Which supplement is most commonly linked with memory and circulation?

• A. Garlic
• B. Echinacea
• C. Ginkgo
• D. St. John's Wort

Answer: (C)

Ginkgo biloba is the supplement most commonly linked with memory and circulation because it has a long history of use as a cognitive aid and is often marketed specifically to improve cerebral blood flow. The active components are thought to help dilate small brain vessels and provide antioxidant protection, which together are associated with better memory function and microcirculation. In contrast, garlic is mainly discussed in relation to cardiovascular risk factors such as cholesterol and blood pressure; echinacea is used for immune support; and St. John’s Wort is used for mood disorders and has many drug interactions. So the memory-and-circulation connection is most strongly tied to ginkgo.
