Lycopene is a bright red pigment that is naturally found in the human liver, serum (blood), adrenal glands, lungs, prostate, colon, and skin at higher levels than other similar pigments. In animal studies, lycopene has been found to have antioxidant effects and may also block cancer cell growth. However, there is still controversy over whether it has these effects in humans.
Many studies suggest that eating lycopene-rich foods or having high lycopene levels in the body may be linked to reduced risk of cancer, heart disease, and age-related eye disorders. However, measures of lycopene intake have been based on eating tomatoes, not on the use of lycopene supplements. Since tomatoes also contain other nutrients, such as vitamin C and potassium, the potential benefits of lycopene alone are still unclear.
Lycopene deficiency is not considered a medical condition. There is a lack of evidence on whether increasing low lycopene levels may benefit health.
