"Trying this form of calcium confirmed that coral calcium is not as effevtive as calcium citrate. Several physicians had advised that this was the case, but using this product demonstrated their statements to be true."

"Making the calcium plus product in a capsule takes care of the biggest problem I had with taking calcium pills...too hard to swallow. Having these in capsule form is perfect...no more hesitation when I take my calcium ..."

"Two capsules give 700mg elemental Cal, right? Your body can absorb only 350mg at a time, according to Nutr 100 at the U of A. Which means: one-a-day will do, though I take one at breakfast, one at supper. Also, the Mag content means: combine this product with Magnesium Ultra and you need only take on of those Mags a day, the rest of the Mag being made up with BY THIS PRODUCT! Why is this exciting? Because we need Cal and Mag for bones and our brain, yes our brain! This is the most inexpensive coral calcium on the market, and I look askance at the retailers that are charging double and triple the price for the same thing. Buy this, it's a steal!"

"I have Lupus and have taken Prednisone for seven years. Prednisone is known to leach calcium from bones. I also have osteoperosis in my family. I have taken this Coral Calcium since starting on Prednisone and have not had any bone loss. I am sure the quality of this calcium plus the magnesium is the reason. It is important to take at least two capsules a day, but the price of these minerals is very reasonable."

"While there is a lot of hype when it comes to Coral Calcium, I still find it's a superior product for achieving Calcium & Magnesium, because it is biochemically more active and comes with over 60 trace minerals. This is a great value at this price."
