9 Vitamins & Supplements That DESTROY Your Liver & Kidneys

 

3. Iron Overload (Excess Iron Supplementation)

What it is

Iron is essential but supplementing when not needed can cause “iron overload”.

How it harms

  • The liver stores excess iron (in ferritin/hemosiderin). Over time this can cause liver inflammation, fibrosis, cirrhosis.

  • Kidneys: Iron excess creates oxidative stress and may damage glomeruli or tubules; though less directly, overload conditions can affect kidney structure.

Key risk factors

  • Taking iron supplements without iron deficiency or doctor supervision.

  • Genetic conditions like haemochromatosis (iron-storage disease).

How to protect yourself

  • Test ferritin and transferrin saturation before supplementing iron.

  • Avoid taking iron when not needed.

  • If supplementing, ensure periodic check of liver function.

4. High doses of Vitamin C (Especially in certain forms)
