I don't think when you take it makes any difference (though you might want to take it together with food that contains fat for better absorption).

Multiple people such as gwern and Seth Roberts found that the timing makes a difference for them.

That's true.

What I meant is that blood levels of vitamin D are fairly stable and for the purposes of reduction in mortality it shouldn't matter when in the day do you take it. However side-effects, e.g. affecting sleep, are possible and may be a good reason to take it at particular times.

I don't think it's clear at all the the purpose of the reduction of mortality is different than the purpose of sleep quality.

Vitamin D does do different things but I would estimate that a lot of the reduction of mortality is due to having a better immune system. Sleeping badly means a worse immune system.
