sure is cheaper! I cannot believe the cost of simple antacids these days. I lived with reflux for so many years that I did permanent damage to my esophagus, so I am now on prescriptions. I would be very willing to try this if I was still eating 10 or more Tums a day. But I am grateful that I don't have to these days.

Thanks for the info.

Might do some googling just to find out.

I just hate to throw anything away!

But you are right...calcium is so important for us, it is a shame to have the eggshells go to waste. There must be ways that they can be used to our benefit. Post if you find other uses.

7. Use them to start seedlings. If homemade paper pots aren’t your style, give some of your smaller seedlings a start in rinsed-out shells.

I probably like this idea so much because I use the cardboard cartons as seedling starters already and they are a perfect size. The cardboard doesn't have to be removed when the plants are repotted or planted, since they decompose, and the eggs could be crushed around the dirt before planting and also left with the plant. Cool.

I also liked this, since it is a great idea and you can still use the shells for another use when you are done.

11. Blade Sharpening: Keep them in the freezer and use to clean and sharpen blender blades by adding water. Then pour the mixture into your compost bin.

build up bones if you powder it and ingest it. Web MD and a couple of other sources say calcium carbonate is the form in supplements.

I'm going to try it. I always worry that you pay money for vitamins, and they don't contain anything you think they contain.

Doesn't take much

"Homemade Eggshell Toothpaste

¼ c. Egg Shells or Calcium Magnesium Tablets (Ground up)
1-3 Tbs Coconut Oil
1 Tbs. or less Baking Soda
½ -1tsp. Castile Soap (Optional but I find that it adds some smoothness. I use Dr Bronners Castile Soap. See note above.)
10 Drops Peppermint Essential Oil (please see above note on essential oils.)

1. If using egg shells, give them a quick rinse and bake in the oven at 400 F for 15-20 minutes.
2. Grind up the shells or tablets until powdery fine. I use my coffee grinder for the shells and my food processor for the tablets.
3. Mix the ingredients in a small bowl, adding coconut oil until it is the smooth consistency that you like. * I find that it takes more with the calcium magnesium pills than the eggshells.
4. Store in a small jar and use a small spoon to scoop it on your tooth brush.
5. You can add different essential oils that are said to promote tooth health such as fennel, clove, rosemary, oregano, (to name a few)."
