WHAT MAKES THE O₄ COMPLEX UNIQUE?
1
Cellular Antioxidant Protection
The flavonoids in the formula possess powerful antioxidant properties that may help neutralize free radicals and reduce the harmful effects of oxidative stress.¹
2
Support During Inflammatory Processes
Quercetin and luteolin may help support a healthy inflammatory response and protect cells from oxidative damage.²˒³
3
Mental Clarity and Nervous System Support
Fisetin is one of the most extensively researched flavonoids today. Through its antioxidant and anti-inflammatory properties, it may help support healthy nervous system function and promote cognitive performance.⁴
4
Piperine for Enhanced Flavonoid Activity
Flavonoids often exhibit limited bioavailability in their natural form.⁵ In addition to its own beneficial physiological properties, piperine may help enhance the absorption and utilization of the other ingredients in the O₄ Complex, thereby supporting their overall effectiveness.⁶
5
Maximum Bioavailability with Liposomal Technology
A key feature of the formula is its use of advanced liposomal technology. Liposomes are tiny spherical structures with a membrane similar to that of human cells. They help protect active ingredients from degradation in the digestive system while enhancing their absorption and facilitating more efficient delivery into cells. As a result, the body is able to utilize a greater proportion of these valuable compounds.⁷˒⁸˒⁹˒¹⁰

O₄ COMPLEX INGREDIENTS
1
Quercetin
Quercetin is one of the best-known plant-derived flavonoids and is naturally found in significant amounts in onions, apples, berries, green tea, and citrus fruits.
Quercetin possesses powerful antioxidant properties that may help neutralize free radicals, thereby contributing to the reduction of oxidative stress and the protection of cells. It may also help support the regulation of the body's inflammatory responses by influencing the production of certain pro-inflammatory compounds. Through these mechanisms, quercetin may contribute to maintaining the body's natural balance and overall well-being.¹¹˒¹²
2
Luteolin
Luteolin is a plant-derived flavonoid naturally found in celery, parsley, chamomile, green peppers, and carrots. Known for its antioxidant properties, luteolin may help neutralize free radicals and protect cells from oxidative stress–related damage.¹³ Research suggests that luteolin may also influence certain inflammatory pathways and help modulate the production of inflammatory mediators, thereby supporting the body's natural balance and contributing to cellular protection.³
3
Fisetin
Fisetin is a plant-derived flavonoid naturally found in strawberries, apples, grapes, onions, and cucumbers.
Research suggests that fisetin may help protect nerve cells against oxidative stress and inflammatory processes.⁴ Due to its antioxidant and anti-inflammatory properties, it may support the healthy functioning of the nervous system.¹⁴ Studies also indicate that fisetin may have a positive influence on memory, learning processes, and cognitive function, while potentially helping to mitigate age-related changes in neurological health.⁴
