Energy without the afternoon slump.

You don't need to eat it every day. It works best now and then, when you genuinely need energy: instead of a second coffee, before training, when there's no time for lunch. A case holds 24 bars – at four a week, that's roughly six weeks.

A case arrives with every batch – once a month – at the same price as a one-time purchase: no discounts, but real benefits. Your place in every batch is guaranteed, even when it sells out. Your price won't go up for as long as you're in the Club. You'll taste new flavours first. And we'll add a gift to your third delivery. Change flavour, move a delivery or cancel the Club at any time in your account, with no fees.

Only ORIGINAL: 80 mg per box (40 mg per bar) from guarana, roughly the same as one espresso. COCOA, COCONUT and PROTEIN contain no caffeine at all.

The coating is the only part of the bar we don't take straight from the field. We chose Felchlin of Switzerland because it makes chocolate the way we need it: sugar-free 100% cocoa mass from organic cocoa grown in Suhum, Ghana, which it buys directly from the growers. No chocolate flavouring, no compound coating. Cocoa beans and cocoa butter, nothing more. That's why gfBar costs more than bars coated in vegetable fat – and why it tastes different.

COCOA, COCONUT and PROTEIN are all caffeine-free; for children we recommend COCOA or COCONUT (or the JUNIOR case, which has both). COCONUT contains no caffeine or taurine, and there are no nuts in the recipe. It may, however, contain traces of nuts, so we don't recommend it for children with a nut allergy. ORIGINAL is not suitable for children, or for pregnant or breastfeeding women.

ORIGINAL contains Brazil nuts. COCONUT contains milk and soya. All varieties may contain traces of milk, hazelnuts, almonds, peanuts and other tree nuts. None of the varieties contain gluten.

Because one bar is a serving and the other is a spare. The box fits in a pocket or a bag – eat one mid-morning and the second waits for the afternoon slump. And if you give it to someone else, that's one more person who knows what gfBar is.

Our process for controlling temperature from the moment the blueberries are harvested to the finished bar – through drying, shipping, storage, production and chocolate coating. Heat takes more out of ingredients than anything else, so we keep it in check along the entire chain, to keep as much of what was in the blueberry in your gfBar as possible. It's a registered trade mark in the EU. Temper Protect® describes how we work; it makes no promises about your health.

We make gfBar once a month in small batches and dispatch it straight after production. Nothing sits in a warehouse. Orders for the next batch close on 8 November and are dispatched on 16–18 November. In the Czech Republic and Slovakia they usually arrive within two working days; elsewhere in Europe it takes a little longer. We only send parcels Monday to Wednesday, so the chocolate never spends a weekend in a depot. Until orders close you can change or cancel your order free of charge – just email help@gfbar.com and we'll refund you in full. This doesn't affect your statutory rights when buying online. If we have a few cases left over from the previous batch, we'll send them out earlier: Club members first, then in order of purchase, always with the production date.

Somewhere dry and out of direct sunlight, ideally below 20 °C. No fridge needed. In summer, don't leave the case in the car or on the balcony after delivery – we've watched the temperature all the way to your door; the last few metres are up to you.
