Sprite is not a proven hangover cure, despite headlines that made the rounds a few years ago. The claim traces back to a real lab study, but the actual data tells a more complicated story. Sprite performed modestly at best, and plain soda water outperformed it on the measure that matters most for hangover recovery.
Where the Sprite-Hangover Claim Comes From
In 2013, researchers at Sun Yat-sen University in China tested 57 different beverages to see how they affected the enzymes your liver uses to break down alcohol. The study measured two key enzymes: one that converts alcohol into acetaldehyde (a toxic byproduct responsible for many hangover symptoms) and another that breaks acetaldehyde down into harmless acetic acid. The faster that second enzyme works, the quicker your body clears the compound that makes you feel terrible.
Sprite got the headlines, but it wasn’t actually the star of the study. Sprite reduced activity of both enzymes by about 15%, meaning it slightly slowed the entire process. The beverages that genuinely boosted the breakdown of acetaldehyde were iced black tea and soda water, each increasing that critical enzyme’s activity by roughly 21%. Meanwhile, several “healthy” drinks performed far worse. Jasmine tea inhibited the acetaldehyde-clearing enzyme by about 42%, and fresh orange juice inhibited it by about 44%, potentially prolonging the most unpleasant phase of a hangover.
Why Acetaldehyde Matters
Your liver processes alcohol in two steps. First, it converts ethanol into acetaldehyde, which is significantly more toxic than alcohol itself. Then a second enzyme converts acetaldehyde into acetic acid, which is harmless. When that second step gets slowed down, acetaldehyde builds up in your system, intensifying nausea, headache, rapid heartbeat, and flushing.
This is why boosting the second enzyme is the goal. And it’s why the finding about jasmine tea and orange juice was arguably more important than anything about Sprite. If you reach for orange juice the morning after heavy drinking, you could theoretically be making things worse by letting acetaldehyde linger longer.
What Sprite Actually Contains
A 12-ounce can of Sprite has about 33 grams of sugar and 33 milligrams of sodium. It contains trace amounts of potassium, calcium, and magnesium, but nothing close to what you’d get from an electrolyte drink or even a glass of milk. It has no caffeine and no vitamins.
The sugar does provide quick energy, which can help if you haven’t eaten, and the fluid contributes to rehydration. But Sprite is not an effective rehydration tool on its own. Alcohol suppresses the hormone that tells your kidneys to retain water, so you lose fluids and electrolytes throughout a night of drinking. Replacing those losses requires sodium and potassium in meaningful amounts, which Sprite simply doesn’t deliver.
Does Carbonation Help or Hurt?
Some people swear that the fizz in Sprite settles their stomach. Research on carbonated water found that carbonation doesn’t change how quickly your stomach empties, so it won’t speed up or slow down absorption of anything you eat or drink alongside it. What carbonation does change is how food and liquid distribute inside your stomach, which may explain why some people feel temporary relief from nausea while others find bubbles make their stomach feel worse.
If you’re already dealing with acid reflux or an irritated stomach lining from alcohol, carbonation can add to the discomfort. A flat or still beverage is generally a safer bet when your gut is already inflamed.
Better Options for Hangover Recovery
Based on the same study that gave Sprite its reputation, soda water is the smarter carbonated choice. It boosted the acetaldehyde-clearing enzyme by 21% and contains no sugar that could further upset your stomach. Iced black tea performed equally well on enzyme activity and also provides mild caffeine, which can help with headache.
Beyond those findings, the most effective hangover strategy is straightforward rehydration with electrolytes. Sports drinks, coconut water, or even broth provide the sodium and potassium your body actually needs to recover. Eating bland, easy-to-digest food helps stabilize blood sugar, which drops after heavy drinking and contributes to that shaky, weak feeling the next morning.
What you want to avoid may be just as important. The study found that cola reduced acetaldehyde-clearing enzyme activity by about 30%, and several herbal teas performed even worse. The popular remedy of honey citron tea also inhibited the enzyme, potentially prolonging symptoms. Not every “natural” or “healthy” drink helps, and some may actively work against your recovery.
The Bottom Line on Sprite
Sprite won’t make a hangover worse in any dramatic way, but it’s not a meaningful remedy either. Its enzyme effects were modest and mixed, its electrolyte content is negligible, and its sugar content is high enough to potentially aggravate nausea. If you’re reaching for something carbonated, soda water is the better pick. If you want to recover as quickly as possible, focus on fluids with actual electrolytes, light food, and time. Your liver does the real work, and no beverage on a store shelf can rush that process by much.
