Part 2 of 4: Supplementing for cycling performance?

In Part one of Supplementing for cycling performance? I wrote about what a lot us think about from time to time. Is that supplement Ad telling the truth and what does the FDA think about Dietary Supplements. In part two I will cover the very simple question “What is Supplementation” and “What are the risks of supplementation?” I will also post a new poll “Have you ever had a bad reaction to a supplement?”
