Formation of an LLC is the quickest and least painful (in the wallet). With this formation, you can sell. When it comes to the FDA, your best bet is to inquire with your Town Hall, perhaps a local University, or even someone who owns a restaurant or food business where they package food on premises. Most states do not allow creation and packaging within a household. Town Hall and/or a University can head you in a direction to an FDA approved facility for the creation of your product. If you go and have the FDA approve your product, it's gonna cost you a good amount of cash. Your best bet is to find a co-packer, have them create and bottle it for you, as they are responsible for it then, and are already FDA approved (make sure yourself). Selling it from your home shouldn't really be a problem, as long as you keep good records of your transactions. Since the product was previously packaged, there is no piercing of the corporate shield through your LLC in case of legal actions against you. Remember, your biggest cost will be legal fees in your endeavor, there's really not much you can do about that, and you should have a lawyer on retainer just in case. Insurance is a must as well, and depending which company insures you, the rates aren't really that bad. I wish you luck in your endeavor.
