What are the side effects of Bifidobacterium lactis?

Potential side effects include: Mild bloating and gas (usually transient), Generally very well tolerated.

What is Bifidobacterium lactis and how does it support immunity?

Bifidobacterium lactis (B. lactis) is a probiotic strain that naturally inhabits the human gut. Research suggests it may enhance innate immune responses, increase natural killer cell activity, and support mucosal immunity in the gastrointestinal tract.

What dosage of Bifidobacterium lactis has been studied?

Clinical studies have used B. lactis at doses ranging from 1 billion to 10 billion CFU per day. The strain B. lactis HN019 has been most extensively studied for immune outcomes, typically over 3 to 6 weeks.

What are the potential side effects of Bifidobacterium lactis?

B. lactis is generally well tolerated and considered safe for most adults. Some individuals may experience temporary bloating or gas when first starting supplementation. Immunocompromised individuals should consult a healthcare provider before use.

About

B. lactis enhances innate immunity by increasing phagocytic activity of polymorphonuclear cells and NK cell tumoricidal activity. It supports mucosal barrier function and modulates systemic cytokine profile toward balanced Th1/Th2 response. Meta-analyses in healthy elderly show enhanced NK cell activity and phagocytic capacity.

How It Works

Enhances innate immunity by increasing phagocytic activity of polymorphonuclear cells and NK cell tumoricidal activity; supports mucosal barrier function; modulates systemic cytokine profile toward balanced Th1/Th2 response.
