Quercetin / B5 Complex


One of several bioflavonoids (special nutrients found with vitamin C in fruit and vegetables) with anti-inflammatory, anti-oxidant and anti-histamine properties. Quercetin consistently demonstrates the greatest activity among the flavonoids studied, with many medicinal plants owing much of their activity to their high quercetin content. Quercetin may also help prevent nerve, eye and kidney damage in those with diabetes. In addition, bioflavonoids strengthen capillary walls, which helps prevent spider veins, varicose veins, and hemorrhages and bruises. They also work as an anti-inflammatory agent by deactivating enzymes that produce inflammation.

Vitamin B5 (pantothenic acid)

Found in varying amounts in virtually every food, hence its name derived from the Greek pantos, meaning everywhere. It is a water-soluble vitamin that has a key role in the release of energy from foods. It is also needed for healthy growth and the production of antibodies to help fight infection.


An enzyme found in the stem of the pineapple plant that helps digest food and absorb nutrients.


200-400 mg quercetin daily 20mins before meals (three times daily).

Potential applications

Quercetin appears to be indicated in virtually all inflammatory and allergic conditions, including hayfever, arthritis, lupus, food allergies, eczema and psoriasis.

Known contraindications

Although useful as an adjunct therapy, diabetes sufferers should consult their physician before using nutritional supplements such as quercetin.


No known interactions with quercetin and drugs.

Use in conjunction with

  • Arthritis - Glucosamine, boswellia, antioxidants, flax seed oil
  • Allergies - Ester-C, antioxidants, echinacea, multi-vitamin/mineral
  • Inflammation - Antioxidants, grape seed/pycnogenol, flax seed oil, multi-vitamin/mineral
  • Hyperglycemia - Chromium complex, trace minerals, green food blend
  • Eczema - Hemp seed oil, multi-vitamin/mineral, zinc complex
  • Psoriasis - Milk thistle, flax seed oil, grape seed/pycnogenol, antioxidants


Combinations of protein-digesting enzymes, like bromelain, when used with quercetin have been shown to potentiate each other's anti-inflammatory activity.
