Calcium Absorption

Most of us only consume half of the calcium that our body needs. In addition, most of us are unaware that there are numerous factors that either inhibit or contribute to our body’s calcium absorption. First, we must understand how the body absorbs calcium.

The parathyroid glands are located in the front of the neck, below the larynx or voice box. They produce a hormone called PTH, which plays an essential role in calcium absorption. The PTH hormone moves calcium into the bloodstream from the bones and signals the kidneys to create calcitriol. Calcitriol (vitamin D3) is formed from vitamin D and it signals the small intestine to absorb calcium.

Even though the body absorbs calcium on its own naturally, there are factors that either contribute to this ability or antagonize it. Facilitators of proper calcium absorption include vitamin D, vitamin K, magnesium, hydrochloric acid, estrogen, small amounts of fat and exercise. Some calcium supplements include extra vitamin D, K or magnesium to aid in our absorption. The contents of our diet can sometimes inhibit proper absorption.

The phosphoric acid in soft drinks interferes with calcium absorption because the more phosphorous we add to our body, the more calcium we need. High fiber diets often contain phytic acid. This acid binds to minerals (calcium included) and forms insoluble salts that are wasted from the body. Other antagonists of calcium absorption include coffee, sugar, salt, alcohol, excessive amounts of fat and oxalic acid. Since the majority of us can’t avoid coffee, soft drinks, sugar and so on, calcium supplementation may be necessary. DrugNatural features several options for calcium supplements.
