Synopsis

Rating (out of 5): 3

Green tea antioxidants, particularly catechins like epigallocatechin gallate (EGCG), have been studied for their potential benefits in supporting prostate health. Several epidemiological and laboratory studies suggest that green tea consumption may be associated with a reduced risk of prostate cancer and may help support overall prostate health. The mechanisms proposed include antioxidant activity, inhibition of cell proliferation, induction of apoptosis (programmed cell death) in prostate cancer cells, and the modulation of androgen signaling pathways.

Meta-analyses and observational studies have found that men who consume higher amounts of green tea may have a lower risk of developing prostate cancer, especially in Asian populations where green tea consumption is common. Some clinical trials have explored the effect of green tea extracts on prostate-specific antigen (PSA) levels, a marker of prostate health, with mixed but generally promising results.

However, while laboratory and animal studies are robust, human clinical evidence is still emerging and not entirely consistent. Most human studies are small and of short duration, and the precise dosage or long-term effects of green tea antioxidants on prostate health are not fully established. Therefore, while there is a scientific rationale and some supporting evidence, more rigorous and large-scale clinical trials are needed to confirm these benefits.
