Are Supplements Needed?

I'm not an expert in this field but the information I'm going to provide is from some of the best in the industry.  I recently attended and spoke at the Smarter Team Training Conference in Baltimore and heard Jose Antonio speak for the third time.  I never miss a chance to hear him speak and also heard Michelle Rockwell for the first time.  Our society is filled with people trying to make money who really don't care if the products work or not they just want your money.  Here is what I took from both Jose and Michelle this past weekend.  I'll be happy to write more on this from their research but would love to get your thoughts first.  What do your guys think?

1.  Your most important meal is breakfast?
2.  Creatine or Coca Cola which one is worse?  What is your answer? 
3.  BCAA are important and supplements can help with this?
4.  Best protein post workout is whey?
5.  Casein is best used before you go to bed?
6.  If your a salty sweater what can you do to help?
7.  Beta Aline can help performance?
8.  Caffeine is bad for you?

These were just a few topics they discussed.  I've been asking my clients and athletes these same questions and was shocked by the answers I got.  I look forward to hearing your responses.  If you care to cheat in a good way check this site before you answer.
