PurO3 Ozonated Olive Oil combines organic, cold pressed, extra virgin olive oil and ozone, giving you an oxygen-rich, soothing salve. Ozonated olive oil is popular all over the world for a variety of uses. Fully ozonated oils: Oils that haven't been ozonated enough remain liquid even after they are refrigerated. PurO3's oils are fully saturated, with as much ozone as the oil can hold, creating a soothing salve. Certified organic ingredients: We only use 100% organic, cold-pressed, extra virgin olive oil. Cold ozone production with a high purity oxygen source: Some oils are ozonated with high heat machines and low quality oxygen. PurO3 uses only medical grade oxygen and ultra pure ozone. Glass packaging: No risk of BPA from plastic liners or plastic break-down over time. Refrigerated storage: Our oils are frozen before they are shipped to you, so they keep their potency longer. Refrigerated oils can last up to ten years. We've found that even at room temperature, our oils can last up to a year. Pure: No fillers, stabilizers, GMOs, preservatives or binders. Simple, safe and pure. 100% all natural and safe: No hidden ingredients. Made in the USA PurO3 Ozonated Olive Oil is powerful and fully saturated with ozone.
