Review: Es un complemento que el veterinario mandó para mi perro, o sea el uso no solo es para humanos; debo comentar que es parte de la dieta de mi mascota y sentimos real mejoría en mi mascota.
Review: 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.

## Questions & Answers

**Q: Are all calcium carbonates the same? I would like to use some to make my own chalk paint. Does one brand work better than others?**
A: I purchased the 5 Pound package of Calcium Carbonate by Raw Supply, for $10.47. It will make a lot of chalk paint! Plus, I figure I'll use some of it on the garden too, in the compost pile. I won't use it for health care though, since it isn't labeled "pure" (or w/USP symbol on it), so it could contain traces of lead or other toxic metals. Fine for chalk paint though!

**Q: can I use this for making toothpaste?**
A: Yes it will make an excellent toothpaste , here is the formula: for every table spoon of calcium carbonate one table spoon coconut oil one drop oil of peppermint , one drop of oil of spearmint, one tea spoon xylitol or organic honey and add a little water to make it gel like.Not only this formula clean your teeth the best but will naturally disinfect your mouth from bacterium buildup.

**Q: How is this vegetarian? Does it contain bonemeal?**
A: The bottle reads that it is a Vegetarian/Vegan product.  No other ingredients added.There is no sugar, salt, starch, yeast, wheat gluten, corn, soy, milk, egg, shellfish or preservatives.Hope this helps.  I purchased this to make chalk paint because it dissolves so well.

**Q: Does this contain lead?**
A: It contains elemental calcium from calcium carbonate and then it says "Other ingredients: None" so I assume no lead. It also says non-GMO.
