Just in case you encounter this not-really-news.

"Analysts assert bone health advocacy groups are funded and influenced by industry.

Despite more than enough data that strongly suggests calcium and vitamin D supplements have little to no effects in preventing osteoporosis, and may even pose harmful risks to consumers, both the U.S. National Osteoporosis Foundation (NOF) and the International Osteoporosis Foundation (IOF) continue to recommend these products, stated Andrew Grey, MBChB, and Mark Bolland, MBChB, from the University of Auckland in New Zealand.

Both NOF and IOF are heavily funded by supplement and supplement-enriched food companies, they pointed out in an analysis in BMJ."

The article rants against calcium and Vitamin D supplementation. Calcium we know about (does nothing for bones, raises other risks).

I'm going to conjecture that the studies they relied on to dismiss Vit.D didn't use dosages sufficient to reach therapeutic blood levels. The complete omission of any discussion of K would be consistent with that cluelessness.
