claimHowever, these findings arise from heterogeneous evidence streams—including preclinical experiments, trials of surrogate risk markers, observational cohorts, and genetic analyses—and therefore differ substantially in their ability to support causal inference.

claimSuch heterogeneity provides a rationale for exploring individualized tea-consumption strategies, but current evidence is insufficient to support disease-specific tea selection or therapeutic dosing.

claimIn cultured human subcutaneous preadipocytes and adipocytes, a white-tea extract reduced triglyceride incorporation, increased glycerol release, and downregulated peroxisome proliferator-activated receptor γ (PPARγ), CCAAT/enhancer-binding protein α (C/EBPα), and sterol regulatory element-binding protein 1c (SREBP-1c), indicating inhibition of adipogenesis and stimulation of lipolysis [].

claimSuch studies remain valuable for identifying targets, but they should be interpreted as proof of biological possibility rather than evidence that ordinary tea consumption reproduces the same intracellular concentration.
