I'm trying to phase out espresso, and my sister recommended that I try FRS healthy energy. I drank some before a workout because I had already been glutened a few hours before so I figured I may as well just give it a go. It was great (the peach mango concentrate) and now I want to start drinking it but I can't figure out if it's safe. I've tried calling the phone number on the website and never get an answer. I know some of the ingredients are suspect, but not officially on the unsafe list. Has anyone had luck contacting FRS or used this stuff without a reaction?
