I had run out of whatever brand of coral calcium I used previously and so purchased this Lally Naturals Coral Calcium. Since I started taking this I feel better. I do not like calcium tablets and these capsules do the trick for me as they are very easy to swallow. Coral calcium is recommended over other calcium forms for anyone who might have heart issues as we do not want the heart to get too much calcium, but still want a good supplement for bone health and this has many benefits besides just calcium, such as minerals included and can help with alkalization of the body. I also had hyperparathyroidism and this coral calcium will keep my levels where they should be without any tingling sensations noted from being low on calcium. I was getting some numbness and tingling in arms at night when taking regular calcium carbonate because I didn’t want to take too much. I will purchase again when I get low.
