Calcium Supplements

I’d like to get a second opinion on Ca supps. I’ve seen people recommending Coral Calcium but that really doesn’t do much more. If I’m correct, Cy mentions that Ca2CO3 (calcium carbonate - Tums) is about as good as anything else.

Then there are those who recommend Ca from dairy.

All said and done, is it more important to get a supp that has the correct Magnesium to Ca ratio than getting, lets say, Coral Ca?

Any thoughts?

Thanks,

Gary

Calcium from dairy is better than any other calcium. That ignores the other aspects of whether dairy is right for you. But as a calcium source, it’s #1.

Calcium citrate is the #2 source of calcium. It’s more easily absorbed by the body than other forms.

Coral calcium is way down the list.

Hey, there, chints! Long time, no speak. (grin)

I did a search on Google for calcium + bioavailability. I counted at least 6 different types of calcium where people were claiming THEIR form of calcium was the most bioavailable. It’s enough to make your head spin. But I did find a link that ought to answer all your questions about calcium and which form is most bioavailable. It even addresses the coral calcium issue. http://www.gnc.com/health_notes/healthnotes.aspx?ContentID=2819007&lang=en

The important thing with a good calcium supp is to make sure it comes with the necessary cofactors. My calcium supp has the following cofactors & synergists added: Vitamin D3, Vitamin B-6, folic acid, magnesium, zinc, copper, manganese, boron, oat straw, and TMG.

As far as dosage goes, shoot for 1000 mg (1g) per day for your mom.

Hope that helps. And as always, if you have any other questions, don’t hesitate to ask. (grin)

Hey Terry, thanks for the informative post. My problem with Ca supps is exactly what you stated. Everyone claims their product has more bioavailability. Not only that, high bioavailability may not mean much in terms of benefits.

Now, do that cofactors need to be in a certain quantity? Also, are there any brands that you can suggest.

Thanks for your advice.

chints, don’t worry too much about the cofactors. Everyone puts them in in different amounts. What you don’t want to do is purchase a supp that has just calcium in it.

Seriously, take a second look at the article. It resolved the issue of the different forms of calcium to my satisfaction.

Like my multi, I’m using the Life Extension Foundation’s calcium product. BTW, I’m using a calcium bisglycinate.
