Personal anecdote, Vitamin D is a horrible placebo.

I have been trying to increase my Vitamin D levels for 15 years now but I just can't tolerate this supplement.

  Lower dosage: ~1000 IE -> side effects come after around 3-4 days of daily intake.
  Higher dosage: ~5000 IE -> side effects after a few hours.

I tried following most advice over here in the past but it did not work: https://vitamindwiki.com/Vitamin+D+Cofactors+in+a+nutshell

I'll just live with my low blood Vitamin D levels.
