Kirkland Signature Calcium Citrate 500mg (500 Tablets)

Love this vitamin. The citrate in the calcium makes it far more absorbable than most calciums and right away my nails got stronger and started growing. It has gotten harder to find the calcium, magnesium and zinc combination that I have always taken because of a recommendation my doctor made many years ago. I was so happy to find it with the citrate and then huge bonus D3 is added! This couldn't be a more perfect combination for me and then to find it in such a huge bottle at such a reasonable price! I was stunned! They couldn't add one more thing to make it anymore perfect for me! Thank you Kirkland and Thank you Amazon! I'll be ordering this again and recommending to my friends and family!

I bought this product based on reviews. I have also read that calcium citrate is the most absorbable form of calcium. I have been taking these pills for a month now and I'm hoping that they are indeed doing what they are supposed to do. It doesn't say anywhere in the label that it has to be taken with meals but for me, I've found out that if I take it with an empty stomach, it makes my stomach churn and I feel nauseous. It gives me diarrhea too. If I take it with meals, though, none of that happens. For the price and quality, I think this is the best Calcium pills in the market right now.

Listen to my wife. I was having leg cramps at night so bad that I would bolt out of the bed to stretch my calves because the pain was so bad. My wife instantly became an internet diagnostician and told me "You need to take calcium."...I love my wife, so I am always taking whatever herb or tea that she thinks will make me better so I ordered these pills. OMG! As long as I take these pills I don't get leg cramps at night anymore. If I run out of them about a week later the cramps come back. I'm sold, I'm going to keep taking them. I guess since I am no longer gnawing on the bones of my enemies I need something to put calcium back in to calm my muscles. Who would have figured?

I love the convient of in line

I was reluctant to switch from the brand of calcium carbonate I’ve been using faithfully for the past, oh, 20 years or so. But I finally decided it was time to try calcium citronate, because it’s reputedly easier for the body to absorb—which is a super important factor for bone health in older people, especially women. In the past, I tried calcium supplements on their own, but found they caused constipation. For a while I was trying to offset this effect by adding a separate magnesium supplement, but it was difficult to strike the right balance. Ultimately, I settled on a reputable vitamin brand containing nicely balanced proportions of calcium-magnesium-zinc. I was reluctant to upset this balance by trying a new brand. My old brand contains 333 mg calcium carbonate to 133 mg magnesium. By contrast, each pill of the Kirkland brand contains 250 mg calcium citronate to 40 mg magnesium. The proportions sounded really off to me, but I’m glad I tried Kirkland’s product. It does not cause constipation—whew!, and I will be getting better absorption and therefore bone health with calcium citronate. Some people experience the pill as difficult to swallow, but I have not had any problem swallowing these tablets. To get 1000 mg/day, I take two pills with my morning meal and two with my last meal of the day. (Each pill is 250 mg.) I find the price reasonable as well.

We have been using this exact product for years but now live almost an hour from the nearest Costco. I was so happy to find this on Amazon at a fair price. My doctors agree calcium citrate is the best form for absorbency and all my lab tests show my blood calcium levels are great. I am in my 60s so maintaining calcium levels is a priority to maintain strong bones. Surgery I had a few years ago could only be done if my 'bone density' was at a high enough level and the tests showed it was fine. I will continue to use this supplement for life.

Effective product. But take note, as I have not yet seen this clearly addressed: Calcium Citrate contains only 21% of elemental calcium (calcium that is actually used by the body). Hence, (250 mg pill x 21 %) = 52.5 mg of usable calcium per pill. So depending on your needed calcium intake (or lack thereof) you may have to take 20 pills per day of this product to meet the above 1000 mg daily requirement. (And any overconsumption of the other listed ingredients contained per pill, may have to be considered.) Thus, in a real world application, based on one’s elimination diet (e.g. lack of dairy, lack of nutrients in hybrid vegetables, etc.) 500 pills will not last long, at all. I suspect many are under dosing calcium citrate based on a lack of knowledge and misdirected fears regarding calcification. If you lack calcium in your diet, you will need to make the necessary supplemental adjustment. Hopefully this clarifies for some.

This is a product that I've used for years. It's inexpensive and tastes good. if you live in a hot, humid climate, you should keep it in a dry place to avoid discoloration.

I cant fault the product but the packaging wasnt up to scratch. The lid is made of a solid breakable plastic that got busted in transit. Suggest bubble wrap on the lid

Good quality
