Vitamin D side effects?

Posted by tylerk @tylerk, Dec 28, 2021

For about the past year, I’ve been taking a vitamin D supplement, mostly as a precautionary measure for covid. About 2 and a half weeks after I got the second vaccine, I started having eye flashes (ocular migraines) and a light headed and spacey feeling. The spacey/foggy feeling was constant, and eye flashes about once a week on average.

I decided to stop taking supplements, for approximately 6 weeks. The symptoms didn’t seem to be effected much. There were several people that had colds I was around for Christmas (not covid), so I took about 7,000iu’s total daily of vitamin D for about 6 days. I never got sick, but the lightheadedness seems to have ramped up slightly, and have had eye flashes every couple days.

Has anyone else experienced these symptoms as a result of taking vitamin D. As a side note, I’m doctor had me get a brain mri to be sure nothing is going on (still waiting on results)

@cjhover6342, what did you learn from your doctor? How are you doing?

I'm on vitamin D because my serum levels go down if I don't take it. I did supplement it at a higher level recently (an extra 10k IU a week). But it's back solidly in normal range at 40 .

My multi has the standard 2000 IU, but that doesn't always help enough. May be my kidneys or the hyperparathyroidism. My eGFR has plummeted 30 units this year (still normal, though), so I'm guessing kidneys. 🫤

But if you're having migraines and you got the COVID vaxx and boosters, I'd ask for cardiac eval.

I had a nuclear stress test in February 2021, as I was having intermittent HBP. I was also 51, so my insurance paid for it as part of standard "old people" screening. They also suggest colonoscopy at that point.

If you're over 50 and haven't checked your heart, it's not a bad idea. You could be having intermittent blood pressure issues that aren't a problem at the doc's office. Esp. if you don't see docs often.

My screening caught my 5.1 cm ascending aortic aneurysm.
