Calcium Carbonate (Caltrate 600) Uses, Side Effects & Formula

What is calcium carbonate? Why is it used?

Most people know that calcium is needed for strong bones, but it's also needed to help blood vessels and muscles contract and expand, to send messages through the nervous system, and to secrete hormones and enzymes. This is the most abundant mineral in your body and makes up 1%-2% of adult human body weight. Over 99% of it is stored in bones and teeth with the rest stored in blood, muscle, and other tissues.

Bone is a living tissue that constantly breaks down and builds back up. Up until around the age of 30, consuming an adequate amount of calcium with enough physical activity ensures that your body builds more bone than it breaks down. The majority of adult bone mass is acquired by age 18 in girls and 20 in boys. After that, breakdown typically exceeds the amount of bone being built. For this reason, it's essential to maximize bone stores when it's still possible. The amount that you lose after age 30 will be impacted by genetics, ethnicity, physical activity level, sex hormone levels, diet, and gender. You can replace what you lose with the foods you eat and your activity level, but you can't increase how much you store. When bone mass drops and there is a deterioration of bone tissue, osteoporosis can occur. Osteoporosis causes bones to be susceptible to fractures. Depending on the severity of the damage, bones can break from a minor fall, or in severe cases, from sneezing.

The usual recommended dose of calcium replacement is 1 to 1.2 g given

4 tablets per 24 hours not to exceed 7 g a day.

Which drugs or supplements interact with calcium carbonate?

: Calcium can make it difficult for
the body to absorb
certain medications. Calcium products bind to quinolone (for example,

ciprofloxacin)
and tetracycline (for
example, Sumycin) antibiotics in the intestine and can prevent
their absorption into the body. To prevent this interaction, doses of quinolone
and tetracycline antibiotics should be separated by three or more hours from
doses of calcium.

Calcium carbonate-containing products reduce acidity in the stomach. The
reduction of acid decreases the absorption of iron from the intestine.
Therefore, doses of calcium and iron should be separated by a several hours.

Calcium products also bind to sodium polystyrene sulfonate (Kayexalate, a drug used to treat high levels of
potassium) in the intestine and, therefore, may interfere with the action of Kayexalate. Doses of Kayexalate and calcium products should be separated by
several hours.
