What is Calcium Carbonate?
Calcium carbonate (chemical formula CaCO3) occurs naturally in rocks like limestone, most often as calcite
and aragonite minerals. Unsurprisingly, the word calcium comes from the Latin word for lime, calx.
It is the primary component of shellfish skeletons, pearls, and eggshells. Calcium is an essential mineral
and electrolyte that the body needs to maintain optimum circulatory, digestive, and muscular health, and
it’s crucial for bone formation. It plays a role in muscle contraction, blood clotting, hormone secretion,
and nerve impulse transmission.
Calcium Deficiency Symptoms
Nearly half of the world's population is also at risk due to low dietary intake of calcium. Calcium
deficiencies are most commonly the result of impaired thyroid function or a vitamin D or magnesium
deficiency. Certain groups are more at risk of developing a calcium deficiency. These include individuals
with lactose intolerance or milk allergies, vegans, other individuals avoiding dairy products, and
menopausal or postmenopausal women. Estrogen levels rapidly decline at the onset of menopause and continue
to do so for up to five years. Less estrogen reduces the rate of bone formation and increases the rate of
bone absorption, resulting in a rapid loss of bone mass.
Symptoms of calcium deficiency include:
- Muscle spasms
- Tingling hands and feet
- Mouth numbness
- More frequent falls
- Weak or brittle bones
Potential Calcium Benefits
Calcium for Bones and Teeth
Calcium and Vitamin D
The body needs vitamin D
calcium. Spending a lot of time indoors or being over 65 increases the risk of developing a vitamin D
deficiency, which can trigger a calcium deficiency.
Calcium is essential for forming and maintaining strong bones and teeth. Research also shows that eating a
calcium-rich diet directly correlates to superior bone health. The FDA recognizes the importance of calcium
for the normal development and maintenance of bone health. Adequate calcium intake is particularly important
for older adults to inhibit loss of bone mass, as sustaining bone mineral density helps maintain bone
strength. When paired with vitamin D, calcium supplements may reduce the likelihood of bone fractures in
Calcium Carbonate Antacid Effects
Calcium carbonate is a common ingredient in antacids, as it helps relieve upset stomach, heartburn, and acid
indigestion. It protects the mucus membrane lining the stomach by neutralizing stomach acid. Less stomach
acid means less erosion and acid reflux.
Calcium Carbonate Powder and Heart Health
Calcium supplements may enhance heart health due to how calcium interacts with fats and vascular cells.
Research shows that calcium appears to diminish how much dairy fats affect blood lipid levels. One study
found that calcium-fortified milk led to a reduction in lipid (fat) absorption by improving the body’s
natural fat excretion processes. The research noted dramatic increases in excretion, with a 139% increase in
total fat excretion and a 195% increase in fatty acid excretion. Other studies show that calcium may reduce
vascular cell pressure due to its antihypertensive properties.
Calcium and Kidney Stones
is a better option for
individuals at risk of developing kidney stones. The inclusion of citrate inhibits kidney stone formation
without impeding calcium absorption
Potential Calcium Side Effects
Individuals may experience mild side effects while taking calcium carbonate powder. These are usually
gastrointestinal in nature, such as bloating, gassiness, or constipation. Calcium carbonate may increase the
risk of kidney stones in individuals predisposed to developing them. Taking calcium carbonate powder with
food reduces the risk of developing kidney stones and improves calcium absorption.
