Zbiotics targets acetaldehyde, not ethyl alcohol. From the article:
> The gel shifts the breakdown of alcohol from the liver to the digestive tract. In contrast to when alcohol is metabolised in the liver, no harmful acetaldehyde is produced as an intermediate product,” explains Professor Raffaele Mezzenga from the Laboratory of Food & Soft Materials at ETH Zurich. Acetaldehyde is toxic and is responsible for many health problems caused by excessive alcohol consumption.
Using this gel would manifest as simply not being as intoxicated, whereas Zbiotics is intended to allow for intoxication but prevent the hangover afterwards.
