Key takeaways
- The supplied product material lists green coffee bean extract, green tea extract, L-Carnitine, resistant dextrin, psyllium husk, white kidney bean extract and mulberry leaf extract.
- Two are soluble fibres (resistant dextrin and psyllium husk) — drink plenty of water alongside them.
- Green coffee and green tea extracts may contribute caffeine, in addition to the caffeine already in your coffee.
- The supplied material does not show individual ingredient quantities, so check the current pack and ask a health professional if suitability is uncertain.
What the supplied product material confirms
The material supplied for Slim Coffee Booster identifies it as a food supplement, lists seven ingredients and shows 20 sachets in each box. It also presents the product as a sachet to add to coffee.
The material available to us does not show the quantity of each ingredient, a total caffeine figure, a complete nutrition panel, manufacturing origin or independent testing certification. We do not fill those gaps with assumptions. Always check the current pack before use.

Three ingredient groups in the formula
A simple way to read the list is by ingredient type. Green coffee bean, green tea, white kidney bean and mulberry leaf are plant extracts. Resistant dextrin and psyllium husk are soluble fibres. L-Carnitine is an amino-acid derivative. Grouping the names helps explain the formula without implying that the combination guarantees weight loss.
What the ingredient list cannot tell you
An ingredient name alone does not reveal its dose, standardisation, total caffeine or how your body will respond. Those details matter when assessing any supplement. This is why the current pack and individual health advice take priority over marketing language.
Caffeine and fibre considerations
Green coffee bean extract and green tea extract can contribute caffeine. Your finished drink may also contain caffeine from the coffee itself. Because the supplied material does not state a total caffeine amount, people who are sensitive to caffeine should take extra care and discuss suitability with a doctor or pharmacist.
Resistant dextrin and psyllium husk are soluble fibres. Fibre should be taken with adequate fluid, and a sudden increase may not suit everyone. Our dedicated safety guide explains the practical warning signs and who should seek advice before use.
Label and suitability checks
Before using any supplement, check the current pack for the complete ingredient list, amounts per serve, allergen statement, directions, warnings and expiry details. Formulas and labels can change, so the pack in your hand is the final reference.
Do not use the page as personal medical advice. If you are pregnant or breastfeeding, under 18, sensitive to caffeine, taking prescription medicine, managing a medical condition or concerned about an allergy, ask a doctor or pharmacist whether the product is suitable for you.
