BPF Gold® is the highest-flavanone concentration within the core BPF® range, standardized to 47% combined flavanones and approximately 80% total polyphenols. Derived from authentic Citrus bergamia Risso grown in Calabria, Italy, it maintains the characteristic five-flavanone profile of BPF®.
BPF Gold® is a highly concentrated Bergamot Polyphenolic Fraction (BPF®) derived from authentic Citrus bergamia Risso.
It is standardized to:
The five principal flavanones are:
The 47% designation refers specifically to the combined concentration of these characteristic flavanones—not simply to total polyphenol content.
BPF Gold® provides the highest flavanone concentration in the BPF® range for formulators seeking a premium, highly standardized citrus bergamot extract.
BPF Gold® begins with authentic Citrus bergamia Risso sourced from Calabria in Southern Italy.
Calabria is the region historically associated with commercial cultivation of bergamot and provides the botanical provenance behind the Bergamonte®/BPF® platform.
Controlled sourcing supports:
This is particularly important when comparing BPF Gold® with generic citrus or bulk bergamot extracts of uncertain botanical or geographic origin.
BPF Gold® is standardized so that its five principal bergamot flavanones collectively represent 47% of the ingredient according to specification.
Those flavanones are:
Neoeriocitrin + Naringin + Neohesperidin + Melitidin + Brutieridin
For example, 1,000 mg of an ingredient standardized to 47% combined flavanones nominally provides approximately 470 mg of combined flavanones, subject to the actual lot assay.
The high concentration allows formulators to deliver substantial quantities of the characteristic BPF® flavanones with less ingredient mass than lower-standardized BPF® grades.
BPF Gold® maintains the characteristic five-flavanone profile of authentic BPF®:
Neoeriocitrin — a citrus flavanone glycoside contributing to the overall polyphenolic profile.
Naringin — one of the principal flavanones naturally occurring in bergamot.
Neohesperidin — another important component of the characteristic citrus flavanone profile.
Melitidin — a characteristic bergamot flavanone derivative of particular interest in lipid-metabolism research.
Brutieridin — another characteristic bergamot flavanone derivative associated with the distinctive phytochemical fingerprint of Citrus bergamia.
For formulators, the complete five-flavanone profile provides considerably more information about ingredient identity than a total-polyphenol percentage alone.
Melitidin and brutieridin are characteristic bergamot flavanone derivatives and are particularly relevant to both authentication and the scientific rationale behind BPF®.
These compounds contain a structural HMG moiety that has generated scientific interest because of its relationship to pathways involved in cholesterol biosynthesis.
Their presence helps distinguish authentic bergamot polyphenolic fractions from other citrus materials that may contain common flavanones such as naringin or neohesperidin but lack the complete characteristic bergamot profile.
However, BPF Gold® should not be characterized as simply a source of melitidin and brutieridin. The scientific rationale concerns the complete polyphenolic and flavanone matrix.
They measure different things.
BPF Gold® provides approximately:
47% combined principal flavanones
and
80% total polyphenols.
Flavanones are a specific class within the broader polyphenol family. The 47% specification therefore quantifies the five principal standardized bergamot flavanones, whereas the approximately 80% value represents the broader phenolic fraction.
An ingredient described as 80% total polyphenols should not be interpreted as containing 80% bergamot flavanones.
For formulators, both measurements are useful—but they answer different analytical questions.
BPF Gold® is characterized by more than the words “bergamot extract.”
Its defining characteristics include:
A generic citrus bergamot extract may be standardized only to total polyphenols or an extraction ratio without demonstrating an equivalent flavanone profile.
Accordingly, another bergamot extract should not automatically be considered chemically or clinically equivalent to BPF Gold® simply because it carries a high total-polyphenol specification.
All are standardized members of the BPF® platform, but their flavanone concentrations differ.
Ingredient | Combined Flavanones | Approx. Total Polyphenols | General Position |
BPF® 20% | 20% | Per specification | Lower-concentration BPF® grade |
BPF® 30% | 30% | Approx. 55% | Moderate-concentration BPF® grade |
BPF® 38% | 38% | Approx. 70% | Concentrated/core BPF® grade |
BPF Gold® | 47% | Approx. 80% | Highest-concentration BPF® grade |
BPF Gold® provides the greatest flavanone density per gram.
That does not mean that 47% should automatically replace another BPF® grade in a clinically positioned formulation. The appropriate ingredient should be selected according to clinical evidence, intended application, dosage and formulation requirements.
The principal advantage is high flavanone density combined with direct clinical relevance of the 47% material.
BPF Gold® may be particularly appropriate when a formulator requires:
It also provides a useful option where the formulator wants to align the finished product specifically with research conducted using BPF 47%.
BPF Gold® is particularly relevant to formulations supporting:
Its direct human research on endothelial function and vascular responsiveness provides additional differentiation from BPF® grades primarily positioned around lipid and metabolic health.
Yes. Importantly, a published study specifically identifies the material evaluated as BPF 47%.

What It’s About
The researchers investigated whether BPF 47%, alone or in combination with other botanical extracts, could support endothelial function, reactive vasodilation and erectile function in patients with type 2 diabetes.
What They Did
Participants were treated for 120 days.
