Product Description

Dihydroquercetin, also known as taxifolin, is a flavonoid compound found in various plants, including the Siberian larch tree. It is known for its antioxidant properties and has been used in traditional medicine for its potential health benefits.

Dihydroquercetin has been found to have anti-inflammatory, anticancer, and antimicrobial effects. It is also believed to have cardioprotective properties and may help reduce the risk of cardiovascular diseases. Additionally, it has been shown to have hepatoprotective effects, protecting the liver from damage caused by toxins.

Studies have also suggested that dihydroquercetin may have anti-aging effects and can help improve skin health. It has been found to protect against UV-induced skin damage and may help reduce the appearance of wrinkles and age spots.

Dihydroquercetin is available as a dietary supplement and is often marketed as a natural antioxidant. It is generally considered safe for consumption, but like any supplement, it is important to follow the recommended dosage and consult with a healthcare professional before starting any new supplement regimen.
