I'd like to warn everyone about Vitamin D. Taking a daily megadosage of some cheap Amazon Vitamin D I eventually reached twice the upper reference range value in my blood. I couldn't sleep anymore and went crazy and irritable and had constant diarrhoea. It's one of the very few micronutrients that can actually harm you in excess, besides vitamin B6, which is also known to cause permanent damage. You probably do not need and should not supplement vitamin B6. https://en.wikipedia.org/wiki/Vitamin_D_toxicity#Signs_and_symptoms https://en.wikipedia.org/wiki/Vitamin_D_toxicity#Signs_and_s... https://en.wikipedia.org/wiki/Megavitamin-B6_syndrome#Signs_and_symptoms https://en.wikipedia.org/wiki/Megavitamin-B6_syndrome#Signs_...

How much was the dose? I'm taking 5000 IU almost every day. My levels have never tested above the reference range though and I rarely have diarrhea.

  Several 10.000 a day for months.

    That's really excessive. In my country, the standard of care for low Vit D is a bolus dose of 60,000 IU once a week for a month, and then switching the 60K IU dose to once a month.

      I half believed those pills from amazon were fake pressed inert dust and lacked the knowledge I have now.

        So you were assuming it was under dosed?

        No I was just dumb and not thinking too much at all. Any high or non-sane vitamind D dosages should be accompanied by regular blood tests.

D3 is really a hormone. You are showing the classic symptoms of it becoming too high. If/when this happens, discontinue supplementing for a few days and then you can resume at a lower level. Once you understand what too high feels like, you can easily adjust. You may need a different level in different seasons of the year (because the sunlight varies) or if you change latitude (for the same reason). Your needs may be very different to the people around you.
