Calcium Citrate: What It Is and Its Health Benefits

What Is Calcium Citrate?

Calcium citrate is a calcium salt derived from citric acid, commonly used as a dietary supplement to support bone health. Unlike calcium carbonate, which requires stomach acid for absorption, calcium citrate is more easily absorbed, making it an ideal choice for individuals with low stomach acid or digestive issues.

Benefits of Calcium Citrate

1. Supports Bone Health – Calcium is essential for maintaining strong bones and preventing osteoporosis, especially in older adults.
2. Improved Absorption – Calcium citrate is better absorbed on an empty stomach compared to other forms, making it suitable for people taking acid-reducing medications.
3. Helps Prevent Calcium Deficiency – Adequate calcium intake is crucial for muscle function, nerve signaling, and cardiovascular health.
4. May Reduce Kidney Stone Risk – Some studies suggest citrate can help prevent certain types of kidney stones.

Who Should Take Calcium Citrate?

– Older adults at risk of osteoporosis
– Individuals with low stomach acid (e.g., those on antacids)
– Postmenopausal women needing extra bone support
– Vegans or lactose-intolerant individuals with limited dietary calcium

Recommended Dosage

The recommended daily intake varies by age and gender, typically ranging from 1,000 to 1,300 mg per day. Since calcium citrate contains 21% elemental calcium, adjust the dose accordingly.

Potential Side Effects

Excessive calcium intake may lead to constipation, gas, or bloating. Always consult a healthcare provider before starting supplements, especially if taking medications.

Conclusion

Calcium citrate is a highly absorbable form of calcium that supports bone health and overall wellness. If you’re looking for an effective calcium supplement, especially if you have digestive concerns, calcium citrate may be the right choice.
