Calcium plays a vital role in maintaining strong bones and teeth, constituting about 99% of the calcium in our body. The remaining 1% supports functions like muscle contraction, nerve signaling, blood clotting, and enzyme activity. An adult should aim for 1000 to 1200 mg of calcium daily. Deficiency may stem from poor intake or absorption issues related to vitamin D, magnesium, or phosphorus deficiencies.
Calcium deficiency can be categorized as:
Dietary calcium shortage: Results from inadequate dietary intake, causing bone depletion and osteoporosis.
Hypocalcemia: Low blood calcium levels, often due to medication side effects.
Symptoms include muscle cramps, brittle nails, weak bones, fractures, dry skin, and delayed puberty. Prolonged deficiency can lead to osteoporosis, heart issues, hypertension, and possibly cancer. Therefore, early detection and treatment are crucial for overall health.
Calcium supplements help address deficiencies and come mainly as calcium carbonate or calcium citrate. The inclusion of vitamin D improves absorption. Here are some popular options:
