Activated charcoal is a fine black powder made by heating carbon-rich materials like coconut shells or wood at very high temperatures, creating a highly porous substance known for its ability to trap certain compounds in the gut before they are absorbed. Research suggests that activated charcoal may help reduce bloating and intestinal gas by binding to gas-producing byproducts during digestion, though findings have been mixed across studies. Some preliminary research has explored its potential role in supporting recovery after alcohol consumption by adsorbing certain congeners, although it does not significantly affect blood alcohol levels themselves. In oral care, studies indicate that charcoal-based powders and toothpastes may help with surface stain removal, though dental professionals note that evidence for long-term whitening or protective benefits remains limited. Available primarily as capsules or loose powder, activated charcoal continues to attract scientific interest as both a folk remedy and a subject of modern investigation.
