A pilot study on the ability of clinoptilolite to absorb ethanol in vivo in healthy drinkers: effect of gender.

Zeolites are microscopic minerals of volcanic origin, and the zeolite most commonly used in medicine is clinoptilolite. Over the years, clinoptilolite has been tested in several ways: as an antioxidant, as an adjuvant in anticancer therapy due to its ability to capture chemotoxins, as an antidiarrhoeal agent and as a chelating agent for heavy metals. The aim of this study was to evaluate the ability of clinoptilolite to absorb ethanol in vivo in healthy drinkers. We enrolled 12 healthy drinkers in this study. The study was conducted as follows: phase 1: consumption of a hydroalcoholic solution containing 25 g of ethanol; phase 2: use of a 16.25 mL medical device containing clinoptilolite (2.5 g of clinoptilolite within a single-dose sachet) + consumption of a hydroalcoholic solution containing 25 g of ethanol; phase 3: use of a 32.5 mL medical device (5 g of clinoptilolite within a single-dose sachet) + consumption of a hydroalcoholic solution containing 25 g of ethanol. At the time of blood sampling, alcohol ingestion was also measured using an Alcolmeter instrument, and the results showed that the two methods overlapped. Reductions of 43%, 35%, 41% and 34% in blood ethanol at 30, 60, 90 and 120 minutes, respectively, were observed after the consumption of 5 g of clinoptilolite + 25 g of ethanol in both males and females, whereas the consumption of 2.5 g of clinoptilolite did not result in a statistically significant reduction in blood ethanol. In particular, the blood ethanol reduction was more significant in males. Our study highlights and confirms the ability of clinoptilolite to decrease the absorption of ingested ethanol by reducing blood alcohol levels. This effect was statistically significant at a dose of 5 g.
