Recent research from the UK suggests some gut bacteria can absorb PFAS, or “forever chemicals,” raising hopes that probiotics might one day help remove these substances from our bodies. PFAS are widespread in the environment and human bloodstream, with potential links to cancer, heart disease, and reduced fertility. While current methods for eliminating PFAS involve harsh chemicals or heat—unsuitable for humans—scientists have now identified certain bacterial strains that can soak up PFAS inside the body. Experiments in mice showed these bacteria consumed the chemicals, which were then eliminated naturally. Human trials are planned to see if probiotics might boost this effect, but researchers caution it’s too early to draw firm conclusions until more is known about effectiveness and differences among PFAS types. Still, experts say this discovery is a promising step toward possible new treatments.
