This is a good Vit D product that I started to purchase for the last 1year. My mother-in-law went for her bilateral knee replacement and the orthopaedic surgeon prescribed daily Vit D supplements to speed up her recovery. We have been continuing her on the Vit D since then. Caltrate products are well formulated and comes from Australia which is our trusted country of manufacture. The product comes very well packed in bubblewrap, seller is v reliable and responsive.
