For the last two or three years I have been using this product. In listening to a nutritionist I heard magnesium oxide has about a 4% absorption rate. I did the research and found this is true. This is the main magnesium ingredient in Bone Up.
Most calcium / magnesium supplements use the magnesium oxide, at least 80% oxide. This form of magnesium must be very cheap. The studies are self evident that the oxide version is a very poor choice.
So I tried magnesium glycinate. Immediately my body changed, the aches and pains in my back and neck went way down. The muscles around my face loosened up - tear ducts working better so eyes aren't so red, bags decreased significantly, chewing muscles from TMJ not spasming as much.
Essentially, I have been taking Bone Up and been magnesium deficient. Coral calcium is no better for me. I will never order Bone Up or coral calcium again.
I have gone to a food source calcium / magnesium and am supplementing with the magnesium gycinate. The difference is very significant.
Hopefully this will be helpful to people. Just because Jarrow puts a lot of ingredients in their products does not mean it is good.

What you want is Calcium citrate. Microcrystalline hydroxyapatite absorption is below 22%. Calcium citrate absorption is about 42%.
