health, CVD, cancer and a number of other health concerns. Studies with lycopene from tomatoes
appear to show some benefit. Not sure if extensive studies with lycopene supplementation is conclusive tho'.
I do not believe that there is any know toxicity with high lycopene intake. However, excessive levels of lycopene and carotenes (such as beta-carotene), can cause yellowing (or orange-ing) of the skin -- this condition, however, is considered harmless. Some years back, I worked with a woman who drank about 2 liters (1/2 gallon) of carrot juice daily. After several months, the yellowing effect became noticeable.
As I mentioned in post #16, it is the AOA
that suggests that a beneficial daily intake of lutein should be about 10 mg/day and a daily intake of zeaxanthin should be about 2 mg/day. Lutein and the other carotenoids is considered nontoxic and well tolerated even in high doses. High intakes for 6 months to several years has yet to show any health risk. However, it is not known if several decades of high intake might have a downside. Best to get carotenoids from food sources and, if deemed necessary, take a decent supplement 3x/week.
