Top 10 Best Peppermint Oil Capsules for IBS (2026)
01 · Best overall / clinical IBS✓ Label verified · Supplement Facts read Sep 7, 2026Best overall / clinical IBS: IBgard Peppermint Oil Capsules, 48ct
The most-studied IBS-specific peppermint oil — patented Site-Specific Targeting (SST) microspheres deliver ultra-purified oil to the small intestine, fast relief without the stomach release that causes heartburn.
$30 / month$1.25 / 2-capsule SST serving
Why it wins: all five scores, pros & cons, full label
- The exact formulation studied in Cash 2016 — 40% reduction in Total IBS Symptom Score at 4 weeks, with relief beginning as early as 24 hours
- SST microsphere technology spreads ultra-purified oil across the small intestine rather than dumping it, which targets the antispasmodic effect and minimizes the LES-relaxation that causes heartburn
- 180 mg peppermint oil per 2-capsule serving lands squarely in the clinical dose range
- The #1 gastroenterologist-recommended brand among GIs who recommend peppermint oil — the trust signal in this category
- Most expensive per dose on the list — the SST technology is a real premium over classic enteric softgels
- 48-capsule box runs down fast at flare dosing (2 caps, 3×/day), so monthly cost climbs during a bad stretch
- Per serving
- 180 mg peppermint oil (2 capsules, 90 mg each)
- Bottle
- 48 capsules (~12 days at flare dosing, longer for daily support)
- Testing
- Ultra-purified peppermint oil; #1 gastroenterologist-recommended peppermint brand; made under cGMP
- Form
- SST triple-coated sustained-release microspheres (ultra-purified peppermint oil)
Our take — If you want the peppermint oil with the strongest IBS-specific evidence and the lowest heartburn risk, IBgard is the pick. The SST delivery system was built specifically to solve peppermint's two problems at once — get the oil to the intestine and keep it out of the stomach — and it's the formulation behind the best modern trial in the category. You pay for it, and the small box empties quickly during a flare. But for a first serious attempt at controlling IBS pain, urgency, and bloating with peppermint, this is the most reliable place to start.

The Other 9, Ranked
02Best value / gold-standard enteric: Nature's Way Pepogest Enteric Peppermint Oil, 60ct
9.1SAC Score™The classic enteric peppermint at the exact 0.2 mL trial dose — reliable, transparent, and one of the cheapest legitimate enteric options on the shelf.
StrongestCost per effective dose10.01WeakestThird-party testing + manufacturing quality8.0- Per serving
- 0.2 mL peppermint oil (~187 mg) per softgel, up to 3×/day
- Bottle
- 60 softgels (~20 days at 3/day, longer at maintenance)
- Testing
- Nature's Way QC, cGMP-manufactured, gluten-free
All five scores, pros & cons, full label
What We Like- Delivers the exact 0.2 mL (~187 mg) enteric dose used across the classic peppermint-oil IBS trials — the textbook clinical dose, no guesswork
- Genuinely enteric-coated to survive stomach acid and release in the intestine, so it works for IBS and minimizes heartburn
- One of the lowest costs per effective dose of any real enteric peppermint on the market
- Simple single-oil formula with a clear, honest dose — easy to dial 1-3×/day to your symptoms
What You Live With- Plain softgel with no extra coat — the most reflux-sensitive users may still prefer Heather's extra-enteric version (#3)
- 60-count bottle empties in about three weeks at full 3×/day flare dosing
- Form
- Enteric-coated softgel (releases in the intestine, not the stomach)
Our take — Pepogest is the value gold standard and the smartest default for most buyers. It hits the precise 0.2 mL enteric dose the trials used, it's honestly labeled, and it costs a fraction of the engineered options — there's no cheaper way to get the clinically validated peppermint dose into your intestine intact. The only reasons to spend more are IBgard's stronger evidence and SST delivery (#1) or Heather's extra coat for severe reflux sensitivity (#2). For everyone else weighing cost against efficacy, start here.
