Activated charcoal capsules help detoxify the body by binding to toxins and chemicals in the gut, aiding their removal. They are commonly used to relieve gas, bloating, and digestive discomfort. In emergency cases, they can absorb poisons and overdoses, preventing absorption into the bloodstream. Additionally, they may support kidney function by filtering waste and toxins. While beneficial for occasional use, it's important to consult a healthcare professional before regular consumption.
