Introduction
Lycopene is a compound found in tomato and grapefruit. It has been used as an antioxidant to slow damage to cells. Lycopene has also been used to lower blood pressure and fight off cancer cells. Lycopene can be taken as a pill or powder.
Dosages
6 to 15 milligrams daily
What Research Shows
Likely Effective
- Cardiovascular disease —likely to lower risk A1, A2
- High blood pressure —likely to lower blood pressure B1
- High cholesterol —likely to lower LDL (“bad”) cholesterol C1
- Ovarian cancer —likely to lower risk E1
Unlikely to Be Effective
- Preeclampsia —unlikely to prevent preeclampsia F1
Not Enough Data to Assess
- Leukoplakia D1
- Prostate cancer prevention G1-G3

Safety Notes
It is likely safe to take lycopene in small doses for a short time, but digestive upset is possible. Not enough studies have been done to say whether it is safe to take for a long period. Women who are pregnant or breastfeeding should limit their intake of lycopene.
Interactions
Talk to your doctor about any supplements or therapy you would like to use. Some can interfere with treatment or make conditions worse.
