Hangover cure
There is no cure for a hangover. What the evidence says about water, electrolytes, food, sleep and the few nutrients with any trial data, written honestly.
What is usually behind it
There is no cure for a hangover, and this page will not pretend otherwise. Time, water, food, and sleep do most of the work. Alcohol dehydrates, lowers blood sugar, disturbs sleep, and lowers heart rate variability for the night (evidence).
Nutrients with any honest trial data are few: electrolytes for the fluid loss; B vitamins and magnesium, which alcohol uses up, contribute to the reduction of tiredness and fatigue; N-acetyl cysteine has a small human trial base as a precursor to glutathione. What to skip: anything sold as a cure.
See a GP if you are drinking most days, if you cannot remember what you drank, or if you need a drink to feel normal.
