This is the only calcium that doesn't bother my stomach. You can divide it in half because it's a big pill. Most of all, Sams changed the color from pink to white. We have people with red dye allergies that had to stop taking the product. But, since it's now white they are really happy. I really appreciate the large number of tablets you get in a bottle.

Hard to rate them. They look like the brand name. I guess they will be fine if they are absorbed well, but won't know without medical testing!

Due to cancer treatment I must take maximum amounts of supplements, calcium being one of them. Supplements can be costly. Thanks to Members Mark supplements it’s not such a gouge in the wallet. I appreciate that.

I have to take 4000 mg of calcium a day due to thyroid surgery. I was left with half the thyroid. I was happy to find the calcium dosage so close to my needs at such a great price! This bottle should last awhile even at taking four a day! At this price, ill keep buying it.

Used this calcium for many years, no problems

Essential mineral especially at our age!

I need calcium supplements and these have a low price and the same ingredients as high end supplements.

Great product great price

Great supplement for your bones!

It’s worth the price. It’s working.
