Gas and bloating can hit at the worst times - during a meeting, on a flight, or after a big meal. If you’ve ever felt like your stomach is a balloon about to pop, you’re not alone. Over-the-counter (OTC) remedies like simethicone and enzyme products are common go-tos, but they work in completely different ways. Knowing which one to use - and when - can save you from unnecessary discomfort and wasted money.
What Simethicone Actually Does
Simethicone isn’t a magic bullet that stops gas from forming. It doesn’t change your digestion or reduce the amount of gas your body makes. Instead, it tackles the symptoms. Think of it like popping bubbles in a soda. Gas in your gut is made of tiny bubbles trapped in fluid. These bubbles cause pressure, tightness, and pain. Simethicone breaks the surface tension holding those bubbles together, letting them join into bigger bubbles that are easier to pass - either as a burp or a fart.
This happens fast. Most people feel relief within 15 to 30 minutes after taking it. That’s why it’s the top pick for sudden bloating. Brands like Gas-X, Mylicon, and Phazyme all contain simethicone. A typical dose is 40 to 125 mg, taken after meals or when symptoms strike. You can take it up to four times a day, but don’t go over 500 mg total in 24 hours.
It’s safe for almost everyone - including babies, pregnant women, and seniors. Simethicone doesn’t get absorbed into your bloodstream. It just sits in your gut, does its job, and leaves. No side effects. No interactions. That’s why doctors recommend it as a first-line treatment for gas discomfort.
How Enzyme Products Work Differently
Enzyme products don’t deal with bubbles. They deal with the food that creates the gas in the first place.
Lactase, found in Lactaid and Dairy Digest, breaks down lactose - the sugar in milk and dairy. If you’re lactose intolerant, your body doesn’t make enough of this enzyme. Undigested lactose moves into your colon, where bacteria feast on it and produce gas, bloating, and cramps. Taking lactase right before eating dairy prevents this. Studies show it works in about 85% of people when used correctly.
Alpha-galactosidase, sold as Beano, targets complex carbs in beans, broccoli, cabbage, and whole grains. These carbs - called oligosaccharides - are hard for humans to digest. Bacteria in your gut ferment them, creating gas. Beano breaks them down before they reach your colon. But timing matters: you need to take it 5 to 10 minutes before eating the problem food. If you wait until after, it won’t help.
Effectiveness varies. For lactose, Beano’s success rate drops to 45-78%, depending on your gut bacteria and the food. Some people swear by it. Others notice no difference. That’s because everyone’s microbiome is unique.
Simethicone vs Enzymes: Which One Should You Use?
Here’s the simple rule: simethicone for immediate relief. Enzymes for prevention.
- Use simethicone if you’re already bloated, gassy, or uncomfortable. It’s your emergency button.
- Use enzymes if you know what’s coming - like beans at a BBQ or pizza on Friday night. Take them before you eat.
One study of 247 people showed simethicone relieved bloating in 73.5% of cases within 30 minutes. Another study found enzyme products prevented gas in 68.2% of cases - but only if taken correctly. If you forget to take Beano before your lentil soup, it won’t help.
Simethicone works regardless of the cause. Whether your gas came from swallowing air, dairy, beans, or carbonated drinks, simethicone will still help you feel better. Enzymes only work if the problem matches their target.
What the Experts Say
Doctors agree: simethicone is safe and effective for symptom relief. The National Institute of Diabetes and Digestive and Kidney Diseases (NIDDK) gives it a top rating. Mayo Clinic calls it the gold standard.
But they’re clear about its limits. It doesn’t reduce gas volume - just makes it easier to get rid of. That’s why some people say, “It doesn’t work for me.” They’re expecting it to stop gas from forming. It can’t.
Enzymes get a more cautious thumbs-up. Lactase is strongly recommended for confirmed lactose intolerance. Alpha-galactosidase? Only conditionally recommended. Why? Because it doesn’t work for everyone. A 2022 study found simethicone didn’t help IBS patients with chronic bloating - suggesting it’s not a fix for underlying gut issues.
Real People, Real Results
Amazon reviews tell the real story. Gas-X has over 18,000 ratings and a 4.5-star average. Most 5-star reviews say things like “instant relief” and “works when nothing else does.” But the 1-star reviews? They say, “I took it after eating beans and still felt awful.” That’s not a failure - it’s a misunderstanding. Simethicone doesn’t stop beans from making gas. It just helps you pass it easier.
Beano has 6,800 reviews and a 4.2-star rating. People who love it say, “I can finally eat chili without paying for it later.” Those who hate it say, “I took it before beans and still exploded.” Again, it’s not magic. Some people’s guts just don’t respond well to alpha-galactosidase.
