Green Tea Extract and Prostate Cancer

A new study, funded by the National Institutes of Health, showed that fewer men with pre-cancerous lesions developed prostate cancer if given a daily green tea extract supplement, although the results were not statistically significant due, in part, to the small size of the study. However, a somewhat similar study found a significant benefit. Learn more about these studies, and see our test results for green tea supplements, teas, and drinks, in the Green Tea Review >>

Niacin Concern Stops Cardiovascular Study

A clinical trial using high dose niacin (vitamin B3) was recently stopped by the National Institutes of Health due to lack of benefit and a small increase in strokes. Patients in the study had cardiovascular disease and were already taking a statin drug to keep LDL ("bad") cholesterol levels low. The addition of high dose niacin was intended to increase HDL ("good") cholesterol, reduce elevated triglycerides, and, most importantly, reduce the risk of heart attacks and stoke. For more information, including the amount and type of niacin used in the study and additional information about niacin and niacin supplements, see the B Vitamin Supplements ReviewMore >>
