Synopsis

Source of validity: Scientific
Rating (out of 5): 2

Green tea (Camellia sinensis) has been traditionally used in various cultures for its health-promoting properties, but its use specifically to support the glandular (endocrine) system is more recent and primarily based on emerging scientific evidence. The glandular system includes hormone-producing glands such as the thyroid, adrenal, and pancreas. Research has focused on green tea’s bioactive compounds, particularly catechins like epigallocatechin gallate (EGCG). Laboratory and animal studies suggest that EGCG may influence metabolic processes, glucose regulation, and fat oxidation, which are related to endocrine function. Some human studies indicate green tea can improve insulin sensitivity and glucose metabolism, potentially benefiting pancreatic health.

However, direct evidence for green tea supporting the overall glandular system remains limited. While green tea’s antioxidant and anti-inflammatory effects may offer indirect support to endocrine health, there is insufficient high-quality clinical research demonstrating a significant or direct effect on major glands (such as the thyroid or adrenal glands). Most studies are small or preliminary, and results are sometimes inconsistent. Thus, while there is some scientific rationale for green tea’s use in supporting metabolic aspects of the glandular system, the evidence is modest, and more research is needed to establish clear benefits.
