A calcium supplement is needed, but remember to take a 2:1 of cal & mag as well as added vitamin D. These are needed to absorb and bind the calcium to the bones.

Also low estrogen will decrease calcium absorption, so beware of osteo in menopausal years.

Agree, Vitamin D is one of the most important ingredients that one should take with Calcium -- helps with the absorption process.

Also, there is Vitamin K which plays a crucial role in the movement, integration and retention of Calcium.

The key is taking the right form of calcium -- I won't give advise, but do your research because the are several forms of calcium out there that will deliver no benefits.

Cheers

The older you get the more important it is to take a calcium supplement
