QUICK ANSWER

What is Multi-Strain Probiotic?

A diverse, multi-strain probiotic supplements the trillions of beneficial bacteria that line your digestive tract, collectively known as the gut microbiome. The microbiome influences immune function (70% of immune cells live in or around the gut), neurotransmitter production (90% of serotonin is made in the gut), and digestion itself. The best probiotic supplements contain 10 or more clinically-studied strains, deliver at least 25 billion CFU per dose, and use delayed-release capsules to protect bacteria from stomach acid. Garden of Life's Mood-specific formula includes strains studied for the gut-brain axis. Standard dose is one capsule daily; benefits typically emerge within 2-4 weeks.

WHY IT MATTERS

Supports digestive balance, immune signalling, and the gut-brain axis that influences mood and cognition.
