Summary

This study tested whether a daily probiotic supplement (heat-treated Lactiplantibacillus plantarum LM1004) could improve immune function in healthy adults aged 19 to 75. Over 8 weeks, 120 participants took either the probiotic or a placebo. Researchers measured natural killer cell activity and other immune markers to see if the supplement made a difference. The goal was to find a safe, easy way to support the immune system.
