I drink coffee in the morning, because I like it. I don't think that will change, but any other time during the day, Caffeinated water, which I assume you are referring to "Avitae Caffeinated Water", is the best thing to come along since sunshine itself. No more afternoon coffee or soda or an Energy drink! I can get hydrated and be more alert, productive, and focused anytime I want without calories, additives, or chemicals that I can't even pronounce. The simplicity of Avitae is elegant and it embodies the qualities of a natural product. Purified water and Natural Caffeine. Many people don't know that the caffeine in soda and energy drinks is synthetic, meaning it is made up in a lab somewhere. That freaked me out!
I also like that fact that you included the milligrams of caffeine you were inducing. What is nice about the Avitae product is that you have choices on the level of caffeine you want to consume at a given time. Heck, one 90mg and one 45mg gives you 135mgs or two 90mgs give you 180mg. Both with ZERO calories and only about $1.49 each. If you think about that 420 calories a day for the Double Shots, that is 153,300 calories a year. So, for $2.98 a day, you get the same or more caffeine with ZERO calories. I like those kinds of choices. I find myself utilizing the 45mg or the 90mg option all the time. Matter of fact, I like to have choices. It is very cool that I get to choose the caffeine level and I never have to worry about calories or other chemicals going into my body.
Bottom line and the answer to your question: Caffeinated water is an excellent choice and a very healthy alternative to many sources of caffeine. Avitae is also a very cool brand. I'm glad they actually thought of caffeinated water and actually made it come to life!
