This calcium mixes up with water easily for drinking, although it does leave residue in the glass you'll need to clean out. It also works very well in homemade tooth powder. Making our own tooth powder has substantially improved my daughter's tooth sensitivity. This is a very pure calcium, so we feel safe using it. We also don't react to it, as we do the calcium citrate, often made from corn. Homemade tooth powder gives a wonderful polished-feeling clean and helps a ton with sensitive teeth. If you want to try it and don't have your own recipe, this recipe works great for our family: Tooth Powder Ingredients ½ cup bentonite clay - Pure Clay - Premium Calcium Bentonite Clay Food Grade (Montmorillonite) Powder - Laboratory Tested for Purity - Internal Detox and Cleanse - Mask, Body Wrap and Bath ½ cup calcium Carbonate Powder (not Citrate) - NOW Calcium Carbonate Powder, 12-Ounces 2 tbsp baking soda 4 tbsp Xylitol - Zveet Birch Xylitol Sweetener 5lb (Made in USA) 20 drops of peppermint essential oil or to taste Put all ingredients in a jar and shake well to mix. Ingredients – LARGE BATCH – Makes a 2-quart jar Weights are approximate. Adjust as needed. 16 oz bentonite clay - Pure Clay - Premium Calcium Bentonite Clay Food Grade (Montmorillonite) Powder - Laboratory Tested for Purity - Internal Detox and Cleanse - Mask, Body Wrap and Bath 16 oz calcium Carbonate Powder (not Citrate) - NOW Calcium Carbonate Powder, 12-Ounces 4 oz baking soda 12 oz Xylitol - Zveet Birch Xylitol Sweetener 5lb (Made in USA) 1 teaspoon peppermint essential oil or to taste Put all ingredients except peppermint oil in a bowl and mix well under a vent-a-hood because the clay will give off a lot of powder dust into the air. Sprinkle around the peppermint oil and mix well again. Put in a 2-quart jar. Recipe adapted from Wellness Mama.

Decided to go this route due to not being satisfied with some of the disgusting tasting name-brand antacid tablets. In fact, look at the ingredients of some tablets and you'll find Carmine: a food coloring made from gound up bugs. No, I am not joking! Search for yourself. Anyway, the active ingredient in antacid tablets is Calcium Carbonate so I had the idea to check if it was possible to simply buy pure Calcium Carbonate powder. That way there'd be no additives such as Carmine or sugar or salt, etc. And, therefore, I figured it would be tasteless, which is what I wanted. And that's how I found and bought this product. It is indeed tasteless and it works well as an antacid. In fact, it works better than the tablets in cases where I wake up due to some acid reflux. This fine powder does a better job of neutralizing the acid in my throat than chewables ever did. Trying to swallow the powder dry can be difficult because it is so dry. What I do is keep about a teaspoon of the powder in a small container (which will hold a few ounces of water) with sealable lid. So, when I need it, I just remove the lid, add some water, put the lid back on, shake vigorously, then drink. That way it flows over any acid in my throat (which stops the burning) on its way down to my stomach where it relieves the acid indigestion there. Job done and no unpleasant lingering taste.

Found recipe to make your own chalk paint from acrylic paint. By adding the recommended amount of calcium carbonate powder, I found it to be quite acceptable.

I bought this to use in homemade tooth powder. I wasn't expecting it to do anything exciting, just to function as the remineralizing portion of my tooth powder, and it's great for that purpose. I've tweaked my tooth powder recipe, because the standard recipes weren't quite cutting it for me. I based my recipe off the one from the web site nourishing joy, but I found that there wasn't enough activated charcoal to counteract the tooth stains from my daily coffee, so I upped the ratio of charcoal. Plus, my mouth still didn't quite feel clean after brushing, so I added frankincense oil, which has natural antibacterial properties and makes my mouth and teeth feel super clean. So here's my recipe: 4 tbsp bentonite clay (best to get a brand that's meant for internal use since it's going it your mouth) 4 tbsp calcium carbonate powder (Now brand works great) 1 tsp baking soda 1 tbsp fine sea salt or Himalayan pink salt 4 tbsp activated charcoal powder enough frankincense oil to make the mixture slightly moist but not clumpy Mix everything together, and keep it in an airtight container. I wet my toothbrush very slightly and dip it into the tooth powder and brush with the amount that sticks to the toothbrush. I've found that this mixture works amazingly. It keeps my teeth as white as any whitening toothpaste I've ever used, if not slightly whiter. My teeth haven't been accumulating tartar at all in the 5 months I've been using this. And best of all, my gums, which had been slowly receding for the last 15 years or so, haven't receded one bit since I've been using this. I decided to switch to tooth powder when I learned that glycerin can be irritating to mouth tissue. I wondered if eliminating it would stop my gums from receding, and it's worked. Even the popular brands of natural toothpaste contain glycerin. So, tooth powder has been working much better for me than any toothpaste I've ever tried. Now's calcium carbonate has been a great addition to the tooth powder. I expect this bottle to last me years.
