Taking regular dietary supplements? Be careful

Thu, Aug 4, 2016

A new report highlights the dangers of dietary supplements.


Consumer Reports details how little the U.S. Food and Drug Administration regulates dietary supplement producers. That’s ultimately dangerous for users, the advocacy organization says.


The report identified 15 supplement ingredients to avoid for health reasons. They are:

  • Acenite
  • Caffeine powder
  • Chaparral
  • Comfrey
  • Germander
  • Greater celandine
  • Green tea extract powder
  • Kava
  • Lobelia
  • Methylsynephrine
  • Pennyroyal oil
  • Red yeast rice
  • Usnic acid
  • Yohimbe 

15 Supplement Ingredients to Always Avoid


Supplements Can Make You Sick


Here’s one example: Green tea extract powder can cause dizziness, ringing in the ears and reduced absorption of iron, Consumer Reports says. It exacerbates anemia and glaucoma, elevates blood pressure and heart rate, contributes to liver damage and can lead to death.


Many supplements also can interact negatively with prescription drugs.


“That’s why it’s a good idea to tell your physician what supplements you are taking or you plan to take,” said Dr. Lynn Wagner, an integrative medicine physician with BayCare Clinic in Green Bay, Wisconsin. She was not part of the Consumer Reports study. “Work with your physician to ensure your safety when taking any supplements.”
