The best thing to take for bloating depends on what’s causing it. Gas from fermented food in your gut, slow digestion, constipation, and fluid retention all produce that uncomfortable fullness, and each responds to different remedies. The good news is that most occasional bloating can be managed with over-the-counter products, digestive enzymes, or a few well-supported herbal options.
Why Bloating Happens in the First Place
Understanding the cause helps you pick the right remedy. Most bloating comes from one of three things: excess gas, sluggish digestion, or fluid retention.
Gas builds up when bacteria in your intestines ferment carbohydrates that weren’t fully absorbed earlier in digestion. The more undigested carbs that reach your lower gut, the more gas those bacteria produce. Certain foods (beans, cruciferous vegetables, some dairy) are especially prone to this. In some cases, bacteria that normally live in the colon migrate into the small intestine, a condition called SIBO, which ramps up fermentation even further.
Slow-moving digestion is another common culprit. When food lingers in your stomach or intestines longer than it should, whether from constipation, a heavy meal, or a motility issue, it creates pressure and distension. Backed-up stool in the colon forces recently digested food to sit and wait, producing more gas along the way.
Hormonal fluid retention also plays a role, especially around menstruation. When estrogen spikes and progesterone drops, your body holds onto water, and you feel it in your abdomen.
Simethicone for Trapped Gas
If your bloating feels like pressure from gas that won’t move, simethicone is the most widely available over-the-counter option. It works by combining small gas bubbles in your gut into larger ones that are easier to pass. You’ll find it sold as Gas-X, Mylicon, and store-brand equivalents in capsules, chewable tablets, and liquid form.
The typical adult dose is 40 to 125 mg taken after meals and at bedtime, up to four times a day. The maximum is 500 mg in 24 hours. Simethicone doesn’t prevent gas from forming. It just helps you expel what’s already there, so it works best as a reactive remedy when you’re already feeling bloated.
Digestive Enzymes for Specific Foods
When bloating reliably shows up after eating certain foods, an enzyme supplement taken with the meal can stop the problem before it starts.
Alpha-Galactosidase (Beano)
Beans, lentils, broccoli, cabbage, and root vegetables contain a type of fiber your body can’t break down on its own. That fiber passes into your lower intestine intact, where bacteria ferment it and produce gas. Alpha-galactosidase, the enzyme in Beano, breaks down that fiber before it ever reaches those bacteria. You take it with your first bite of the triggering food. It won’t help with bloating from other causes, but for plant-heavy meals it can make a noticeable difference.
Lactase for Dairy
If dairy is your trigger, the issue is likely low levels of lactase, the enzyme that breaks down milk sugar. Lactase supplements (sold as Lactaid and similar brands) supply what your body doesn’t make enough of. The standard dose ranges from 3,000 to 9,000 units taken with a meal containing dairy. If you’re still eating dairy 30 to 45 minutes later, you may need a second dose. These work well for people with confirmed or suspected lactose intolerance but won’t help with bloating from other sources.
Peppermint Oil for Crampy Bloating
Peppermint oil acts as an antispasmodic, meaning it relaxes the smooth muscle lining your digestive tract. This is particularly useful when bloating comes with stomach cramps, tightness, or the sensation that gas is trapped and can’t move. The NHS lists peppermint oil as a recognized medicine for relieving stomach cramps, bloating, and flatulence.
Look for enteric-coated capsules specifically. The coating prevents the oil from dissolving in your stomach (which can cause heartburn) and delivers it to your intestines where it’s needed. You take it before meals. Peppermint oil is one of the better-studied natural options for people with irritable bowel syndrome who deal with bloating regularly.
Ginger for Slow Digestion
If your bloating feels like food is just sitting in your stomach, ginger may help. The active compound in ginger root improves gastric motility, which is the rate at which food leaves your stomach and moves through the rest of your digestive tract. Faster transit means less time for food to ferment and less pressure building up. According to Johns Hopkins Medicine, eating ginger can cut down on fermentation, constipation, and other causes of bloating and intestinal gas.
You can get this benefit from fresh ginger steeped in hot water as tea, from ginger chews, or from standardized ginger capsules. The advantage of ginger over simethicone is that it addresses the underlying slowness rather than just helping you pass gas after the fact.
Probiotics for Recurring Bloating
Probiotics take a different approach. Instead of treating a single episode, they aim to shift the balance of bacteria in your gut over time, which can reduce how much gas your intestines produce in the first place. Not all strains are equal, though.
A large meta-analysis published in The Lancet’s eClinicalMedicine reviewed multiple probiotic strains and found that nine out of fourteen probiotic types studied showed significant improvement in at least one symptom of irritable bowel syndrome, including bloating. Specific strains with the strongest evidence include Bifidobacterium infantis 35624 and Bifidobacterium animalis DN-173010. These aren’t overnight fixes. Most people need several weeks of daily use before noticing a change, and the benefits tend to fade if you stop taking them.
If you’re trying probiotics, look for a product that lists specific strain names (including the alphanumeric code after the species name) rather than just a generic “probiotic blend.” The strain matters more than the total colony count.
Movement That Helps Right Now
Sometimes the fastest relief doesn’t come from a pill. Physical movement helps relax the muscles around your abdomen, lower back, and hips, which can release trapped gas surprisingly quickly. A short walk after a meal is one of the simplest and most effective options.
Several yoga-style positions are especially useful. Knee-to-chest pose (lying on your back and pulling one or both knees toward your chest) stretches the lower back and creates gentle abdominal pressure. Child’s pose relaxes the hips and lower back. Lying twists, where you bend your knees and rotate your hips side to side while on your back, help move gas through the intestines. Even a deep squat held for 30 seconds can help. The UK’s National Health Service also recommends massaging your abdomen from right to left, following the path of your colon, to encourage gas to move along.
Matching the Remedy to Your Type of Bloating
The most common mistake is grabbing a generic “bloating relief” product without thinking about the cause. Here’s a quick guide:
- Bloating after beans, vegetables, or high-fiber meals: alpha-galactosidase taken with food
- Bloating after dairy: lactase enzyme taken with dairy
- Bloating with gas pressure that won’t pass: simethicone after meals
- Bloating with cramps or tightness: enteric-coated peppermint oil before meals
- Bloating from food sitting heavy in your stomach: ginger before or with meals
- Chronic, recurring bloating: a targeted probiotic strain taken daily for several weeks
- Premenstrual bloating from water retention: reducing sodium intake and staying hydrated, since gas remedies won’t address fluid-based bloating
Some people feel bloated even when their gas volume is completely normal. This is called visceral hypersensitivity, where the nerves in your gut overreact to normal amounts of stretching. If you’ve tried multiple remedies without improvement, that heightened nerve sensitivity could be the issue, and it responds better to approaches that calm the gut-brain connection (like low-dose antispasmodics or stress management) than to enzyme supplements or simethicone.
Bloating that comes and goes with meals and resolves within a few hours is almost always benign. Bloating that’s constant, progressively worsening, or paired with unintentional weight loss, severe pain, or visible swelling that doesn’t go down warrants a medical evaluation. Persistent abdominal fluid buildup can signal liver, kidney, or heart problems that need treatment beyond what any supplement can provide.
