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.
Vitamin, especially vitamin C can support calcium absorption, but too much can have a detrimental effect on calcium stores.
Calcium requirement varies from age to age while vitamin-D requirement from one year to 50 years remain same.
Calcium is a chemical element while vitamin is an organic compound.
Calcium is measured in milligram while vitamin is measured in international unit (IU).
Calcium is necessary for tissue growths while calcium is a mineral that is needed for mineralization of bones, teeth, and shells.
A silvery, moderately hard alkaline-earth metal that constitutes approximately 3.6 percent of the earth's crust and is a basic component of most animals and plants. It occurs naturally in limestone, gypsum, and fluorite, and its compounds are used to make plaster, quicklime, Portland cement, and metallurgic and electronic materials. Atomic number 20; atomic weight 40.08; melting point 842°C; boiling point 1,484°C; specific gravity 1.54; valence 2. See Periodic Table.
Any of various fat-soluble or water-soluble organic substances that are essential in minute amounts for normal growth and activity of living organisms. They are synthesized by bacteria and plants and are obtained by animals chiefly in their diet.
The chemical element (Symbol Ca), with an atomic number 20. It is a soft, silvery-white alkaline earth metal which occurs naturally as carbonate in limestone and as silicate in many rocks.
A preparation containing one or more vitamins, often taken as a dietary supplement.
(countable) An atom of this element.
Any of a specific group of organic compounds essential in small quantities for healthy human growth, metabolism, development, and body function; found in minute amounts in plant and animal foods or sometimes produced synthetically; deficiencies of specific vitamins produce specific disorders.
A food rich in vitamins
An elementary substance; a metal which combined with oxygen forms lime. It is of a pale yellow color, tenacious, and malleable. It is a member of the alkaline earth group of elements. Atomic weight 40. Symbol Ca.
Any of several organic chemical substances not synthesized by an animal and required in small quantities for normal metabolism, present in and obtained from the natural foods eaten by the animal. Human vitamins are also produced synthetically, and taken in pure form or in mixtures, as dietary supplements. Deficiencies of specific vitamins lead to certain specific disorders, such as scurvy, caused by an insufficiency of vitamin C (ascorbic acid).
A white metallic element that burns with a brilliant light; the fifth most abundant element in the earth's crust; an important component of most plants and animals
Any of a group of organic substances essential in small quantities to normal metabolism
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.
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.
