Our seasonal allergy saviour: Quercetin Plus 

What is quercetin?


Quercetin is a naturally occurring plant flavonoid found in a range of fruits and vegetables. It's best known for its antioxidant power and its role in supporting the body’s natural histamine response. Quercetin is thought to help support mast cell stability, which may assist in maintaining a balanced immune response. 

While you can get quercetin from your diet, many people find that taking it regularly (especially at the start of allergy season) offers more consistent support. 

Quercetin Plus - A formulation deep dive:

  • Quercetin a natural flavonoid found in a range of fruits and vegetables and reduces histamine levels. 
  • Vitamin C can naturally balance histamine levels, supports the immune system and reduces tiredness and fatigue. Supports absorption of quercetin. 
  • Bromelain reduces inflammation in general and nasal inflammation in particular. Supports absorption of quercetin. 
  • Beta 1-3, 1-6 glucans support the immune response and over reaction in allergies. 
  • Luteolin a naturally occurring flavonoid, found in many fruits, vegetables and herbs and improves allergy symptoms.

Boost your diet with other natural antihistamines 

Most people turn to antihistamines for hay fever, but simple natural, anti‑inflammatory foods may also help ease symptoms. Here's a couple that you may not expect... 


  • Local honey – Contains tiny amounts of local pollen, which may help your body build tolerance over time. You can often find this in a nearby farm shop.
  • Garlic – A natural antihistamine with immune‑supporting properties and quercetin; helps inhibit histamine release from mast cells. Try adding some extra garlic to a tray of roasted veggies or even crushed into salad dressings and dips. 
  • Berries – Rich in antioxidants and vitamin C, which supports DAO — the enzyme that helps keep histamine levels balanced. Delicious as a snack or added to yoghurt, porridge, smoothies or salads. 
  • Ginger – A natural anti‑inflammatory that also helps reduce histamine release. Pop some in warm water with a slice of lemon (for extra vitamin C) for a soothing drink, add a little local honey for sweetness. 
  • Red onion – High in quercetin, helping calm cells that react to airborne allergens like pollen and dust mites. Great added raw to salads or sandwiches.
