Lamberts® quercetin is extracted from a natural plant source and each tablet provides a full 500mg of pure quercetin.
Quercetin is found in many fruits and vegetables, with apples and onions contributing most to the typical UK diet. Each 500mg tablet provides significantly more quercetin than 1 kilo of apples. Quercetin is probably the most researched bioflavonoid as it is recognised as being more active in the body than most others.
