Do Sulphites Really Cause Hangovers? The Truth You Need to Know

When you wake up after a night of wine and wake up with that pounding head, dry mouth, and regret—you might have blamed the sulphites. After all, “contains sulphites” is printed on almost every wine label. But are sulphites really the culprit behind hangovers?

Spoiler alert: it’s not the sulphites.

What Are Sulphites Anyway?

Sulphites (or sulfites) are preservatives used in food and drinks, especially wine, to prevent spoilage and maintain flavor. They’re naturally present in some foods (like dried fruit and soy sauce), but winemakers often add extra to keep bottles fresh.

In most people, sulphites don’t cause hangovers—they can, however, trigger allergic-like reactions in a very small group of people, usually those with asthma. Think rashes, wheezing, or hives—not hangovers.

So What Actually Causes Hangovers?

Your hangover is more likely due to:

• Alcohol metabolism – When your body breaks down alcohol, it creates acetaldehyde, a toxic byproduct that causes nausea and headaches.
• Dehydration & electrolyte imbalance – Alcohol makes you pee more, leaving you dry and depleted.
• Congeners – These chemical byproducts, found in darker drinks like red wine and whiskey, worsen hangovers.
• Inflammation & oxidative stress – Drinking disrupts your body’s balance, making recovery harder.

That splitting headache after red wine? It’s probably the combination of congeners, histamines, and dehydration—not the sulphites.

Why the Sulphite Myth Persists

Wine labels legally have to declare sulphites, so they’ve become the scapegoat. But fun fact: dried fruits can have 10x more sulphites than wine, and yet most people don’t wake up hungover from a pack of raisins.

How to Actually Prevent Hangovers

If you want to feel better the morning after, skip blaming sulphites and start supporting your body instead:

• Hydrate before, during, and after drinks.
• Eat before you drink (food slows alcohol absorption).
• Pace yourself—your liver can only handle so much.
• Add supplements that help your body break down alcohol faster.
