Side Effects of Calcium Supplements: What You Should Know

Calcium is essential for strong bones, teeth, and overall health—but too much of a good thing can backfire. Many people take calcium tablets or supplements daily without thinking twice, but are there risks? Let’s take a closer look at the most common calcium supplement side effects, how to avoid them, and safer alternatives for your long-term health.

Common Side Effects of Calcium Supplements

Most people tolerate calcium well when taken at recommended doses. However, taking too much can lead to uncomfortable or even serious side effects, including:

• Digestive issues: constipation, gas, or bloating

• Nausea and loss of appetite

• Increased urination

• Irregular heart rhythm (in rare cases)

• Kidney damage or kidney stones with long-term excessive intake

Research from the National Institutes of Health (NIH) also shows that high calcium intake from supplements—not food sources—may increase the risk of kidney stones.

Side Effects of Taking Calcium Tablets Daily

If you’re consistently taking calcium tablets above the recommended amount, your body may not be able to process the excess. Over time, this can increase the risk of:

• Hypercalcemia (too much calcium in the blood)

• Mineral imbalance (interfering with magnesium and iron absorption)

• Potential links to certain health conditions if overused

Safe Dosage Guidelines

To lower your risk, it’s important to stick to safe daily limits. According to the Institute of Medicine, the tolerable upper intake level (UL) for calcium is:

• 0–6 months: 1,000 mg

• 7–12 months: 1,500 mg

• 1–3 years: 2,500 mg

• 9–18 years: 3,000 mg

• 19–50 years: 2,500 mg

• 51+ years: 2,000 mg

Remember: this includes both supplements and calcium from foods like milk, yogurt, and leafy greens.

How to Take Calcium Supplements Safely

• Don’t exceed the recommended daily allowance unless directed by your doctor.

• Take calcium with food to improve absorption.

• Combine calcium with vitamin D and magnesium, which support proper bone health and balance.

• Track your intake for a few days to ensure you’re not overdoing it.
