PRODUCT REVIEW: Pocari Sweat

I admit I haven't heard about Pocari Sweat until it was offered to me for review. Living under a rock has its disadvantages- haha.

I didn't really know what Pocari Sweat is until the bottles were given to me. The first thing that comes to mind was- Energy Drink. However, I was corrected that it was an Ion Supply Drink. A what? I am familiar with alkaline drink but an ion drink is quite new to me.
