Some Supplements May Nudge Memory Scores in People With Alzheimer's

Key Insight

This review suggests certain supplements may offer small memory benefits in people with cognitive decline.


Researchers pooled dozens of trials to see which supplements help thinking in people with Alzheimer's or mild memory loss. A few, like phosphatidylserine, spirulina, B vitamins, and a probiotic-selenium combo, showed small improvements on one memory test. But none helped on a second, more detailed test. So the wins are modest and depend heavily on how you measure them.
