Top 6 Oregano Oil Supplement Brands Reviewed for 2025

We tested the most popular Oil of Oregano brands and put everything you should know about them in this quick guide

If a scratchy throat turns into your third cold this season, your stomach balloons after every meal, or the same yellow spot keeps creeping across a toenail, you’re in the right place. We spent the last weeks swallowing, swishing, and testing the six most-searched oil-of-oregano capsules sold in the U S. market. Our goals were simple:

1. Stop colds faster without resorting to antibiotics.
2. Soothe digestion (bloat, gas, SIBO-like discomfort) instead of just masking it with antacids.
3. Keep nails and skin clear from stubborn yeast - no messy creams or prescription pills.

Every brand was scored on five criteria: carvacrol potency, gut tolerance, third-party testing, price per mg, and real-world user feedback. While TrustedConsumersReviews shares a parent company with some of the reviewed brands, including Lumivyx, we remain committed to honest comparisons that put product performance and consumer value first.

Below you’ll find deep-dive summaries - pros, cons, and who each brand fits - followed by a head-to-head comparison chart of the top three performers.

#1 Fortifyx Oil of Oregano + Black Seed

Fortifyx

Overall Rating: 4.9/5

The first thing we noticed was zero oregano “pizza burp.” Fortifyx’s enteric shell kept its wild 60% carvacrol and black-seed thymoquinone locked away until the capsule hit the intestine - so no throat burn, just results.

On day two the scratchiness in our tester’s throat eased; by week two her post-meal bloat had vanished. Nail photos taken at week eight showed the yellow edge shrinking - impressive results for a very affordable price.

Pros

Highest verified carvacrol dose (≈ 165 mg)
Dual-action formula targets immune & digestive health
Made with non-GMO, allergen-free ingredients
Black-seed synergy settles gut & boosts absorption
Enteric coating - no reflux or after-taste
Customizable Comfort: With three adjustable speeds, you can tailor your cooling experience to your exact preferences, making it perfect for intense heat waves.
cGMP U S-made, third-party potency & heavy-metal tests posted
Only 2 softgels per day - no messy drops
BPA-free bottle & eco-friendly packaging
30-day money-back guarantee

Cons

Only sold online (can’t grab in Whole Foods)
Two-a-day schedule—set a reminder if you’re forgetful

#2 Gaia Herbs Oil of Oregano

Gaia Herbs

Overall Rating: 4.3/5

Gaia’s vegan Phyto-Caps are as clean as they come—CO₂-extracted oil, organic farms, and QR codes that open lab reports. Potency is moderate (~32 mg carvacrol), so we reached for it mainly during the first tingle of a cold. Great for plant-purists, but at thirty-cents a pill you’re paying a lot per milligram.

Pros

Certified organic, B-Corp transparency
Vegan capsule, no soy or gelatin
No detectable after-taste

Cons

Potency about half of Fortifyx—slower gut/fungus results
Premium price ($0.32 / cap)
No additional soothing co-actives

#3 NOW Foods Oregano Oil Softgels

NOW Foods

Overall Rating: 4.1/5

NOW Foods Oregano Oil is a solid but unremarkable herbal supplement for those seeking mild immune support. Its strength lies in its standardized potency and straightforward formulation, offering a decent dose of carvacrol, the compound often credited for oregano’s antimicrobial reputation.

However, its intense taste can be off-putting, and its effects are subtle rather than dramatic. Overall, it’s a reasonable, budget-friendly option for natural wellness routines, but far from a standout in the crowded herbal supplements aisle.

Pros

Under $20 for 180 caps
Widely available, good Subscribe-&-Save deals
Added ginger/fennel aids light digestion issues

Cons

Soy-based softgel—not vegan
Mid-low potency; results took longer
No money-back guarantee

#4 North American Herb & Spice Oreganol P73

Oreganol P73

Overall Rating: 3.9/5

The OG of wild oregano. We respect the heritage, but even encapsulated the peppery kick lingered. Strong at fighting fungus, yet the $34 price for 120 caps stings harder than the taste.

Pros

Genuine wildcraft “P73” chemotype
Long track record with holistic doctors
Enteric-like shell cuts some burn

Cons

Highest cost on list
Lingering oregano smell on breath
Lot testing only on request

#5 Micro Ingredients Oregano + Black Seed 6000 mg

Micro Ingredients Oregano + Black Seed 6000 mg

Overall Rating: 3.9/5

We wanted to love the massive milligram headline, but lab sheets showed about half the carvacrol we expected, and no enteric coating meant three of five testers felt heartburn. Still, it’s a cheap way to try the oregano-plus-black-seed concept.

Pros

Combines the two headline oils
300-cap bulk under $35
Non-GMO formula

Cons

Reflux in sensitive users
No posted heavy-metal or purity data

#6 Puritan’s Pride Oil of Oregano 150 mg

Puritan’s Prid

Overall Rating: 3.7/5

Classic bargain bin. At 15 mg carvacrol per cap it’s best for light “maintenance.” Great if you’re on a tight budget, but don’t expect miracles for nail fungus.

Pros

Cheapest per pill (often BOGO)
Long-time brand trust
Easy to find offline

Cons

Lowest potency in the test
Soybean oil carrier
Minimal third-party documentation

Conclusion

If you need one capsule that acts fast on colds, keeps your gut calm, and makes progress against stubborn nails, Fortifyx is your move. Gaia wins for vegan purity, NOW for rock-bottom cost—yet neither matches Fortifyx’s potency-per-dollar or its reflux-free delivery.
