What to drink to detox your stomach?

What to drink to detox your stomach is one of the most searched health questions online, and for good reason. Bloating, sluggish digestion and that heavy feeling after meals affect millions of people every single day. But here is the truth most “detox” products won’t tell you. Your body already detoxes itself. Your liver, kidneys and gut do this work around the clock without any special juice or $50 AUD powder.

That said, certain drinks genuinely support your digestive system and help it run smoother. The research backs them up. So instead of wasting money on overpriced detox teas with zero evidence behind them, focus on the drinks that actually do something for your stomach.

Let’s break down what works, what doesn’t and what the science says.

Does Your Stomach Actually Need a “Detox”?

No. Your body does not need a commercial detox product to clean itself out.

The National Center for Complementary and Integrative Health (NCCIH) states there is limited clinical evidence supporting detox or cleansing products. The FDA and FTC have even taken action against companies selling detox products because they contained hidden ingredients, made false health claims or posed safety risks.

A 2015 review published in the Journal of Human Nutrition and Dietetics found no convincing evidence to support detox diets for toxin elimination. Researchers at the University of Newcastle in Australia confirmed that detox programs “defy the general principles of human physiology” because the liver and kidneys already remove toxins efficiently.

So what should you drink instead? Focus on drinks that support your existing digestive processes rather than trying to “flush” or “cleanse” something that doesn’t need flushing.

What Is the Best Drink for Stomach Health?

Water. Plain water is the single best drink for your digestive system, and most people don’t get enough of it.

A 2024 systematic review published in JAMA Network Open examined randomised clinical trials on daily water intake and found that proper hydration supports digestion, nutrient absorption and waste elimination. Water helps break down food so your body can absorb nutrients and it keeps fibre moving through your gut to prevent constipation.

Johns Hopkins University research confirmed that increasing water intake can reduce body weight by boosting thermogenesis, reducing food intake and increasing fat oxidation. Adults in the US who were inadequately hydrated showed a significant association with obesity.

Aim for around 2 to 3 litres of water per day. If you struggle with plain water, add slices of lemon, cucumber or mint for flavour. These additions taste great and the extra hydration is what does the heavy lifting for your stomach.

Does Ginger Tea Help Your Stomach?

Yes. Ginger is one of the most well-researched natural ingredients for digestive health.

A systematic review published in Food Science and Nutrition examined clinical trials on ginger and gastrointestinal disorders. The researchers found that ginger has a carminative effect, meaning it reduces gas and bloating. It also decreases pressure on the lower oesophageal sphincter, reduces intestinal cramping and prevents dyspepsia and flatulence.

Harvard Health reports that gingerol, the main bioactive compound in ginger, speeds up the rate food exits the stomach and moves through the digestive process. This is called gastric motility and it stops food from sitting in your gut too long, which causes that uncomfortable bloated feeling.

A comprehensive review of 109 randomised controlled trials published in the journal Nutrients found ginger effective for nausea relief, improved digestive function and anti-inflammatory effects. The review confirmed ginger works through multiple pathways including 5-HT3 receptor antagonism and modulation of gastrointestinal motility.

A 2024 review in ScienceDirect confirmed that a daily dose of around 2000 mg of ginger (about a thumb-sized piece of fresh root) reduces inflammation, dyspepsia and discomfort in the digestive tract.

How to make it. Peel and slice a thumb-sized piece of fresh ginger root. Steep it in boiling water for 10 minutes. Drink it after meals for the best results. You can add a squeeze of lemon if you like. This costs almost nothing compared to commercial detox products which can run $30 to $60 AUD per box.

Is Lemon Water Good for Digestion?

Yes. Lemon water supports digestion in a few simple ways.

Lemons are high in vitamin C, a potent antioxidant that can reduce gut inflammation and support your immune system. About 75% of your immune system lives in your gut, so keeping inflammation low helps everything run better.

Lemons also contain pectin, a type of soluble fibre that acts as a prebiotic. Prebiotics feed the good bacteria in your gut and promote healthy bacterial growth. Research has shown that fibres like pectin stimulate the growth of beneficial probiotics including bifidobacterium in the gut microbiome.

The real benefit of lemon water is simple though. It gets you to drink more water. And more water means better digestion. A warm glass of lemon water first thing in the morning kickstarts hydration after 7 to 8 hours of sleep with no fluid intake.

One tip most people miss. Use the whole lemon, including the pulp. The pectin fibre and phytonutrients are concentrated in the pulp, not just the juice. Squeeze half a lemon into warm (not boiling) water and stir in some of the pulp.

Does Apple Cider Vinegar Help Your Gut?

It might, but the evidence is not as strong as social media suggests.

