5 Best Oregano Oil Supplements

We've scoured the market, tested numerous products, and narrowed down the top five oregano oil supplements that stand out for their quality, strength, and ease of use. Our evaluation criteria focused on three key aspects: carvacrol strength (because that is the part of oregano that does the work), gentleness (because a capsule that burns is so last year), and what else is in the softgel (because after 60, oregano alone is only half the story).

TLDR: Orgatics' Oil of Oregano with Black Seed Oil takes the crown, boasting a 70% carvacrol oil, a gentle nightly softgel, a black seed oil pairing, and a full 90-day guarantee. It's the perfect blend of strength and ease, ensuring steady support you can actually stay on. I take two Orgatics softgels every night and love it.

Here are the five best oregano oil supplements we've found:

1. Orgatics Oil of Oregano with Black Seed Oil

Taking the top spot with flying colors, Orgatics' Oil of Oregano with Black Seed Oil is in a different league from the rest of the oregano shelf. It features wild Mediterranean oregano oil standardized to a minimum of 70% carvacrol, combined with cold-pressed black seed oil, so one softgel supports healthy immunity and a healthy inflammatory response at the same time. What truly sets Orgatics apart is its ability to stay strong while being gentle: two golden softgels at night with water, no burn, no repeating taste.

The pouch is a full month, 60 softgels at 6,000mg per serving, lab tested and made in GMP-certified facilities. Coupled with a 90-day money-back guarantee and genuinely kind customer service, Orgatics has earned its place as the number-one choice for an oregano oil supplement.

2. Resilia Oil of Oregano Softgels

Securing our second spot is Resilia Oil of Oregano, notable for being the only other softgel here that pairs oregano with black seed oil. It is gentle, easy to swallow, and third-party tested, so it effectively covers the same ground as our number one.

Despite its similar formula, it falls slightly short in two places. The label gives carvacrol as 165mg per serving rather than a standardized percentage. In terms of risk, the guarantee is 30 days, which may not appeal to those who know oregano oil takes two to three months to show what it can do.

All in all, Resilia delivers a solid softgel, even if it means deciding in a third of the time, placing it comfortably at number two on our list.

3. NOW Foods Oregano Oil

NOW Foods Oregano Oil earns the third spot on our list, notable for its enteric-coated softgel that opens after the stomach. It prints its carvacrol standard right on the label, which already puts it ahead of most of the shelf.

Despite its honest label, it falls slightly short on strength. The oil is standardized to 55% carvacrol and blended with ginger and fennel oil, in one small 181mg softgel a day. In terms of formula, it is oregano alone, which may not appeal to those looking for inflammation support too.

All in all, NOW delivers a gentle, affordable softgel, even if it means compromising on strength and missing the black seed oil, which is why it sits at number three on our list.

4. Zane Hellas Oregano Oil Softgels

Snagging the fourth spot is Zane Hellas, showcasing the highest carvacrol number here: 86%, with 130mg of carvacrol in every softgel. It also has a loyal following among people who want the strongest Greek oregano they can find.

While it is undeniably potent, it was too much for me: heartburn, and a taste that repeated for hours. Despite its popularity, women my age may find it simply too strong, longing for a more balanced softgel they could take every night.

5. Gaia Herbs Oil of Oregano

Landing at the fifth position, Gaia Herbs Oil of Oregano is a clean liquid capsule from a brand that's garnered quite a bit of respect, especially in health food stores. Its careful testing and tidy label have made it a popular choice.

While it does deliver on quality, it falls short in the strength department, with 27mg of carvacrol per capsule, taken twice a day with meals. And if you're someone who wants support all winter, note that the label itself suggests no more than two to four weeks of use.

Despite its reputation, these practical drawbacks mean Gaia lands at number five on our list. Still, for a short seasonal burst, it remains a noteworthy option.
