Calcium and Chronic Kidney Disease: What You Need to Know for Kidney & Heart Health
Managing calcium levels in chronic kidney disease (CKD) is essential for protecting both kidney and cardiovascular health. Imbalances in calcium can lead to serious complications like vascular calcification, kidney stones, and bone mineral disorders. In this video, Lindsey Zirker unpacks the complex relationship between calcium, vitamin K, PTH, and kidney function and why getting this balance right is critical in CKD management.
🎥 Inside this video, you’ll learn:
- Why calcium regulation is vital in CKD and how imbalances impact the body
- Early signs and symptoms of calcium deficiency or excess in kidney patients
- The role of vitamin K in directing calcium to the bones not the arteries
- When and how to use calcium supplements safely to avoid hypercalcemia
- How parathyroid hormone (PTH) and vitamin D affect calcium metabolism in CKD
- The connection between calcium, oxalates, and kidney stone formation
- Practical tips for choosing the right calcium supplements for kidney health
This video is a must-watch for anyone navigating CKD, offering research-backed insights and practical strategies for maintaining safe calcium levels and reducing long-term complications.
👉 Watch now to learn how calcium management can support both kidney and heart health in CKD.
