Just test your blood levels before you start and then after 3 months or so. It's quick and cheap, and the only way to know whether the dose is right.

No, that’s literally what I was doing when I reached the excessive range: 5000 IU/day in winter with an indoor job.
This commonly repeated idea that everyone is deficient and you can’t overdose on 5000 IU/day is wrong.

Literally what I did.
Every time I explain this online it seems like the supplement people ignore what I wrote and just parrot the same “5000 IU/day and everyone is so deficient you can’t overdose” myth.
