Features & Benefits:

Oriental Botanicals Quercetin Excel combines four key nutrients to support the immune system:

  • Relieves inflammation
  • Helps decrease mild allergy symptoms and reduce their occurrence
  • Antioxidant - reduces free radical formation in the body

Vitamin C

  • Supports the immune system in fighting illness
  • Reduces mild allergy symptoms, including hayfever (allergic rhinitis)
  • Works with quercetin as an antioxidant


  • Maintains healthy immune system function
  • Supports lung health by maintaining the health of the respiratory tract’s mucous membranes
  • Contains zinc glycinate, a highly bioavailable form of zinc that’s better absorbed than some other forms (like zinc gluconate)

Vitamin D

  • Maintains the function and health of the immune system, including its actions against illness

How it works:

Quercetin for immune system

Quercetin is a flavonoid that’s found in a variety of everyday foods including vegetables and fruits, leaves, seeds, and grains. The quercetin in Oriental Botanicals Quercetin Excel is extracted from the herb Sophorae japonica, also referred to as Huai Mi or Japanese pagoda tree, which is used in traditional Chinese medicine.

Quercetin has numerous benefits in the body, such as maintaining immune system health and function and relieving mild allergy symptoms and their frequency. It also has anti-inflammatory and antioxidant properties, and reduces free radicals in the body through its antioxidant actions.

Quercetin and vitamin C

Quercetin and vitamin C are a great team. Both having antioxidant properties, they work together to produce a synergistic therapeutic effect to reduce the formation of free radicals in the body, which is greater than if they worked alone. Vitamin C recycles quercetin in the body which supports the antioxidant activity of quercetin.

Not only do both quercetin and vitamin C support immune system health, but they also relieve symptoms of mild allergies and their occurrence.

Other well-known benefits of vitamin C include:

  • Supporting the immune system to fight illness

  • Relieving hayfever (allergic rhinitis) symptoms

Zinc and immune health

Similarly to quercetin and vitamin C, zinc also maintain healthy immune system function and plays a role as an antioxidant. Zinc also works alongside vitamin C to help the immune system to fight illness.

Zinc has an important supportive role in lung heath, by maintaining healthy mucous membranes of the respiratory tract.

Quercetin Excel contains zinc glycinate, a highly bioavailable form of zinc for superior absorption, compared to other forms such as zinc gluconate.

Vitamin D and immune function

Like vitamin C and zinc, vitamin D is an especially important nutrient when it comes to supporting healthy immune system function. It also aids the immune system in its actions against illnesses.
