I drink a lot of water during the day and I like to add calorie-free flavoring quite often. I've tried many of these types of products that come in a squeeze bottle and you add the flavor to the water to your taste liking. Unfortunately, with this brand, although it says the flavors are 'natural', they do not taste like the flavor on the label. The blueberry acai simply tasted sweet with no distinct bluberry or acai flavor. Furthermore, this is a 'low calorie' and not zero calorie product, where it's approximately 5 cal/2mL. Well I added just 2mL to 250mL of water and you couldn't even taste the flavor. So it could potentially become a higher calorie beverage depending on how much you add.

Overall, I wouldn't recommend this product and there are better ones out there.
