A quick look into how vitamin D deficiency may unexpectedly influence iron buildup in the body.
VITAMIN D & IRON OVERLOAD:
THE HIDDEN CONNECTION
HOW IRON METABOLISM WORKS
Iron is absorbed in the small intestine and stored mainly as ferritin. Hormones like hepcidin regulate how much iron enters and circulates in the body.
WHAT IS IRON OVERLOAD?
Iron overload occurs when excess iron accumulates in organs like the liver, heart, and pancreas. It may be hereditary or caused by transfusions, supplements, or chronic disease.
VITAMIN D’S ROLE IN IRON REGULATION
Vitamin D influences genes involved in iron absorption and storage. It also impacts hepcidin, the hormone that tells the body when to block or allow iron entry.e.
CAN LOW VITAMIN D CAUSE IRON BUILDUP?
Low vitamin D is linked to higher iron levels. It may reduce hepcidin control, allowing excess iron to build up.
Low vitamin D can lower red blood cell production while still allowing excess iron to build up, creating a complex imbalance.
SYMPTOMS & DIAGNOSTIC TESTING
Both cause fatigue. Low vitamin D leads to bone and muscle pain, while iron overload causes joint pain, stomach issues, and skin darkening.
TREATMENT & PREVENTION STRATEGIES
Treatment includes vitamin D supplementation, phlebotomy for iron overload, and dietary adjustments. Regular monitoring helps prevent nutrient imbalance.
WHY THIS CONNECTION MATTERS
Vitamin D and iron interact through shared pathways. Understanding this link helps clinicians diagnose, treat, and prevent nutrient-related disorders more effectively.
