Hi, Cheryl. This is a tough question, and I doubt whether our members here--any of them--would feel equipped to answer it. I sure don't.
But I also find it hard to imagine that hair and nails could change so quickly and dramatically. After all they have to grow, and I'd think any changes would show on the grown-out part, not overall. And also, does Vit D affect these things so directly? I know thyroid levels do, not so sure about D. Do you know what your D level was at first, and what it is now?
I suggest you see an endocrinologist for an expert opinion. This isn't really a neuro's bailiwick. Good luck.
I've never heard that vitamin D is beneficial to hair and skin. I would ask a doctor or pharmacist about it. I noticed you say you were prescribed vitamin D2. Any idea why? I ask because I believe it's been established that D3 is more effective in raising serum level of D. Just curious.
Thanks - I don't recall my D levels and haven't been retested since I started this regimen. I have read that brittle hair and dry skin can be a sign of low Vit D. Will have to find those sources again.
As for D2 vs D3, my neuro just said that D2 is what's common in prescription strength pills, and D3 is what's available OTC. I guess I did t question it any further....
Thanks for responding. I will look into other sources for the change and ask more questions.
