About Wynstead Hollow Nutrition
An Editorial Approach to Plant-Based Nutrition
Wynstead Hollow Nutrition was founded on a straightforward premise: that good nutritional science should be accessible, honest and clearly communicated. We draw on publicly available research - particularly the established EFSA nutrient reference framework - to formulate supplements that do what they say on the label, without inflated claims.
Our editorial team reviews each ingredient against current EU and UK nutritional guidance before a product reaches development. We do not use proprietary blends that obscure individual ingredient quantities, and we do not make therapeutic claims. Slim Coffee Booster reflects this approach: a plant extract food supplement grounded in structure/function nutrition, not medical narrative.
Every batch is manufactured in a GMP-certified facility and tested for identity, purity and potency before release. We believe informed choices are the best choices - which is why we publish our full ingredient list, NRV percentages and sourcing notes openly.

Frequently Asked Questions
Everything You Need to Know
Slim Coffee Booster is a food supplement in single-serve sachet format. It combines green coffee bean extract, green tea extract, chromium and a blend of B vitamins (B2, B6, B12). It is designed to support normal energy-yielding metabolism as part of a varied, balanced diet and healthy lifestyle. It is not a medicine.
Empty one sachet into a cup, add 200 ml of hot (not boiling) water and stir until fully dissolved. You can drink it as your morning coffee substitute or alongside your usual coffee. The recommended daily dose is one sachet per day. Do not exceed the recommended daily dose.
Chromium is an essential trace mineral. According to EFSA, chromium contributes to the maintenance of normal macronutrient metabolism and normal blood glucose levels. Slim Coffee Booster contains chromium as part of its multi-nutrient formula. This is an EFSA-authorised structure/function claim and does not imply any therapeutic effect on diabetes or any other condition.
Vitamins B2, B6 and B12 each have EFSA-authorised claims: they contribute to normal energy-yielding metabolism and to the reduction of tiredness and fatigue. Including all three allows Slim Coffee Booster to support multiple steps in normal cellular energy processes.
Yes. Slim Coffee Booster is made from plant-based extracts and does not contain animal-derived ingredients. It does not contain artificial colours. Please read the full ingredient list on packaging before use.
Green coffee bean extract naturally contains a small amount of caffeine, so Slim Coffee Booster is not entirely stimulant-free. However, it does not contain added stimulants beyond those naturally present in the plant extracts. It is not a weight loss medicine and makes no therapeutic claims regarding body weight. It is designed to support normal metabolism as part of a balanced lifestyle.
Each box contains a 30-day supply (30 individual sachets), based on the recommended dose of one sachet per day.
Store in a cool, dry place away from direct sunlight. Keep out of reach of children. Once opened, consume within the period indicated on the packaging.

Daily Routine
How to Use Slim Coffee Booster
Integrating a new supplement into your morning coffee routine should be simple. Here is a step-by-step approach.
Boil the kettle
Allow freshly boiled water to cool for 60 seconds to approximately 85-90 °C. Extremely hot water can degrade some plant compounds.
Open one sachet
Each sachet contains a pre-measured dose of Slim Coffee Booster. One sachet is the recommended daily dose - do not exceed this amount.
Dissolve and stir
Empty the sachet into a cup with 200 ml of hot water. Stir gently for 20-30 seconds until fully dissolved. The blend should yield a mild, pleasantly earthy coffee flavour.
Enjoy as your morning ritual
Drink while warm, ideally before or alongside your morning meal. Consistent daily use as part of a balanced diet helps maintain routine supplementation.
Pair with breakfast
Food supplements work best as part of a varied, balanced diet. A wholefood breakfast rich in protein and fibre complements the B vitamin and chromium content of the formula.
Stay consistent
The 30-day supply is designed to build a daily habit. Set a reminder if helpful - consistency is the most important factor in any supplementation routine.
Not suitable for children under 18. If pregnant, breastfeeding or taking medication, consult your GP or healthcare professional before use.
Lifestyle Tips
Supporting an Active Day Through Everyday Habits
Supplements are one small part of a broader picture. These evidence-informed habits complement any wellness routine focused on plant-based energy supplement support.
Prioritise a consistent morning routine
Research in behavioural science consistently links stable morning routines to higher daily energy and reduced tiredness. A defined start to the day - even 20 minutes - helps regulate circadian rhythm and supports a sense of readiness.
Move regularly throughout the day
Even light-to-moderate physical activity - a brisk 30-minute walk - is associated with normal metabolic function. The NHS recommends at least 150 minutes of moderate activity per week for healthy adults.
Eat a varied, balanced diet
Chromium, B vitamins and plant extracts work best when embedded in a diet rich in whole grains, vegetables, lean protein and healthy fats. A food supplement is a complement to good nutrition - not a substitute for it.
Stay hydrated
Adequate hydration supports normal cognitive function and energy levels. The European Food Safety Authority recommends approximately 2 litres of fluid per day for women and 2.5 litres for men, including water from food.
Support good sleep habits
Sleep quality is closely linked to energy, focus and metabolic regulation. The NHS recommends 7-9 hours per night for healthy adults. Consistent sleep and wake times are more effective than variable long-sleep catch-up sessions.
Reduce tiredness and fatigue naturally
Persistent tiredness can have many causes. Adequate micronutrient intake - particularly B vitamins, chromium and iron - supports normal energy-yielding metabolism. If fatigue is ongoing, speak with a GP to rule out underlying causes.
How It Works
The Nutrient Pathways Behind Slim Coffee Booster
A look at how the key nutrients in Slim Coffee Booster interact with normal cellular energy processes - drawn from EFSA's authorised nutrient function list.
B vitamins and energy-yielding metabolism
Vitamins B2 (riboflavin), B6 (pyridoxine) and B12 (cobalamin) each contribute to normal energy-yielding metabolism - an EFSA-authorised claim. They act as coenzymes in pathways that convert macronutrients from food into cellular energy (ATP). B vitamins also contribute to the reduction of tiredness and fatigue.
Chromium and normal macronutrient metabolism
Chromium contributes to the maintenance of normal macronutrient metabolism and normal blood glucose levels (EFSA authorised claim). It is required in only trace amounts; Slim Coffee Booster provides a daily contributing dose within the recognised safe upper intake level.
Green coffee bean extract and metabolism
Green coffee bean extract is derived from unroasted Coffea arabica beans. It contains naturally occurring chlorogenic acids and a modest amount of caffeine. Green coffee extract has been traditionally used as part of daily wellness routines and is used in food supplements formulated to support normal energy metabolism.
Green tea extract traditionally used
Camellia sinensis (green tea) has been traditionally used as part of balanced daily routines in cultures across Asia for centuries. Green tea extract contributes polyphenols to the overall plant extract profile of Slim Coffee Booster.
All nutrient function claims are drawn from the EFSA Register of authorised nutrition and health claims. These are structure/function claims and do not represent therapeutic or medicinal properties.

Verified purchase · Personal experience varies
"The B12 and B6 content was what drew me in - I was looking for a plant-based energy supplement that covered multiple B vitamins rather than just one. The fact that it works as a warm drink rather than a tablet made the daily habit stick much more easily."
