Rating (out of 5): 2

Green tea (Camellia sinensis) has been studied for its potential benefits in supporting prostate health, primarily due to its rich content of polyphenols, particularly epigallocatechin-3-gallate (EGCG). Several laboratory and animal studies have suggested that green tea polyphenols may inhibit the growth of prostate cancer cells, reduce inflammation, and modulate hormone activity related to prostate health. A number of epidemiological studies have observed a correlation between high green tea consumption and a lower risk of developing prostate cancer, especially in East Asian populations where green tea is widely consumed.

However, clinical evidence in humans remains limited and somewhat inconsistent. Some small randomized controlled trials have found that green tea or its extracts may reduce the progression of prostate cancer in men with high-grade prostatic intraepithelial neoplasia, a potential precursor to prostate cancer. Other trials have failed to find a significant benefit. To date, the evidence base is not strong enough to make definitive recommendations regarding green tea for prostate health, but the biological plausibility and preliminary human data provide some rationale for its use.

In summary, while traditional use specifically for prostate support is not well documented, the scientific literature provides some, though not robust, support for green tea’s potential role in supporting prostate health, meriting a modest evidence rating.