Apple cider vinegar (ACV) contains acetic acid, B vitamins and polyphenols. Raw, unfiltered ACV also contains “the mother,” which is a combination of proteins, enzymes and beneficial bacteria formed during fermentation.

Research from the University of Chicago Medicine confirms that ACV has mild antimicrobial properties. A 2005 study found that vinegar and lemon juice reduced Salmonella growth on salad greens, with the combination decreasing bacteria to undetectable levels.

A study published in JAMA also found that taking vinegar before a high-carb meal slowed gastric emptying and improved feelings of fullness. Another study showed that people who consumed 30 ml of ACV daily for 12 weeks saw reductions in body weight, BMI, appetite and visceral fat.

A study published in the journal eFood examined the effects of vinegar on gut microbiome composition and found it supported beneficial bacteria growth, increased immunoglobulin levels and reduced intestinal inflammation in animal models.

Here is the catch. Most of these studies are small. The University of Chicago Medicine notes that we need larger studies to truly understand ACV’s health benefits. And drinking it undiluted damages tooth enamel and can irritate your throat.

If you want to try it, mix 1 to 2 tablespoons of raw, unfiltered ACV into a glass of water. Drink it before meals. Use a straw to protect your teeth and rinse your mouth with plain water afterwards. A bottle of Bragg’s ACV costs around $8 to $12 AUD at most supermarkets.

Can Peppermint Tea Settle Your Stomach?

Yes, and it works fast.

The active ingredient in peppermint is menthol, which has an antispasmodic effect on the smooth muscles of your digestive tract. It relaxes your stomach and intestinal muscles, which relieves cramping and spasms and helps trapped gas pass more easily.

A 2014 review of 9 studies involving 726 people with irritable bowel syndrome (IBS) found that peppermint oil provided significantly better symptom relief than a placebo. Another study of 72 people with IBS showed peppermint oil capsules reduced symptoms by 40% after 4 weeks, compared to just 24.3% with a placebo.

A review of 14 clinical trials covering nearly 2000 children found peppermint reduced the frequency, length and severity of abdominal pain.

UCHealth dietitian Cara Marrs confirmed that 2 to 3 drops of peppermint oil in water after meals helps with digestion and decreases gas and belching. Multiple studies support its use as an antispasmodic for IBS.

Peppermint tea is the easiest way to get these benefits. Steep fresh or dried peppermint leaves in boiling water for 5 to 10 minutes. Drink it after meals. One to three cups per day is a safe and effective amount.

One warning. If you have acid reflux or GERD, skip peppermint. It relaxes the lower oesophageal sphincter, which can make reflux worse.

Does Green Tea Actually Boost Digestion?

Green tea supports gut health, but not in the way most detox brands claim.

Research shows green tea promotes the growth of beneficial gut bacteria while inhibiting harmful bacteria like H. pylori, which is linked to stomach ulcers. The polyphenols in green tea act as antioxidants and anti-inflammatory compounds that protect your digestive lining.

Cleveland Clinic calls green tea “the official drink of superfoods” based on a medical literature review showing benefits for heart disease, blood pressure and other health concerns.

However, a 2021 systematic review found that 3 out of 4 studies showed no acute metabolic effect from green tea. One study found a 79 calorie increase in daily energy expenditure, but it only had 10 subjects and lasted 24 hours. Two studies on green tea and long-term fat loss found no benefit.

So green tea is good for your gut health overall but it won’t “detox” anything or supercharge your metabolism. Drink it because it supports your gut bacteria and contains beneficial antioxidants. Don’t drink it expecting it to melt fat or flush toxins.

Keep it to 2 to 3 cups per day. Too much green tea is linked to sleep disturbance, constipation and in extreme cases liver issues.

What About Bone Broth for Gut Health?

Bone broth contains amino acids like glutamine, glycine and proline that support the gut lining. Glutamine in particular fuels the cells that line your intestines and helps maintain the intestinal barrier.

Research published in the journal Nutrients found that glutamine supplementation reduced intestinal permeability (sometimes called “leaky gut”) in athletes and people under physical stress.

Bone broth also provides collagen, gelatin and minerals in a form that is easy for your body to absorb. The gelatin in bone broth attracts and holds liquids, which supports healthy digestion by helping food move through your gut smoothly.

Making bone broth at home is cheap. Buy beef or chicken bones from your local butcher for around $3 to $8 AUD per kilogram. Simmer them in water with a splash of apple cider vinegar (to draw out the minerals) for 12 to 24 hours. Store bought bone broth runs about $6 to $12 AUD per litre.

What Drinks Should You Avoid for Stomach Health?

Some drinks actively harm your digestive system.

1. Alcohol irritates the stomach lining, disrupts your gut microbiome and increases intestinal permeability. Even moderate drinking affects your gut bacteria balance.
   
