Discover the ingredients of DUOLIFE Fiber

Dietary fiber (dietary fiber) is a group of substances that plays an important role in the functioning of the human digestive system, although it is not digested in the digestive tract and is not absorbed into the bloodstream. There are two fractions of dietary fiber: soluble and insoluble in water1. The insoluble fiber includes compounds such as cellulose, hemicellulose and lignin. The soluble fiber fraction includes pectin, neutral hemicelluloses, gums, mucus and algal polysaccharides. Individual fractions have a specific effect on the human body.
According to the World Health Organization (WHO), the recommended daily intake of dietary fiber for adults should be 20-40 g2. The Food and Nutrition Institute provides standards for Poland at a level of 30-35 g per day for adults. As another daily intake indicator, the intake of 14 g of fiber per 1000 kcal a day is recommended3. Meanwhile, the average daily fiber consumption in Poland in 2016 was only 15.4 g per person4.
Four sources of soluble dietary fiber - DUOLIFE Fiber is a composition based on a very high content of soluble, branded dietary fiber and additional components such as ASTRAGIN ® – a proprietary formula of plant extracts of false ginseng (Panax notoginseng) and Mongolian milkvetch (Astragalus membranaceus) as well as BOSWELLIN® – a proprietary formula of frankincense (Boswellia serrata) extract.
Proprietary FIBREGUM™*** formula is a proprietary soluble acacia fiber formula derived from acacia trees grown in Africa.
Proprietary SUNFIBER®** formula is an organic, partially hydrolysed gum from Indian guar beans based on galactomannans. However, it is not identical to the widely used guar gum. Unlike conventional guar gum, it has a lower molecular weight (20-50 kDa versus 300-8000 kDa for non-hydrolysed gum) and thus a much lower viscosity (2000 times lower), which enables the preparation of an easy-to-eat formula, which is safe even when consumed large portions. In addition, unlike guar gum, it is obtained by mild enzymatic hydrolysis at low temperature (37°C) exclusively from the endosperm of seeds. The portion of SUNFIBER®** contained in 50 ml of DUOLIFE Fiber is the recommended portion to maintain the valuable effect of the ingredient.
The LOW FODMAP diet is low in short-chain, poorly absorbed, and rapidly fermentable carbohydrates with high osmotic pressure (such as lactose, fructose, and polyols). As a result, it helps to maintain optimal condition of the digestive tract and reduces bloating and intestinal discomfort, especially in people with irritable bowel syndrome or lactose intolerance.
The fiber-based formulas contained in the product: SUNFIBER®** and FIBREGUM™*** support the LOW FODMAP diet because they undergo slow fermentation, which is gentle on the intestines (Figure 1).
Figure 1: SUNFIBER®** as a beneficial fiber in the LOW FODMAP diet.
Proprietary BOSWELLIN ®* formula – has been proprietary formula of Indian frankincense extract (Boswellia serrata) standardized for 30% boswellic acid content
Proprietary ASTRAGIN® formula - is a patented, proprietary formula of false ginseng extract (Panax otoginseng) and astragalus (Astragalus membranaceus).
Complementary – a complementary product to DUOLIFE Fiber Powder, but with a completely different composition – therefore, simultaneous supplementation of both products is valuable.
Why is DUOLIFE Fiber available in two forms?

DUOLIFE Fiber is prepared in liquid form for direct consumption.
DUOLIFE Fiber Powder is prepared in powder form and can be added to a liquid or meal. Perfect for cooking. It may be a valuable element of the LOW FODMAP diet.
Better together – use DUOLIFE Fiber together with DUOLIFE Fiber Powder and provide your body with a full spectrum of ingredients. The liquid form allows you to use the full biological background in the form of fruit juices – sources of vitamins, minerals and antioxidants.  The sachets are a treasure trove of concentrated active ingredients, in high portions for optimal absorption.
