Botanical Supplement Ingredients - What's Inside & Why It Matters

An evidence-referenced guide to the key botanicals and nutrients in Slim Coffee Booster, with EFSA-authorised claims explained clearly.

Why Ingredient Transparency Matters in Botanical Supplements

When choosing a botanical supplement for metabolism support, the single most important factor is knowing exactly what you are taking and in what quantity. A full ingredient list - with precise per-serving amounts and Nutrient Reference Values (NRVs) where applicable - allows you to make an informed decision and to avoid unintentional interactions with your existing diet or medication.

The botanicals in Slim Coffee Booster originate from four continents, each with a documented history of traditional use. Below, we examine each ingredient against publicly available nutritional science and the authorised EFSA health claims that apply at qualifying doses.

Editorial note: All EFSA claims referenced on this page are authorised under EU Regulation No 432/2012 as retained in UK law. They apply at specific doses and as part of a varied and balanced diet. Food supplements are not medicines and do not treat or prevent disease.

Each Ingredient in Slim Coffee Booster - Explained

Green Coffee Bean Extract

200 mg per serving

Green coffee bean extract is derived from unroasted Coffea arabica or Coffea robusta beans. Unlike roasted coffee, it retains a higher concentration of chlorogenic acids - polyphenols that have been the subject of considerable nutritional research. The extract also contains naturally occurring caffeine at lower levels than standard coffee.

Green coffee bean is traditionally used across Asia, Africa and the Americas as part of everyday wellness routines. As a botanical ingredient in a UK food supplement, it does not carry an EFSA-authorised health claim as a standalone ingredient, but contributes to the overall botanical profile of the formula.

Key characteristic:

Natural source of chlorogenic acids; traditionally used in wellness routines across four continents.

Guaraná Seed Extract

150 mg per serving

Guaraná (Paullinia cupana) is a climbing plant native to the Amazon basin, where its seeds have been used for centuries as part of traditional dietary practices. The seed extract contains caffeine and is a widely studied botanical ingredient in food supplements marketed to support everyday energy levels naturally.

As guaraná seed extract contains caffeine, it carries an EFSA-authorised claim: caffeine contributes to normal energy-yielding metabolism. This claim is authorised for products providing at least 75 mg of caffeine per dose.

EFSA-authorised claim:

Caffeine contributes to normal energy-yielding metabolism. Note total caffeine intake from all sources.

Green Tea Leaf Extract (standardised for EGCG)

100 mg per serving · 40% EGCG

Green tea (Camellia sinensis) leaf extract, standardised to 40% epigallocatechin gallate (EGCG), is one of the most extensively researched botanical ingredients globally. It has been consumed as part of everyday dietary routines in Asia for thousands of years, and is now widely used across Europe and the Americas.

As a botanical ingredient, green tea leaf does not carry a standalone EFSA-authorised health claim for metabolism or weight management. However, standardised EGCG extracts remain a well-recognised component of botanical supplement formulations and contribute to the overall polyphenol content of Slim Coffee Booster.

Key characteristic:

Standardised botanical extract, traditionally used in Asia and Europe; contributes to total polyphenol content.

Chromium

40 µg per serving · 100% NRV

Chromium is an essential trace mineral present in many whole foods including meat, fish, whole grains and vegetables. At 40 µg per serving - meeting 100% of the Nutrient Reference Value - each dose of Slim Coffee Booster contributes a full daily amount of this mineral.

EFSA-authorised claims for chromium: Chromium contributes to normal macronutrient metabolism; chromium contributes to the maintenance of normal blood glucose levels. These claims apply in a neutral informational context and do not imply treatment of any condition.

EFSA-authorised claims (two):

1. Chromium contributes to normal macronutrient metabolism. 2. Chromium contributes to the maintenance of normal blood glucose levels.

Vitamin B6

1.4 mg per serving · 100% NRV

Vitamin B6 (pyridoxine) is a water-soluble vitamin found in foods such as poultry, fish, potatoes and bananas. It plays a well-documented role in macronutrient metabolism and is an essential component of any complete metabolic supplement formula.

EFSA-authorised claim: Vitamin B6 contributes to normal protein and glycogen metabolism. Each serving meets 100% of the NRV for this vitamin.

EFSA-authorised claim:

Vitamin B6 contributes to normal protein and glycogen metabolism.

Zinc

10 mg per serving · 100% NRV

Zinc is an essential trace element involved in numerous metabolic processes in the body. It is found naturally in meat, shellfish, legumes and seeds. A 10 mg serving provides 100% of the Nutrient Reference Value for zinc in adults.

EFSA-authorised claim: Zinc contributes to normal macronutrient metabolism. This is a well-established claim for zinc under EFSA Regulation No 432/2012.

EFSA-authorised claim:

Zinc contributes to normal macronutrient metabolism.
