vitamin d deficiency
"After my wellness checkup and blood analysis, I was told by my md to start taking Vit. D3-2000 daily.

I took it as recommended for 2 days and I noticed that I was experiencing dizziness, tiredness and really bad cramps in my hands, feet and legs.  I thought that I was dehydrated and drank more water.  The cramps kept getting worse and I also started having increased palpitations and more dizziness.  As the only change I had made in my daily regimen was taking the D3, I decided to stop taking it to see if it might be the cause.  Sure enough, these symptoms disappeared.  So, why are we being told to take this?  Several of my friends and family have been advised to do the same lately.  Is it a new "health" sham?"
