Probiotics

Probiotics are live beneficial bacteria that support the gut microbiome — a complex ecosystem that influences digestion, immunity, mood, and even body composition.

The Gut-Immune Connection

Approximately 70% of your immune system resides in the gut. A healthy microbiome trains immune cells to respond appropriately to threats while preventing autoimmune overreaction. Specific strains like Lactobacillus rhamnosus and Bifidobacterium lactis have strong evidence for immune support.

Beyond Digestion

The gut-brain axis means your microbiome directly influences mood and cognition. Certain probiotic strains (called psychobiotics) produce neurotransmitters like serotonin and GABA, contributing to mental well-being.

Choosing the Right Probiotic

Look for multi-strain formulas with clinically studied strains, third-party testing, and guaranteed CFU count at expiration (not just at manufacture). The best probiotics include both Lactobacillus and Bifidobacterium species.
