Can Calcium Tablets Cause Constipation?
Calcium supplements are widely used for various health benefits, particularly for bone health. However, there is a common concern about whether these supplements can cause constipation. This article synthesizes findings from multiple research studies to address this question.
Calcium Supplementation and Constipation: Mixed Evidence
No Significant Impact on Healthy Individuals
A study focusing on healthy women found that calcium supplementation, whether from calcium carbonate or calcium phosphate, did not significantly affect stool frequency or form. The participants reported similar stool frequencies and types across different periods, including baseline, supplementation, and washout phases. This suggests that calcium supplementation at a dose of 500 mg/day does not contribute to constipation in healthy individuals .
Potential Gastrointestinal Side Effects
Contrary to the findings in healthy women, another study reviewed adverse events from calcium supplementation and found that gastrointestinal issues, including constipation, were more common in participants receiving calcium supplements compared to those on a placebo. The study reported a relative risk increase for gastrointestinal adverse events, including constipation, bloating, and abdominal pain, among those taking calcium supplements .
Calcium Polycarbophil and Constipation Relief
Interestingly, calcium polycarbophil, a specific form of calcium supplement, has been shown to alleviate constipation, particularly in patients with irritable bowel syndrome (IBS). Multiple studies have demonstrated that calcium polycarbophil significantly improves stool consistency and ease of passage, making it an effective treatment for constipation-predominant IBS 3467. These findings suggest that not all calcium supplements have the same effect on bowel movements, and the form of calcium used can make a significant difference.
Conclusion
The relationship between calcium supplementation and constipation is complex and appears to depend on the form of calcium and the population being studied. While general calcium supplements like calcium carbonate may cause gastrointestinal issues, including constipation, in some individuals, specific forms like calcium polycarbophil can actually help alleviate constipation, especially in those with IBS. Therefore, individuals concerned about constipation should consider the type of calcium supplement they are using and consult healthcare providers for personalized advice.
