Crisp, Refreshing, and a Family Favorite
Flavor Name: Kiwi Strawberry, Size: 16.9 Fl Oz (Pack of 12)
Propel Kiwi Strawberry is one of our favorites. It’s crisp, refreshing, and has just the right amount of flavor without being overpowering. The kiwi strawberry taste is especially enjoyable and makes it easy to drink throughout the day. We also like that it’s zero calorie and includes electrolytes and vitamins, making it a great option for staying hydrated during workouts or busy days. Overall, a consistently refreshing drink that we always keep stocked in the house.

Excellent product. But I thought they were expensive.
Flavor Name: Kiwi Strawberry, Size: 16.9 Fl Oz (Pack of 12)
This is a great product, great ingredients, excellent taste, sugar-free. My friend a actually came over and I think he drink most of them or took them home to his wife. Didn't last long and I thought they were pricey.

Great tasting Propel Water
Flavor Name: Kiwi Strawberry, Size: 16.9 Fl Oz (Pack of 12)
Great-tasting and refreshing Propel is one of my to go to drinks when I want something flavorful without being overly heavy like soda. The flavors are crisp and not too sweet, and its nice bonus knowing there are added vitamins. Perfect for on-the-go or after workout. I keep coming back to it.

Good beverage choice to mix your colonoscopy prep powder in.
Flavor Name: Kiwi Strawberry, Size: 16.9 Fl Oz (Pack of 12)
In preparation for a colonoscopy I was allowed to mix the required prep powder in any flavored water beverage that replenishes electrolytes as long as the color was clear. I dislike water and am not good at drinking the daily minimum requirement. I had to find something I could tolerate especially with my having to drink 64 ounces in a matter of a few hours. So I started my Amazon search and based on the reviews, I purchased both the Propel Strawberry-Kiwi and the Melon flavors. I was taking a chance that at least one of the two flavors would work for me. The Strawberry-Kiwi albeit on the sweet side surprisingly tasted good after I added a ton of ice and made slushes. I really didn’t taste the Kiwi but the strawberry came through. The melon was less sweet but I did not get a real taste of melon flavor, just a hint. Since I only needed 64 ounces and each bottle is 16 oz, I only had to use 4 of the 24 bottles I purchased leaving me with 20. I’m going to continue making slushes but plan on adding fresh strawberries and melon to the mix and this way hopefully drink more while getting electrolytes. One Amazon review I read was by a couple who drank Propel daily and really felt sluggish if they skipped a day. I am hoping that by the end of consuming 20 bottles, I will also see a difference in my energy levels. The cost of Propel was extremely reasonable compared to like brands that in my opinion weren’t any different except for price. Even though Propel is sugar free, it does contain sucralose. As a I diabetic, I am not supposed to have any sugar substitutes other than stevia, but since sucralose is not one of the primary ingredients, and pretty far down the ingredient list, those 64 ounces I drank had a minimal (if any) effect on my blood sugar.
