Colon cleansing is also known as detoxification. Everything we ingest forms toxins in our bodies and over time, those toxins can build up, causing health concerns. If youâre suffering from acne, headaches, candida, constipation, weight gain, or even general fatigue, toxin buildup could be to blame. Colon cleansing can remedy these ailments and leave you feeling refreshed and at the top of your game.