03Best for sensitive stomachs: Heather's Tummy Tamers Peppermint Oil, 90ct
9.0SAC Score™The IBS-dietitian favorite — a high-dose enteric peppermint with 50% more enteric coating than standard plus ginger and fennel, built for people who can't tolerate peppermint in other forms.
StrongestEnteric coating9.52WeakestThird-party testing + manufacturing quality8.5- Per serving
- Peppermint oil + fennel oil + ginger oil (1 softgel, 1-3×/day)
- Bottle
- 90 softgels (~1-3 months depending on dosing)
- Testing
- Formulated specifically for IBS; designed for reflux-sensitive users
All five scores, pros & cons, full label
What We Like- Extra enteric coating (50% more than standard) makes it the most reflux-tolerant enteric option here — the pick for people who get heartburn from other peppermint
- Adds fennel and ginger, both carminatives that target gas and bloating, on top of peppermint's antispasmodic effect
- Created within an IBS-focused brand (Heather's Tummy Care) with strong dietitian and patient following
- 90-softgel bottle gives a long runway at the typical 1-3/day dose
What You Live With- Per-capsule peppermint-oil milligrams are not as transparently stated as the simple 0.2 mL enteric picks
- Combination formula means you can't isolate the peppermint dose if you only want peppermint
- Form
- Enteric-coated softgel (50% more enteric coating than industry standard)
Our take — Heather's Tummy Tamers is the sensitive-stomach answer. The signature 50%-extra enteric coat is purpose-built for the exact people peppermint oil usually fails — those who get reflux or heartburn from standard softgels — and the added fennel and ginger broaden it from a pure antispasmodic into a bloating-and-gas formula too. The trade-off is label transparency on the precise peppermint milligrams and the fact that it's a blend. If plain enteric peppermint has burned you before, this is the one to try next.
04Best bulk value: NOW Peppermint Gels with Ginger & Fennel, Enteric, 90ct
8.7SAC Score™A trusted budget brand done right — genuinely enteric-coated, a generous peppermint dose, plus gas-targeting ginger and fennel at a low cost per softgel.
StrongestCost per effective dose9.52WeakestReal-world IBS/bloating response + tolerability8.0- Per serving

- NOW in-house QC labs, GMP-certified facility, non-GMO
All five scores, pros & cons, full label
What We Like- Genuinely enteric-coated — far better for IBS than the non-enteric budget bottles at a similar price
- Generous peppermint dose per serving plus ginger and fennel for gas and bloating
- NOW's in-house QC is among the most consistent in the industry, with decades of household-brand trust
- One of the lowest costs per softgel on the entire list — excellent bulk value
What You Live With- Combination formula — you can't isolate a pure peppermint dose if that's all you want
- Standard enteric coat (not an extra coat or SST), so very reflux-sensitive users may prefer #1 or #2
- Form
- Enteric-coated softgel (releases in the intestine)
Our take — NOW Peppermint Gels are the bulk-value pick — proof that a budget brand can still get the fundamentals right. It's genuinely enteric-coated, carries a solid peppermint dose, and folds in ginger and fennel for bloating, all at one of the lowest per-softgel prices here. The only reasons to climb higher are IBgard's evidence and SST delivery, Heather's extra coat for severe sensitivity, or a desire for single-oil simplicity. For a trustworthy, enteric, gas-and-bloating-friendly peppermint at minimal cost, this is the value workhorse.
05Best peppermint + caraway combo: Regimint Peppermint Oil Plus Caraway, 60ct
8.5SAC Score™Mirrors the European clinical peppermint-caraway combination for functional dyspepsia and IBS — a genuine enteric coat plus caraway's complementary antispasmodic action.
