Black Vitamin Energy Blueberry

There’s no official value on the can for caffeine content, hence I’ve guessed it at being as low as possible. This is branded as being a health drink, containing natural pick-me-ups such as guarana, magnesium, vitamin B6 and others. It tastes okay too so far as health-branded drinks go, but that’ll probably be because of all the sugar (not so healthy after all!).
