Lycopene Overview

Written by FoundHealth.

Lycopene is a powerful antioxidant found in tomatoes and pink grapefruit. Like the better-known supplement beta-carotene , lycopene belongs to the family of chemicals known as carotenoids. As an antioxidant, it is about twice as powerful as beta-carotene.

Sources

Lycopene is not a necessary nutrient. However, like other substances found in fruits and vegetables, it may be very important for optimal health.

Tomatoes are the best source of lycopene. Happily, cooking doesn't destroy lycopene, so pizza sauce is just as good as a fresh tomato. In fact, some studies indicate that cooking tomatoes in oil may provide lycopene in a way that the body can use better, 1 although not all studies agree. 2 Lycopene is also found in watermelon, guava, and pink grapefruit. Synthetic lycopene is also available and appears to be as well absorbed as natural-source lycopene. 3

Therapeutic Dosages

The optimum dosage for lycopene has not been established, but the amount found helpful in studies generally fell in the range of 4 to 8 mg daily.

It has been suggested the lycopene is better absorbed when it is taken with fats such as olive oil, but one study failed to find any meaningful change in absorption. 4
