The gut microbiome plays a key role in immune system regulation. Probiotics may help support a healthy balance of gut bacteria, which is being studied for its potential effects on immune responses to allergens.*

- Strain Matters: Specific strains like Lactobacillus and Bifidobacterium are most studied for immune support.*
- Emerging Research: Some probiotic strains have been studied for supporting comfort during seasonal allergy season, although results vary between strains.*
- Best Used With: A diverse diet rich in fiber and fermented foods.*
How Probiotics May Support Immune Balance
Probiotics interact with the gut lining and immune cells, helping support communication between the gut microbiome and the immune system, which may contribute to a balanced immune response.*

Practical Strategies
• Choose multi-strain probiotics with clearly identified strains (Lactobacillus and Bifidobacterium species) and CFU count.
• Take consistently for at least 4–8 weeks to assess effects.
• Combine with a high-fiber diet and fermented foods for best microbiome support.*
Safety & Considerations
Probiotics are generally safe for most people. Those with compromised immune systems or serious medical conditions should consult their healthcare provider before starting.