StrongestEnteric coating9.03WeakestCost per effective dose7.5- Per serving
- 200 mg peppermint oil + 100 mg caraway oil (1 capsule, up to 3×/day)
- Bottle
- 60 capsules (~20 days at 3/day)
- Testing
- Made in USA, gluten-free, soy-free, no pork (bovine gelatin)
All five scores, pros & cons, full label
What We Like- Pairs 200 mg peppermint with 100 mg caraway oil — the same combination repeatedly studied in Europe for functional dyspepsia and IBS
- Solid 200 mg peppermint dose per capsule sits inside the clinical range on its own
- Genuinely enteric-coated to protect the oils and target release past the stomach
- Caraway adds a second antispasmodic/carminatic action, useful for overlapping dyspepsia and bloating
What You Live With- More expensive than the plain enteric softgels for a similar peppermint dose
- The peppermint-caraway combo is best matched to dyspepsia-overlap IBS; pure-IBS buyers may not need the caraway
- Form
- Enteric-coated capsule (releases past the stomach)
Our take — Regimint is the pick if your symptoms straddle IBS and functional dyspepsia (upper-gut fullness, early satiety, bloating after meals). The peppermint-caraway pairing is one of the better-studied combinations in European gastroenterology, and Regimint delivers it with a real enteric coat and a clinical-range 200 mg peppermint dose. You pay a bit more than for a single-oil softgel, and the caraway is redundant if your problem is purely lower-gut IBS — but for the dyspepsia overlap, this combination earns its place.
06Best botanical blend: Solaray Peppermint Oil, Enteric, 60ct
7.5SAC Score™A higher 250 mg peppermint dose in a genuine enteric softgel, rounded out with quercetin and supporting botanicals for gut comfort.
StrongestEnteric coating8.5WeakestReal-world IBS/bloating response + tolerability6.0- Per serving
- 250 mg peppermint oil + 100 mg quercetin + 50 mg each rosemary/thyme/chamomile oil (1 softgel)
- Bottle
- 60 softgels (1 softgel up to 2×/day)
- Testing
- Solaray in-house facility, lab-verified for potency/purity/identity
All five scores, pros & cons, full label
What We Like- Higher 250 mg peppermint dose per softgel — comfortably inside the clinical range in a single capsule
- Genuinely enteric-coated to bypass the stomach and release in the intestine
- Adds quercetin plus rosemary, thyme, and chamomile oils for supporting gut and anti-inflammatory comfort
- Solaray lab-verifies for potency, purity, and identity in its own facility
What You Live With- The supporting botanicals are not as evidence-backed for IBS as peppermint itself — you're partly paying for extras
- More moving parts in the formula means more potential for sensitivity in reactive users
- Form
- Enteric-coated softgel (targets release in the intestine)
Our take — Solaray Peppermint Oil is the botanical-blend option for buyers who want a higher single-capsule peppermint dose with some supporting herbs. The 250 mg of enteric-coated peppermint is the real engine here and it's well dosed; the quercetin and rosemary/thyme/chamomile are reasonable additions but carry far less IBS evidence than peppermint. If you like the idea of a fuller botanical formula and want a strong peppermint dose in one enteric softgel, it's a fair pick — just know the peppermint is doing the heavy lifting.
07Commission E heritage: Nature's Way Peppermint Soothe, 60ct
7.5SAC Score™The long-running Enzymatic Therapy Peppermint Plus formula, built to German Commission E botanical standards — a heritage enteric peppermint with rosemary and thyme.
StrongestEnteric coating8.5WeakestCost per effective dose6.0- Per serving
- Peppermint oil + rosemary oil + thyme oil (1 softgel, up to 3×/day)

All five scores, pros & cons, full label
What We Like- A heritage formula (the old Enzymatic Therapy Peppermint Plus) built to German Commission E botanical-medicine standards
- Genuinely enteric-coated to protect the oil through the stomach
- Adds rosemary and thyme oils for supporting digestive comfort
- Backed by Nature's Way's established manufacturing and QC
What You Live With- Per-capsule peppermint milligrams are less clearly stated than the simple 0.2 mL Pepogest softgel from the same parent brand
- Rebrand from Enzymatic Therapy to Nature's Way Peppermint Soothe can confuse buyers looking for the original
- Form
- Enteric-coated softgel (releases in the intestine)
Our take — Peppermint Soothe is the heritage pick — the well-regarded old Enzymatic Therapy Peppermint Plus, now under the Nature's Way label, formulated to German Commission E standards with rosemary and thyme alongside the peppermint. It's a genuine enteric softgel with a long track record. The catch is that its sibling, Pepogest (#3), states a cleaner 0.2 mL dose at a lower price from the same parent company — so unless you specifically want the rosemary/thyme blend or the legacy formula, Pepogest is the more transparent value. Still a solid, trustworthy enteric choice.
