Cal-in for vitamin D for severe osteoporosis?

Q) I would be grateful if you could give your view on taking Cal-in daily for added vitamin D. I have severe osteoporosis, and am at present taking Calci-chew-D3 Forte, otherwise I am having a ‘drugs holiday’. I have had many fractures.
J Cooper, Hoddesden, Hertfordshire

A) Cal-in is just another way of supplementing your diet with calcium and vitamin D. There is no reason to believe that it is any better at providing these than those sources available on prescription, such as Calcichew D3 forte, but it may be more palatable! In osteoporosis, while it is important to take these supplements, it is also important to take something to ‘strengthen’ your bones, especially if you have had several fractures. I presume you are having a ‘holiday’ from bisphosphonates, as continuous long-term use with these drugs is now not recommended and their use should be re-considered after 5-10 years.
