Minerals

Calcium

Calcium supports strong bones, powerful muscle contractions, and nerve function. Maintaining optimal levels is essential for men who lead an active lifestyle.

What It Measures

This test measures the total calcium level in your blood. It reflects both the calcium bound to proteins and the free (ionised) calcium available for metabolic functions.

Why It Matters

Calcium balance is critical for bone health, heart function, and muscle contraction. Abnormal levels may be associated with bone disorders, parathyroid conditions, or kidney problems. Consult your healthcare provider for personalised advice.

When to Test

Testing may be recommended as part of routine health screening, or if you have symptoms such as bone pain, muscle cramps, fatigue, or a history of kidney stones.

Symptoms

Low Levels

Symptoms of low calcium may include muscle cramps or spasms, numbness and tingling in fingers, fatigue, and in severe cases, heart rhythm abnormalities.

High Levels

Symptoms of high calcium may include excessive thirst, frequent urination, abdominal pain, nausea, bone pain, and confusion. Persistent high calcium warrants medical evaluation.

Lifestyle Tips

Include calcium-rich foods such as dairy products, leafy greens, almonds, and fortified foods. Ensure adequate vitamin D intake to support calcium absorption. Regular weight-bearing exercise also supports bone health.

Frequently Asked Questions
