In the UK, a drink can only be called low sugar if it has 2.5g of sugar or less per 100ml. Plenty of "natural" energy drinks don't make the cut, because fruit sugar still counts.
Every PÜRCHARGE flavour is under 1.7g of sugar per 100ml, from 3.8g per 330ml can. The sugar comes from a little fruit juice, and the rest of the sweetness comes from stevia leaf, not sucralose or aspartame.
Low sugar isn't low caffeine. Each can still has 125mg, so count it with your coffee.

What it does
Roughly a cup and a half of coffee, from the bean rather than a lab. Caffeine contributes to increased alertness and improved concentration. Here it never arrives alone, which is the whole point.
Did you knowGreen coffee beans are simply unroasted coffee. Roasting develops the flavour, not the caffeine.
-
What it does
Not a token dusting. Fifty to seventy-five percent of your daily reference intake in one can, with B3, B6 and B12 contributing to normal energy-yielding metabolism and B5 to normal mental performance.
Did you knowThe B group is water soluble, so the body cannot stockpile it. Whatever you do not use today, you need again tomorrow.
-
What it does
Potassium is one of the two electrolytes that decide whether water stays in you or passes straight through. Coconut water is one of the richest natural sources of it.
Did you knowHydration is not only about how much you drink. Without electrolytes a lot of it leaves as quickly as it arrived.
-
What it does
The sodium half of the equation, hand-harvested rather than refined, so the trace minerals survive. It is why the can hydrates during the session rather than only after it.
Did you knowIts grey tint comes from the mineral-rich clay of the salt beds. Refined white salt has had that washed out.

Questions·Straight answers
Low sugar energy drinks, clearly explained.

Not really. Sugar from fruit juice still counts as sugar. That's why some "natural" drinks aren't low sugar at all.
