GSE is the acronym with which Grapefruit Seed Extract is identified in the USA.

The GSE® brand, whose formulation is the basis of most of our products, is exclusively owned by Prodeco Pharma in Italy. The extract is known for its excellent properties that are selective, antifungal, antiviral, parasiticidal, cytoprotective, repairer and broad-spectrum antimicrobial.

A powerful antimicrobial

Extensive testing carried out at laboratories and universities around the world has proven GSE to be effective against bacteria, viruses, fungi, yeast and parasites. What’s most surprising and unrivalled in the field is, beyond its efficacy, its speed of action.

A study showed that grapefruit seed extract when compared with other antimicrobial substances is 10 to 100 times more effective against the microorganisms under examination.

Selective and safe

GSE represents a valid alternative treatment against many bacterial infections that do not require the use of antibiotics. This is not only due to its efficacy, now widely recognised, but also because of one feature that gives GSE the edge over antibiotics: its selectivity. Selectivity means it is able to distinguish between pathogenic bacteria, considered enemies, and beneficial bacteria that make up the physiological bacterial flora.

Safety is another important GSE feature: the harmlessness of GSE has been largely demonstrated as its L.D. is greater than 5000 mg./kg of body weight. This means that an adult should swallow 4.000 times the recommended dose every day for two weeks in order to have a 50% risk of intoxication. In addition to this, grapefruit seed extract does not interact with other medications and does not significantly harm beneficial intestinal flora. GSE can be defined a “global” remedy as its properties allow endless applications and also because it has undergone testing in laboratories, clinics and universities all over the world, all of which have validated its effectiveness.


A gift from nature that keeps its promises

Endless application possibilities

Endless application possibilities are offered by GSE thanks to its properties – effective antibacterial, antiviral, parasiticidal, antifungal, cytoprotective and mucosa repairer – and its flexibility of use (both dry and liquid extracts are conveyable through water and oil).

We believe that the best way to exploit such a powerful and broad-spectrum effective remedy is to combine it with other natural elements with specificity of action, rather than using it alone. The result is the creation of real “complete products” with GSE as the main component in the proper dosage, aimed at solving specific health problems. With this approach, different product lines have been created to provide effective treatment for a broad range of ailments. Listed below are the health issues that can currently be treated using GSE-based supplements:


  • CANDIDIASIS (systemic, vaginal, oral, etc.)
  • INTESTINAL DISORDERS (constipation, diarrhoea, colitis, abdominal pain, etc.)
  • DIARRHEA (viral, bacterial, etc.)
  • GASTRIC DISORDERS (digestive disorders, infections by Helicobacter Pylori, etc.)
  • RESPIRATORY SYSTEM AFFECTIONS (cold, sinusitis, tracheitis, bronchitis, etc.)
  • CONJUNCTIVITIS (bacterial, viral, allergic, by chemical or physical agents, blepharitis, sty, etc.)
  • ACNE (spots, blackheads)
  • DERMATITIS (eczema, erythema, athlete’s foot, wounds, burns, etc.)
  • MYCOSIS (skin, nails, warts, etc.)
  • PEDICULOSIS (prevention and treatment)

At present, millions of people all over the world benefit from the extraordinary properties of Grapefruit Seed Extract. However, in some respects, it is still a remedy for the “élite”. It would really be most remarkable if all of humanity could profit from this precious natural gift: we hope that globalization – a term often associated with negative connotations – may help this dream come true.
