Furoslim™ (Irvingia gabonensis Seed Extract)

A standardised African mango seed extract studied for weight and metabolic health markers

Introduction

Furoslim™ is a branded extract derived from the seeds of Irvingia gabonensis, a West African plant commonly referred to as African mango or bush mango. The seeds have a long history of traditional dietary use in West Africa, where they are valued for their thickening properties and satiating effect when consumed as part of meals.

In modern research, Irvingia gabonensis seed extracts have been investigated for their potential role in supporting body weight management and metabolic health markers in overweight individuals. Human clinical studies have explored changes in body weight, waist circumference, lipid markers, and glucose-related parameters, positioning the ingredient within a broader metabolic health context.

Botanical identity and standardisation

  • Botanical source: Irvingia gabonensis
  • Plant part used: Seed (kernel)
  • Extract type: Standardised African mango seed extract
  • Standardisation: 8% albumin

The seed kernels of Irvingia gabonensis contain a combination of soluble fibre, protein fractions, and other bioactive constituents. Furoslim™ is standardised to 8% albumin, a seed protein fraction that has been discussed in the literature in relation to satiety signalling and metabolic regulation.

Standardisation ensures a consistent composition and supports reproducibility across batches and finished formulations.

Composition and analytical characterisation

Furoslim™ is a concentrated seed extract designed for use in food supplement formulations. While the exact phytochemical profile of Irvingia gabonensis seeds is complex, analytical characterisation typically focuses on:

  • Protein fractions, including albumin
  • Soluble fibre content, contributing to viscosity and satiety
  • Low inherent sugar and fat content, relative to whole seeds

This compositional profile underpins the ingredient’s positioning in weight and metabolic health applications.

Evidence context and proposed pathways

Research into Irvingia gabonensis seed extracts has explored several physiological pathways relevant to metabolic health, including:

  • Satiety and appetite regulation, potentially influenced by soluble fibre and protein fractions
  • Adipose tissue signalling, including hormones such as leptin and adiponectin
  • Lipid and glucose metabolism, examined through changes in blood markers

These pathways are discussed in the scientific literature as part of broader investigations into dietary fibres and seed-derived bioactives, and they provide a contextual framework for interpreting human study outcomes.

Human clinical research

Body weight and waist circumference

Randomised, double-blind, placebo-controlled trials conducted in overweight adult populations have reported statistically significant reductions in body weight and waist circumference following supplementation with Irvingia gabonensis seed extract over intervention periods of approximately 8–12 weeks.

These changes were observed alongside dietary guidance and are consistent with the ingredient’s proposed role in supporting weight management strategies.

Metabolic and lipid markers

The same clinical investigations reported improvements in several metabolic markers, including:

  • Reductions in total cholesterol and triglycerides
  • Changes in fasting glucose-related parameters
  • Modulation of adipose-related hormones such as leptin and adiponectin

These findings suggest a broader metabolic context beyond body weight alone, although outcomes vary between studies.

Evidence quality considerations

Systematic reviews of randomised controlled trials have concluded that, while individual studies report positive outcomes, the overall evidence base for Irvingia gabonensis remains limited by the number of trials and variability in study design and reporting quality. As such, findings should be interpreted within the context of a developing evidence base.

Safety and tolerability

Across published human studies and reviews, Irvingia gabonensis seed extract has generally been described as well tolerated when consumed by healthy adults over short- to medium-term study periods.

Reported adverse effects have typically been mild and transient, most commonly involving gastrointestinal discomfort or headache in a small number of participants. No serious safety concerns have been identified in the available clinical literature.

Potential benefits (evidence-led)

Based on its composition and published human research, Furoslim™ may support:

  • Healthy weight management as part of a calorie-controlled diet and active lifestyle
  • Waist circumference and body composition goals in overweight individuals
  • Metabolic health markers, including lipids and glucose-related measures within normal ranges
  • Satiety and appetite control, supporting dietary adherence

These potential benefits reflect trends observed in controlled human studies and are influenced by overall dietary and lifestyle context.

Typical intake

Furoslim™ is commonly formulated at a 250 mg daily serving in food supplement products.

Summary

Furoslim™ is a standardised Irvingia gabonensis (African mango) seed extract characterised by its 8% albumin content and investigated in human clinical research focused on weight and metabolic health markers. Controlled trials have reported reductions in body weight and waist circumference, alongside improvements in selected metabolic parameters, while systematic reviews highlight the need for further high-quality research.

When used as part of a balanced diet and healthy lifestyle, Furoslim™ represents a botanically derived ingredient positioned for weight and metabolic health support with an emerging, but still developing, evidence base.

Furoslim® is available as a single-ingredient formulation here.
