Spirulina: This blue-green algae may reverse age-induced decreases in brain function, lower the extent of damage during a stroke, and decrease oxidative stress and inflammation, according to animal research.

Aplha-Lipic Acid: A slew of studies suggests aplha-lipoic acid safeguards mitochondria, delaying congnitive decline, while augmenting memory and learning.

DHA: The brain is made up of 60 percent fat, and DHA is the most abundant omega-3 fatty acid in the brain's cell membranes. Studies show it helps reduce inflammation, increase blood flow to the brain, and regenerate new brain cells.
