Quercetin for immune support
Quercetin is a flavonoid that’s naturally present in a wide range of frequently consumed foods, including apples, onions and berries. The quercetin in Fusion Quercetin Advanced is derived from the traditional Chinese medicine (TCM) herb Sophorae japonica, also known as huai mi or Japanese pagoda tree.

Quercetin exerts a variety of important therapeutic actions in the body, including:

Maintaining healthy immune system function
Reducing inflammation
Relieving mild allergy symptoms and reducing their occurrence
Reducing free radicals in the body through its actions as an antioxidant
Quercetin and vitamin C benefits
When it comes to antioxidant activity, quercetin and vitamin C are synergistic nutrients; meaning they work together to produce a combined effect greater than when they work alone. Vitamin C recycles quercetin in the body which supports the antioxidant actions of quercetin.

Both quercetin and vitamin C:

Support immune system health
Decrease symptoms of mild allergies and their frequency
Reduce the formation of free radicals in the body via their antioxidant activity
Vitamin C also supports the immune system to fight illness and relieves hayfever (allergic rhinitis) symptoms.

Zinc and lung health
Zinc plays an important role in the body, where it maintains lung health by supporting the health of the mucous membranes of the respiratory tract.

Zinc has several other important therapeutic benefits, including:

Maintains healthy immune system function alongside quercetin, and vitamins C and D
Helps the immune system to fight illness like vitamins C and D
Antioxidant activity similar to quercetin and vitamin C
Quercetin Advanced contains zinc glycinate, a highly bioavailable form of zinc for superior absorption, compared to other forms such as zinc gluconate.

Vitamin D for immunity
Alongside zinc and vitamin C, vitamin D supports healthy immune system function including helping the immune system to fight illness.Fusion Quercetin Advanced combines quercetin with zinc and vitamins C and D to support immune system health. Quercetin also reduces inflammation and relieves mild allergy symptoms and their frequency.
