Kellogg’s Special K20 protein water is a diet supplement drink that offers assistance to dieters. The water helps dieters manage their weight by taking the edge off hunger in between meals. Consumers can choose between a variety of flavors including tropical blend, lemon twist, mixed berry and strawberry kiwi. The water is sweetened with a combination of sugar and calorie-free sucralose. The minimal amount of sugar in the water is believed to help curb cravings and urges that dieters often experience throughout the day.

Some reviews criticize the product for containing added sugar while being targeted to weight loss consumers. Special K20 adds five grams of both protein and fiber to the water in order to make the product diet friendly. The addition of protein and fiber in the water has been researched as weight loss agents. This research found that diets high in protein and fiber can assist in weight loss. The water is not touted as one of those currently popular energy drinks that give a powerful boost but instead, Kellogg’s Special K20 protein water is listed as providing energy, motivation, an increase in strength, stamina, and recovery time, while supporting good nutrition and diet. Kellogg’s describes this product as “a refreshing drink that will help you stay on track”.


Water, sugar, whey protein isolate, citric acid, natural and artificial flavor, phosperic acid, calcium lactate, calcium gluconate, sucralose, yellow #6.

Ready made, bottled diet drinks are becoming more and more popular all the time. They are convenient and are a great substitute for soda or plain water. The only thing we find unusual with this drink is that it does contain some calories. It may help you lose a few pounds if you stop drinking soda completely and drink this product instead but we recommend adding a thermogenic weight loss supplement to your diet to maximize weight loss.

It is a great item for losing weight I used this has my pick me up instead of coffee and I took off several pounds by just cutting my coffee intake back.

    I used the Special K2O Protein Water Mix (strawberry kiwi) to get some quick protein in after my workout–big mistake! It gave me instant heartburn, so badly in fact that the entire drive home was spent forcing back the VERY strong urge to vomit. It’s been 1.5 hours now since I drank the stuff, and my chest still hurts very badly, and feels like my throat is closing off. I’m assuming it’s the artificial sweetener, but whatever it was, it is NOT WORTH IT! especially since the product itself really doesn’t even taste very good at all.



    YOU may be allergic to the product. All In all you can’t bash on it and say it is a bad product. I actually use the same one and I have not had any problems with it. It curbs my appetite and In my opinion, it is very tasty. Definitely worth the $, which isn’t very pricy at all