2. Sugary drinks and fruit juices spike blood sugar and feed harmful gut bacteria. A 2009 study found that fructose-sweetened drinks significantly increased visceral belly fat after 10 weeks compared to glucose-sweetened drinks. The fructose group also showed worsened insulin sensitivity.
   
3. Carbonated soft drinks pump your gut full of gas, which causes bloating and discomfort. As one gastroenterologist put it, carbonated drinks fill you with the very gas you are trying to get rid of.
   
4. Excessive coffee on an empty stomach stimulates stomach acid production, which can lead to heartburn and irritation in sensitive individuals. One to two cups per day with food is fine for most people.
   
5. Commercial detox teas and juices. The British Dietetic Association has stated that detox diets are “irrational and unscientific.” Most commercial detox products have no clinical evidence supporting their effectiveness. The global detox drink market hit $5.85 billion USD in 2024, which tells you how much money is being made from products that mostly don’t work.
   

What Is a Simple Daily Drink Routine for Better Digestion?

Here is a research-backed daily routine that costs almost nothing.

1. Morning. Warm water with half a lemon (including pulp) as soon as you wake up. This rehydrates you and stimulates digestive enzyme production.
   
2. With meals. Plain water. Aim for a glass with each meal to support food breakdown and nutrient absorption. If you want to try ACV, add 1 tablespoon to water before your largest meal.
   
3. After meals. Ginger tea or peppermint tea. Both support gastric motility and reduce bloating and gas. Pick whichever flavour you prefer.
   
4. Between meals. Water and green tea. Stay hydrated throughout the day and get the gut-supporting polyphenols from green tea.
   
5. Evening. Chamomile tea if you want something calming before bed. Chamomile contains apigenin, a compound with anti-inflammatory properties that soothes the digestive tract. Studies show it can reduce inflammation markers associated with conditions like ulcerative colitis.
   

This entire routine costs under $15 AUD per week. Compare that to commercial detox programs that charge $50 to $150 AUD for a few days worth of juice or supplements with limited evidence behind them.

FAQ

1. How long does it take for detox drinks to work? There is no set timeline because true “detox” drinks don’t exist. Your liver and kidneys detox your body continuously. Drinks like ginger tea and lemon water support digestion and you can feel improvements in bloating and comfort within a few days of consistent use.

2. Can I drink apple cider vinegar every day? Yes, in small amounts. Stick to 1 to 2 tablespoons diluted in water per day. Always dilute it and use a straw. Drinking it straight damages tooth enamel and can irritate your oesophagus.

3. Is warm or cold water better for digestion? Warm water is generally better because it helps dissolve food and supports blood flow to the digestive tract. Cold water can slow digestion slightly, though the difference is small. Drink whatever temperature gets you to drink more water overall.

4. Are juice cleanses good for your stomach? No. Juice cleanses strip out the fibre from fruits and vegetables, which is the part that actually supports digestion. A 2017 review found detox diets lead to weight regain once normal eating resumes. Eating whole fruits and vegetables gives you the fibre, vitamins and minerals your gut needs.

5. How much water should I drink for good digestion? Aim for 2 to 3 litres per day. Research shows that drinking 250 to 500 ml of water 30 minutes before meals led to significant reductions in body weight, BMI and waist circumference over 8 weeks.

6. Can peppermint tea make acid reflux worse? Yes. Peppermint relaxes the lower oesophageal sphincter, which can allow stomach acid to flow back up. If you have GERD or frequent heartburn, choose ginger tea or chamomile tea instead.

7. What is the cheapest way to support gut health with drinks? Water, lemon water, homemade ginger tea and homemade bone broth. All of these cost under $15 AUD per week combined and have more research behind them than any commercial detox product.

8. Do detox teas actually remove toxins? No. A review from the University of Newcastle in Australia found that detox products “defy the general principles of human physiology.” Your liver and kidneys handle toxin removal. No tea or supplement speeds this process up in a healthy person.

9. Is bone broth good for a sensitive stomach? Yes. The gelatin and amino acids in bone broth support the gut lining and are easy to digest. Glutamine in particular helps repair the intestinal barrier. Start with small amounts and see how your stomach responds.

10. Should I take probiotics instead of detox drinks? Probiotics and gut-supporting drinks serve different purposes. Probiotics introduce beneficial bacteria directly, while drinks like ginger tea and lemon water support the environment those bacteria live in. For best results, combine both with a diet rich in fibre from whole foods.

Supporting digestive health through strategic beverage choices can complement your broader wellness and fitness objectives while promoting comfortable training sessions. While implementing advanced hydration strategies for optimal cellular function provides the foundation, it’s also important to consider how your alcohol intake might be compromising your digestive and liver health.
