Product Information

Our convenient, one-a-day Vitamin D3 400iu tablets provide The Department of Health-recommended amount of Vitamin D all UK adults should consider taking throughout the winter months.

This level is an excellent choice if you want to top-up your vitamin D intake or combine it with one of our comprehensive multivitamins, most of which already supply 400iu vitamin D3. If you get very little sun exposure, we recommend our higher strength Vitamin D3 1000iu product.

Our pure-grade Vitamin D3 400iu delivers the preferred form of vitamin D (cholecalciferol or vitamin D3), which is naturally synthesised in the body when sunlight directly hits the skin. The body absorbs vitamin D3 much better than the D2 form (ergocalciferol) made from plants.

We've chosen to provide this strength of vitamin D3 in tablets, not capsules, since this product is recommended as a top-up level, best taken alongside a multi with magnesium, zinc and vitamin K, which all increase vitamin D absorption.

We manufacture and package our Vitamin D3 400iu in UK factories working to Good Manufacturing Practice (GMP) to ensure our quality standards are always met.

Since Vitamin D3 400iu is made from cholecalciferol, it's suitable for vegetarians not vegans. However, if you're looking for a plant-based alternative, you can try our Vegan Vitamin D 1000iu.

Still unsure of which vitamin D3 product to choose? Don't worry. We have a team of friendly Nutrition Advisors on hand to help you pick from our extensive Vitamin D3 offerings. Simply click the 'Nutrition Advice' button located at the bottom right-hand of our website to start a live chat.

I''m told we need Vit D especially in the winter. I don''t know if it is effective. This is only the 2nd time I have bought it from NB. I am confident that the other two products I have purchased for years from Nature''s Best are effective.

A combination of osteoarthritis in my hip, and the Covid pandemic meant I was hardly getting out at all. We all know that vitamin D is the sunshine vitamin but I was surprised and pleased with how much Vitamin D lifted my mood. My get up and go had got up and gone !! Just a week after starting the tablets I felt much better. I was amazed actually, as I had been rather sceptical but thought that I would give it a try. Very glad I did.
