Green tea extract supplements, lycopene supplements, and selenium supplements may help reduce the risk of certain cancers, such as prostate cancer and ovarian cancer. ConsumerLab.com's test results from our green tea review, lycopene review, and selenium review found that not all supplements deliver what they claim or meet other standards of quality. Because you can't "feel" a preventive therapy, you generally won't know if the supplement you take has problems.
In tests of green tea, lycopene and selenium, ConsumerLab.com found that 40% of green tea supplements and 40% of selenium supplements failed the tests! Specific problems identified in the new review of green tea, lycopene and selenium include:
- In our green tea review, we found a green tea supplement contaminated with lead and with fewer catechins (such as EGCG) than claimed. Another green tea extract supplement had 74% more caffeine than promised.
- Our selenium review revealed a selenium supplement that would not fully break apart in the expected 30 minute time period.
- A supplement promising a gram of fiber in each pill but weighing less than one-fifth of a gram -- making the claim impossible.
