Force of nature from the plant world
- Quercetin is a powerful flavonoid derived from natural sources and highly valued in modern nutritional science for its antioxidant properties.
- In nature, quercetin serves as a protective mechanism for plants, shielding them from harmful environmental influences such as UV radiation and pathogens. This contributes to the robustness of the Japanese pagoda tree, which serves as the primary source for quercetin extraction.
A flavonoid for well-being
- The use of quercetin in Green Naturals combines centuries-old knowledge of botanicals with state-of-the-art science. Meanwhile, numerous scientific studies prove its positive effects on the body.
Commitment to Quality and Purity
- Each Green Naturals capsule contains 500 mg of pure natural quercetin, extracted from the Japanese Pagoda Tree (Sophora japonica), with no added synthetic substances.
- Manufacturing in Germany guarantees the highest production standards and continuous quality control to ensure optimal efficacy and safety.
- Our commitment to sustainability is reflected in the vegan formulation and the use of capsule shells made from plant-based cellulose, making Green Naturals an environmentally friendly choice.
