Lycopene may be an important substance in maintaining prostate health. A recent clinical trial demonstrated that lycopene at a dose of 15 mg per day can significantly improve markers of prostate proliferation. In addition, the strong lipid antioxidant properties of lycopene make it particularly effective in maintaining healthy LDL oxidation and protecting against free radical activity on the arterial wall. Improved tomato extraction methods have given consumers access to supplements that contain greater concentrations of lycopene at lower prices.
