After studying supplements for over 15 years, I know which supplements work – and don’t work. I wrote this book so you will know what I know. I give you the unbiased truth on 119 vitamins, amino acids, herbs, minerals, proteins etc. Each supplement claim is put to the test. Does it work or doesn’t work. Over 900 clinical studies are included so you can see the proof yourself. You also learn about the side effects nobody else wants to talk about.
