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. 1. Stop colds faster without resorting to antibiotics.
  2. 2. Soothe digestion (bloat, gas, SIBO-like discomfort) instead of just masking it with antacids.
  3. 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 Majestic Pure Oregano Essential

Majestic Pure Essential Oil

Overall Rating: 4.1/5

NOTE: This is NOT a supplement, so don’t try to drink it!

This is an oil that you can use in a diffuser (or while making soaps and candles). And it’s great for doing that!

But – putting it in a diffuser won’t address gastrointestinal issues, bloating, stomach pain, or cold and flu symptoms.

It’s a great choice for making nice-smelling soap, though, and it has great ratings. Just know that it isn’t the best way to use oregano oil if your goal is to improve bloating or sinus pain.

Pros

  • Big 1 fl oz bottle offers strong value per milliliter
  • Dropper makes controlled dosing easy for diluted topical use and foot soaks
  • Versatile for home uses like diffuser, cleaning mixes, and DIY blends
  • Widely available on Amazon with lots of buyer feedback

Cons

  • Essential oil, not a supplement; not for internal use
  • Must be diluted; undiluted oil can irritate skin
  • No listed carvacrol percentage, so potency is unclear
  • Limited penetration through thick, damaged nails; requires patient daily use

#4 Oreganol - North American Herb & Spice

Oreganol

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 Nutrivora Oil‑of‑Oregano

Nutrivora Oil-of-Oregano

Overall Rating: 3.9/5

Nutrivora markets itself as a candida‑focused oregano blend. Each softgel delivers a “6 000 mg herbal‑equivalent” dose of oregano oil plus 200 mg of black‑seed oil in a small, easy‑swallow capsule. Users online note gentler digestion and some reduction in sugar cravings after a month, although several complain about a pre‑checked auto‑ship box that can trigger surprise rebills. The bottle holds just 60 caps - enough for one month - so cost rises quickly if you stay on the program.

Pros

  • Oregano + black‑seed combo targets gut and immune support
  • Non‑GMO and free of gluten, soy, and dairy
  • Small capsule; little to no after‑taste
  • Thirty‑day money‑back guarantee

Cons

  • Auto‑ship box pre‑checked at checkout (watch for rebills)
  • Higher cost per day—around $1.30 for a full dose
  • Brand provides limited company details beyond funnel pages
  • Countdown‑timer sales tactics can feel high‑pressure

#6 Resilia Oil‑of‑Oregano Softgels

Resilia Oil‑of‑Oregano Softgels

Overall Rating: 3.7/5

Resilia leans on minimalist, clean‑label branding: oregano oil plus black‑seed oil in a vegan softgel with no added fillers. Fans online praise the tasteless capsule and gentle stomach feel, while several reviews mention shipping delays and subscription upsells appearing too early in the checkout flow. With only 60 capsules per bottle, the per‑dose cost settles around fifty cents, putting it in the mid‑premium range.

Pros

  • Vegan capsule, free of major allergens
  • Oregano + black‑seed pairing for broad herbal support
  • Thirty‑day refund policy
  • Frequent “buy 2, get 1” bundle discounts

Cons

  • No publicly shared quality certificates—only a generic badge
  • Some reports of shipping lags and aggressive subscription prompts
  • Small bottle size means a higher monthly spend if used long term
  • Marketing promise of “results in 7 days” may set unrealistic expectations

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.
