Slim coffee, without giving up the coffee you like

Booster sachet, not a replacement coffee
Swap-your-coffee products fail for a simple reason: people don't like the replacement. Slim Coffee Booster is a sachet you add to your usual coffee — instant, plunger, pods, or a long black. Follow the pack directions and judge the flavour with your preferred coffee and milk, as taste varies between people.
Why the format matters
A slim coffee that requires a new bean, a new brand and a new taste is one more thing to remember. A sachet slots into a routine you've already got, which is why it's easier to keep up for weeks rather than days.
It also means you're not locked into one brew method. Whether your kitchen has a plunger, a pod machine or just a kettle and instant granules, the sachet works the same way each time: tear, stir, drink.
Who tends to use it
People who reach for a slim coffee sachet are usually already coffee drinkers looking to get a bit more out of a cup they were going to make anyway. It suits mornings that don't have room for a shake or a supplement schedule, and it appeals to anyone who's tried a full slimming-coffee brand before and didn't like giving up their usual beans.
Who should skip it
What it tastes like
The sachet is designed to mix into black, milk-based or iced coffee. Flavour and texture depend on the coffee, milk and preparation method you choose.
What's in it
- Green coffee bean extract — a natural source of chlorogenic acid
- Green tea extract — traditionally used to support metabolism
- L-Carnitine — involved in how the body uses fat for energy
- Mulberry leaf extract — long used in traditional wellness practice
- Resistant dextrin and psyllium husk — soluble fibres
- White kidney bean extract
The full list with quantities and sourcing notes is on the ingredients page.
How to use it
One sachet a day, ideally in the morning. Stir into hot or iced coffee, drink plenty of water through the day, and keep eating balanced meals. Twenty sachets per box — enough for around three weeks at one a day.

Fitting it into a normal day
Because it's one sachet in one cup, it works whether that cup happens at home before work, at a café between meetings, or on the road. There's no need to carry a shaker bottle or plan around a blender — the only requirement is a hot or cold coffee to stir it into.
For people who've tried and abandoned more complicated routines, that simplicity is often the deciding factor. The habit that survives a busy week is usually the one with the fewest steps.
