Supplements

From vitamins and minerals, to herbs, botanicals, probiotics, and more: these products are available nearly everywhere.

Over half of US adults report using supplements!

It’s hard to ignore the marketing claims insisting that there’s a supplement for everybody, whether you’re trying to address medical concerns, or just want to enhance your well-being.

Supplements appeal to our desire to choose for ourselves what we consume for health and wellness. In fact, most of us are making decisions about taking supplements on our own, rather than on the recommendation of a healthcare provider.

But an essential aspect of controlling your own healthcare is learning how to protect yourself against harmful products and potentially dangerous interactions between supplements and medications.

If you opt to take supplements of any kind, exercise your power of control by:

  • understanding what we know and don’t know about supplements, and how supplements are (not) regulated
  • getting your information from reliable, non-commercial sources
  • staying up-to-date on announcements regarding harmful products
  • avoiding harmful interactions by fully informing your healthcare provider about all the supplements you take
