It sounds like a joke, but it isn’t.
In Spain, individuals are selling capsules made from human fecal matter on the Internet and social media, promising that they are ‘natural,’ ‘safe,’ or that they come from ‘healthy donors.’ The National Transplant Organization and the Spanish Society of Infectious Diseases issued a joint statement on September 4, 2026, to stop this practice before someone gets hurt.
There is a real treatment called fecal microbiota transplantation, which does help restore intestinal bacteria in very specific cases, such as infections resistant to antibiotics. But this procedure requires rigorous donor screening, clinical processing, and constant medical supervision. None of that happens when someone sells you a jar via private message.
The authorities were clear: preparing feces to give to another person is not the same as making a homemade supplement, and it can transmit serious diseases. If you see this online, the recommendation is simple: don’t buy, don’t consume, and report it.
