Product Overview

  • ECO-Friendly
  • Dietary Supplement

Source Naturals Coral Calcium / Magnesium contains a higher level of magnesium than the original Coral Calcium to provide the important alkaline minerals, calcium and magnesium, in a 2:1 ratio, as well as other trace minerals. An initial study on an alkaline mineral blend demonstrated an increase in blood alkalinity (pH) and buffering capacity. Proper alkalinity (pH) of the blood is critical for the overall health of the body. Source Naturals Coral Calcium / Magnesium is eco-friendly: it is harvested in Okinawa, Japan from fossilized (dead) coral and is not harmful to living coral.

Suggested Use

3 tablets daily.

Source Naturals Coral Calcium/Magnesium

Posted by Reviewer1526191 on Nov 06, 2007

As woman in my early forties, my doctor reminded me at my last check-up that I need to be taking a calcium supplement to help prevent osteoporosis. I had taken coral calcium before and liked it, so I found some on the iHerb site and ordered it. I had been having a lot of difficulty sleeping, but I swear that within 2 or 3 days of taking this I was sleeping like a log. When I mentioned that to my sister, who has a Master's Degree in Traditional Oriental Medicine and is a licensed Acupuncturist, she told me that magnesium helps with sleep. The only thing is that with this particular product, they recommend taking 3 tablets a day. That much magnesuim can cause diarrhea, and I had to back off to 2 tablets a day, but even at only 2 tablets a day, this product still delivers a great doesage of calcium and magnesium. I love this product and definitely recommend it.

Great but....

Posted by Reviewer2916228 on Jun 22, 2008

I like the tablets but if you have magnesium from another source (multi vitamin) you can get diarrhea. Make sure you know how much magnesium each supplement contains before you take the recommended 3 tablets. I just take 1 to 2 tablets instead of 3.

Coral Calcium

Posted by Reviewer2128490 on Apr 27, 2008

This formulas is a very well balanced blend for bone support. I have osteopenia and due to Vitamin D deficiency and hormonal imbalance. This formula has helped reduce some of the spinal pain I have. I am only 25.

Sciatica Saver

Posted by Reviewer2814708 on Oct 22, 2007

Source Naturals brand of Coral Calcium/Magnesium has saved me from a constant battle with sciatica. I'm a yoga teacher and although a regular practice always helped, it wasn't until I began using this product that I experienced complete freedom from the sciatica. I later read up on "sidedness" in the body and how various minerals can alleviate this type of problem. I'm grateful for such an excellent product.
