Key Benefits Contains Green Tea Phytosome™ complex. Includes full-spectrum green tea extract. Dual-delivery catechin formulation. Caffeine-free green tea supplement. Research-backed ingredient technology. Natroceutics Green Tea Bioactive is a caffeine-free green tea supplement developed to deliver green tea catechins using a dual-material approach. Green tea naturally contains catechins, a group of plant compounds, but these are known to have low oral bioavailability. This formula combines Green Tea Phytosome™, which complexes catechins with phosphatidylcholine, with a full-spectrum green tea extract intended for release in the gut. The two forms are included to address different stages of digestion and absorption. The supplement is designed as a daily addition to the diet and offers a structured way to consume green tea compounds without caffeine. It is made using controlled extraction methods and research-backed ingredient technologies.
