We make most of our ozonated products in-house. For olive oil capsules, we did a worldwide search for a manufacturer who could meet three standards:.
The manufacturer that best meets all three is based in Europe, where ozone has been a part of mainstream medicine for more than a century.
That’s a long trip for a small capsule, but we think it’s worth every mile.

Organic olive oil
Biotechnological Hyperoxidation process
Made to strict European standards ensure the final product is at least 600 peroxide value.
Third-party tested organic, extra virgin olive oil. No solvents. No additives.
Cold-processed at 48°F to avoid the formation of aldehydes, including formaldehyde.


Ozonated olive oil is more than just olive oil with ozone mixed in.
When ozone is diffused through olive oil, it bonds with the oil's unsaturated fatty acids to form stable new compounds called ozonides and peroxides.
These are the molecules that do the work.
The "600 peroxide value" you see on our label is a direct measurement of those compounds.
Higher numbers, more transformation, more potency.
Most ozonated oils on the market are produced at room temperature or warmer, which accelerates ozonation but comes at a cost:
Heat drives the formation of aldehydes, including formaldehyde, along with other inflammatory byproducts.
Our olive oil is ozonated at a steady 48°F over a much longer period.
The result is more of the ozonides and peroxides you want, and less of the byproducts you don't.

Capsules are cleaner, more convenient, and more shelf-stable. There's no measuring, no oily aftertaste, no mess, and no need to refrigerate. The sealed capsule also protects the oil from light and oxygen so each capsule stays at full potency for years.
Two capsules daily, preferably on an empty stomach.
Two ingredients: organic extra virgin olive oil that's been ozonated to a minimum peroxide value of 600, and a vegan capsule made from pine or poplar tree fibers. No fillers, no solvents, no additives.
Peroxide value is a measurement of how much ozone has been incorporated into the oil. The higher the number, the more potent the product. Ours comes in at a minimum of 600. Most brands won't tell you their peroxide value. (Usually because they have no idea what theirs is.)
Regular olive oil is a food. Ozonated olive oil has been chemically transformed by ozone gas into something structurally different: thicker, more shelf-stable, and far more potent. They look similar but behave very differently.
No. The capsule shell protects the oil from light and oxygen, so the product stays shelf-stable for at least three years at room temperature. Refrigeration is fine but not necessary.
Two reasons: the oil itself is significantly more potent than typical competitor products, and it's produced overseas in a certified biotechnology facility using a patented cold-process method that takes much longer than conventional ozonation. You're paying for a higher-grade product, not a larger one.
Yes. The oil is plant-based and the capsule shell is made from pine or poplar tree fibers. No gelatin, no animal products.
Yes. The oil is third-party tested and produced in a facility certified to ISO 22716:2007 (Good Manufacturing Practices) and ISO 9001:2015 (Quality Management). The olive oil itself is COSMOS Certified organic.
We sell our ozonated oils separately for topical use, and we'd recommend those products if that's your goal. The capsules are designed and dosed for oral use.
At two capsules a day, a 120-count bottle lasts 60 days.
We offer a 30-day return policy. If you're not satisfied, you can return it within 30 days (even if opened). You're responsible for return shipping.
