Nature's BlendPure Calcium Carbonate 600 mg 100 Tabs (1684)

Only calcium carbonate 600mg I could find that did not have D3 in it.

Exactly what the doctor ordered.

Excelente producto lo recomiendo muchísimo precio y calidad increíbles

your body will only utilize calcium as Carbonate, any other content is a waste of money...

Easy to swallow. Take with D3.

My husband takes magnesium citrate for leg cramps which worked fairly well. I read that calcium is needed in combination with the magnesium and so he tried it and said after a few days that he noticed a major improvement and now doesn’t need to take as much magnesium which would sometimes cause an upset stomach.However - for men considering taking calcium please read the well documented research papers on calcium (and potassium) supplements causing prostate cancer! You need to be taking less than 2000mg a day of calcium so don’t pop these like candy! My husband is taking two a day. One morning and one night with his magnesium.I have also advised him to look for a new protein powder as he uses whey and that contains a lot of calcium too - not to mention the calcium he gets from cheese and leafy greens and other sources. So if you are a guy, do your research (good but scary article on the nih.gov site) as calcium and potassium over supplementation without question leads to prostate cancer.But if you have leg cramps and you take magnesium add in a calcium tablet for better absorption and you may also notice a big improvement.

Had a hard time swallowing the tablet, it is rather a large tablet. Hey I am a petite person so I need smaller tablets. It does the job, no complaints so far. Might have to cut in two and take separately. Money talks. :)

great supplement for my system
