Green tea catechins, especially EGCG, are associated with improved vascular function and improved lipid, blood pressure, and glucose markers when taken regularly.
Tea's L-theanine can reduce stress and anxiety and with caffeine can smooth out alertness and support calm focus for tasks.
Green tea polyphenols show antibacterial and anti‑inflammatory activity against oral pathogens supporting lower plaque and gingival inflammation and fresher breath.
EGCG and related catechins provide antioxidant effects that support endothelial health and may help counter oxidative stress.
A meta‑analysis of green tea extract reports modest reductions in body mass, body fat percentage, and oxidative stress markers, suggesting small but significant support for weight goals.
Steep 2–3 minutes at 70–80°C to avoid bitterness and preserve catechins; aim for 2–4 cups daily if tolerated and avoid late‑evening cups if sensitive to caffeine. (Disclaimer: Not medical advice.)
