Most people feel it within about 10 minutes. The caffeine absorbs straight through the lining of your cheek as you chew, so it gets to work faster than a coffee or a pill.

Three things. Speed: under 10 minutes versus roughly forty-five for a coffee. Control: each piece is an exact 20mg, so you set the dose instead of guessing at a cup. And it is calmer, because the L-theanine takes the edge off the caffeine. No sugar, no liquid, no crash.

Start with one or two. Two pieces is 40mg, about half a flat white. Across a whole day four pieces is roughly one coffee's worth of caffeine, spread out and without the crash.

Watermelon, sweetened with xylitol. Sugar-free, vegan and gluten-free. It chews like normal gum, the flavour just fades faster than the focus.

Caffeine sticks around for five to six hours, so it is the same rule as coffee: chew it earlier in the day and ease off through the afternoon if you are sensitive. It is not designed as an all-nighter.

It is caffeine and L-theanine at modest doses, the same as a cup of coffee with a calming amino acid. If you are on medication, pregnant, or sensitive to caffeine, check with your GP before using it.
