Collection: Gut–Immune Connection

• Probiotics (Lactobacillus, Bifidobacterium) — support gut barrier function and immune signaling.
• Prebiotic fibers (inulin, FOS) — feed beneficial bacteria and promote microbiome diversity.
• Vitamin D3 — critical for immune regulation and gut barrier integrity.
• Zinc — contributes to immune resilience and tissue repair.
• Glutamine — amino acid that helps maintain intestinal lining health.
• Postbiotics — bioactive compounds produced by probiotics that influence immune balance.

• Strengthens the gut barrier to reduce unwanted immune triggers.
• Supports microbiome diversity with probiotics and prebiotics.
• Encourages immune balance through gut–immune signaling pathways.
• Promotes resilience year-round with nutrients like vitamin D and zinc.

1. Probiotics are supported by clinical studies for enhancing immune responses and reducing frequency of seasonal challenges.
2. Prebiotic fibers like inulin improve growth of beneficial bacteria and strengthen gut–immune signaling.
3. Glutamine supplementation has been shown to support intestinal barrier integrity and immune recovery.
4. Vitamin D3 is widely recognized for its dual role in bone health and immune regulation, including gut barrier function.

Notes: Evidence reflects ingredients, not specific Habity products. Effects vary depending on strain, dose, and baseline gut health.
