To me, understanding calcium needs and what happens with calcium supplementation is one of the most important things for people to understand not only for osteoporosis but for atherosclerosis as well. I take vitamin K2 every day, sometimes twice a day in two forms, MK-7 and MK-4. The reason is that after researching the topic of calcium, it turns out that calcium supplementation leads into having calcium where you don't want it, arteries, and not necessarily where you do want it, bones. I've stopped calcium supplements completely, as have all the women in my family, and I supplement with K2, D3, and magnesium. Where do I get my calcium? From food.

Here's a couple video interviews with Kate Rheaume-Bleue explaining the calcium paradox in here words. Thanks for bringing back this topic, Equinox, it's an extremely important issue for better managing health, and it's not being done correctly by the medical establishment (where have we heard that before?).