08Budget high-count: Carlyle Peppermint Oil, 150ct
7.1SAC Score™A budget high-count coated peppermint from a value house brand — correctly coated and very cheap per softgel, but a low 50 mg peppermint dose with added rosemary and thyme.
StrongestClinical-dose alignment + label honesty8.5WeakestEnteric coating6.5- Per serving
- 50 mg peppermint oil + rosemary oil + thyme oil (1 softgel)
- Bottle
- 150 softgels (high count; low dose, so several per clinical dose)
- Testing
- Carlyle (NaturaLife/Vitamer house brand), non-GMO, gluten-free
All five scores, pros & cons, full label
What We Like- Very high 150-count bottle at one of the lowest per-softgel prices on the list
- Coated softgel with added rosemary and thyme oils for supporting digestive comfort
- Non-GMO and gluten-free from a high-volume value house brand
- Big count gives a long runway even when taking multiple softgels per dose
What You Live With- Low 50 mg peppermint dose per softgel — like Mason, you need several to reach a clinical dose
- Coating detail is less rigorously documented than the dedicated enteric IBS brands, so it's a notch below the verified-enteric picks for IBS reliability
- Form
- Coated softgel (rosemary and thyme oils added)
Our take — Carlyle is the budget high-count pick — a coated peppermint-plus-rosemary-and-thyme softgel at a very low per-unit price, in a generous 150-count bottle. It's a reasonable cheap option, but it shares Mason's low-dose problem (50 mg means several softgels per clinical dose) and its coating is less rigorously documented than the dedicated IBS enteric brands. Fine as an inexpensive, gentle daily-comfort peppermint; for trial-grade IBS dosing with verified enteric delivery, the 0.2 mL softgels (#3) or IBgard (#1) are the surer bets.
09Budget enteric pick: Mason Natural Peppermint Oil 50mg Enteric, 90ct
6.5SAC Score™The cheapest true enteric option on the list — correctly coated to reach the intestine, but at a low 50 mg dose, so you'll likely need several softgels to hit a clinical dose.
StrongestEnteric coating8.0WeakestClinical-dose alignment + label honesty4.0- Per serving
- 50 mg peppermint oil per softgel
- Bottle
- 90 softgels (low dose — multiple softgels needed per clinical dose)
- Testing
- Mason cGMP manufacturing; gluten-free, soy-free; 50+ years in market
All five scores, pros & cons, full label
What We Like- Genuinely enteric-coated despite the rock-bottom price — it gets the one thing that matters right
- Among the cheapest peppermint bottles available, and correctly targets the intestine
- Gluten-free and soy-free, made under cGMP by a long-established brand
- Fine as a low, gentle starting dose for first-time or very sensitive users
What You Live With- At only 50 mg per softgel you need roughly 3-4 softgels to reach a single clinical (~180-200 mg) dose, which erodes the price advantage and the count
- Low per-capsule dose makes consistent therapeutic dosing more cumbersome than the 0.2 mL softgels
- Form
- Enteric-coated softgel (releases in the intestine, not the stomach)
Our take — Mason Natural is the budget enteric pick — and it deserves credit for being genuinely enteric-coated at a price where many competitors quietly aren't. The honest catch is the dose: at 50 mg per softgel, you'd need three or four to match one 0.2 mL Pepogest capsule, which means the real cost per clinical dose and the pill count are less favorable than the sticker suggests. Buy it as a gentle low-dose starter or if you want fine dose control; for efficient clinical dosing, Pepogest (#3) is the better value.
