I am a fan of Special K nutritioon products and have followed a diet plan that included many of their food and drinks. I pucked up the Special K Protein shake after beginning a new workout and wanting to add extra protein to my diet. I chose the Special K brand because i am familiar with their other great tasting products and figured to give it a try. I purchased a few packs of these with a coupon while they were on sale so I got a good deal. They are tasty, unlike some other protein shakes and drinks, they are great for on the go or a quick "snack" during the day and they are filling. My only con to the Kelloggs Special K Protein shakes is that without a coupon or a sale, these are very pricey especially if you drink them everyday or even a few times a day. If the price of these came down a bit I would be more willing to purchase more of these. I still have recommended them to a few others who also use protein supplements.
