Question about creating a LLC?

Hi! I have a invented a great fitness product that has been met with lots of approval, and I would like to take it to market. I have a few questions, and would really enjoy your help. First, how can i protect myself from lawsuits? I have heard of having an LLC, but am a little confused about this. I am fine with my business getting sued and going bankrupt, but I don't want to lose all of my savings as well. Thank you!
