Natural
Vitamin C (1–2g/day)
for Hay Fever
High-dose vitamin C has natural antihistamine properties and antioxidant effects that may reduce allergy severity during pollen season.
How it works
Acts as a reducing agent for histamine, accelerating its breakdown. Also inhibits prostaglandin synthesis and has mast cell stabilising properties at high doses.
What to watch for
Doses above 1g may cause loose stools. Take divided doses with meals. High-dose vitamin C increases urinary oxalate — relevant if prone to kidney stones.
