COMPARING ORGANIC CALCIUM AND INORGANIC CALCIUM, WHICH IS BETTER?

COMPARING ORGANIC CALCIUM AND INORGANIC CALCIUM, WHICH IS BETTER?

Organic and inorganic calcium are two forms of calcium. However, not everyone can distinguish between these two forms of calcium and the benefits they bring to the body. In this article, DDA will help you answer the question: "Organic and inorganic calcium, which form of calcium is better?"

What is organic calcium?

Organic calcium is calcium compounds combined with organic radicals, usually derived from plants and animals, safe for human health. The advantage of organic calcium is that in addition to calcium ions, there are other organic substances such as proteins, amino acids and other substances. These organic substances help enhance and support the body's absorption of calcium and minerals.

What is inorganic calcium?

Inorganic calcium is made up of calcium and inorganic compounds. Inorganic calcium can be produced from chemical reactions or taken from natural organisms such as oyster shells, clam shells, snail shells, etc. In fact, inorganic calcium exists in compound forms such as calcium carbonate, calcium phosphate, calcium chloride, etc.

Distinguishing between organic and inorganic calcium

To distinguish these two types of calcium, we can rely on characteristics such as solubility, calcium ions and ease of drinking.

Characteristics

Inorganic Calcium

Organic Calcium

Solubility

Inorganic calcium is poorly soluble, hard to absorb in the body, easily accumulates and causes vascular calcification, kidney stones, cardiovascular issues, and even stroke. It also causes internal heat, constipation, and affects the metabolic processes of both mother and baby.

Organic calcium dissolves quickly, is well absorbed, and causes little to no accumulation or calcification. It does not cause internal heat or constipation and does not affect the metabolic processes of mother and baby.

Additional nutrients

Inorganic calcium contains only calcium ions and does not include other minerals.

Organic calcium contains calcium ions along with other nutrients such as proteins, amino acids, etc.

Ease of consumption

Inorganic calcium often has an unpleasant taste and is difficult to drink.

Organic calcium has a mild aroma and is easy to drink.


Why is organic calcium better than inorganic calcium?

Calcium is absorbed in the intestine by passive transport mechanism, so to absorb calcium, it must be in soluble form or associated with organic compounds to be absorbed. Therefore, organic calcium has higher bioavailability than inorganic calcium. In addition, inorganic calcium when absorbed into the body can cause calcium deposits in the blood vessel wall, kidney, long-term kidney stones. For pregnant women, it can cause calcification of the placenta, unable to provide food for the baby.

Supplement calcium from many sources

Who should use organic calcium?

Calcium is an important mineral for the body, so people of all ages can use organic calcium. However, some people should prioritize calcium supplements such as:

People with Crohn's disease or enteritis: These are diseases that reduce the body's ability to absorb calcium, leading to calcium deficiency. Organic calcium can help improve the body's absorption and does not cause irritation.

Vegetarians: Vegetarians are often calcium deficient due to inadequate nutrition in their diet. Organic calcium is a natural source of calcium and is suitable for vegetarians.

Premenopausal women: During premenopause, estrogen levels decrease, making it difficult for the body to retain calcium. In addition, calcium also decreases with age. Supplementing organic calcium can help prevent osteoporosis and cardiovascular complications.

Pregnant women: A study has shown that pregnant women who supplement at least 1000mg of calcium per day can reduce the risk of premature birth.
