L-cysteine is an amino acid naturally found in protein-rich foods.
However, while participantsdidreport reduced hangover symptoms, the study resultsdid notsupport this hypothesis.
Alcohol absorption rates were similar between those who took L-cysteine supplements and those who took placebos.
The only definitive way to prevent a hangover is to limit the amount of alcohol you drink.
