Bought calcium supposedly for increased weight loss during working out (or cutting) phase (read in a few fitness books & also on Martin Berkhan's Leangains) Feel like it is effective, can't really tell. Always look for more bio-available form (easier absorbed by the body) eg citrate and possibly with Vit D3 (not D2) and try to take with meals (it requires a more acidic environment to breakdown). Adding Magnesium to the stack at a different time would helpful too. Careful if you are taking calcium blocker for high blood pressure as there might be interactions. Also it might make your thyroid sluggish.

Good, dependable calcium supplement

I really like Natural Factors as a trustworthy brand. This is a good quality, well-absorbed form of calcium. It's not as fancy as some of the professional brands, but I like it as a cheaper alternative and will continue to buy it.

Without Vit. D; wish it was without soy too.

It's hard to find calcium citrate without vitimin D. Would prefer it didn't have soy since from what I've read it works the same as estrogen. Having a cancer that feeds on estrogen, soy is something I should not have.

I've used this for a time. Good product. Calcium citrate is hard to find in Norway, so I turn to Iherb.

great calcium

The only thing that would make it better is a dosage of 300mg instead of 350