10Budget NON-enteric — form caveat: Nutricost Peppermint Oil 50mg, 120ct
4.2SAC Score™Cheap, high-count, and cleanly third-party tested — but NOT enteric-coated, which makes it weak for IBS and a common cause of heartburn. The form to avoid for gut symptoms.
StrongestThird-party testing + manufacturing quality9.02WeakestEnteric coating2.0- Per serving
- 50 mg peppermint oil per softgel
- Bottle
- 120 softgels (high count, but non-enteric)
- Testing
- Third-party tested, gluten-free, GMO-free, GMP-compliant facility
All five scores, pros & cons, full label
What We Like- Genuinely third-party tested with a clean, transparent label — Nutricost's quality control is good
- Very cheap and high-count, with a clearly stated 50 mg peppermint dose
- Fine for non-gut uses where stomach release doesn't matter (e.g. general aromatic/oral use)
- GMO-free and gluten-free from a GMP-compliant facility
What You Live With- NOT enteric-coated — it releases peppermint oil in the stomach, the single thing the whole category exists to avoid, so it works poorly for IBS
- Stomach release relaxes the esophageal valve and is a common cause of the heartburn/reflux peppermint is notorious for
- Low 50 mg dose on top of the wrong delivery makes it the weakest option here for gut symptoms
- Form
- NON-enteric softgel (releases in the stomach — the wrong place for IBS)
Our take — Nutricost Peppermint Oil is a well-made product that illustrates exactly the mistake this whole list is built to prevent. Its testing and label are genuinely good — but it is NOT enteric-coated, which means the oil releases in your stomach, where it works poorly for IBS and commonly triggers the heartburn peppermint is infamous for. For gut symptoms, delivery is the entire game, and this one delivers to the wrong place. It sits last on purpose: cheap and clean, but the wrong form. If your goal is IBS, bloating, or cramps, choose any enteric pick above instead.
Peppermint Oil In Four Short Lessons
Buy enteric-coated capsules only.
Plain peppermint oil releases in the stomach, causes reflux and heartburn, and burns off the dose before it reaches the gut. An enteric coat delivers it to the intestine intact.
Check for the trial dose.
Classic enteric softgels in the trials delivered about 0.2 mL (187 mg) of oil. The milligrams matter less than whether the capsule survives the stomach.
Use it for IBS-type cramping.
Menthol relaxes intestinal smooth muscle, and meta-analyses put peppermint oil ahead of fibre and antispasmodics for IBS symptom relief (Khanna 2014, Ford 2008).
Ranked on the file's three verified studies: Khanna 2014 (PMID 24100754), Ford 2008 (PMID 19008265, BMJ), and Cash 2016 (PMID 26319955) — full scoring in the methodology below.
Each pick was scored 0-10 across five criteria, then weighted to a final composite. Enteric coating / gut-targeted delivery carries by far the most weight because peppermint oil is the textbook case of a supplement whose label dose is meaningless if it releases in the wrong place — oil freed in the stomach relaxes the esophageal valve and causes the reflux/heartburn that peppermint is notorious for, and burns off before reaching the intestine where the antispasmodic effect lives. Clinical-dose alignment and label honesty is second: the trial-validated dose is roughly 180-225 mg of peppermint oil per capsule (the classic 0.2 mL softgel), taken up to three times daily, and we reward bottles that hit that range and clearly state their enteric claim. Third-party testing is the quality gate. Cost per effective (gut-delivered) dose is the tiebreaker, and real-world IBS/bloating response and tolerability anchor the math against the trial record.
Enteric coating / gut-targeted delivery · 40%
The gate. Gut-targeted delivery systems — IBgard's SST microspheres and genuine enteric coatings — get the top tier because each is designed to survive the stomach and release peppermint oil in the small intestine, which is both where it works and how it avoids the reflux/heartburn that plain oil causes. Standard enteric softgels score strongly; an 'extra' enteric coat for sensitive stomachs scores higher still. A NON-enteric peppermint softgel scores at the bottom — it releases in the stomach, is weak for IBS, and commonly triggers heartburn.
