That news hits home because I've taken two large Adcal tablets every day for over twelve years, supplied on prescription funded by UK's National Health.
An article in the British Medical Journal has accused academics and researchers in international osteoporosis foundations heavily funded by supplement manufacturers of wrongly promoting the use of these supplements. This is despite evidence piling up for over ten years that shows no positive effects on osteoporosis in the elderly. The main aim of managing osteoporosis is to prevent fracture. From 2002, evidence from randomised trials began to challenge the notion that calcium or vitamin D supplements alone or in combination safely reduce fracture risk. By 2010, 14 large studies with over 1,000 participants each showed results. Nine found no benefit, two found increased fracture risk and three found reduced risk. Source: Times of India.

The pills are thought to prevent osteoporosis, the bone-thinning condition that occurs in middle age which is particularly common in women after the menopause.
Calcium is a naturally occurring mineral which helps strengthen the bones while vitamin D is thought to help the body absorb it. But several major studies published in the last decade have found no evidence that adults taking these pills are any less likely to suffer bone fractures.
My osteoporosis was discovered when my femur shattered during a hip replacement operation. After tests on my bone density, these supplements were prescribed. Several years later, I tripped over a piece of furniture and broke my thumb joint. On another occasion, my ring finger broke when it got knocked. Chuckle. My husband moves during his dreams. He claimed a witch was trying to get into the bedroom through the picture above us and he was saving me. I raised my hand to stop his thrashing. Not funny at the time, but it makes me grin now. Must remember to keep my hands clenched.

Researchers say the benefits of the pills may have been hugely overplayed by their manufacturers.

This is another case of big businesses, foundations and governments working hand in hand.
What can I say? Business reign's supreme in our modern society.
Evidence for harm also emerged, including hospital admission for gastrointestinal symptoms, kidney stones, falls, hip fracture, myocardial infarction, and stroke. The United States Preventive Services Task Force has recommended against calcium and vitamin D supplementation for primary fracture prevention in 2013.
