Summary

This completed study tested whether a daily fermented soy powder (Q CAN PLUS) could improve thinking skills, immune function, and response to the flu shot in healthy adults aged 65 and older. 62 participants took either the soy supplement or a placebo for 16 weeks. Researchers measured changes in blood markers of inflammation and immune activity, as well as cognitive test scores.
