[Supplement / Vitamin] Calcium and Vitamin D [My Dosage] 250 mg calcium 3 times daily [Function] 
As a coeliac I have osteopoenia (thinned bone) so calcium and vitamin D are to help that. There is conflicting evidence whether calcium has much effect on osteopoenia or osteoporosis, but until something better comes along, I'm taking it.{Note: 5 years on I've stopped taking a calcium supplement as it appears that they can contribute to arterial calcification (and you don't want any of that). I now focus on magnesium and vitamin D status and lifting heavy weights to strengthen my bones).
