FENACTIVE® is a standardized complex of plant extracts, rich in polyphenols, designed to support and restore the body’s immunity, in particular against upper respiratory tract infections (URTI) of viral and bacterial origin. Aronia melanocarpa (Michaux) + Sambucus nigra L. have different but complementary anthocyanin fractions in their composition, which is widely proven and brings significant health benefits. As a result of our own laboratory work on the formulation, we have obtained an innovative specific complex with an extended, synergic spectrum of biologically active ingredients.


The FENACTIVE® Aronia melanocarpa + Sambucus nigra L. complex has been standardised simultaneously regarding the content of:

  • anthocyanins (HPLC)
  • polyphenols (UV)

It is patented in-house production from selected raw materials. Thanks to contracted, local sources of raw ingredients we guarantee full control over the origins and quality of the extracts. Reference FENACTIVE® complex contains 10% anthocyanins / 15% polyphenols

Recommended use and dosage

FENACTIVE® comes in the form of black fine powder, with good technological properties. It is convenient to produce formulations, suitable for capsules, tablets, liquid forms. Suggested dosage: 200-250 mg, once a day.

Target group

The FENACTIVE® complex is recommended for use by the general population. It is particularly beneficial for the population of children (frequent respiratory infections) and seniors (natural aging of the immune system induces chronic inflammatory processes underlying a number of serious diseases). Numerous in vitro and in vivo studies indicate the beneficial effects of Aronia melanocarpa and Sambucus nigra L.

FENACTIVE® trademark and formulation

The FENACTIVE® registered trademark belongs to GREENVIT. Its use is exclusively related to the purchased complex of extracts. The use of the FENACTIVE® trademark in finished products containing this complex mixed with other ingredients belonging to the same botanical family is not permitted.

What makes FENACTIVE® unique?

First original composition on market with own research
Patent pending combination of two own standardised extracts
Antiviral activity against respiratory viruses influenza and coronavirus
The inventive synergy developed by greenvit has been proven to be more effective than the two single extracts separately

Fusion of the health benefits of two traditionally used fruits with the highest ORAC scale indices – aronia and elderberry – the innovative, standardised composition of FENACTIVE® supports the body’s natural defensive functions.

Antiviral properties

Studies to determine antiviral properties of the FENACTIVE® complex were conducted in the reference Laboratory of Virology, Hirszfeld Institute of Immunology and Experimental Therapy, Polish Academy of Sciences, Wroclaw, Poland. After conducting experiments according to the study protocol, it was found that FENACTIVE® showed significant antiviral activity when administered after infection with the test viruses.

Immunostimulating effect

In order to confirm immunostimulating effect of the FENACTIVE® composition and to compare the effect of single elderberry and chokeberry extracts, tests were performed on PBMC (peripheral blood mononuclear cells). It has been confirmed that immunostimulating effect of the appropriately selected composition of Fenactive™ is stronger (more beneficial) than that of the individual elderberry and chokeberry extracts.

Antibacterial effect

FENACTIVE® was tested for their antibacterial activity against pathogenic bacteria: Staphylococcus aureus and Escherichia coli. In the tests, antibacterial effect of the extracts was observed in different concentrations.
