What to know

Widely sold for memory, but large trials found no meaningful benefit for preventing cognitive decline. Acts as a blood thinner, which is the bigger practical concern.

Interactions & cautions

  • Thins blood — real bleeding risk with warfarin/aspirin and surgery.

Do you actually need it?

Little proven cognitive benefit; mind the bleeding risk.
