Take a probiotic with allergy-specific strains

What to Do

Take a daily probiotic containing Lactobacillus paracasei LP-33 or a multi-strain formula. Start 4-8 weeks before allergy season for best results.

Why It Works

A 2022 meta-analysis of 28 studies found probiotics improved at least one symptom of allergic rhinitis. L. paracasei LP-33 had the most consistently positive results across all five studies that tested it. Probiotics modulate Th1/Th2 immune balance and reduce pro-inflammatory cytokines.

Tips

• Strain specificity matters enormously — not all probiotics help allergies
• Effects are modest; best used as a complement to conventional treatment
• Multi-strain mixtures showed the best combined efficacy in network meta-analyses
• Results take weeks to manifest; this is not a quick fix
