Has anyone else experienced any vitamin D toxicity symptoms?
I started supplementing with D3 caps about 18 months ago. My levels went from about 35 up to my current level of 120nmol/L. I've been experiencing some weird sensations over the last few weeks that I attributed to excess thyroid medication (funnily enough the symptoms of thyroid med overdose and vitamin D overdose have quite a bit of overlap).
I've experienced dizziness, headaches, insomnia, heart disturbances (palpitations, sensation of hard beating, mild chest pain), irritated eyes, and generally feeling a bit weird and spaced out. I stopped taking thyroid meds a few weeks ago for other reasons, but these symptoms have persisted.
So I stopped taking the vitamin D a week ago, and the symptoms have started to subside slowly. I probably should have twigged when I saw the lab result, but sometimes it takes a while for things to sink in.
This blog post was also interesting, confirming a lot of my experiences:
Anyway, no more vitamin d supplementation for a while... it's summer in Sydney now.
