Preventing a hangover: what really
happens in your body (and what helps)
vs. alcohol itself
per glass of alcohol
acetaldehyde-neutralization
A hangover is more than just an annoying morning. It is a series of physiological reactions that your body undergoes as a result of alcohol processing — and the liver plays a central role in this. In this article, we explain what happens at the molecular level and which strategies are scientifically supported.
A hangover is not a singular phenomenon. It is the result of multiple simultaneous processes:
Toxic byproduct of alcohol breakdown — 10–30× more toxic than alcohol
Alcohol suppresses ADH hormone → 100–150 ml extra urine production per glass
Alcohol activates pro-inflammatory cytokines → muscle pain, fatigue
The more alcohol you drink, the faster the glutathione reserves deplete — and the longer acetaldehyde remains circulating in the body. The liver's protective capacity becomes exhausted, causing the hangover to worsen not linearly but exponentially.
| Factor | Effect on hangover |
|---|---|
| Genetic variations in ADH and ALDH2 | Determines how quickly acetaldehyde is broken down |
| Glutathione reserves | Higher reserves = faster neutralization of acetaldehyde |
| Age (40+) | Glutathione production decreases with age |
| Nutritional status | On an empty stomach, alcohol is absorbed faster |
| Sleep quality | Alcohol disrupts REM sleep, which hinders recovery |
- NAC (N-acetylcysteine) — stimulates glutathione production, helps the liver neutralize acetaldehyde faster
- Enough water — 1 glass of water per glass of alcohol reduces the dehydration component
- Eating before drinking — fat and protein-rich foods slow alcohol absorption and lower peak concentration
- Replenishing electrolytes — sodium, potassium, and magnesium are lost with alcohol consumption
- Milk thistle (silymarin) — supports liver regeneration in the long term
- Coffee — masks fatigue but does not speed up alcohol breakdown and can worsen dehydration
- "Drinking through" — only postpones issues, the liver still has to process the alcohol
- Aspirin/ibuprofen — can worsen stomach issues and is not recommended with alcohol consumption
The most effective strategy is not reactive (after a hangover) but preventive: structurally supporting the liver so it is better able to withstand the burden of alcohol. Daily intake of NAC, glutathione, and BroccoPhane® continuously supports the liver — not just the day after a night out.
