The best energy drink is the one that suits how you actually use it. For long days at a desk, on court or out on the course, that means a moderate dose of caffeine, very little sugar, and a can you can sip for an hour rather than finish in five minutes.
PÜRCHARGE is a still energy water made in the UK. Each 330ml can has 125mg of caffeine from green coffee, L-Theanine from green tea extract, enXtra®, rhodiola, Panax ginseng, electrolytes and nine vitamins. It is low in sugar and sweetened with stevia leaf.
Most energy drinks were designed around a fast, fizzy, sugary hit. This one was designed around the long middle of the day, which is where most of the work actually happens.
