Our bodies are enzyme engines. Every physiological function depends on enzymes to manufacture molecules, produce energy, and create cell structures. Toxins damage enzymes and thus undermine countless bodily functions—inhibiting the production of hemoglobin in the blood, for example, or lowering the body’s capacity to prevent the free-radical damage that accelerates aging.

Toxins poison enzymes so they don’t work properly.
