They are a dietary supplement capable of delivering active oxygen to the body systemically. O3ZONE capsules promote overall wellness by improving oxygen delivery to the muscles, helping to reduce fatigue, accelerate recovery, and strengthen the body’s resilience. This is achieved through the stimulation of endogenous antioxidant production and reduction of inflammation.

Since they are made only from natural elements—oxygen and lipids essential to our cells (essential fatty acids)—they are free of side effects.

They increase oxygen availability, especially to the muscles. As a result, the sensation of tiredness decreases, while the feeling of available energy and general well-being increases.

Ozonides are the bonds by which oxygen is linked to oils. It is a stable, non-reactive bond that releases oxygen only inside the cells.

O3ZONE stands out for its extremely high purity of components and a unique amount of active oxygen. Additionally, the oxygen is adsorbed on powder to allow for a gradual release in the intestine, avoiding any side effects. Our capsule preparation system is patented, and therefore unique.

At low doses: to improve health and prevent fatigue.

At medium doses: for anti-inflammatory effects.

At high doses: as a supportive aid in individuals recovered from or with stabilized cancer conditions.

At low doses, it induces the endogenous production of antioxidants by activating the Antioxidant Responsive Elements, allowing the body to select the most suitable antioxidants for its condition. Through this mechanism, O3ZONE is more effective and more physiological than the external administration of high doses of specific antioxidants.

Six years of preclinical research and four years of clinical application have led to a thorough understanding of the mechanisms of action and the development of highly effective and safe formulations. The studies were conducted by independent academic institutions and published in leading international scientific journals.

Yes, they are made solely from plant-based compounds and oxygen.

Yes.

They can be stored for up to 7 days at room temperature, provided it's below 25°C. For longer periods, it is preferable (though not necessary) to store them at temperatures below 15°C.

Up to 7 days, as long as the temperature stays below 25°C.

Highly purified vegetable oils, highly purified oxygen, cellulose, algae.

Sunflower oil is a blend of vegetable oils. Pantothenic acid is a heat-sensitive vitamin (Vitamin B5) that acts as a cofactor for Coenzyme A, used by cells to produce metabolic energy.

The dosage: respectively 150, and 350 mg of ozonised oil adsorbed. Additionally, O3ZONE Plus uses pure oleic acid, while O3ZONE 00 uses sunflower oil.

The dose of 10 capsules is the maximum allowed. However, it may be exceeded following personalised recommendations from your doctor.

The label shows the standard generally recommended dose. However, in specific conditions such as inflammatory states, a doctor or specialist may suggest a higher dose for a more targeted effect. Always follow the personalized guidance of your healthcare professional.

From highly purified oils and oxygen, certified to the highest standards and processed under accredited, controlled conditions.

Yes. Independent academic and accredited laboratories have tested the quality, stability, and effectiveness of the products.

O3ZONE is certified in accordance with the regulations of the Ministry of Health of Italy, Belgium, Czechoslovakia, Estonia, Finland, France, Germany, Ireland, Latvia, Luxembourg, Malta, Portugal, Slovakia, and Sweden — and O3ZONE Sport is certified by the Cologne List®: no doping, no long-term side effects.

O3ZONE products are made exclusively from natural ingredients like oils and oxygen and generally have no side effects. In very rare cases (≤1%), a mild sensation of bloating or intestinal gas may occur during the first few days of treatment, which usually resolves on its own.

Capsules should be swallowed on an empty stomach, ideally at least 60 minutes before or after meals.

If swallowing is difficult, capsules can be opened and the contents emulsified in water, although this may reduce effectiveness by about 30% due to interaction with acidic gastric pH.

At least 30 minutes, preferably 1 hour.
