Calcium is a mineral, which is a solid inorganic substance that the body needs to function. It is the most abundant mineral found in the human body and is primarily stored in the bones and teeth.
It is used to support the strength and density of the skeletal system. This helps prevent bones from becoming brittle or thin. It also plays a role in how muscles contract and how nerves send signals throughout the body.
While both are common supplements, they serve entirely different roles in the body.
| Feature | Calcium | Vitamin C |
|---|---|---|
| Type | Mineral (inorganic) | Vitamin (organic) |
| Primary Role | Bone and tooth structure | Immune support and skin health |
| Source | Rocks, shells, or dairy | Fruits and vegetables |
Commercial calcium supplements are produced by extracting the mineral from natural sources like limestone or seashells. These raw materials are processed using chemicals to create a concentrated powder, such as calcium carbonate. This powder is then measured and pressed into hard tablets or filled into gelatin capsules for sale.
This supplement is generally mid-range in price. This is because while the raw mineral sources are plentiful and cheap to find, the industrial processing required to make the mineral pure and easy for the body to absorb adds to the production cost.
