Seasonal Allergies

Support a balanced histamine response through allergy season

  • Seasonal support without drowsiness
  • Natural histamine regulation
  • Supports comfort through congestion, sneezing and itching

A three part protocol targeting the inflammatory cascade and histamine response that drives seasonal allergy symptoms. Hesperidin (150mg per capsule) is a citrus bioflavonoid that stabilises mast cells and reduces histamine release, paired with 100mg bromelain (1200 GDU/g) which reduces nasal mucosal inflammation and enhances the absorption of other anti inflammatory compounds.

Inflammite provides broad spectrum anti inflammatory support: 62.5mg turmeric (95% curcuminoids), 50mg quercetin, 75mg olive leaf extract (20% oleuropeine), 25mg resveratrol extract, 25mg marine pine bark (95% OPC), 50mg vitamin C, vitamins A, D3, E with tocotrienols, K2, B6, magnesium and astaxanthin. Piperine enhances curcumin absorption by up to 2000%. Standalone Quercetin at 250mg per capsule provides additional mast cell stabilisation and is one of the most researched natural antihistamines, inhibiting both histamine release and the inflammatory cytokines that drive the allergic cascade.

The combination addresses allergies through three mechanisms: preventing histamine release (quercetin and hesperidin as mast cell stabilisers), reducing the inflammatory response once triggered (curcumin, bromelain, OPC, resveratrol) and supporting immune regulation (vitamins A, C, D3, zinc).

Hesperidin Capsules

Calms inflammatory allergy symptoms such as itchy noses and eyes

Ingredients

Hesperidin, Bromelain, Hydroxypropyl Methylcellulose (capsule).

Hesperidin is a flavonoid found in citrus fruit, and this extract comes from bitter orange, standardised for its hesperidin content. The capsule pairs it with bromelain, an enzyme from pineapple stem.

Hesperidin is the citrus flavonoid most studied for the veins and capillaries. Bromelain is included because the two are traditionally taken together.

Each capsule provides hesperidin and bromelain with nothing else apart from the vegetable shell. It is often chosen by people who want hesperidin on its own rather than in a mixed formula.

Inflammite Capsules

Turmeric, quercetin and astaxanthin together in one capsule.

Ingredients

Magnesium Citrate, Hydroxypropyl Methylcellulose (capsule), Olive Leaf extract, Turmeric, Ascorbic acid, Quercetin, Astaxanthin powder, Polygonum Cuspidatum extract, Marine Pine Bark ext, Menaquinone 7, EVNolMax TM20% (ExcelVite), Beta Carotene powder, Pyridoxal 5 Phosphate, Cholecalciferol, Piperine, Zeaxanthin Powder.

Inflammite combines vitamins A, C, D3 and E with magnesium, zinc, olive leaf extract, turmeric, quercetin and astaxanthin. It is a broad formula rather than a single extract.

Vitamin C and zinc contribute to the normal function of the immune system, magnesium to muscle function, and vitamins C and E to the protection of cells from oxidative stress. The plant extracts are the ones most used alongside them in practitioner formulas.

Two capsules twice a day with meals provides the amount. It is often chosen by people who want the nutrients and the plant extracts together rather than in separate bottles.

Quercetin Capsules

Quercetin, a plant flavonoid found in onions and apples, 250 mg per capsule

Ingredients

Quercetin, Hydroxypropyl Methylcellulose (capsule).

Quercetin is a flavonoid, a plant pigment found in onions, apples, capers and tea. This extract comes from the buds of Sophora japonica, a plant grown for its flavonoid content.

Flavonoids are the compounds behind many of the effects credited to fruit and vegetables. People take quercetin as a supplement in amounts food cannot provide, often with bromelain or vitamin C.

Each capsule provides quercetin with nothing else apart from the vegetable shell. It is often taken with meals, and it is the ingredient at the centre of several Nutri Tailor formulas.

  • Hay fever symptoms
  • Allergic rhinitis
  • Contact allergies
  • Hives
  • Environmental allergies
  • Eczema
  • Asthma
  • Chemical sensitivities 
  • General immune function
  • Inflammatory symptoms

Take 2 Hesperidin capsules, 2 Inflammite capsules and 2 Quercetin capsules per day with food, split between breakfast and lunch.

For best results, begin the protocol 4 to 6 weeks before allergy season starts, as the mast cell stabilising effects build over time. The quercetin and hesperidin need consistent daily dosing to maintain therapeutic levels. During peak allergy season, the Quercetin dose can be increased to 3 capsules daily (750mg).

Taking with food supports absorption and tolerability. Avoid taking quercetin at the same time as thyroid medication, as it may affect thyroid hormone levels at high doses. The bromelain in the Hesperidin formula is derived from pineapple; those with pineapple allergy should use the standalone Quercetin and Inflammite without the Hesperidin.

Lifestyle tips

How to boost your results

Avoid histamine containing and liberating foods

Histamine naturally develops in food as it matures so anything aged like cheese, fermented vegetables, alcohol and cured meat or fish will contain high amounts which will exacerbate symptoms. Additionally, some foods encourage more histamine to be released by the body so it is also advisable to limit these during allergy season. They are spinach, strawberries, citrus fruits, nightshade vegetables (aubergine, tomatoes, peppers, chilli, and white potatoes), cacao or chocolate products, coffee and mushrooms.

Increase intake of natural antihistamines

In the same way that the foods mentioned above will add to histamine burden, other foods will naturally decrease symptoms by blocking its actions. Raw red onions, fresh parsley, nettles, broccoli and green tea can be helpful here.

Be aware of the impact of exercise

Histamine is produced in muscles as we exert ourselves to help recovery. If you are really suffering it would be advisable to stick to lower intensity activity to prevent this from causing another influx of histamine to the system.

Frequently asked questions

How does this plan help with seasonal allergies?

Per NICE CKS Allergic rhinitis, first-line management is intranasal corticosteroids (fluticasone, mometasone) for moderate-to-severe symptoms and oral second-generation antihistamines (cetirizine, loratadine, fexofenadine) for mild-to-moderate. This plan provides nutritional adjuncts: quercetin (500-1000 mg/day combined across Inflammite and standalone Quercetin) has well-described in vitro mast cell stabilising mechanism (Mlcek 2016 review, doi 10.3390/molecules21050623); human RCT evidence in allergic rhinitis specifically is limited. Bromelain (100-200 mg/day) is used adjunctively in some European countries for nasal congestion. Hesperidin and Inflammite anti-inflammatory micronutrients support the broader inflammatory cascade. Start 4 to 6 weeks before your typical pollen season for build-up time. Saline nasal irrigation has Cochrane-supported adjunct evidence. For severe or persistent symptoms, GP-led pharmaceutical care remains first-line.

When should I start taking allergy support?

Ideally 4-6 weeks before your allergy season begins.

Can I take this with antihistamines?

Generally yes. Consult your provider if taking prescription medications.

How do natural allergy supplements work?

They support the immune system's balanced response rather than just blocking symptoms.

What nutrients help with histamine?

Vitamin C, quercetin, and DAO enzyme help break down and regulate histamine levels.

Do you ship internationally?

Yes. We ship worldwide from the UK. Duties, taxes and delivery costs for your country are calculated and shown at checkout.
