This seems to be the most legitimate research done on a compound (amino acid L-cysteine) that will remove symptoms of an alcohol-induced hangover. The consumption of alcohol weakens the immune system and therefore might be something people might not want to have during a global pandemic, but if people do choose to consume alcohol, L-cysteine is relatively cheap to buy and (unlike many other remedies) has clinical data to support its efficacy.
Hangover Cure Successfully Tested on Drunk Subjects in Finland
A dose of 1,200 milligrams of amino acid L-cysteine was found to reduce alcohol-related nausea and headache, while a dose of 600 milligrams helped alleviate stress and anxiety, according to a study published in the journal Alcohol and Alcoholism by researchers at the University of Helsinki and the University of Eastern Finland.
The randomized, double-blind study had 19 healthy male volunteers consuming alcohol doses of 1.5 grams per kilogram over three hours in a controlled setting. The subjects were then asked to swallow placebo or L-cysteine tablets containing vitamin supplements.
Researchers say that as well as reducing or even eliminating hangovers entirely, L-cysteine also helps “reduce the need of drinking the next day,” thereby cutting the risk of alcohol addiction.
Binge drinking is common in Finland, with more than half a million Finns considered at risk from excessive drinking.
The researchers received funding from Catapult Cat Oy, which sells the L-cysteine supplements.
The study ran into certain difficulties. Some participants weren’t able to consume all the alcohol required and had to be excluded, some had such high tolerance levels that they experienced no hangover symptoms; and some were sidelined because they insisted on topping up the dose by heading for the bar, researcher Markus Metsala told local media.
