This is a concentrated extract of green tea leaves, standardized for consistent amounts of EGCG and other catechins. Unlike brewed tea, the extract delivers a higher, more predictable dose of polyphenols in a capsule or tablet.
People take it mainly to support metabolic rate and for the caffeine-driven energy and focus it provides. The catechins, especially EGCG, also offer antioxidant support. The standardized form gives you a reliable, high dose without drinking several cups of tea.
Take it with meals to lower the chance of stomach upset. High-dose extracts can affect the liver, so careful dosing matters. This supplement may also interact with certain medications.
