400iu is 10 micrograms, and it is the amount UK guidance has long referred to as a daily supplement through autumn and winter. It is the modest, everyday strength rather than a corrective one.

It suits anyone topping up sensibly, and anyone who would rather not take a large amount of a fat-soluble vitamin. If you have been told your level is low, your GP will advise on something higher.

D3 is the form the body makes in sunlight and is better used than D2. Most D3 comes from sheep's wool, so vegan D3 is grown from lichen instead – Viridian's vegan 400iu is that.

They also make an organic vegan D2, which is the plant-derived form. D3 is generally the better choice where a vegan version is available, and it is here.

With a meal containing some fat, since it is fat soluble. It accumulates rather than being passed, so check any multivitamin, omega oil or calcium product you already take before adding it.

For children, the amounts differ and the products are specified accordingly – ask a pharmacist rather than splitting an adult product.

FAQ

Is 400iu enough?

It is the modest everyday strength referred to in UK guidance for autumn and winter. If you have been told your level is low, your GP will advise on more.

What is the difference between D2 and D3?

D3 is what your skin produces in sunlight, and the body uses it more readily. D2 comes from plant sources.

Is there a vegan version?

Yes – lichen-derived vegan D3, and an organic vegan D2. Ordinary D3 comes from sheep's wool.

Can I give this to a child?

Amounts differ for children and there are products specified for them. Ask a pharmacist rather than dividing an adult product.
