorbed) than the D2 form (ergocalciferol) made from plants.

We've chosen to suspend our vitamin D3 in a quality sunflower seed oil to support optimal absorption. Capsules are much better suited to oil-based materials, which is why we've decided to use them over tablets.

Our formula is made in UK factories working to Good Manufacturing Practice (GMP) to ensure our quality standards are always achieved.

Vitamin D3 2000iu comprises cholecalciferol, which is suitable for vegetarians but not vegans. If you are looking for a plant-based alternative, try our Vegan Vitamin D 1000iu, made from vegan-friendly lichen.
