The ingredients in detail
Seven ingredients, one goal: making your weight-loss routine as easy and enjoyable as possible. Here's what's inside every single-serve stick – and why the combination is so cleverly put together.*
Many products bet everything on a single “miracle ingredient”. The Wellaray® Slim Coffee Booster takes a different path: it combines 7 coordinated components – plant extracts, satiating fibres and L-carnitine – that support your goal from several angles at once.*
According to the manufacturer, all ingredients come from natural sources, with no artificial fillers and no harsh stimulants. The formula is taste-free, instantly soluble and designed for daily use.
Green coffee bean extract
Unroasted coffee beans are particularly rich in chlorogenic acid – a plant compound that has made green coffee a fixture of figure programmes for years. Chlorogenic acid is associated with influencing how carbohydrates from food are absorbed and with supporting an active metabolism. A welcome side effect: the extract delivers around 30 mg of natural caffeine per stick.*
Green tea extract
Green tea has been treasured in Asia for centuries – and is one of the world's most popular companions for figure and well-being today. The credit goes mainly to its catechins (including EGCG), which are associated with stimulated energy expenditure.*
L-Carnitine
L-carnitine is a compound made by your own body with one clearly defined job: it transports long-chain fatty acids into the mitochondria – your cells' “power plants” – where they are burned for energy. That's exactly why L-carnitine has been one of the most popular ingredients in sports and figure products for decades.*
Mulberry leaf extract
The mulberry leaf has a long tradition in Asian tea culture. Its active compounds – above all DNJ (1-deoxynojirimycin) – are associated with a more balanced blood sugar level after meals. And steadier blood sugar means, for many people, fewer craving attacks and less uncontrolled snacking.*
Resistant dextrin
This well-tolerated soluble fibre naturally slows down digestion and can therefore keep you feeling full for longer. At the same time it feeds your beneficial gut bacteria – a well-kept microbiome is considered an important basis for metabolism and well-being.*
Psyllium husk
Psyllium husks absorb liquid and gently expand in the stomach – creating a completely natural feeling of fullness without eating more. They also support regular, comfortable digestion. A proven classic of natural health.*
White kidney bean extract
The extract of the white kidney bean (Phaseolus vulgaris) is known as a natural “carb companion”: it is associated with influencing the enzymes that break down carbohydrates in the gut – so that fewer carbohydrates from food are absorbed.*
☕ Caffeine: gentle, not jittery
One stick contains around 30 mg of naturally occurring caffeine according to the manufacturer – considerably less than a regular cup of filter coffee. Together with your coffee, that makes for a pleasant, even start to the day without extra jitters.
✔ Recommended use
Stir 1 single-serve stick a day into a drink of your choice – ideally your morning coffee, hot or iced. Also dissolves in tea, smoothies or water. Do not exceed the recommended daily amount.
