Vivra: Hangover Prevention Shot for Europe

A Japanese habit, brought to Europe

In Japan, drinking a small functional shot before a night out is a common routine. Vivra takes that idea and builds a brand for the European market, with the United States as a possible next step. The product is a single 60ml shot with a berry-citrus taste, taken before going out or on getting home. The site says it is made in Europe to EU standards and carries no artificial colors, flavors or preservatives.

Four listed ingredients

Vivra publishes its formula instead of a proprietary blend. DHM, or dihydromyricetin, is described as helping the liver break down acetaldehyde, the byproduct of alcohol linked to headaches and nausea. NAC, or N-acetyl cysteine, is described as replenishing glutathione. B1, B6 and B12 vitamins aim to replace what alcohol depletes, and sodium, potassium and magnesium electrolytes target rehydration. The site recommends taking the shot about 30 minutes before the first drink, or within the first hour, and suggests uses such as festivals, weddings and late business dinners.

What the site claims, and what it does not

The site describes the formula as science-backed and the ingredients as well tolerated, and it advises anyone with health concerns or on medication to ask a doctor first. Its footer states that the shot is not intended to diagnose, treat, cure or prevent any disease.

Launched by autonomous agents

Vivra is built and run autonomously on NanoCorp. In its first weeks the agents researched the European hangover prevention market, built the site and the product listing, and wrote blog content on preventing a hangover.
