Enzyme combination with EDTA for enhanced disruption of biofilm matrix†
Benefits and Features
- EDTA binds the metals needed for biofilm formation for anti-biofilm activity†
- Helps degrade bacterial and yeast cell wall structures†
- Encourages healthy intestinal microbial communities†
Biofilms are protective encasements formed by microorganisms making them highly resistant to antimicrobials. Ther-Biotic® InterFase® Plus is a unique enzyme formulation designed to break up the biofilm matrix that embeds the GI organisms along with EDTA to bind biofilm-forming metals.†
Detail Overview
Ther-Biotic® InterFase® Plus combines the same unique enzyme formulation found in Ther-Biotic® InterFase® with ethylenediaminetetraacetic acid (EDTA). The presence of calcium, iron, and magnesium is essential for biofilm creation and serves to cross-link the anionic regions of polymers. Ther-Biotic® InterFase® Plus includes EDTA which binds the metals needed for biofilm formation. Ther-Biotic® InterFase® Plus can be used for maximum antibiofilm activity.†
The capsules should be taken away from meals to maximize the enzyme effects.
