Vitamin D

This is the one supplement the NHS openly suggests most people in the UK consider, at least from October to March, because you simply cannot make enough from weak winter sun. That makes vitamin D unusual here: not a wellness fad, a sensible seasonal top-up. Most picks are D3, which is the form the body uses; some add K2, which is fine but not essential.

Common questions

How much vitamin D should I take?

The NHS suggests 10 micrograms (400 IU) a day for most adults over autumn and winter. Many supplements sell much higher doses; more is not automatically better, so do not go wildly over without a reason.

D3 with K2, worth it?

K2 is thought to help direct calcium to bones. It is a reasonable addition and does no harm, but the D3 is the part doing the heavy lifting. Do not pay a big premium just for the K2.
