ZBiotics is a company that produces a probiotic drink designed to alleviate hangover symptoms. The product is made from Bacillus subtilis, a common probiotic found in honey and Japanese soy products like miso and tempeh. The company claims that their product can help break down acetaldehyde, a toxic byproduct of alcohol metabolism, which is often associated with hangovers. The product has been safety-tested and is FDA-compliant. It has been reviewed and tested by various sources, and while individual experiences may vary, many customers seem to find it effective. However, it's important to note that the product is relatively expensive, with a price tag of $9-$12 per bottle. As always, it's recommended to consult with a healthcare professional before starting any new supplement regimen.
