GCB70® Green Coffee Bean Extract
A clinically evaluated green coffee bean extract standardised to 70% chlorogenic acids, with low caffeine content and analytical characterisation for consistency, identity and purity.
Introduction
GCB70® is a standardised green coffee bean extract derived from Coffea species and enriched to contain high levels of chlorogenic acids, a group of naturally occurring polyphenols found in unroasted coffee beans.
Unlike roasted coffee, where chlorogenic acids are significantly reduced, green coffee bean extracts provide a concentrated source of these bioactive compounds.
Green coffee bean extracts have been studied in relation to body weight management, metabolic balance and glycaemic markers. GCB70® has been evaluated in human clinical research exploring changes in body weight, body composition, waist circumference and metabolic parameters in overweight individuals.

Botanical Identity & Standardisation
Green coffee beans are naturally rich in chlorogenic acids, a family of polyphenolic compounds that include several caffeoylquinic acid isomers.
GCB70® is standardised to ensure a consistent chlorogenic acid content, allowing alignment with material evaluated in human studies.
Key Extract Features
- Derived from unroasted Coffea robusta beans
- Standardised to ≥70% chlorogenic acids
- Low caffeine content, ≤2.0%
- Analysed using HPLC methods
- Clinically evaluated in overweight adults
Chlorogenic Acids
Chlorogenic acids are naturally occurring polyphenols found in green coffee beans and are the primary compounds used to characterise and standardise GCB70®.
Why Standardisation Matters
Standardisation to a defined chlorogenic acid profile supports a more consistent and transparent approach compared with loosely characterised botanical extracts.
- Defined chlorogenic acid content
- Low caffeine specification
- Consistent active compound profile
- Alignment with clinically evaluated material
Composition & Analytical Quality
GCB70® is characterised using analytical techniques commonly applied to botanical extracts intended for food supplement use.
| Parameter | Specification / Typical Result |
|---|---|
| Total Chlorogenic Acids | ≥70.0% specification; typical result ~72.2% |
| 5-O-caffeoylquinic Acid | ≥25.0% specification; typical result ~28.8% |
| Caffeine | ≤2.0% specification; typical result ~0.76% |
| Appearance | Pale yellow to brown coloured powder |
| Odour & Taste | Characteristic |
| Particle Size | Suitable for powder formulations |
| Bulk Density | Controlled to support uniform handling and dosing |
Analytical Characterisation & Ingredient Verification
GCB70® is assessed against defined identity, purity and quality criteria to confirm suitability for use in high-quality supplement formulations.
Identity Confirmation
Botanical identity is verified using thin-layer chromatography (TLC), with results confirming the presence of chlorogenic acids characteristic of green coffee bean extracts.
Consistency & Repeatability
Chromatographic analysis produces a characteristic chemical fingerprint for the extract. Across repeated analyses, key chlorogenic acid components appear at consistent positions and relative intensities, demonstrating a repeatable and stable composition from batch to batch.
Purity & Quality Controls
In addition to active compound verification, the ingredient is assessed against established quality parameters.
- Moisture content controlled to support stability
- Residual solvents monitored and maintained below specified limits
- Microbiological quality assessed against food supplement criteria
- Absence of specified pathogenic organisms
- Heavy metals including lead, arsenic, mercury and cadmium tested against defined limits
Together, these measures confirm that GCB70® meets its defined specification and maintains a consistent analytical profile suitable for food supplement use.
Human Clinical Research
Body Weight & Metabolic Outcomes
A controlled human clinical evaluation investigated the effects of GCB70® supplementation in overweight adults over a 12-week period. Participants consumed a total daily intake of 1,000mg of the extract.
Reported outcomes included changes in body weight, body mass index, waist circumference and selected metabolic markers.
Reported Study Outcomes
- Reductions in body weight and body mass index (BMI)
- Decreases in waist circumference
- Improvements in fasting blood glucose and HbA1c values
- Reductions in plasma leptin levels
- Standard blood chemistry parameters remained within normal ranges
Safety Observations
No serious adverse effects were reported during the intervention period, supporting a favourable tolerability profile for GCB70® when used at the studied intake level.
Evidence-Led Use Context
Based on its composition and available human research, GCB70® is commonly discussed in relation to body composition, metabolic health and glycaemic marker research.
These outcomes reflect findings from controlled human research and are dependent on overall dietary and lifestyle context.
Typical Intake Used in Studies
Human clinical evaluation of GCB70® has used a daily intake of 1,000mg, consumed consistently over a 12-week period.
Formulation Context
GCB70® is suitable for supplement formulations focused on standardised green coffee bean extract, chlorogenic acid content and low-caffeine botanical extract delivery.
Summary
GCB70® is a well-characterised, standardised green coffee bean extract enriched to ≥70% chlorogenic acids. Analytical verification confirms a consistent chlorogenic acid profile, low caffeine content and compliance with purity and quality criteria.
Human clinical research has reported changes in body weight, BMI, waist circumference and selected metabolic markers, alongside a favourable safety profile.
For those seeking a green coffee bean extract supported by analytical characterisation and human clinical evaluation, GCB70® represents a transparent and evidence-led option.
