Review: best addition to the toothpaste I have been making for ... - I don't have any other calcium carbonate powder to compare it with since this is my first go at it, but this is the newest, best addition to the toothpaste I have been making for years. This powder is fine and fluffy with no noticeable grit, and also dissolved easily in water when I added it as a supplement for my 94-year old grandma. It has no taste at all, so it's also great in smoothies, hot cereal, or however you want to use it. As to the toothpaste application: I have seen lots of mention of wellnessmama.com's recipe, which is good, but in my opinion this (recipe below) is even more beneficial because of the extra whitening , anti-inflammatory, and anti-microbial action of turmeric (yes, turmeric WHITENS teeth!) which solved a years-long problem I used to have of bleeding gums every time I brushed. Also, bentonite clay actively removes toxins, like whatever leeches from the old-school silver fillings I still have. Finally, the combination of the magnesium, calcium, and silica from the diatomaceous earth** makes the minerals maximally absorbable when brushing. At the time I started making & using this toothpaste I was starting to feel soreness in 2 of my back molars as well as temperature sensitivity and was getting worried about a huge impending dental bill. It only took a couple of months before the problems disappeared. Yes, you can heal your teeth, no matter what they tell you. Besides, ALL of these ingredients have multiple uses in my house and are extremely beneficial in multiple ways. Here's what I did (measurements are approximate, adjust for texture): **with diatomaceous earth as a mild abrasive, you really don't need baking soda, but if you want to take advantage of its alkalizing and antibacterial power you can add a bit less of it in proportion to the other powders. I personally don't like the taste so I started leaving it out. DO NOT LET THIS COME IN CONTACT WITH METAL OR USE METAL UTENSILS AS IT WILL DE-ACTIVATE THE BENTONITE CLAY. 1) Mix equal parts (around a teaspoon) calcium powder; food grade diatomaceous earth; organic turmeric powder; and a couple pinches of cinnamon and/or ginger powder together. 2) Moisten 2 teaspoons bentonite clay (calcium bentonite clay is better for this, but either type will work) by slowly adding to about a tablespoon of distilled water while stirring. Let it sit to absorb the water and mix til you get the silky paste you would normally use for a face mask. 3) Gradually add your powders into the clay while stirring to blend. 4) Pour about 2 teaspoons magnesium oil over the mix and blend well. 5) Add around 10 drops cinnamon essential oil. Not only is it anti-bacterial and freshening but it tastes good. (Don't overdo this as too much will cause a burning sensation.) 6) Last, add around 2 teaspoons organic virgin coconut oil in liquid form and however much beyond that to get the texture you are going for. * I don't personally sweeten this blend, but if you really want to you can add 1/4 teaspoon of Xylitol powder. A couple of notes: -I have found that popsicle sticks are the best thing to mix this stuff with as it lets me smooth out any chunks, and it tends to gunk up on most plastic silverware because of the way it is shaped. -Between all of these ingredients, you have a nice, anti-microbial mouth-freshening toothpaste which detoxifies your whole mouth as well as provides minerals to your tooth in their most available form. I know I will NEVER buy commercial toothpaste again. Try it and comment on how it works for you! -In combination with the ancient Ayurvedic practice of oil-pulling, while using this toothpaste mix I have not only had no dental issues but also haven't gotten so much as a common cold in almost five years. It truly is the cheapest dental insurance plan you can buy!!

I add it to my home made dog food. I consulted Grok on ingredients and it said all were good but the food was lacking in CaCO3, so I bought this food grade from desertcart. It's a nice, smooth powder and It should last me a long time. It comes very well packaged. ## Features - High Quality Food Grade Calcium Carbonate White Powder, Made from Limestone - Safe for Human Consumption & For use with Foods - May be used as a calcium dietary supplement - Use to make Homemade Toothpastes, Chalks, Fillers, Extenders, Colorants, etc - Double Bagged Packaging ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B00959XKGI | | Best Sellers Rank | #68,403 in Health & Household ( See Top 100 in Health & Household ) #403 in Calcium Mineral Supplements | | Brand | Duda Energy | | Brand Name | Duda Energy | | Customer Reviews | 4.7 out of 5 stars 826 Reviews | | Flavor | Unflavored | | Included Components | Calcium Carbonate | | Item Form | Powder | | Item Weight | 1 Pounds | | Manufacturer | Duda Energy | | Material Type Free | GMO Free | | Number of Items | 1 | | Primary Supplement Type | Calcium | | UPC | 840194114271 | | Unit Count | 1 Count | ## Product Details - **Brand:** Duda Energy - **Item Form:** Powder - **Primary Supplement Type:** Calcium - **Unit Count:** 1 Count - **Flavor:** Unflavored ## Images ![FGcc1f Food Grade 97+% Calcium Carbonate from Ground Limestone, 1 lb. - Image 1](https://m.media-amazon.com/images/I/71rN7l2zP5L.jpg) ## Customer Reviews ### ⭐⭐⭐⭐⭐ best addition to the toothpaste I have been making for ... *by I***G on January 26, 2016* I don't have any other calcium carbonate powder to compare it with since this is my first go at it, but this is the newest, best addition to the toothpaste I have been making for years.

I add it to my home made dog food. I consulted Grok on ingredients and it said all were good but the food was lacking in CaCO3, so I bought this food grade from Amazon. It's a nice, smooth powder and It should last me a long time. It comes very well packaged. ### ⭐⭐⭐⭐⭐ It helps alge and fish health *by P***S on August 13, 2025* I have 1/2 acre pond and at first I used only 10lbs. I noticed my alge wasn't as bad so I ordered another 10lbs. Then I noticed my alge was 90% better, so I've ordered another 10 lbs to totally clear up my pond. I may note my catfish were dying due to lack of calcium in my pond. I can't tell yet if they are ok yet, but they are more lively than before I added this product. ## Frequently Bought Together - Duda Energy FGcc1f Food Grade 97+% Calcium Carbonate from Ground Limestone, 1 lb. - Sodium Alginate 100% Food Grade | Natural Thickening Powder & Gelling Agent for Cooking (16 Oz) - Herbaila Sodium Bicarbonate 2lb, Baking Soda for Cleaning and Baking, Aluminum Free Baking Soda for Pool, Pure Baking Soda Powder, Bulk Baking Soda Food Grade, Sodium Bicarbonate Powder --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.us/products/4648207-fgcc1f-food-grade-97-calcium-carbonate-from-ground-limestone-1](https://www.desertcart.us/products/4648207-fgcc1f-food-grade-97-calcium-carbonate-from-ground-limestone-1) --- *Product available on Desertcart United States of America* *Store origin: US* *Last updated: 2026-05-19*
