Difference Between Calcium and Vitamin


Main Difference

The main difference between calcium and vitamin is that calcium is necessary for tissue growths while calcium is a mineral that is needed for mineralization of bones, teeth, and shells.

What is Calcium?

Calcium is a chemical element having atomic number 20 and symbol Ca. Calcium is a soft gray alkaline earth metal and fifth most abundant element by mass in the Earth’s crust. The ion Ca2+ is also the fifth most abundant dissolved ion in sweater by both morality and mass, after sodium, chloride, magnesium, and sulfate. Calcium is usually produced in the explosions at the end of the life of massive stars. Calcium is very essential for living organisms, in particular in cell physiology, where movement of the calcium ion into and out of the cytoplasm functions as a signal for many cellular processes. It is the most abundant metal by mass present in many animals and used in mineralization of bone, teeth, and shells.


What is Vitamin?

Vitamin is a organic compound and a vital nutrient that an organism requires in a certain amounts. An organic chemical compound is called a vitamin when the organism can’t synthesize the compound in sufficient quantities, and must be obtained through diet; thus, the term vitamin is conditional upon the circumstances and the particular organism. For example, ascorbic acid – one form of vitamin C – is a vitamin for humans, but not for most other animal organism. Supplementation is important for the treatment of certain health problems, but there is little evidence of nutritional benefit when used by otherwise healthy people.

Key Differences

  1. Vitamin, especially vitamin C can support calcium absorption, but too much can have a detrimental effect on calcium stores.
  2. Calcium is a chemical element while vitamin is an organic compound.
  3. Calcium is measured in milligram while vitamin is measured in international unit (IU).
  4. Calcium requirement varies from age to age while vitamin-D requirement from one year to 50 years remain same.
  5. Calcium is necessary for tissue growths while calcium is a mineral that is needed for mineralization of bones, teeth, and shells.
