Calcium Carbonate
Calcium Carbonate is a chemical compound having the chemical formula CaCO3. It is a white and insoluble powder-like substance that occurs naturally in minerals, marble, chalk, limestone, shells, calcite, pearl, and other related compounds. Medicinally, we use it as an antacid or a calcium supplement. It can also be used as cosmetics fillers.

Dr. Stone: What the Anime Gets Incorrect About Gunpowder
After all, as Senku says, gunpowder is simply made from sulfur, charcoal and potassium carbonate. The keen reader may have already picked up on the major error, which can be seen in Episodes 2-4 of the anime and in Chapter 4 of the manga. It is not calcium carbonate that is used in gunpowder, but rather potassium carbonate.

Calcium Carbonate vs Calcium Citrate: The Key Differences
Calcium carbonate has more elemental calcium than calcium citrate (40% in carbonate, 21% in citrate). So you may have to take more calcium citrate tablets to get the desired amount of calcium. Thankfully, you don't have to do any calculations. Your supplement's label should tell you exactly how much elemental calcium is in a serving.
