Detoxification is a critical biological process that helps remove metabolic waste, environmental toxins, hormones, and pathogens. When this system is sluggish or overwhelmed, toxins can accumulate, leading to symptoms like headaches, rashes, fatigue, and chemical sensitivity. Contributing factors may include genetic variants (like MTHFR or GST), liver congestion, nutrient deficiencies, mold or heavy metal exposure, and poor gut or bile flow. Functional medicine uses testing and protocols to support the liver’s two detox phases, enhance elimination through bowels and lymph, and restore the body's natural capacity to clear toxins safely and effectively.
