Calcium / Vitamin D

Spotted another of your posts on calcium and blood pressure. Well dug out my test notes from Biolab, I had higher than normal serum calcium and was massively vitamin D deficient. I never had these results re done, albeit recently ran out of vitamin D supplement and my hair loss has gotten worse. Wonder if there is any link to my high protein, potential kidney issues from this. I also took potassium once and think it helped with my balance. Hmm? Any thoughts?

Ps - just been on my exercise bike, about a minute in I got that metallic taste, and after 5 mins or so I was itching like absolute mad!! Any ideas?
