How to use Slim Coffee Booster - your morning ritual
Slim Coffee Booster is designed to slot smoothly into your existing morning coffee ritual. Here is the simple daily routine our editorial team recommends for consistent use as part of a balanced lifestyle.
Wake & warm up
Begin your morning with a full glass of water, then boil the kettle. Proper hydration supports normal metabolic processes throughout the day.
Dissolve one sachet
Empty one Slim Coffee Booster sachet into your mug. Pour 200 ml of hot (not boiling) water and stir for 20 seconds until fully dissolved. Do not exceed one sachet per day.
Enjoy with breakfast
Sip alongside a nutritious breakfast. The green tea extract and Vitamin B6 in the formula contribute to normal energy-yielding metabolism as part of a varied, balanced diet.
Maintain the habit
Consistent daily use as part of a healthy routine supports the best experience. One box provides a 30-day supply at one sachet per day.
The mechanism - from botanical extract to everyday support
Slim Coffee Booster brings together botanical extracts from Australia, South America, Asia and Africa. Here is how the key ingredients work together as part of a balanced lifestyle.
Botanical extracts
Green coffee bean (chlorogenic acids), guarana (natural source of caffeine) and green tea (EGCG) are standardised plant extracts traditionally used in everyday wellness routines across multiple cultures.
Metabolic support
Vitamin B6 contributes to normal protein and glycogen metabolism. Chromium contributes to normal macronutrient metabolism and to the maintenance of normal blood glucose levels - both EFSA-recognised nutrient functions.
Everyday energy
As part of a varied diet and active lifestyle, the formula supports your morning energy routine. Green tea extract contributes to the maintenance of normal body weight as part of a healthy lifestyle.
The above describes nutrient-level structure/function relationships as recognised by EFSA. These are not claims that Slim Coffee Booster treats, cures or prevents any disease. Individual results vary. Food supplement - not a medicine.
Green coffee bean extract supplement & botanical gallery
Each serving of Slim Coffee Booster delivers a precise blend of standardised plant extracts and micronutrients. Below is our ingredient spotlight - with EFSA-aligned nutrient function notes per ingredient.
Green Coffee Bean (Coffea arabica)
Standardised for chlorogenic acids. Traditionally used as part of everyday wellness routines. Green tea extract and related botanical compounds are also studied for their role in everyday energy-yielding metabolism.
Nutrient note: Green coffee bean is traditionally used; Vitamin B6 in the formula contributes to normal energy-yielding metabolism (EFSA).
Guarana (Paullinia cupana)
A traditional South American botanical and natural source of caffeine. Traditionally used to support alertness as part of a morning wellness ritual.
Nutrient note: Caffeine from guarana contributes to increased alertness and attention (EFSA-recognised for caffeine).
Green Tea (Camellia sinensis)
Providing EGCG (epigallocatechin gallate). Green tea extract has a long tradition of use in Asian wellness practices and contributes to the maintenance of normal body weight as part of a healthy lifestyle.
Nutrient note: Green tea extract contributes to maintenance of normal body weight as part of a varied diet and healthy lifestyle.
Vitamin B6 & Chromium
Two key micronutrients rounding out the formula. Vitamin B6 contributes to normal protein and glycogen metabolism. Chromium contributes to normal macronutrient metabolism and to the maintenance of normal blood glucose levels.
Nutrient notes: B vitamin supplement energy metabolism (EFSA); Chromium - normal macronutrient metabolism and normal blood glucose (EFSA).
For an active everyday lifestyle
Slim Coffee Booster is formulated to complement your existing routine - not to replace a varied diet or regular physical activity. The formula draws on botanical traditions from Australia, South America, Asia and Africa, now combined in a single daily supplement.

Common questions about Slim Coffee Booster
What is Slim Coffee Booster?
Slim Coffee Booster is a food supplement containing botanical extracts - green coffee bean, guarana, green tea, Vitamin B6 and chromium - traditionally used to support normal metabolic function and everyday energy as part of a varied diet and healthy lifestyle. It is not a medicine and is not intended to diagnose, treat, cure or prevent any disease.
What does chromium do? (chromium supplement normal blood glucose)
Chromium is a trace mineral recognised by EFSA for its contribution to normal macronutrient metabolism and to the maintenance of normal blood glucose levels. This is a nutrient-level function - it is not a claim that this product treats or prevents diabetes or any blood sugar condition.
Is this a B vitamin supplement for energy metabolism?
Yes - Slim Coffee Booster contains Vitamin B6, which contributes to normal energy-yielding metabolism and to normal protein and glycogen metabolism, as recognised by EFSA. This is a nutrient function claim for the ingredient, not a claim that the finished product treats fatigue or any medical condition.
What is yo-yo weight cycling and can nutrition tips help?
Yo-yo weight cycling refers to repeated weight loss and regain cycles, often associated with restrictive diets. Nutritional research suggests maintaining a varied, balanced diet rich in key micronutrients supports consistent metabolic health over time. No supplement replaces a sustainable lifestyle. Slim Coffee Booster is a complement to - not a substitute for - a healthy diet and regular activity.
