Hi Sharon / Bex

thanks for the info. I will contact Biotics and find out what the D3 is derived from before ordering. I think the drops might be more practical.

Sharon - have you noticed any side-effects from taking the Vit D? Lifting of fatigue? I noticed that my heart rate got lower, from the 70s down to late 50s-early 60s, which I'm not sure is a good thing. Apparently calcium regulates the heart or something. Or it may be I need to increase my thyroid dose. So frustrating not knowing what's what.

I am having a bone scan tomorrow, so all will be revealed then....

thanks again
Nicola
