How It Works

How Quercetin Works

Quercetin exerts its effects through multiple mechanisms:

  1. Antioxidant Activity: It scavenges free radicals, preventing them from damaging cells.
  2. Anti-Inflammatory Action: It inhibits the production of inflammatory molecules, reducing inflammation throughout the body.
  3. Immune Modulation: It regulates immune cell activity, supporting a healthy immune response.
  4. Mast Cell Stabilization: By inhibiting the release of histamine and other inflammatory substances from mast cells, it is able to reduce the severity of allergic reactions.
