So you’re taking all the popular supplements—great!

But are they really helping? Is your health actually improving? Or could these supplements be harming you?

In The Truth About Dietary Supplements, you’ll learn:

A few basic facts about dietary supplements―Who makes them? Who sells them? Who is regulating them?
Why we may need to take supplements
The science behind supplements, both real and contrived
The role the media plays in our education about dietary supplements
How to assess what you truly need and assure the quality of the supplements you take
What to ask your healthcare provider to ensure you’re making the right choices

Taking dietary supplements can be good for us―when we need them. But many are unnecessary, and some producers make outsized claims while using suspect means of production.

This book does not advocate against supplement use. It’s a call for clarity and sanity on the subject to prevent misuse.

Mahtab Jafari, Professor of Pharmaceutical Sciences at UC Irvine, has distilled decades of clinical experience and laboratory research in her one-of-a-kind guide. The Truth About Dietary Supplements: An Evidence-Based Guide to a Safe Medicine Cabinet provides insight into this largely unregulated industry and empowers you to avoid getting swindled in your pursuit of good health.

Maybe it started quite simply. A multivitamin to keep the reserve tanks full. Then a tincture or tablet to improve sleep, boost energy, or gain an edge. Maybe an appetite suppressant to help shed that last ten pounds.

And now you find yourself with an expensive habit and a medicine cabinet filled to the brim with magic bullets that leave you feeling no better than before you started―or maybe even worse.

It doesn’t have to be this way!

This thorough guide also contains a robust appendix about the scientific evidence on dietary supplements and COVID-19 to help you navigate this new minefield of misinformation.

Stop wasting money on pills and potions that are useless, or even dangerous!
