    Cool "Types" of calcium???

    Primal Blueprint Expert Certification
    What type of calcium is best taken by supplement? I see there are many different types: Calcium Citrate, Calcium Carbonate, Dolomite, Bone Meal or Oyster Shell, Calcium Gluconate, Calcium Lactate and Coral Calcium are all examples of types of calcium...very confusing and I heard some do not absorb without magnesium and vitamin D. I have also heard certain types of calcium gives you the "big C." I'd like to avoid that!

    I know I can get calcium from food sources, but if I were to take a calcium supplement, what type is best?

    Thanks for any helpful info! :-)

    From the fairly extensive research I had done before selecting the supplements I would take, I found that calcium citrate is generally regarded as the most easily absorbed and bioavailable form of calcium. Here is one comparison between the citrate and carbonate forms:

    and here is a general info page about calcium:
    http://ods.od.nih.gov/factsheets/calcium.asp

    I personally use the following:

    Now Foods, Calcium Citrate tabs (with Magnesium, Zinc, Copper & Manganese)
    http://www.iherb.com/Now-Foods-Calci...blets/472?at=0

    Be aware that these are fairly large tablets (but well-shaped, so at least for me, easy to swallow), so if you need capsule form, they're also available, but more expensive per unit of calcium ($0.23 per 600 mg Ca, vs. $0.10 per 600 mg Ca for the tablets):

    Be sure to take magnesium with your calcium, for proper Ca absorption. The optimal ratio of Ca:Mg to take varies, depending on which source you refer to; it can range from 1:1 to 3:1; I aim for 2:1 (which is the ratio in the tablets above).

    Beware of calcium in the form of MCHA (microcrystallinehydroxyapatite); this form is usually derived from animal bones, which can contain heavy metal contaminants. I try to avoid MCHA altogether, to be safe.
