ReFerm is a highly potent postbiotic product made from microbially fermented oats. ReFerm provides the gut with natural substances from fermentation, which strengthens the intestinal barrier and reduces lowgrade intestinal inflammation.

The condition and behavior of the intestinal flora is crucial for our health and well-being.

Many diseases originate in the intestine, and in most cases, it is due to incorrect nutrition to us as humans, but also to our intestinal microorganisms. Short-chain fatty acids and other microbial fermentation substances are necessary to build a healthy gut environment.

“In my research in microbiology, I found that microbially fermented oats can reduce inflammation in the gut and at the same time make the gut robust.”

Instead of adding new bacteria to the intestine aiming to improve the composition of intestinal flora, we supply the intestine with metabolites from a microbial fermentation of oats including short-chain fatty acids, which positively affect the metabolism in and, consequently, the behavior of the commensal intestinal flora.

Through an intestinal flora with an altered metabolism and behavior, the microorganisms may stop from irritating the body’s immune system. In other words, this converts the intestinal flora from a potential foe into a co-player for the body. As a result, inflammation is reduced, and the immune system will find its way back to its natural balanced state. The evident result is that unpleasant symptoms such as diarrhea, stomach pains, bloating and chronic fatigue are reduced or eliminated.

From this insight, I created the Life Science company Nordic Rebalance and a postbiotic product called ReFerm.

Focus areas


Postbiotics is a term for, among other things, important nutrients for the gut, which are created when certain bacteria ferment food.


Nordic Rebalance researches in postbiotics, which both reduce various degrees of inflammation and symptoms.

Clinical studies

Clinical studies conducted on patients with ulcerative colitis have been peer-reviewed and published in medical journals.


ReFerm is a highly concentrated postbiotic, which in research studies has been documented to strengthen the intestinal mucosa and reduce inflammation and symptoms.


Postbiotics are, among other things, the compounds that are produced when bacteria ferment foods. These compounds called metabolites may serve as nutrients both to the intestinal flora but also to the human cells in the intestine. When the intestinal flora is out of balance, it does not produce sufficient metabolites such as short-chain fatty acids. ReFerm’s patented manufacturing process creates a unique concentrate of microbially fermented nutrients, including short-chain fatty acids, which
