TikTok has become the go-to place for the latest trends—from dance challenges to DIY skincare. But lately, it’s also turned into a massive (and unregulated) wellness lab, especially when it comes to digestion. If you’ve ever scrolled past someone claiming they “healed their gut in 7 days” with a homemade concoction, you’re not alone. TikTok gut health hacks rack up millions of views—but not all of them are backed by science. Before you jump into fermented smoothies or baking soda shots, let’s break down which hacks are legit and which could seriously backfire.
1. Drinking Celery Juice Every Morning – Mostly Hype

Celery juice is one of the biggest gut health crazes on TikTok, with influencers claiming it cures everything from bloating to brain fog. While celery is a great source of antioxidants and fiber, juicing it removes most of that fiber, leaving behind a mostly watery drink. There’s no solid scientific evidence that drinking celery juice alone “heals the gut.” For some people, especially those with IBS, it could even cause cramping or diarrhea. If you love it, enjoy it—but don’t expect it to be a miracle cure.
2. Taking Apple Cider Vinegar Shots – Can Be Harmful
Apple cider vinegar (ACV) is another popular staple in TikTok gut health hacks, often promoted as a natural way to improve digestion and metabolism. But straight-up vinegar can erode tooth enamel, irritate your esophagus, and upset your stomach when taken undiluted. While small, diluted amounts may offer minor benefits, there’s no need to chug it. Registered dietitians recommend caution, especially if you have acid reflux or stomach sensitivity. A better approach? Mix a teaspoon with water and sip slowly, if at all.
3. Eating Probiotic-Rich Fermented Foods – Legit with Limits
Unlike some other trends, eating fermented foods like kimchi, sauerkraut, kefir, and plain yogurt can support gut health. These foods contain natural probiotics that help feed the good bacteria in your digestive system. However, not all fermented foods are created equal—shelf-stable items may be pasteurized, killing those helpful microbes. Also, loading up too quickly can cause bloating if your gut isn’t used to it. This is one of the TikTok gut health hacks that’s legit—just ease into it and watch how your body responds.
4. “Gut Health Smoothies” With 10+ Ingredients – Not Always Safe
TikTok is full of flashy gut-healing smoothie recipes made with everything from chia seeds to aloe juice to digestive enzymes. While some ingredients are beneficial, the combinations are often excessive and unnecessary. Dumping ten “superfoods” into a blender can overwhelm your digestive system rather than support it. Plus, not all bodies react well to high-fiber smoothies, especially on an empty stomach. Keep it simple: 2–3 gut-friendly ingredients are more than enough.
5. Taking Digestive Enzyme Supplements Without Diagnosis – Risky
Digestive enzymes are gaining traction as the new “must-have” supplement in the TikTok wellness space. But unless you have a diagnosed enzyme deficiency (like lactose intolerance or EPI), you probably don’t need them. Overuse can disrupt your body’s natural digestive process and cause side effects like cramping or diarrhea. Worse, it can mask underlying issues that need professional treatment. Always consult a healthcare provider before jumping into enzyme supplements.
6. Eating a Fiber-Rich Diet – Absolutely Effective
This one isn’t new, but it’s finally getting the attention it deserves. Fiber helps regulate bowel movements, feeds beneficial gut bacteria, and keeps your digestive system humming. Many TikTokers promote high-fiber foods like oats, beans, and chia seeds to help reduce bloating and support long-term gut health. The trick is adding fiber gradually and drinking plenty of water to avoid discomfort. Of all the TikTok gut health hacks, this one is tried, true, and well-supported by science.
7. Drinking Chlorophyll Water – More Trend Than Treatment

Chlorophyll water went viral for supposedly detoxing the body and supporting digestion. While chlorophyll does have some antioxidant properties, there’s very little research linking it directly to improved gut health. Most of the “benefits” shared online are anecdotal at best. Plus, concentrated liquid chlorophyll can cause digestive upset in large doses. If you enjoy the flavor and feel good drinking it, go ahead—but don’t rely on it for serious digestive support.
8. “Gut Healing Detoxes” – Just Don’t
One of the most dangerous TikTok gut health hacks is the so-called “detox cleanse.” These often involve fasting, juice-only days, or harsh laxatives that promise to reset your gut in a few days. In reality, your body already has a liver and kidneys that do the detoxing for you. These cleanses can disrupt your natural gut bacteria, lead to dehydration, and harm your metabolism. If a hack sounds too good to be true, it probably is.
When It Comes to Gut Health, Trends Aren’t a Shortcut
Everyone wants better digestion, less bloating, and more energy, but TikTok isn’t a substitute for real science or personalized care. While a few of these TikTok gut health hacks have solid foundations, many are exaggerated or even risky. Gut health isn’t about quick fixes—it’s about consistent habits like eating whole foods, managing stress, sleeping well, and staying hydrated. Before you try what a 20-second clip tells you, ask: Is this helping or hyping?
