I'm addicted to Jamba Juice, but I always decline on their "free boost" offer. Yesterday, I decided to try their "energy boost." I'm just curious, are the boosts really just a few extra vitamins? I'm curious if things like the "immunity boost" (for when you're sick) or the "energy boost" are all that different from each other. Your thoughts? On a side note, I would like to point out that you haven't lived a full life until you've had a Jamba Juice Tahiti Green Tea.
