Carotenoids, particularly lycopene, have been investigated for their role in supporting prostate health. The most notable scientific evidence relates to lycopene, a carotenoid abundant in tomatoes and other red fruits. Several epidemiological studies have found an association between higher dietary intake of lycopene and a reduced risk of prostate cancer. For example, a meta-analysis published in Prostate Cancer and Prostatic Diseases (2015) found a modest inverse association between lycopene intake and prostate cancer risk. Proposed mechanisms include antioxidant activity, inhibition of cancer cell proliferation, and modulation of androgen metabolism.

However, it is important to note that while observational studies suggest a potential protective effect, randomized controlled trials (RCTs) have provided mixed results. Some RCTs show no significant benefit of carotenoid supplementation for prostate-specific antigen (PSA) levels or prostate cancer progression. As such, while there is scientific interest and some supporting evidence, the overall strength of the evidence is moderate, and carotenoids are not considered a primary or standalone therapy for prostate health.

In summary, the use of carotenoids, especially lycopene, for prostate support is justified by moderate scientific evidence suggesting possible benefits, but further high-quality research is needed to confirm their efficacy.
