Frequently Asked Questions
Honest answers about Slim Coffee Booster, metabolism and everyday supplement use.
A note from our editorial team
When I first began researching plant-based approaches to everyday metabolism support, I was struck by how many products relied on exaggerated claims rather than transparent ingredient science. My goal with Slim Coffee Booster - and with everything at Kingsley Nutrition - was the opposite: a clean formulation built around nutrients with established EFSA-recognised contributions, served in a format people actually enjoy first thing in the morning.
We don't promise miracles. We promise a thoughtfully sourced, clearly labelled food supplement that fits naturally into your daily routine. Every EFSA claim on this page is linked to a specific nutrient at the quantity delivered per serving - not to the product as a whole. That distinction matters to us.

How to Use / Your Daily Routine
Incorporating Slim Coffee Booster into your morning takes under two minutes. Here is the recommended daily routine.
Boil your kettle
Heat fresh water to 80-90 °C - the same temperature you'd use for a quality instant coffee.
Dissolve one sachet
Tear open one sachet of Slim Coffee Booster and stir it into 200-250 ml of hot water until fully dissolved. Enjoy the natural coffee flavour.
Drink in the morning
Take your daily sachet in the morning, ideally before or with breakfast. Consistency is key - make it part of your established morning ritual.
Continue your normal day
No major dietary changes are required. Best results are reported when the supplement is used alongside a generally balanced diet and regular light activity.
Do not exceed one sachet per day. Food supplements do not replace a varied, balanced diet and a healthy lifestyle.

How It Works - The Three-Step Approach
Understanding how botanical extracts and micronutrients interact with everyday metabolism.
Step 1 - Botanical Activation
Green coffee bean and guarana extracts contribute naturally occurring phytonutrients traditionally associated with everyday energy and alertness as part of a balanced routine.
Step 2 - Micronutrient Support
Chromium at 100% NRV contributes to normal macronutrient metabolism; vitamin B6 at 100% NRV contributes to normal energy-yielding metabolism and reduction of tiredness and fatigue.
Step 3 - Consistent Routine
A daily sachet format encourages consistent use. Zinc contributes to normal carbohydrate metabolism, complementing the routine over time as part of a balanced lifestyle.

Lifestyle Tips for an Active Day
Small, consistent habits compound over time. Here are our editorial team's top suggestions to pair with your daily supplement routine.
Move a little, often
A 20-minute brisk walk each morning supports normal circulation and energy levels throughout the day - no gym required.

Seven to eight hours of quality sleep each night supports normal hormonal balance and helps maintain a healthy, active metabolism.

Plenty of vegetables, wholegrains, lean protein and healthy fats provide the micronutrient foundation that complements any supplement routine.

Starting your day with a consistent routine - including your Slim Coffee Booster sachet - creates the momentum for healthier choices throughout the day.
Connect and recharge
Social connection and stress management are increasingly recognised as important factors in supporting overall wellness and sustainable healthy habits.
