Lycopene

Lycopene is a naturally occurring carotenoid pigment and a powerful antioxidant responsible for the red color in tomatoes, watermelons, and pink grapefruits. Chemically, it is a tetraterpene that is highly lipophilic (fat-soluble), meaning it is best absorbed when consumed with fats. Unlike beta-carotene, lycopene is not converted into vitamin A by the body, but it is one of the most effective compounds for quenching singlet oxygen and protecting cells from oxidative damage.

Lycopene works as a primary scavenger of reactive oxygen species (ROS), protecting cellular membranes and DNA from oxidative stress. It modulates the inflammatory response by inhibiting pro-inflammatory cytokines like TNF-alpha and IL-6. In the skin, lycopene reduces the production of matrix metalloproteinases (MMPs) that degrade collagen in response to UV radiation. Additionally, research suggests it can inhibit the IGF-1 signaling pathway, which is linked to tumor progression, particularly in the prostate, and it improves endothelial function by preventing the oxidation of LDL cholesterol.

Research typically suggests a daily dose of 10 to 30 mg for general health benefits, while higher doses up to 75 mg have been evaluated for safety. It is highly recommended to take lycopene with a source of dietary fat (e.g., olive oil) to maximize absorption. Natural tomato-derived supplements are generally superior to synthetic ones due to the presence of complementary phytonutrients like phytoene and phytofluene. Caution is advised for those on anticoagulant medications, and supplementation should be discontinued 2 weeks before surgery. Evidence from the PREDIMED study (2025) indicates that dietary intakes above 4.9 mg/day show significant protective associations for prostate health in men at high cardiovascular risk.
