Top Calcium Supplements for Optimal Bone Health

Calcium plays a crucial role in maintaining strong bones and teeth, accounting for 99% of calcium in the body. The remaining 1% is vital for functions like blood clotting, muscle contractions, nerve signaling, and hormone release. On average, calcium constitutes about 2.3% of our total body weight. Adults are recommended to consume between 1000 and 1200 mg of calcium daily. Deficiency can arise from low intake or insufficient absorption due to deficiencies in vitamin D, magnesium, or phosphorus.

Calcium deficiency comes in two forms:

• Dietary deficiency: Results from inadequate calcium intake, leading to weakened bones and osteoporosis.
• Hypocalcemia: Low calcium levels in blood, often caused by medication side effects.

Symptoms include muscle cramps, dry skin, brittle nails, weak bones, fractures, and delayed puberty. If untreated, calcium deficiency can lead to osteoporosis, heart issues, hypertension, or even cancer. Early detection and supplementation are essential for overall health.

To address calcium deficiency, supplements are available mainly as calcium carbonate and calcium citrate. Effective supplements should include vitamin D to boost absorption and be in forms easily processed by the body. Some popular brands include:
