Vitamin D side effects?

I didn’t have any health reasons. I heard quite a bit earlier on in covid that vitamin D could help quite a bit, so I took some. It didn’t seem like a lot, or too little. I went about 6 to 8 months (not sure exactly) and had zero side effects of it.

I stopped taking it towards the end of September, when I started feeling off. I ended up not taking it for about two months. I had several test done, including a blood panel. My calcium level was completely normal, but still all the side effects.

As of now, I have an appointment with a neurologist in February, but all tests have been completely normal, so the only difference is all of this began 19 days after the second vaccine. And it took over a month for me to even realize that.

I questioned vitamin D because I’m attempting to eliminate and question anything I’ve been doing differently at all, and this seemed like a possibility.

You're asking all the right questions, Tyler. I'm glad to hear that you've scheduled an appointment with a neurologist.

Headaches are a common side effect of the COVID-19 vaccination. However the typical onset days after the vaccine not 2.5 weeks as in your case. Other symptoms can also occur, including nausea and sensitivity to light. You can read more in this article:

According to Mayo Clinic, taken in appropriate doses, vitamin D is generally considered safe. However, taking too much vitamin D in the form of supplements can be harmful. Children age 9 years and older, adults, and pregnant and breastfeeding women who take more than 4,000 IU a day of vitamin D might experience:
- Nausea and vomiting
- Poor appetite and weight loss
- Constipation
- Weakness
- Confusion and disorientation
- Heart rhythm problems
- Kidney stones and kidney damage

The article also lists several medications that interact with Vitamin D. See the list here: https://www.mayoclinic.org/drugs-supplements-vitamin-d/art-20363792

Tyler, you were wise to stop vitamin D until speaking with a health professional. I'll be interested to hear what you learn from the neurologist.
