Were you taking hard tablets? And were you taking them with a fatty meal?

Those are both very important. I take a Vitamin D + K2 softgel with a meal that has some fat in it.

Costco sells D3+K2 softgels! Great price, of course.

I started taking them at the recommendation of my podiatrist after I broke my foot last winter (third metatarsal fracture, specifically, ouch).
