What to do to avoid potentially dangerous supplements?

You should look for the "USP verified" mark that indicates that manufacturers have asked U.S. Pharmacopeia to verify the quality of their products.
You should look at FDA website www.fda.gov/food/dietarysupplements for alerts and avisories.
Lastly but not the least, do not forget to consult your doctors or pharmacists who can help you stay away from supplements that may not be neccessary or may even be harmful to your specific health conditions.
