Ginkgo biloba The most helpful components of ginkgo are believed to be flavonoids, which have powerful antioxidant qualities, and terpenoids, which help improve circulation by dilating blood vessels and reducing the "stickiness" of platelets, thus improve circulation to the brain and revive brain power. Ginkgo biloba might help relieve anxiety. People with generalized anxiety disorder and adjustment disorder who took this specific extract had fewer anxiety symptoms than those who took placebo. Taking ginkgo leaf extract in combination with ginseng seems to improve memory in healthy people between the ages of 38 and 66.

Vitamin B12 is crucial for brain health, supporting nerve insulation (myelin), producing mood-regulating neurotransmitters (serotonin, dopamine), and aiding cognitive functions like focus and memory, with deficiency linked to fatigue, depression, and cognitive decline, though supplementation benefits vary and research continues, especially in non-deficient individuals.
