It takes a lot of things besides calcium to help keep bones solid, and to rebuild if you have lost bone density. I believe that Bone Solid is a very good product.

I am surprised to read in the product description:"vitamins K1, K2 and D3 are added in generous amounts". Country Life emailed me that they actually include ONLY 11mcg of the expensive proven form of Vitamin K2 (MK7) menaquinone-7. MK-7 is vital in getting calcium into the bones instead of between the joints where it will add to arthritis. You need 45mcg to 200mcg per day. K2 menaquinone-7 is the only form of K2 proven by research to build strong flexible bones. Research, especially by a Dr in Holland, shows the other forms of K2 are just not proven to build bones. K1 is extremely cheap and does nothing more than clot blood, while K2-menaquinone-7, being made by fermentation, is the hardest of all to come by, and is very expensive: that's why they only have 11mcg! I also DO NOT appreciate that these have magnesium oxide in them. This is the cheapest, stingiest form of magnesium and is not well absorbed. - This and the stingy amount of MK-7 make me very suspicious of the good intentions of this company. They are a little more expensive than the Now brand Bone Strength - 9.21 cents compared to Now's 7.6 cents. BoneSolid has a lot more Boron. Taking either of these companies' bone builders, you will also need seperate K2 in its MK-7 version. Good news is that Iherb sells other brands that tell you exactly how much K2-menaquinone-7 they have: Drs. Best Calcium Bone Maker has 80mcg of Mk-7, Alive has 100mcg of Mk-7 Garden of Life has 100mcg of Mk-7.
