What time of day are you taking it?

Anecdotal, but several accounts I heard from people I know (and some I’ve read — even in this HN discussion, but the most n=1 scientific is gwern) indicate you need to take the vitamin D early in the day or it would harm your sleep quality. It also makes sense biologically, given that you need sunlight to generate it yourself.

Again, anecdotal - but detrimental to my sleep if taken after midday. If I can’t take it until 10am, I skip that day
