What makes Sanazia Quercetin special?
Quercetin is a powerful antioxidant that protects cells from damage and ageing. It acts as a protective shield against harmful substances that arise in the body due to stress, inflammation or an improper diet. Quercetin also supports heart and vascular health by helping to maintain healthy blood pressure and vessel patency. In addition, it calms inflammation and allergic reactions, supporting the body's natural defences.
Sanazia Quercetin contains 200 mg of highly pure 97% quercetin extract in a single capsule. This dose is suitable for long-term use and supporting antioxidant protection. The capsule form allows precise dosing and convenient use. The high 97% purity ensures the maximum amount of active substance in every capsule.
Our quercetin is obtained from natural sources rich in flavonoids, such as onions and apples, using advanced extraction methods. The extract is then purified to 97% purity, ensuring the maximum amount of active substance in every capsule. Every production batch is tested using HPLC analysis to confirm quercetin content, purity and the absence of contaminants. The product is also tested for heavy metals and microbiological safety.
The effectiveness of quercetin is backed by scientific research. A meta-analysis of 9 randomised controlled trials (Serban et al., 2016) showed that quercetin supplementation significantly reduced systolic blood pressure by 3.04 mm Hg and diastolic blood pressure by 2.63 mm Hg, with the most pronounced effect observed at doses ≥ 500 mg daily. These results confirm that quercetin is an effective tool for supporting cardiovascular health.
Supporting cardiovascular health is a long-term process that requires regular, consistent supplementation with quercetin. The effect is not immediate but develops gradually as antioxidant and anti-inflammatory processes stabilise. For maximum benefit, long-term use combined with a healthy lifestyle is important. Quercetin is safe for long-term use and is suitable for people who want to maintain healthy blood pressure and support cardiovascular health.
