What is Calcium Carbonate?

Calcium is an essential mineral that the human body cannot produce on its own that helps fortify the bones & teeth. Because the human body cannot produce calcium, it's necessary to acquire it through diet. Calcium carbonate is a type of calcium salt found in many food products, tooth pastes, and antacids.  


Calcium fortifies the bones and teeth and may help maintain healthy blood pressure. It may also help support healthy hormone levels. Calcium carbonate may also function as an antacid and support healthy digestion.

  • Supports bone health
  • Fortifies the teeth
  • May help maintain healthy blood pressure

Serving Size & Timing

The suggested serving size for Calcium Carbonate is about 1250mg, to be taken one or two times per day, depending on the intended effect. Since the FDA recommendation for Calcium intake per day is about 1000mg, and Calcium Carbonate contains about 40% Calcium; this means that a serving of 1250mg contains about 500mg, half of what the FDA recommends for total daily Calcium intake.

The best way to maintain healthy levels of Calcium is to have a Calcium-balanced diet. Since a single serving of any type of dairy generally contains about 300mg of Calcium, someone who has about four servings of dairy on a daily basis need not supplement their diet with anymore.


This form of Calcium Carbonate is considered USP grade and does not contain any fillers. It is made up of about 40% Calcium by weight.


This supplement should be avoided by anyone that is pregnant or nursing. Any side effects from Calcium Carbonate are rare and typically only occur if suggested serving sizes are not adhered to. Side effects include loss of appetite, increased frequency of urination and dry mouth.

Calcium has the potential to bind to many different medications and to reduce the level of acidity in stomach acid or urine. While this would not necessarily neutralize them, it could cause their effectiveness to be diminished significantly. Taking this supplement should be discussed with a health care professional if this is a concern.


Calcium Carbonate should be well dissolved into water or juice. It is best to take Calcium Carbonate with a Vitamin D supplement or with Vitamin D-rich foods or drinks, as this will increase the effectiveness of Calcium absorption. The powder should be stored in an area that is far away from any source of light or heat and should also be kept in a dry environment away from moisture.


There is no guarantee of specific results and results can vary.

I recommend this product

Great service, fast shipping, thanks!

Product is excellent. Product review fields with a character minimum are not.


Used for homemade toothpaste

I bought this to use in making an homemade remineralizing toothpaste that I read from wellness mama's blog. I could see and feel the difference in the cleanliness and whiteness in my teeth. The product is clean and very finely ground just as exactly what I was hoping to get.


helpful in building my bones and decreasing heartburn

So I started taking this supplement because I simply don't get enough calcium in my diet and I want to make sure my body has all the necessary ingredients to maintain strong bones. The great added bonus for me is that I suffer from heartburn somewhat regularly and this I notice if I take a dose of Calcium Carbonante before bed my heartburn immediately goes away and I get a good nights rest without constantly waking up in the middle of the night. I will continue to use this product. Thanks Bulk Supplements.



I receive it .thanks


Calcium Carbonate

I'm super excited about this supplement. I recently started making my own homemade toothpaste. I was extremely happy to see that calcium carbonate is available on this site. It's an ingredient that I need to help strengthen the enamel of our teeth. The order was received promptly and it was packaged well. If you're in the market for high quality supplements, I highly recommend Bulk Supplements.
