Organic calcium and inorganic calcium refer to different types of calcium compounds.
Inorganic calcium is calcium that is not combined with carbon. It is commonly found in rocks, minerals, and shells, and is often used as a supplement in food and medicine. Examples of inorganic calcium compounds include calcium carbonate (found in rocks, shells, and antacids), calcium phosphate (found in bones and teeth), and calcium chloride (used as a food preservative and de-icer).
Organic calcium, on the other hand, is calcium that is combined with carbon and other organic molecules. It is found in a variety of foods, particularly in dairy products and leafy green vegetables. Organic calcium compounds include calcium citrate (found in citrus fruits), calcium lactate (found in dairy products), and calcium gluconate (used as a dietary supplement).
The main difference between organic and inorganic calcium is the way in which they are combined with other molecules. Organic calcium compounds are typically more easily absorbed and utilized by the body than inorganic calcium compounds. This is because the organic compounds are more readily broken down and absorbed by the digestive system, while inorganic compounds often require additional processing before they can be utilized.
Overall, both organic and inorganic calcium are important sources of this essential mineral for the body. While organic calcium is generally considered to be more easily absorbed and utilized, inorganic calcium can still be an important supplement for those who have difficulty obtaining sufficient calcium through diet alone.
