Unfortunately, many vitamin supplement makers capitalize on old myths that many people don't realize have been proven wrong. EGCG and green tea are frequently touted as weight loss aids, but the only study done showed that if you drank 4 cups of green tea daily, it would result in up to an 8 pound loss over the course of a year and it only worked with real green tea, not with supplements. One cup of green tea has about 25 to 30 mg of EGCG. But green tea is loaded with antioxidants and should be enjoyed anyway
Chromium is believed to be an essential trace mineral. One form, chromium picolinate, has been sold as a weight loss aid for many years. It is claimed to boost athletic performance, build muscle, and promote weight loss. The Federal Trade Commission have determined these claims to be deceptive.
While chromium may have health benefits, extensive clinical trials have shown that chromium does not have an effect on weight loss. Chromium can cause side effects in many people, including everything from stomach discomfort to genetic mutations in DNA. (according to Berkeley Wellness, University of California) Chromium may also interfere with other supplements or medications.
