Iron is one of the most commonly recommended supplements for fatigue, anemia, and low ferritin. But what if increasing iron is sometimes the exact thing that allows harmful microbes to thrive? In this episode of Wholistic Living, we explore the lesser-known connection between iron and pathogen growth. Many bacteria, fungi, and parasites depend on iron to replicate, strengthen biofilms, and become more resistant to the immune system.You will learn:• Why many pathogens actively compete with your body for iron• How excess iron can support bacterial and fungal overgrowth• The link between iron, biofilm formation, and chronic infections• Why some people feel worse after taking iron supplements• When iron supplementation may actually be appropriate• Functional medicine considerations for balancing iron and gut healthIf you struggle with chronic gut issues, persistent infections, Candida, or symptoms that never seem to resolve, iron metabolism may be an overlooked piece of the puzzle.
