How to execute a shortcode?

Well, as Christopher Davis mentioned – do_shortcode works fine with extra stuff included, so I decided to reset my server and echo do_shortcode(get_option('my_option')); started to work perfectly.

So I guess the answer has always been here, execute shortcodes with do_shortcode.
