That headline is dramatic on purpose — but there is real science behind it when context is added. Vitamins and supplements don’t “destroy” organs overnight, but misuse, high doses, or long-term unsupervised use can seriously damage the liver and kidneys, especially in older adults.
Here’s the accurate, no-nonsense list 👇
