Could a simple supplement slow Alzheimer's? new trial aims to find out
NCT ID NCT07062198
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study tests whether a combination of four natural substances (CMA2) can improve brain function in people with Alzheimer's disease. About 845 adults aged 50 and older will take either the supplement or a placebo twice daily for 26 weeks. Researchers will measure changes in memory and thinking skills using standard tests to see if the supplement slows the disease's progression.
