Summary
This study looks at whether nattokinase, a natural enzyme from fermented soy, can help people with early signs of metabolic syndrome and poor sleep. About 80 adults will take either nattokinase or a placebo for 12 weeks, then switch after a break. Researchers will check sleep quality, thinking skills, blood pressure, and gut bacteria to see if the supplement makes a difference.
