is a carotenoid found in high concentrations in tomatoes and has been suggested to have a number of health and disease prevention benefits. It exhibits robust
properties and has garnered a plethora of interest for its use as a preventative measure and possible treatment for cardiovascular disease, skin health, eye health, and prostate cancer (Lindshield et al., 2006). Epidemiological studies have associated reduced risk of prostate cancer with high tomato product consumption (Giovannucci et al., 2002;Etminan et al., 2004). Additionally lycopene ingestion and blood serum concentration have been negatively related to prostate cancer occurrence (Etminan et al., 2004).
powerful antioxidant capacity was once thought to be the main factor contributing to its protection from disease, as it has been shown to have 2 times more antioxidant capacity than beta-carotene and 10 times more than a-tocopherol (Di Mascio et al., 1989). In addition to antioxidant properties, it has recently been shown that supplementation results in high concentrations of
sequestered in areas of high androgen sensitivity, such as the prostate. This unique feature has been shown to locally modify androgen metabolism in normal prostates and prostatic tumors (Herzog et al., 2005;Siler et al., 2004). Based on these scientific data,
is advantageous for anyone looking for a supplement with high antioxidant capacity and its impact on overall health and wellbeing. Males will benefit greatly from the protective and supporting effects regular lycopene ingestion on prostate heath.
