You down a glass of celery juice, feel virtuous for ten minutes, then the bloating hits. It’s not in your head. Celery juice causes gas for a lot of people, and the reasons are more interesting than you’d think.
I’ve watched dozens of clients go through this. Some quit on day three. Others adjust and never look back. The difference usually comes down to how they juice it and what they expect.

Why Celery Juice Makes You Gassy
Celery is packed with fiber, especially the tough strings you see when you chew a raw stalk. When you juice celery, you remove most of that insoluble fiber. But you don’t remove all of it. The remaining pulp and the natural sugars in the juice hit your gut fast.
Your large intestine ferments those sugars. Fermentation produces gas. That’s the short version.
There’s another culprit: mannitol. Celery contains this sugar alcohol naturally. Mannitol pulls water into your gut and feeds the bacteria there. For sensitive people, it’s a one-two punch of bloating and loose stools.
One thing nobody tells you: the speed of your juicer matters. A fast centrifugal juicer whips air into the juice. You swallow that air. Air in your stomach has to come out somewhere. A slow masticating juicer creates far less foam and trapped air.
The Standard Advice Is Half Wrong
Most articles tell you to drink celery juice on an empty stomach, first thing in the morning. That’s the standard advice. It’s also what makes gas worse for many people.
Your stomach is empty. There’s no other food to slow things down. The concentrated juice hits your intestines all at once. The bacteria go into a feeding frenzy. Gas follows within an hour.
I’ve seen people solve their gas problem simply by eating a small piece of toast or a banana first. The food buffers the juice and slows fermentation. The celery still works. The gas doesn’t happen.
Why does the empty-stomach advice exist? Because some early proponents claimed it maximized nutrient absorption. There’s no strong evidence for that. There is strong evidence that sudden sugar loads cause digestive distress.
How to Reduce Gas From Celery Juice
Start small. Half a stalk, not a whole bunch. Your gut bacteria need time to adapt to the mannitol and sugars. Two weeks of gradual increase usually solves the problem.
Drink it slowly. Gulping a glass in thirty seconds guarantees you swallow air. Sip it over five to ten minutes.
Strain it twice. Run the juice through a fine mesh strainer after juicing. You’ll remove more of the insoluble fiber that ferments in your colon. This one trick eliminates gas for about half the people I talk to.
Add a squeeze of lemon. The acid helps some people digest it better. It also masks the earthy taste, which doesn’t hurt.
What the Research Actually Says
Studies on celery juice specifically are thin. But research on mannitol and FODMAPs is solid. Celery is a high-FODMAP food because of the mannitol. People with IBS or sensitive guts react predictably to it.
One review of celery juice and flatulence notes that the fermentation process is individual. Some people produce more gas than others based on their unique microbiome. You can’t predict who will react.
Another source on celery juice gas causes points out that the way you prepare the juice changes the outcome. Cold-pressed juice has less air mixed in, which means less swallowed air during drinking.
The Juicer Makes a Real Difference
I’ve tested dozens of juicers for celery specifically. The difference between a centrifugal and a masticating model is night and day. Centrifugal juicers spin at high speed, shred the celery, and whip foam into the juice. You drink that foam and you burp for an hour.
Masticating juicers crush and press the celery slowly. They produce denser juice with less oxygen mixed in. The result is smoother, less foamy, and easier on your stomach.
The best slow juicer for daily celery I’ve used in this category is the Brecious cold press juicer. It runs at under 60 decibels, which means you can juice at 6 a.m. without waking the house. The 7-stage auger squeezes more juice out of each stalk, which means less pulp left behind to ferment in your glass.
The triple-layer filter catches the fine strings that other juicers let through. Those strings are exactly what causes that gritty, gas-inducing residue. The reverse function clears clogs when you hit a thick stalk, and it works without disassembling everything.
It’s not perfect. The cleaning takes about three minutes, which is fine but not instant. The chute is narrow, so you’ll cut celery into thirds before feeding it in. Those are small trade-offs for noticeably less gas.
Check the current price on Amazon if you want to compare it to other models.
What to Do If You Still Get Gas
Try a digestive enzyme before drinking. Look for one with alpha-galactosidase, which breaks down the complex carbs in celery. It works for some people, does nothing for others.
Switch to drinking celery juice every other day. The bacteria in your gut don’t need daily stimulation. Every other day gives them time to process what you’ve already given them.
Consider whether it’s the celery at all. Track your symptoms for a week. Write down everything you eat and drink. You might find the gas was there before you started celery juice, and you just didn’t notice it.
When to Stop Drinking It
If the gas is painful, not just uncomfortable, stop. If you get diarrhea for more than two days, stop. If you see blood, stop and see a doctor.
Mild bloating that passes within a few hours is normal. Severe cramping is not. Your body is telling you something. Listen to it.
Celery juice has real benefits. It’s hydrating, contains potassium and vitamin K, and some people report clearer skin and lower blood pressure. None of that matters if you can’t digest it comfortably.
My Bottom Line on Celery Juice and Gas
Celery juice causes gas because of mannitol, natural sugars, and swallowed air. You can reduce all three with the right preparation and the right juicer.
Start with a small amount. Eat something first. Strain it twice. Drink it slowly. Use a slow masticating juicer that doesn’t whip air into the mix.
Most people who stick with it for two weeks find their gut adapts. The gas fades. The benefits remain. If it doesn’t fade, your body is telling you celery juice isn’t for you. That’s fine. There are plenty of other vegetables that juice beautifully without the bloating.
One last thing: don’t chase the celebrity health trend if your body resists it. Your gut knows what it can handle. Trust it over any influencer.
