Each serving gives you 560mg of **Activated Charcoal**, which sits right at the low end of the studied range. The label recommends 2-3 servings daily — at two servings (1,120mg), you're hitting the EFSA-approved dose for reducing intestinal gas (1g before and after a gas-producing meal). At three servings, you reach 1,680mg, comfortably within the clinical range. The evidence behind charcoal for digestive comfort is limited but real: one double-blind trial showed reduced gas and bloating, and EFSA has approved the gas-reduction claim at adequate doses.
The biggest thing to know before buying: **Activated Charcoal** adsorbs indiscriminately. It will bind medications, vitamins, and other supplements you take within 1-2 hours, reducing their absorption. The label's direction to take it 3-4 hours away from meals and other supplements is critical — ignore that spacing and you risk neutralizing whatever else you're taking.
