| Use | Evidence | Details |
|---|---|---|
| Heart & blood vessels | 🟡 Some evidence (small human studies) | In randomised trials, mostly of green tea extract supplements rather than the drink, green tea reduced total and LDL cholesterol to a small extent but did not change HDL cholesterol or triglycerides[1]. Green tea drinking has been linked to a lower risk of coronary heart disease in Asian but not Western populations[1]. |
| Brain & focus | 🟠 Early evidence (lab or animal studies only) | A 2025 meta-analysis of randomised trials in healthy adults found that L-theanine plus caffeine (both found in tea) gave small-to-moderate short-term improvements in attention and mood in the first two hours, with much uncertainty; more research with tea itself is needed. Some authors worked for a tea company[2]. |
| Energy | 🔵 Traditional use (not scientifically confirmed) | The EU herbal committee recognises green tea for relief of fatigue and a feeling of weakness as a traditional use in adults; it is not recommended under 18[3]. |
