Learn how supplements like probiotics, magnesium, and L-glutamine can ease bloating, improve gut health, and help you feel lighter—backed by clinical research.
A Quick Note Before We Dive In:
Before reaching for supplements, it’s important to focus on the foundation: dietary and lifestyle changes. Supplements can be helpful tools, but they work best when paired with daily habits like balanced nutrition, mindful eating, regular movement, proper hydration, and stress management. It can also get pretty expensive to rely on supplementation instead of prioritize nutrition through whole foods. If those basics aren’t dialed in, even the best supplement won’t do much. Think of supplements as supportive add-ons—not replacements. They work well with your dietary and lifestyle changes, but they do not cure or replace good nutrition and movement. Here are some dietary and lifestyle changes to consider before supplementation:
- Eat balanced high protein and high fiber meals: atleast 0.8-1 g of protein per pound of lean body mass per day and 15 g of fiber per 1000 calories per day. Read this article I wrote on how to increase you protein and fiber intake.
- Identify food intolerances: pay attention to foods that trigger excessive and painful bloating like dairy, gluten, eggs, cruciferous vegetables, etc.
- Hydration: drink at least half your body weight in water a day and more for exercising or breastfeeding
- Limit alcohol: 1-2 drinks a week, even better if you can remove it entirely and have just once every great while. Alcohol is such a culprit for bloating and gut irritation.
- Daily movement: exercise and walking help gas and food move through your body.
If you feel like you’re constantly bloated, you’re not alone.
The most common question I am asked as a women’s coach is how to get rid of the lower belly “pooch”, “fupa”, or just general bloating. Whether it’s after meals, around your cycle, or randomly during the day, bloating can feel frustrating, heavy, and uncomfortable. The good news? There are evidence-backed supplements that can actually help—when you know what your body needs.
In this post, we’re breaking down the 7 best supplements for bloating, how they work, who they’re for, and what the research says.
1. Probiotics
What they do: Support a balanced gut microbiome to improve digestion and reduce gas, bloating, and inflammation.
Best strains:
- Bifidobacterium infantis 35624
- Lactobacillus plantarum Lp299v
When to take it: First thing in the morning on an empty stomach or 30 minutes before a meal.
What the research says: A meta-analysis of 46 clinical trials showed that specific probiotic strains significantly reduced bloating and other IBS-related symptoms.
Best for: Ongoing bloating, irregular bowel movements, or post-antibiotic gut issues.
2. L-Glutamine
What it does: Strengthens the gut lining and reduces inflammation, especially useful in cases of leaky gut or IBS.
How to take it: Powder or capsules; 5-10g daily on an empty stomach.
When to take it: First thing in the morning and/or between meals.
What the research says: A meta-analysis with 352 participants found that high-dose glutamine supplementation significantly improved intestinal permeability.
Best for: Chronic bloat, food sensitivities, gut healing.
3. Magnesium Citrate or Glycinate
What it does: Supports regular bowel movements and relaxes the GI tract.
Why it helps: Constipation is a major cause of bloating. Magnesium helps draw water into the bowels and stimulate motility.
When to take it: In the evening, about 1–2 hours before bed, to support overnight digestion and sleep.
What the research says: Widely used as a safe laxative; studies support its role in relieving bloating related to constipation.
Best for: PMS-related bloat or sluggish digestion.
4. Digestive Enzymes
What they do: Help break down carbs, fats, and proteins so your body can better digest food with less gas and discomfort.
What to look for: Multi-enzyme blends that include amylase, lipase, protease, lactase, cellulase, and ox bile.
When to take it: Right before or with meals.
What the research says: A placebo-controlled study showed that digestive enzymes reduced post-meal bloating and improved comfort in healthy adults.
Best for: Bloating right after eating, undigested food in stool.
5. Peppermint Oil (Enteric-Coated)
What it does: Relaxes the muscles of the digestive tract and reduces gas buildup.
When to take it: 30–60 minutes before meals, up to 3x per day.
What the research says: Clinical trials show peppermint oil significantly reduces IBS symptoms, including bloating and cramping.
Best for: Gas, spasms, or bloating tied to IBS.
Note: Look for enteric-coated capsules to avoid reflux.
6. DIM (Diindolylmethane)
What it does: Supports estrogen metabolism and may relieve hormonal bloating.
How it works: DIM helps shift estrogen down a “healthier” pathway (2-OH), which may reduce water retention and inflammation during the menstrual cycle.
When to take it: With food in the morning to support metabolism and minimize nausea.
What the research says: Small studies show DIM can reduce estrogen dominance symptoms, but large-scale studies on bloating are limited.
Best for: Cyclical bloating tied to PMS, tender breasts, or mood swings.
Caution: Not for everyone. Avoid long-term use without guidance.
7. Activated Charcoal
What it does: Binds to gas and toxins in the digestive tract, helping relieve sudden bloating or discomfort.
When to use it: Occasionally, after a heavy meal or trigger foods.
When to take it: 1 hour before or 2 hours after meals, and away from medications or supplements.
What the research says: Clinical research supports its use in reducing intestinal gas and abdominal cramps.
Best for: Emergency bloat relief, not daily use.
Final Thoughts: Supplements Are Tools, Not Magic Fixes
While supplements can provide noticeable relief, they work best when paired with gut-supportive habits like:
- Chewing food thoroughly
- Avoiding overeating
- Managing stress
- Identifying food intolerances
If bloating is affecting your day-to-day life, these tools can help you start feeling more like yourself—lighter, more comfortable, and more confident.
