Using Slim Coffee Booster
What is Slim Coffee Booster?
It is a powdered food-supplement sachet made to be added to coffee. It is not a replacement coffee, meal replacement or medicine. Read our how it works guide for the full explanation.
How do I use it?
Follow the directions on the current pack. The supplied product material presents Slim Coffee Booster as a sachet added to coffee. For practical preparation information, see the detailed usage guide.
How long does one box last?
Each box contains 20 sachets. How long it lasts depends on the directions on your current pack and how consistently you use it.
Can I use it with hot, iced or decaf coffee?
The supplied material shows the sachet being added to coffee, but it does not give us enough information to promise the same mixing result in every hot, iced or decaf drink. Follow the current pack directions.
What should I do if I miss a day?
Do not double the next serve to make up for a missed day. Resume according to the directions on the current pack.
How should I store the sachets?
Follow the storage instructions on the current pack and keep it available as your final reference. Keep the product away from children.
Ingredients, caffeine and the label
What ingredients are listed?
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. See the ingredient-by-ingredient guide.
How much of each ingredient is in a sachet?
The supplied product material available to us names the seven ingredients but does not show their individual quantities. Check the current pack for the most complete information.
Does it contain caffeine?
Green coffee bean extract and green tea extract may contribute caffeine, in addition to any caffeine in your coffee. The supplied material does not state a total caffeine amount, so caffeine-sensitive people should take extra care.
What does it taste like?
Taste is personal, and the supplied product material does not give us enough verified information to promise a particular flavour, sweetness or texture. Your coffee and additions may also affect the finished drink.
Is it gluten free, sugar free or allergen free?
We cannot verify those claims from the supplied material. Check the complete ingredient, nutrition and allergen information on the current pack before use, especially if you have coeliac disease, an intolerance or an allergy.
Why are fibre ingredients included?
Resistant dextrin and psyllium husk are soluble fibres listed in the formula. Fibre should be taken with adequate fluid, and individual digestive tolerance varies.
Price, orders, delivery and refunds
How much does Slim Coffee Booster cost?
Current bundle prices are $49.99 for 1 box, $79.98 for 2 boxes and $89.97 for 3 boxes. Prices are in AUD and include GST. See the full price breakdown.
How much is shipping?
Shipping is $9.95 for one box and free for two or three boxes. Orders ship within Australia with tracking.
How long does delivery take?
Delivery time depends on the destination and carrier conditions. Any time shown is an estimate rather than a guarantee. Check the shipping page for the current metro, regional and remote estimates.
Is this a subscription?
No. Every order is a one-time purchase. There is no recurring billing and nothing to cancel.
Which payment methods can I use?
Checkout shows the payment methods currently available for your device and browser. Supported options may include major cards and compatible digital wallets; only the methods displayed at checkout can be selected.
Is checkout secure?
Payments are handled through Shopify's secure checkout. Slim Coffee Booster does not receive or store your full card number.
How do I track my order?
Use the tracking information sent for your order. If tracking has stopped updating or a parcel is marked delivered but has not arrived, use the Contact page and include your order reference.
What does the 30-day guarantee cover?
Contact us within 30 days of delivery if the product is not right for you. Opened product is permitted. Where a return is required, we provide instructions; approved refunds go to the original payment method. Change-of-mind return postage is the customer's responsibility. Read the complete refund policy.
What if my parcel is damaged, incomplete or incorrect?
Contact us within seven days of delivery with your order reference and a photo. We cover return costs for faulty, damaged or incorrect items, in line with the refund policy.
Safety and suitability
Who should not use it?
Do not use it if you are under 18, pregnant or breastfeeding. If you are sensitive to caffeine, take prescription medication, manage a medical condition or have allergy concerns, ask a doctor or pharmacist before use.
Is Slim Coffee Booster a medicine?
No. It is a food supplement, not a medicine. It is not intended to diagnose, treat, cure or prevent any disease, and it cannot guarantee weight loss.
Can it cause side effects?
Individual tolerance varies. Caffeine-containing extracts may not suit caffeine-sensitive people, and a change in fibre intake may affect digestion. Read the safety and side effects guide and stop using the product if it does not agree with you.
Can I use it with prescription medication or other supplements?
Ask your doctor or pharmacist first. They can consider your medicines, other supplements, caffeine intake and health history together; a general FAQ cannot assess personal interactions.
Will it work for me?
Results vary, and no food supplement can promise a number on the scale or a timeline. Slim Coffee Booster is intended to sit alongside balanced meals and regular movement, not replace them.
What should I check before my first sachet?
Read the current pack for the complete ingredients, quantities, allergen statement, directions, warnings, storage and expiry details. The pack in your hand is the final reference.
