Calcium is essential for maintaining strong bones and teeth. Regular intake of calcium citrate can help prevent osteoporosis and support overall skeletal health, particularly in older adults and postmenopausal women.
4. Additional Health Benefits
Beyond bone health, calcium citrate may play a role in cardiovascular health by helping to maintain normal blood pressure levels. It can also aid in muscle function and nerve transmission, contributing to overall bodily functions.
Conclusion
The calcium citrate USP monograph serves as a fundamental guide for ensuring the quality, safety, and efficacy of calcium citrate supplements. Understanding the monograph’s components can help consumers make informed choices when selecting dietary supplements. With its enhanced absorption and versatility, calcium citrate is an excellent option for those looking to improve their calcium intake and support their overall health. Always consult with a healthcare provider before starting any new supplement regimen to ensure it meets your individual health needs.
