Publisher's Summary

We all see the colorful and glistening protein supplements on gym and store shelves. Do these supplements actually work though, or are they just another fitness fad? Dietary supplements are not regulated by the FDA so it's up to die-hard fitness fanatics to prove if protein supplements actually work or not. Find out if protein may be your new solution from a personal trainer perspective. I am a certified personal trainer from the National Federation of Professional Trainers, certificate number 45582.
