Vitamins and supplements are often seen as harmless, but taking them in excessive doses, mixing them improperly, or using them without medical guidance can stress the liver and kidneys. These organs are responsible for filtering toxins, so overload can lead to serious problems.
Problems usually arise from high doses over long periods, hidden ingredients, or combining supplements with medications. Awareness and moderation are key.
Supplements that may pose risks when overused:
- Vitamin A (high doses can be toxic to the liver)
- Vitamin D (excess may raise calcium and strain kidneys)
- Niacin (Vitamin B3) at high doses can affect liver function
- Iron (overload can damage liver and kidneys)
- Calcium supplements (excess may contribute to kidney stones)
- Green tea extract (concentrated forms linked to liver injury)
- Kava (associated with liver toxicity)
- Turmeric/curcumin supplements in very high doses
- Bodybuilding or “detox” blends with undisclosed ingredients
