This is the highest strength an adult would normally take long term, and it sits exactly at the published upper level rather than above it. That makes it the strong option rather than the excessive one.

Most people topping up through a British winter do not need this much – 1000iu is the usual everyday choice. 4000iu is for a specific reason: limited sun exposure, a low result, or advice you have been given.

Solgar's are Vcaps in 60 and 120 counts; Lifeplan's are tablets in 90. Work out the cost per capsule rather than comparing pot prices, because the counts differ.

If you need a vegan version, check the individual product – most D3 is derived from sheep's wool, and lichen-sourced vegan D3 is stocked at lower strengths.

With food containing some fat, since it is fat soluble. And check everything else you take for vitamin D before adding this – multivitamins, cod liver oil and calcium products commonly contain it, and it accumulates.

If you are pregnant, giving it to a child, or on prescribed medication, ask a pharmacist or your GP first. Your GP can test if there is reason to.

FAQ

Is 4000iu safe to take daily?

It sits at the upper level UK guidance sets for adults from supplements. That makes it the strong end of normal rather than excessive, but it is worth having a reason for it.

Do most people need this much?

No – 1000iu is the usual everyday choice for topping up through the winter.

Can I take it with other supplements?

Check them for vitamin D first. It appears in multivitamins, cod liver oil and calcium products, and it accumulates in the body.

Is there a vegan option at this strength?

Check the individual product. Most D3 comes from sheep's wool, and the lichen-derived vegan version is stocked at lower strengths.
