The phytonutrients EGCG and resveratrol have a direct and indirect effect on your central nervous system, including having proneurogenic properties and improving cognitive function.
EGCG demonstrates the ability to enhance connectivity in the brain, lower cognitive impairment and reduce beta-amyloid accumulation associated with Alzheimer’s disease.
Resveratrol, found in grapes, berries and dark chocolate, has multiple health benefits, including improving blood flow in the brain, cognitive performance, learning and memory.
Both EGCG and resveratrol play a role in supporting your immune function. Resveratrol inhibits the growth of MERS-CoV in the lab and EGCG is a zinc ionophore, important in the fight against colds, flu and COVID-19.
