What you should take for bloating depends on what’s causing it. A buildup of trapped gas, a reaction to specific foods, sluggish digestion, and chronic gut sensitivity all respond to different remedies. The good news is that most occasional bloating improves with something you can pick up at a pharmacy or grocery store, no prescription needed.
Simethicone for Trapped Gas
If your bloating feels like pressure or fullness from gas that won’t move, simethicone is the most straightforward fix. It works by breaking up gas bubbles in your digestive tract so they’re easier to pass. You’ll find it sold as Gas-X, Mylicon, and various store brands.
The standard dose for adults is 40 to 125 mg taken four times a day, after meals and at bedtime, with a maximum of 500 mg in 24 hours. Chewable tablets can also be taken as 150 mg three times daily after meals. Simethicone isn’t absorbed into your bloodstream, so side effects are rare. It works best for bloating you’re experiencing right now rather than preventing future episodes.
Digestive Enzymes for Food-Triggered Bloating
Some bloating happens because your body can’t fully break down certain foods, and undigested material ferments in your intestines, producing gas. Two enzyme supplements target the most common culprits.
Alpha-galactosidase (Beano) breaks down the complex carbohydrates found in beans, lentils, broccoli, cabbage, and root vegetables before they reach your intestines. More than 20% of people experience gas pain from these foods, according to Harvard Health. The key is timing: you need to take it right before your first bite, not after symptoms start. Once fermentation is underway, the enzyme can’t undo it.
Lactase (Lactaid) helps if dairy is your trigger. It supplies the enzyme your body is short on, breaking down lactose so it doesn’t sit in your gut and produce gas. Like Beano, take it just before eating dairy for it to work.
Peppermint Oil for Cramping and Fullness
Peppermint oil relaxes the smooth muscle lining your digestive tract, which can ease the tight, distended feeling that comes with bloating. It also appears to calm overactive nerve signaling in the gut. A Dutch clinical trial of 190 patients with irritable bowel syndrome tested 182 mg capsules of peppermint oil taken daily for eight weeks and measured improvements in bloating, cramping, and overall abdominal discomfort.
Look for enteric-coated capsules specifically. The coating prevents the oil from dissolving in your stomach, where it can cause heartburn, and delivers it to your intestines where it’s most useful. Peppermint tea is gentler but less concentrated, so it may help mild bloating without the potency of a capsule.
Probiotics for Recurring Bloating
If bloating is a regular problem rather than an occasional nuisance, a probiotic may help over time. Not all strains are equal here. The most studied strain for bloating is Bifidobacterium infantis 35624, which has shown measurable reductions in bloating scores across multiple clinical trials in people with IBS. It’s sold under the brand Align.
Probiotics aren’t a quick fix. They work by gradually shifting the balance of bacteria in your gut, and most people need several weeks of consistent use before noticing a difference. If you try one strain for four to six weeks without improvement, switching to a different strain is reasonable since gut bacteria are highly individual.
When Constipation Is the Real Problem
Bloating and constipation often travel together. When stool moves slowly through your colon, bacteria have more time to ferment what’s sitting there, producing extra gas. If you’re not having regular bowel movements, treating the constipation often resolves the bloating too.
Fiber supplements like psyllium husk (Metamucil) add bulk that helps move things along, though they can temporarily increase gas if you ramp up too quickly. Start with a small dose and build up over a week or two. Staying well hydrated matters here since fiber without enough water can make constipation worse. Osmotic laxatives like polyethylene glycol (MiraLAX) work by drawing water into the colon to soften stool. They’re effective for constipation but can themselves cause bloating and cramping, so they’re better suited as a short-term solution while you address the underlying cause with diet changes.
Simple Habits That Reduce Bloating
Sometimes bloating isn’t about what you take but what you change. Eating quickly, chewing gum, drinking through straws, and talking while eating all cause you to swallow air, which accumulates in your digestive tract. Slowing down at meals and cutting back on carbonated drinks can make a noticeable difference within days.
Large meals stretch the stomach and slow digestion, giving bacteria more time to produce gas. Eating smaller, more frequent meals keeps your system moving without overwhelming it. If you’ve recently increased your fiber intake, whether through whole grains, legumes, or a supplement, your gut microbiome needs time to adjust. The bloating that comes with a fiber increase typically eases after two to three weeks as your bacteria adapt.
Keeping a simple food diary for a week or two can help you spot patterns. Common triggers beyond beans and dairy include onions, garlic, apples, wheat, and sugar alcohols (the sweeteners ending in “-ol” found in sugar-free gum and protein bars). Identifying your personal triggers lets you use the right enzyme or avoid the food entirely rather than guessing.
Signs Your Bloating Needs Medical Attention
Occasional bloating after a big meal or a bowl of beans is normal. Persistent bloating that doesn’t respond to any of the approaches above, or bloating paired with certain other symptoms, points to something that needs evaluation. The American Academy of Family Physicians flags these warning signs alongside bloating: unintentional weight loss, blood in your stool, difficulty or pain when swallowing, fever, jaundice (yellowing of your skin or eyes), vomiting, or progressive abdominal pain that keeps getting worse. New-onset bloating in people 55 and older also warrants a closer look, particularly if there’s a family history of gastrointestinal or ovarian cancer.
Bloating that comes with severe diarrhea, especially if it’s bloody, happens at night, or doesn’t improve when you skip meals, is another reason to get checked. These patterns can signal conditions like celiac disease, small intestinal bacterial overgrowth (SIBO), or inflammatory bowel disease, all of which have specific treatments that over-the-counter remedies won’t address.
