Perfect Calcium Supplement for Our Dog's Food!

We started using Nutricost Calcium Carbonate as a replacement for NOW Foods Calcium Carbonate Pure Powder, which has been out of stock for a while. We’re so thankful to have found this high-quality alternative for our Portuguese Water Dog, Kaia! We mix a small amount into her food as part of her balanced diet, and it’s been working perfectly. The powder is unflavored, pure, and easy to use. It dissolves well and integrates seamlessly into her meals. The 1.1 lb size is ideal for consistent use and offers great value. Nutricost has exceeded our expectations, providing the same high standards we were used to with our previous product. If you’re looking for a dependable calcium carbonate supplement for your pet’s nutrition, we highly recommend this one!

Great way to add calcium if you don't eat dairy

I use this calcium supplement to improve my bone density. I don't eat dairy. It is a quality ingredient that I add to my morning smoothie. It mixes easily and has no taste. Anyone of older age with a calcium deficiency would benefit from this supplement, in my opinion. In combination with vitamin D3, this has helped me stay active. The package was well sealed.

worth it

For me this is an affordable way to get my daily dose of calcium. It lasts a very long time and it's just calcium powder wiht no added flavors or other things that I don't need or want to take. I find it better than the calcium and vitamin D combo that my doctor prescribed which has added flavors and sweteners. I take the vitamin D separately.

Excellent quality, and much easier to swallow than capsules.

I didn't know that calcium powder existed and I loved it, because I had difficulty swallowing calcium capsules, which are always huge. The powder is very fine and white (it doesn't look like it in my photo, but it's absolutely white), it has no smell or taste, and it's very easy to ingest mixed with any drink.

For healthy bones, nails, teeth

I do not take dairy products because of an intolerance to them. From there I also have a calcium deficiency and progressive osteoporosis. I have been taking this calcium carbonate for some time. It is pure, easily digestible and without unnecessary fillers. I fill it into capsules and so I can determine the dose myself, according to my needs. My parathyroid hormone has decreased, which shows that I am absorbing it. I really hope that it will also affect my bone density, which I will check soon. Thank you Nutricost for the pure supplements, at an affordable price!

Great

This calcium carbonate powder is a great value and comes in a generous size. It’s fine, unflavored, and easy to measure, which makes it convenient to use. After using it in my diy toothpaste, I’ve been happy with the quality and how well it fits into my formula. Good price, clean product, and I would buy it again.

Love it

The main reason i got it was to make a toothpaste with it. It turned out great. i havent tried it as a supplement yet since i have plenty of calcium rich foods. Love the fact that it has no other ingredients in it. Quality seems high and its easy to package in capsules

best bang for the buck

this was the best bang for the buck, also was a bonus that it's from the brand I usually buy sups from. tastes pretty much like nothing since I usually mix it in with my other supplements. been taking for over a month now. can't really tell if there has been any bone improment or benefits. iv just been taking it just in case I'm deficient in it.
