Green tea is widely recognized for supporting longevity and healthy aging with regular consumption. Green tea is high in bioactive polyphenols, such as the natural catechin known as ECGC. These polyphenols have many targets within the body, with strong clinical research to support both cardiovascular health and a healthy inflammation response, two key indicators of longevity and healthy aging. Recent clinical studies have shown that polyphenols, such as ECGC, are capable of crossing the blood-brain barrier, providing neuroprotective effects that help with cognition during aging. Additionally, unlike synthetic versions, the natural caffeine from green tea delivers a slow, metered release of caffeine, and has natural synergistic ingredients such as L-theanine that counteract “jittters” or anxious feelings associated with caffeine intake. Caffeine stimulates the release of neurotransmitters and has been shown to aid in improved energy levels, cognition, focus, and reaction time during the presence of stress.