One Reddit user summed it up perfectly: “Simethicone is my emergency button. Beano is my pre-game plan. I use them together.” That’s the smartest approach.
Price, Availability, and Practical Tips
Simethicone is cheap. A 200-count bottle of Gas-X costs around $12.50. Enzymes? Beano runs $19 for 100 tablets. Lactaid is similar. You’re paying more for enzymes because they’re more complex to produce.
Here’s how to use them right:
- If you feel bloated - take simethicone. Chewable tablets need to be chewed. Softgels go down like any pill.
- If you’re about to eat dairy - take lactase right before.
- If you’re eating beans, broccoli, or lentils - take Beano 5 to 10 minutes before.
- Don’t take enzymes after eating. They’re useless then.
- Don’t expect simethicone to prevent gas. It’s for after.
Combination products like Gas-Zyme (simethicone + alpha-galactosidase) are growing in popularity. They’re convenient if you’re unsure what’s causing your gas - but they cost more.
What’s Next in Gas Relief?
Companies are working on better versions. One new simethicone formulation in clinical trials could last up to 8 hours instead of 2-3. That’s a big deal for people who suffer all day.
Personalized medicine is coming too. Companies like Viome now offer gut microbiome tests that recommend specific enzymes based on your unique digestion profile. It’s expensive, but for chronic sufferers, it might be worth it.
Still, the best long-term fix isn’t a pill. It’s adjusting what you eat. Cutting back on gas-producing foods, eating slower, avoiding carbonated drinks, and managing stress all help more than any OTC product. But sometimes, you need a quick fix - and that’s where these remedies shine.
When to See a Doctor
OTC remedies are great for occasional gas. But if you’re bloated all the time, have pain, weight loss, diarrhea, or constipation, see a doctor. These could be signs of IBS, SIBO, celiac disease, or other conditions that need real treatment - not just bubble-popping.
Can I take simethicone every day?
Yes, simethicone is safe for daily use if needed. The maximum daily dose is 500 mg. Most people take 40-125 mg after meals or when symptoms appear. It doesn’t build up in your system or cause dependency. But if you’re using it daily for more than a few weeks, it’s worth checking with a doctor to find the root cause of your gas.
Do enzyme supplements really work for everyone?
No. Lactase works well for most people with lactose intolerance - about 85% see results. But alpha-galactosidase (Beano) only works for 45-78% of people, depending on their gut bacteria and the food. Some foods, like onions or artificial sweeteners, still cause gas even with Beano. It’s not a guarantee - just a helpful tool for known triggers.
Can I take simethicone and Beano together?
Yes, and many people do. Take Beano before eating beans or cruciferous vegetables to prevent gas. Then take simethicone later if you still feel bloated. They work on different parts of the problem and don’t interfere with each other. Some combination products even include both.
Is simethicone safe for kids and babies?
Yes. Mylicon infant drops (20 mg/mL) are specifically made for babies with colic or gas. The dose is usually 0.3 mL per feeding, up to 12 times a day. Simethicone doesn’t enter the bloodstream, so it’s safe for newborns. Always follow the label or your pediatrician’s advice.
Why does simethicone sometimes not work for me?
It’s not that it doesn’t work - it’s that you might be expecting the wrong thing. Simethicone doesn’t stop gas from forming. If you’re eating a lot of gas-producing foods, you’ll still make gas. Simethicone just helps you get rid of it faster. If you’re still bloated, you may need to reduce trigger foods, eat slower, or rule out an underlying condition like IBS or SIBO.
Are there natural alternatives to OTC gas remedies?
Yes. Peppermint tea, ginger, chamomile, and fennel seeds can help relax the gut and ease bloating. Probiotics may improve digestion over time. Eating slowly, avoiding chewing gum, and cutting back on carbonated drinks also reduce gas. But these work slowly. For sudden relief, OTC options are faster and more reliable.
Final Takeaway
Gas and bloating are common. You don’t need to suffer through them. Simethicone gives you fast, safe relief when you need it. Enzymes help you avoid gas before it starts - if you know your triggers. Use them together. Understand their limits. And if you’re relying on them daily, look deeper. Sometimes, the real fix isn’t in a bottle - it’s on your plate.

Simethicone is just a placebo with a fancy name. It doesn't reduce gas volume, just makes you feel like it did. I've taken it after every meal for months and still wake up looking like I swallowed a beach ball. If you're relying on this stuff daily, you're ignoring the real problem: your diet.
