The seven listed ingredients
Every sachet contains the same seven ingredients. The exact amount of each one is printed on the label of your box.
| Ingredient | What it is |
|---|---|
| Green coffee bean extract | Extract of unroasted coffee beans. It is the source of the small amount of caffeine in each sachet – about 6 mg per sachet. |
| Green tea extract | Extract of the leaves of the tea plant, Camellia sinensis, before they are fermented into black tea. |
| L-carnitine | A compound made from amino acids. The body produces it, and it is also found in foods such as red meat and dairy. It is named on the front of the box. |
| Mulberry leaf extract | Extract of the leaves of the white mulberry tree, Morus alba, traditionally brewed as a tea in East Asia. |
| White kidney bean extract | Extract of the common white kidney bean, Phaseolus vulgaris, the same bean used in many tinned bean products. |
| Resistant dextrin | A soluble dietary fibre made from starch, often used to add fibre to drinks because it dissolves without thickening. |
| Psyllium husk | Fibre from the outer husk of Plantago ovata seeds. It absorbs water, which is why it is best taken with plenty of liquid. |
Caffeine
Wellaray states that each sachet contains around 6 mg of caffeine, coming from the green coffee bean extract. That is a small amount next to a typical mug of instant coffee (around 100 mg) or a filter coffee (around 140 mg).
Flavour and format
Each sachet holds 2 g of powder. It is flavourless and dissolves quickly in hot or cold drinks. A box contains 20 sachets – 20 days at one a day.
