Impact
Score:
4.5
Justification:
Provides targeted antioxidant and metabolic benefits, but lacks strong longevity trial data.

Score:
6.5
Justification:
Strong observational data and human trials for metabolic endpoints, but limited longevity RCTs.
Safety
Score:
3.8
Justification:
Generally safe, but high doses are linked to potential liver toxicity.
Flags
- High doses (>800 mg EGCG/day) are associated with risk of liver injury.
- May reduce the absorption of iron and folic acid.
- Can interact with certain medications, including blood thinners and some heart medications.
- Best taken with food to minimize potential for stomach upset.
Verdict
A useful antioxidant, but mind the dose to avoid liver risk.