Clinical-dose alignment + label honesty · 25%
The trial-validated dose is roughly 180-225 mg peppermint oil per capsule — the classic 0.2 mL (~187 mg) enteric softgel — taken up to three times daily. Bottles that land in that window and clearly declare their peppermint-oil milligrams and enteric status score full marks; very low single-digit-percentage or under-dosed bottles (e.g. 50 mg) lose points because you must take several to reach a clinical dose, and any bottle vague about its coating is penalized.
Third-party testing + manufacturing quality · 15%
GMP manufacturing, third-party testing, a public COA, non-GMO/gluten-free verification, or ultra-purification of the peppermint oil. Peppermint oil quality and purity vary, and the enteric coat must actually be applied correctly to work — so manufacturing rigor is a real differentiator, not a formality.
Cost per effective dose · 12%
Monthly cost divided by the gut-delivered dose at the label serving — not raw price. A cheap non-enteric bottle that releases in the stomach is not cheap per effective dose. The classic 0.2 mL enteric softgels win this axis on value; the engineered SST and extra-coat formulations cost more but justify it on delivery and tolerability.
Real-world IBS/bloating response + tolerability · 8%
Alignment with Khanna 2014 (enteric peppermint oil superior to placebo for IBS), Ford 2008 (peppermint oil effective for IBS, ahead of fibre and antispasmodics), and Cash 2016 (IBgard SST, 40% symptom reduction at 4 weeks). Formulations that match the trial form and dose — and that add carminatives like ginger/fennel for bloating — score higher than under-dosed or non-enteric bottles.

How peppermint oil works for the gut
- 1
An antispasmodic for the gut
Menthol relaxes the smooth muscle of the intestinal wall, easing the cramping and spasm behind IBS pain and bloating. This antispasmodic action is one of the better-evidenced natural IBS tools.
- 2
Enteric coating is non-negotiable
Released in the stomach, peppermint oil causes heartburn and never reaches the target. Enteric coating carries it past the stomach to dissolve in the intestine — which is why gut-targeted delivery is our single heaviest axis.
- 3
Clinical dose
IBS trials used specific per-capsule doses over several weeks. Under-dosed or non-enteric products under-deliver — dose alignment and label honesty is scored second.
- 4
Supporting botanicals
Some formulas add caraway or ginger for extra antispasmodic/carminative effect. Useful, but the enteric peppermint core is what carries the evidence.
What to expect from enteric peppermint oil
Early easing
Cramping and bloating can ease within days for responders. Take enteric capsules before meals; if you get minty burps or heartburn, the coating failed — switch products.
The trial window
IBS symptom relief in studies builds over the first weeks of consistent dosing. Effect is real but individual — peppermint helps a meaningful subset, not everyone.
Sustained management
Continued use maintains the antispasmodic benefit for ongoing IBS management. It manages symptoms; it does not cure the underlying condition.
Delivery decides success
If peppermint 'did nothing,' verify it was genuinely enteric-coated and adequately dosed before concluding it failed — most disappointments are delivery failures.
The bottom line
IBgard (#1) is the pick for the most-studied IBS-specific peppermint oil.
Ultra-purified peppermint oil in patented SST microspheres targets the small intestine — the formulation behind the best modern trial (Cash 2016, 40% symptom reduction at 4 weeks) — with the lowest heartburn risk. It's the most expensive per dose, around $30/month.
Pepogest (#3) is the smartest default value; Heather's (#2) if peppermint has given you reflux before.
Nature's Way Pepogest (#3) hits the exact 0.2 mL clinical enteric dose at the best value. Heather's Tummy Tamers (#2) adds an extra enteric coat plus ginger and fennel for sensitive stomachs; Regimint (#4) is the European peppermint-caraway combo for dyspepsia overlap, and NOW Gels (#5) the best enteric bulk value.
