Research suggests that bentonite clay, when formulated as a nasal spray barrier agent, may help reduce viral load in nasal tissue under laboratory conditions, though this evidence comes from a single in vitro study using a three-dimensional human nasal tissue model rather than clinical trials in humans. Studies indicate that the clay-based spray tested did not appear to harm nasal tissue or disrupt its protective functions, and demonstrated notable reductions in viral levels both before and after simulated exposure. The available evidence is limited to one preclinical laboratory study with a neutral research direction, meaning it neither strongly advocates for nor dismisses the intervention, and findings from tissue models do not always translate to real-world outcomes in living people. Readers should be aware that this body of evidence is too preliminary to draw firm conclusions about bentonite clay's effectiveness for skin or respiratory health in humans.
