The trouble is that supermarket multivitamins don’t contain the amount of Vit D required to make up for lack of sunlight in the UK; you need a high-strength D tablet in addition to the D in your multivitamin

(The UK govt recommends a 100IU supplement of Vit D per day and this is what most multivitamins provide, but current understanding is that an adult needs 1000-2000IU total per day, which is hard to achieve from sunlight and food in the UK)

Quite right. I recently started taking multivitamins, and was told by the doctor I need to take 800IU per-day (based on my blood levels) of Vitamin D (I have "Olive" skin), the multivitamin provides only half of that (400IU/10uG).

You shouldn't double up on the multivitamin or you'll be overdosing on other vitamins it contains, so an additional Vit D is required.

> The UK govt recommends a 100IU supplement [...] current understanding is that an adult needs 1000-2000IU

The NHS recommends you consider taking 400IU, and not more than 4,000IU: https://www.nhs.uk/conditions/vitamins-and-minerals/vitamin-...

(That page also says 400IU is what adults need, do you have a source for your 'current understanding' by any chance?
