What does my IBS feel like most days?

Bloating, gas, and bathroom habits I can't predict

Probiotics
Supported by controlled trials· Recognised traditional use (Evidence grade A · Traditional use recognised)Recognised traditional use
Supports gut microbiome balance for IBS symptoms
Why this matches
If your digestion feels unpredictable with bloating and gas, a general probiotic supports the gut microbiome that sits at the center of IBS.
Why try it
A large systematic review and meta-analysis of randomized trials found probiotics modestly improved IBS symptom severity compared with placebo, though the certainty of the evidence is low and effects vary by product and strain.
Dose or use
Follow product labeling for a consistent daily dose over several weeks; consult a healthcare practitioner.
Time to results
Typically 4–8 weeks
Key study
Systematic review and meta-analysis (2026, PMID 41820241) of 40 RCTs found probiotics significantly improved IBS symptom-severity scores versus placebo, but GRADE-rated certainty was low and quality-of-life gains were not statistically significant, so benefits vary by product and strain.
Caution
May cause temporary gas or bloating when starting; ease in gradually.
Partially hydrolyzed guar gum
Limited human trials so far· Most of the research is laboratory or animal work (Evidence grade C · No traditional record)
Gentle fiber that supports bowel regularity
Why this matches
For unpredictable digestion and bloating, this gentle soluble fiber has preliminary clinical support as a gut-friendly way to add fiber in IBS.
Why try it
An open-label randomized multicenter trial suggests fiber supplementation, including partially hydrolyzed guar gum, may improve IBS symptoms and bowel habits.
Dose or use
Follow product labeling; consult a healthcare practitioner.
Time to results
Typically 2–4 weeks
Key study
Open-label randomized multicenter trial (2002, PMID 12184518) compared a wheat bran diet with partially hydrolyzed guar gum (PHGG) in IBS patients; unblinded design with subjective symptom endpoints, so results are preliminary.
Caution
Increase fiber intake gradually and drink plenty of water to avoid initial gas.
Berberine
Centuries of traditional use across more than one tradition· Human evidence not yet assessed (Evidence grade not assigned · Traditional use classical)Classical use across multiple traditions
Traditionally used for digestive and bowel upset
Why this matches
If cramping and irregular bowel habits are your main complaint, berberine has a long traditional use for gut discomfort and loose stools.
Why try it
Traditionally used to support gut microbiome balance and ease digestive upset.
Dose or use
Follow product labeling; consult a healthcare practitioner.
Time to results
Typically 2–6 weeks
Key study
Traditionally used for this condition; this specific use has not been confirmed in controlled clinical trials.
Caution
May interact with certain medications; avoid in pregnancy. Consult your practitioner.
Fiber Deficiency
Centuries of traditional use· Human evidence not yet assessed (Evidence grade not assigned · Traditional use long-standing)Long-standing traditional staple
Low dietary fiber can drive IBS irregularity
Why this matches
If you feel run-down and want to check the basics, a quick look at your fiber intake is worthwhile — too little is a common, correctable driver of constipation and bloating.
Why try it
Reviewing your diet for adequate fiber is a simple root-cause check; low fiber commonly contributes to constipation, irregularity and bloating in IBS.
Dose or use
Review your typical diet with a practitioner or dietitian; increase fiber gradually from food.
Time to results
Bowel habits often improve over 2–4 weeks
Key study
Identifying and correcting a shortfall in dietary fiber is a root-cause check, not a treatment claim — review your intake with your provider.
Caution
Increase fiber slowly with plenty of water; too much too fast can worsen gas and bloating.

Painful cramps and spasms are my biggest problem

Peppermint Oil
Supported by controlled trials· Centuries of traditional use (Evidence grade A · Traditional use long-standing)Long-standing traditional staple
Antispasmodic that eases cramping and bloating
Why this matches
When bloating and unpredictable cramping are your main problem, enteric-coated peppermint oil relaxes the gut muscle to ease that spasm-type discomfort.
Why try it
A systematic review and meta-analysis of 10 randomized controlled trials found enteric-coated peppermint oil eased overall IBS symptoms and abdominal pain better than placebo, though the overall quality of evidence was low.
Dose or use
Enteric-coated capsules taken before meals per product labeling; consult a healthcare practitioner.
Time to results
Typically 2–4 weeks
Key study
Systematic review and meta-analysis (2022, PMID 35942669) of 10 RCTs (1,030 patients) found peppermint oil superior to placebo for global IBS symptoms (NNT 4) and abdominal pain; however, evidence quality was rated very low and mild side effects such as reflux were more common than with placebo.
Caution
Can trigger heartburn or reflux; the enteric coating helps. Avoid if you have significant GERD.
ST25 (Tianshu) - Stomach 25
Centuries of traditional use· Human evidence not yet assessed (Evidence grade not assigned · Traditional use long-standing)Long-standing traditional staple
Abdominal acupressure point for cramps and bloating

Stress and anxiety clearly set off my flares

Hypnotherapy
Supported by controlled trials (Evidence grade A · No traditional record)
Calms the gut-brain stress response
Why this matches
If stress and anxiety are driving your flares, gut-directed hypnotherapy is designed to address the gut-brain connection that can amplify IBS symptoms.
Why try it
A systematic review and meta-analysis of mostly small trials suggests gut-directed hypnotherapy may reduce IBS symptom severity.
Dose or use
Typically a course of weekly sessions with a practitioner trained in gut-directed hypnotherapy.
Time to results
Typically 4–12 weeks of sessions
Key study
Systematic review and meta-analysis (2026, PMID 41401051) of hypnotherapy trials in IBS suggests a possible reduction in symptom severity; component trials were small and could not be blinded, so certainty is moderate at best.
Caution
Seek a practitioner trained in gut-directed hypnotherapy.

I feel run-down and want to check if something basic is off

Vitamin D
Limited human trials so far· Most of the research is laboratory or animal work (Evidence grade C · No traditional record)
May help IBS symptoms, mainly if your level is low
Why this matches
If you suspect something basic is off, checking your vitamin D is a sensible step — it is most likely to help IBS symptoms and quality of life when your level is actually low.
Why try it
A meta-analysis of mostly small, mixed-quality trials suggests vitamin D may modestly improve IBS symptom severity and quality of life, with the clearest signal in people who are deficient.
Dose or use
1,000–2,000 IU daily with food; confirm your level with a healthcare practitioner.
Time to results
Typically 6–12 weeks
Key study
Systematic review and meta-analysis (2025, PMID 39235428) of mostly small, mixed-quality trials found a possible benefit of vitamin D on IBS symptom severity and quality of life, strongest when baseline levels were low.
Caution
High-dose supplementation warrants medical supervision, especially with kidney conditions.

Vitamin D Deficiency
Centuries of traditional use· Human evidence not yet assessed (Evidence grade not assigned · Traditional use long-standing)Long-standing traditional staple
Low vitamin D may worsen gut symptoms
Why this matches
If you feel run-down and want to check what's going on underneath, confirming your vitamin D level is a practical first step.
Why try it
If you're low in vitamin D, correcting the deficiency may help support overall gut and immune function.
Dose or use
Ask your healthcare practitioner for a simple blood test to check your level.
Time to results
Results vary based on starting levels
Key study
Correcting a documented shortfall can support recovery; this is a root-cause check, not a treatment claim — ask your provider to test your levels.
Caution
Do not self-dose high amounts without knowing your current level.