Researchers evaluated outcomes using:
BPF 47% was evaluated alone and in combination with Tribulus terrestris and Epimedium extracts.
What They Found
The researchers reported significant beneficial effects across parameters used to assess erectile function, endothelial function and penile arteriolar blood flow.
What It Means
This study is particularly important for BPF Gold® because the publication specifically identifies BPF 47% rather than merely referring generically to bergamot polyphenols.
It provides direct scientific relevance for formulations targeting vascular, endothelial and men’s health.
The endothelium is the cellular lining of the blood vessels and plays an important role in regulating vascular tone, circulation and nitric oxide signaling.
Healthy endothelial function helps blood vessels respond appropriately when increased blood flow is required.
Endothelial dysfunction is also closely associated with cardiometabolic risk factors such as:
The endothelial findings from the BPF 47% research therefore extend the scientific rationale for BPF beyond cholesterol metabolism alone.
Nitric oxide (NO) is an important signaling molecule involved in vasodilation and normal vascular responsiveness.
Oxidative stress can reduce nitric oxide bioavailability and interfere with normal endothelial function. Bergamot polyphenols provide antioxidant activity while the BPF 47% clinical research demonstrated improvements in parameters associated with vascular responsiveness.
BPF Gold® is therefore relevant to formulations supporting the vascular environment in which normal nitric oxide signaling occurs.
For formulations specifically designed around nitric oxide production and sports performance, formulators should also review N.O. Max®, which combines the BPF platform with L-citrulline.
It is more accurate to describe BPF Gold® as a bergamot polyphenol ingredient supporting endothelial and vascular function rather than as a direct nitric oxide precursor.
BPF Gold® does not supply nitric oxide in the way that L-citrulline supports endogenous arginine/NO metabolism.
Its relevance to nitric oxide comes from its relationship to:
For a dedicated nitric oxide ingredient or sports nutrition application, N.O. Max® is the more purpose-specific technology within the Bergamonte® portfolio.
Yes.
The 2016 PharmaNutrition study gives BPF 47% particular relevance to men’s vascular and sexual-health formulations.
The research evaluated erectile function together with objective measures of vascular function and blood flow.
This is important because normal erectile function is strongly dependent on:
endothelial function → nitric oxide signaling → vasodilation → blood flow.
For dietary supplement applications, claims should remain within the appropriate regulatory framework and should not suggest treatment of erectile dysfunction or diabetes.
Yes. BPF Gold® belongs to the broader BPF® platform, whose principal scientific foundation is research into healthy lipid and cholesterol metabolism.
BPF® human studies have investigated:
The high concentration of the five characteristic BPF® flavanones makes BPF Gold® particularly attractive where a formulator wants substantial flavanone delivery within a relatively small ingredient mass.
Clinical claims should nevertheless be tied to the specific research being referenced rather than assuming that every BPF® study was conducted with the 47% grade.
Yes.
BPF Gold® contains a highly concentrated fraction of bergamot polyphenols, compounds widely investigated for their antioxidant activity.
This has particular relevance to vascular health because oxidative stress can adversely affect:
The antioxidant properties of the broader BPF® matrix therefore complement its lipid and vascular-health positioning.
Dosage should be selected according to the specific application and clinical research being referenced, rather than simply calculated from the 47% concentration.
BPF Gold® provides more combined flavanones per gram than BPF® 20%, 30% or 38%, which can provide formulation advantages where ingredient space is limited.
However:
A higher standardization does not automatically justify proportionally reducing a clinically investigated dose.
For a clinically positioned finished product, formulators should review:
HP Ingredients can provide the study-specific dosage and formulation documentation applicable to BPF Gold®.
Quality evaluation should confirm both botanical identity and phytochemical composition.
Testing may include:
Chromatographic analysis such as HPLC is particularly important because it allows the characteristic individual flavanones to be identified and quantified.
The commercial lot should be supported by a lot-specific Certificate of Analysis demonstrating conformity with the established BPF Gold® specification.
Yes. Its high flavanone concentration makes BPF Gold® particularly useful where multiple active ingredients must fit within a limited serving size.
Potential formulation categories include:
Potential complementary ingredients may include L-citrulline, CoQ10, magnesium, omega-3 fatty acids and other appropriately selected cardiovascular or metabolic ingredients.
Where L-citrulline plus bergamot is the primary formulation objective, formulators should also consider N.O. Max®, the dedicated technology within the Bergamonte® portfolio.
A claim such as “80% bergamot polyphenols” is not enough to establish equivalence.
A formulator should ask:
This is particularly important with high-potency extracts because a high total-polyphenol percentage does not establish that the material contains 47% of the characteristic BPF® flavanones.
BPF Gold® 47% is available through HP Ingredients as part of the Bergamonte®/BPF® ingredient portfolio developed with Herbal & Antioxidant Derivatives (H&AD) in Calabria, Italy.
Qualified manufacturers, R&D teams and formulators may request applicable documentation including:
For manufacturers searching for a high-potency citrus bergamot extract, bulk bergamot extract, bergamot extract supplier, standardized bergamot flavonoids or clinically researched bergamot supplement ingredient, BPF Gold® provides a combination of 47% standardized flavanones, approximately 80% total polyphenols, the characteristic five-flavanone BPF® fingerprint and directly relevant human clinical research on BPF 47%.
