Summary
This study will give 180 healthy adults a daily probiotic supplement (Lactobacillus plantarum) for 1 or 6 months. Researchers will collect blood and stool samples and run online cognitive tests to see if the supplement changes gut bacteria, blood markers, or thinking skills. The goal is to learn more about how probiotics affect the body and mind, not to treat any disease.
