What's Inside
Green coffee extract food supplement - full ingredient profile
Last updated: 2 August 2026 · By Clara Maitland, Nutrition Writer
A transparent, nutrient-by-nutrient breakdown of Slim Coffee Booster: what each ingredient is, what the EFSA-authorised claims mean, and how they fit a balanced daily routine.
Ingredient Overview
Plant extracts traditionally used for wellness - meets modern nutrition science
Slim Coffee Booster draws on botanical ingredients sourced from multiple regions, each selected for a well-documented nutritional role. Below is every active ingredient, its source, and the corresponding EFSA-authorised claim where applicable.
Green coffee bean extract
Sourced from unroasted Coffea arabica beans. Naturally rich in chlorogenic acids. Contributes to normal energy-yielding metabolism as part of a balanced diet.
Chromium
An essential trace mineral. EFSA-authorised claim: chromium contributes to normal macronutrient metabolism and the maintenance of normal blood glucose levels.
Vitamin B6
A water-soluble B vitamin. EFSA-authorised claim: vitamin B6 contributes to normal protein and glycogen metabolism - relevant for active adults.
Zinc
An essential mineral found widely in plant-based foods. EFSA-authorised claim: zinc contributes to normal macronutrient metabolism and to the protection of cells from oxidative stress.

In Context
Ingredients & nutritional science - key figures
Deep Dive
What each ingredient actually does
The claims below are EFSA-authorised structure/function claims tied to named nutrients at specified levels. They do not imply that Slim Coffee Booster diagnoses, treats or prevents any condition.
Green coffee bean extract - the botanical backbone
Green coffee beans are simply unroasted Coffea arabica beans - the same plant that produces your morning espresso, harvested before the roasting process that browns and transforms them. The lack of roasting preserves higher concentrations of chlorogenic acids, a family of polyphenols that have attracted growing interest in nutritional science.
Green coffee bean extract contributes to normal energy-yielding metabolism as part of a balanced diet and active lifestyle. It has been used in traditional wellness practices globally and is now a common ingredient in contemporary botanical supplement formulations.
EFSA note: General function claims for plant extracts are under ongoing review by EFSA. The energy metabolism claim for green coffee is made in a food supplement context as part of a balanced diet. This is not a medicinal claim.
Chromium - normal macronutrient metabolism & blood glucose maintenance
Chromium is an essential trace element found naturally in whole grains, broccoli, green beans and other foods. At the nutrient reference value level (40 µg per day), chromium has two EFSA-authorised health claims: it contributes to normal macronutrient metabolism, and to the maintenance of normal blood glucose levels.
This means adequate chromium intake is associated with the normal processing of carbohydrates, fats and proteins by the body, and with the body's ability to maintain blood glucose within the normal range as part of healthy metabolic function. These are nutrient-level claims - they do not mean chromium treats diabetes or any blood glucose disorder.

Vitamin B6 - protein & glycogen metabolism
Vitamin B6 (pyridoxine) is a water-soluble vitamin that the body uses as a cofactor in over 100 enzymatic reactions, many of which involve amino acid and protein processing. The EFSA-authorised claim states that vitamin B6 contributes to normal protein and glycogen metabolism - the processes by which the body stores and releases energy from carbohydrate and protein sources.
For adults who are physically active, adequate B6 intake is particularly relevant given the role glycogen plays in fuelling muscular activity. One daily serving of Slim Coffee Booster provides 100% of the NRV for vitamin B6.

Zinc - macronutrient metabolism & cellular protection
Zinc is an essential mineral involved in over 300 enzymatic processes in the human body. Among the EFSA-authorised claims for zinc: it contributes to normal macronutrient metabolism and to the protection of cells from oxidative stress. Zinc also contributes to normal DNA synthesis and to the maintenance of normal immune function.
Zinc is found in seeds, legumes, wholegrains and nuts. Many adults in the UK may not consistently achieve the NRV through diet alone, making supplementation a practical option alongside a varied diet.
