FAQs

How much caffeine is in one serve?

Each 9 g serve has 100 mg of caffeine from tea leaf and/or coffee bean. For comparison, the AIS caffeine fact sheet lists about 60 mg in a 250 ml cup of instant coffee and about 80 mg in a cup of brewed coffee, so one serve is a little more than a typical cup.

Can I have more than one serve a day?

Two serves give 200 mg of caffeine. The AIS caffeine fact sheet notes that international health agencies generally consider up to 400 mg a day from all sources, and no more than 200 mg at one time, safe for healthy adults who are not pregnant. Count coffee, tea and energy drinks in that total.

Is it a pre-workout?

It can be used before exercise, but at 100 mg of caffeine per serve it is much lighter than high-stimulant pre-workouts, some of which contain 300 mg or more per scoop. The label also suggests it for mornings or afternoons. Read more in our caffeine guide.

Does it contain sugar?

Blue Raspberry has 0 g of sugars, 1 g of carbohydrate and 5 Calories per serve. It is sweetened with sucralose. Other flavours may differ slightly, so check the panel on your tub.
