In this video Casey, a performance dietician and researcher/published author, takes us through everything we need to know about the supplements industry. In future episodes, we will go over specific supplements--if they are good, how to use them, etc. If you missed it, we already hit Caffeine and L-Theanine, so check that out. We will also explore pharmaceuticals; medications like Adderall and more. Casey is a wealth of knowledge in the field of nutrition, I hope you enjoy it!
