Bacteria for the Brain

A young field studies psychobiotics — specific bacterial strains that seem to nudge mood, not just digestion.

No one should swap their psychiatric medication for a tub of yogurt — and no serious researcher claims otherwise.

But the direction is clear. Specific strains can reach the brain's chemistry through the gut, which means the right probiotic may one day sit alongside therapy and medication as a genuine helper. Not a replacement. A teammate.
