Nutrients connected to Hay Fever
A link means the body needs the nutrient for this, or that low intake is linked to it. It does not mean extra supplements help if your intake is already adequate; each link shows how strong the evidence is.
- Pine pollenDocumented risk
Pine pollen is an allergen for some pollen-allergic people; the cited study did not test supplements.
- Polyphenols: quercetin and resveratrolPreliminary or mixed
One small placebo-controlled trial of an absorbable quercetin product lowered some hay fever symptom scores; a 2025 review said larger trials are needed. Not a treatment.
- CinnamonPreliminary or mixed
Preliminary research on a Ceylon cinnamon extract nasal spray; more reliable evidence needed.
- ButterburPreliminary or mixed
Studies of an oral leaf extract suggest it may help hay fever symptoms; evidence is limited.
- Almond mushroom (Agaricus subrufescens)Preliminary or mixed
In a 60-person trial in birch-pollen-allergic blood donors, symptom and medication reports were lower with the extract; needs confirmation.
