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

No additives, the amount in the bottle means I don’t have to replace the pills frequently and the price is good.

Very good product..

I was glad to find this calcium supplement without D3 -- just calcium alone. The math isn't right when the pill contains both, at least not for the amount of D3 recommended by my doctor. I get the D3 separately too, which makes it easier for me.

Seem to work, no broken bones

Is exactly as advertised i can't speak to its properties as an antacid.As i'm using it for an off label purpose , but it's doing exactly what it should do

Just what the doctor ordered. Perfect !

We take 1200 mg of Calcium daily for each of us. Easy to swallow. More cost effective options are available out there for the same thing.

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.
