Review: Klaire Labs InterFase and InterFase Plus

TL;DR

Klaire Labs’ InterFase and InterFase Plus are engineered to dismantle harmful biofilms in the digestive tract, promoting a balanced gut microbiome. By selectively breaking down pathogenic biofilms and preserving beneficial ones, these products support overall gastrointestinal health. Additionally, they offer a unique approach by including EDTA, which disrupts biofilm formation by binding essential metals. Ideal for enhancing gut function, these supplements should be used with care, especially in individuals with specific health conditions.

Klaire Labs has developed InterFase and InterFase Plus to break down pathogenic biofilms in the digestive tract, while sparing many healthy biofilms.

Biofilms can alter the intestinal environment making it difficult or impossible for other beneficial species to get a foothold and develop healthy biofilms.

How does InterFase work?

InterFase and InterFase Plus have a multitude of enzymes demonstrated in the lab to break down bacterial biofilms from a range of bacteria and fungi, including Candida albicans and Gardnerella vaginalis.

Biofilms require calcium, iron and magnesium to develop, and InterFase Plus includes a special acid (EDTA) that binds the metals, removing them from available resources of the bacteria. Binding interrupts the biofilm creation process.

Iron-deficiency anaemia and InterFase Plus

This binding process interrupts pathogenic bacterial ability to create a biofilm, but could also cause a problem for those who are already suffering low iron.

Many pathogens use iron from our food and can be a trigger for iron-deficient anaemia. Talk to your doctor if this applies to you.

The process could be a bit hard on your body, so care needs to be taken.
