Why did they change it?
I began using this product's predecessor, Nutra-Life Super Calcium Complete, in 2003 when I found I other calcium supplements gave me indigestion. Our local pharmacist recommended I try it because it the Hydroxyapatite was supposed to be more easily absorbed than calcium carbonate (I think). The change worked a treat, and it became my calcium supplement of choice until Nutra-Life changed the product and introduced the "Gold" version. I don't have a problem with the actual product: I have a problem with its size & shape. It seems to be bigger and fatter than its predecessor, and I can't swallow it easily. My mother calls big capsules "horse pills", and that is what these are -- they are huge! As a result, I will not be ordering it any more and shall have to find another Ca supplement :(
