The effects of spirulina on allergic rhinitis
RCT (n=129)
→ Spirulina at 2 g/day for 6 months significantly improved nasal discharge, sneezing, nasal congestion, and itching compared to placebo (P < 0.001).
Clinical comparison of the efficacy of spirulina platensis and cetirizine for treatment of allergic rhinitis
RCT (n=53)
→ Spirulina (2 g/day) was more effective than cetirizine (10 mg/day) for improving rhinorrhea, nasal obstruction, and smell reduction, with superior improvements in sleep and daily activity scores.
Efficacy of Spirulina for Allergic Rhinitis
Systematic review (2 RCTs, n=215)
→ Systematic review of 2 RCTs concluded spirulina is effective for allergic rhinitis, though evidence quality is low due to small trial numbers. Both included trials favored spirulina over placebo or cetirizine.

Editorial notes
SacredBod's longer take on Spirulina (Allergy Dose) — context the structured blocks above don't capture.
What it is
Spirulina is a blue-green microalgae (Arthrospira platensis) cultivated in alkaline water. At doses of 2 g/day or higher, it functions as an immunomodulator rather than just a general wellness supplement, with specific evidence for reducing allergic rhinitis symptoms through cytokine modulation.
How it works
Spirulina modulates the Th1/Th2 immune balance by suppressing IL-4 production while enhancing IFN-gamma and IL-10. It also inhibits mast cell degranulation and reduces inflammatory mediator release. Clinical trials at 2 g/day show significant reductions in nasal discharge, sneezing, congestion, and itching compared to placebo-and in one trial, spirulina outperformed cetirizine for symptom improvement.
Who should consider it
Adults with seasonal or perennial allergic rhinitis seeking a food-based immunomodulator. Particularly suitable for vegans and those who prefer whole-food approaches over isolated compounds. Not the same as general spirulina wellness dosing (500 mg-1 g).
Who should avoid it
Avoid if you have a known allergy to algae or iodine sensitivity. Source quality matters-contaminated spirulina can contain heavy metals or microcystins. Not suitable for people with phenylketonuria (PKU) due to phenylalanine content. May interact with immunosuppressive drugs.
Dosing
- Typical: 2000 mg/day for allergy modulation
- Timing: Morning with breakfast
- With food: with-food
- Notes: The allergy-specific dose (2 g) is higher than general wellness dosing. Begin at 1 g and increase to 2 g over 1-2 weeks to assess tolerance. Powder form allows flexible dosing; tablets typically require 4-6 tablets to reach 2 g.
- Time of day: [“morning”]
- Time note: Morning dosing provides all-day immune modulation and aligns with typical pollen exposure patterns.
- Food timing: with-food
- Food note: Take with food to reduce the mild digestive upset some users experience at gram-level doses.
Stack
- Pairs well with: Quercetin and vitamin C add direct antihistamine and mast-cell stabilization that complements spirulina’s slower immunomodulatory effect. Butterbur provides rapid symptom relief while spirulina builds baseline tolerance.
- Avoid combining: Avoid combining with other strong immune modulators (e.g., medicinal mushrooms, astragalus) without monitoring immune response.
- M/E/S synergies: [‘quercetin’, ‘vitamin-c-liposomal’, ‘butterbur-petadolex’]
Evidence grade
- Grade: B+
- Note: Two RCTs with positive results, including one head-to-head against cetirizine favoring spirulina. The 2008 Turkish trial (n=129) is the largest. Evidence quality is limited by small total trial numbers and the 2020 Iranian trial’s short 2-month duration. Mechanism is well-characterized through Th1/Th2 modulation.