Buy an enteric or SST form, hit the clinical dose, and give it a few weeks.
The trial range is roughly 180-225 mg per dose up to three times daily, so a 50 mg softgel means taking three or four to reach one clinical dose. Take it 30-90 minutes before meals and judge it only after the weeks the trials needed. The one disqualifying caveat: never buy a non-enteric softgel for gut symptoms.
Quick Answers
What is the best peppermint oil pick overall?
IBgard Peppermint Oil Capsules, 48ct by IBgard is our #1 pick (SAC score 9.4/10). If you want the peppermint oil with the strongest IBS-specific evidence and the lowest heartburn risk, IBgard is the pick. The SST delivery system was built specifically to solve peppermint's two problems at once — get the oil to the intestine and keep it out of the stomach — and it's the formulation behind the best modern trial in the category. You pay for it, and the small box empties quickly during a flare. But for a first serious attempt at controlling IBS pain, urgency, and bloating with peppermint, this is the most reliable place to start.
What is the best budget option?
Nature's Way Pepogest Enteric Peppermint Oil at $10 / month. Pepogest is the value gold standard and the smartest default for most buyers. It hits the precise 0.2 mL enteric dose the trials used, it's honestly labeled, and it costs a fraction of the engineered options — there's no cheaper way to get the clinically validated peppermint dose into your intestine intact. The only reasons to spend more are IBgard's stronger evidence and SST delivery (#1) or Heather's extra coat for severe reflux sensitivity (#2). For everyone else weighing cost against efficacy, start here.

How were these picks ranked?
Each pick was scored 0-10 across five criteria, then weighted to a final composite. Enteric coating / gut-targeted delivery carries by far the most weight because peppermint oil is the textbook case of a supplement whose label dose is meaningless if it releases in the wrong place — oil freed in the stomach relaxes the esophageal valve and causes the reflux/heartburn that peppermint is notorious for, and burns off before reaching the intestine where the antispasmodic effect lives. Clinical-dose alignment and label honesty is second: the trial-validated dose is roughly 180-225 mg of peppermint oil per capsule (the classic 0.2 mL softgel), taken up to three times daily, and we reward bottles that hit that range and clearly state their enteric claim. Third-party testing is the quality gate. Cost per effective (gut-delivered) dose is the tiebreaker, and real-world IBS/bloating response and tolerability anchor the math against the trial record.

- [1] Khanna 2014 PMID 24100754 — Peppermint oil for the treatment of irritable bowel syndrome: a systematic review and meta-analysis. Systematic review and meta-analysis of randomized placebo-controlled trials: enteric-coated peppermint oil was significantly superior to placebo for global improvement of IBS symptoms and for abdominal pain. The core modern evidence base for peppermint oil in IBS — and the reason the ranking treats the enteric-coated form as the validated one.
- [2] Ford 2008 PMID 19008265 — Effect of fibre, antispasmodics, and peppermint oil in the treatment of irritable bowel syndrome: systematic review and meta-analysis. Systematic review and meta-analysis in the BMJ: fibre, antispasmodics, and peppermint oil were all effective for IBS, with peppermint oil showing the strongest treatment effect of the three (number needed to treat of about 2.5). Establishes peppermint oil as a front-line, evidence-backed IBS therapy rather than a fringe remedy.
- [3] Cash 2016 PMID 26319955 — A Novel Delivery System of Peppermint Oil Is an Effective Therapy for Irritable Bowel Syndrome Symptoms. 4-week randomized, double-blind, placebo-controlled trial (IBSREST) of an ultra-purified, sustained-release small-intestine-targeted peppermint oil (the IBgard SST formulation) in IBS-M/IBS-D: 40% reduction in Total IBS Symptom Score at 4 weeks vs 24.3% for placebo (P=0.0246), with relief beginning within 24 hours and good tolerability. The evidence behind the #1 pick's SST delivery system.
