Why consume dietary fiber

Dietary fiber is not digested in the digestive tract and is not absorbed into the bloodstream. However, it has a very important nutritional function. It has a very positive effect on many metabolic and physiological processes in the human body and is classified as a so-called PREBIOTIC.
According to the World Health Organization (WHO), the recommended daily intake of dietary fiber for adults should be 20-40 g1. 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 recommended. Meanwhile, the average daily fiber consumption in Poland in 2016 was only 15.4 g per person2. Scientific observations show that societies consuming higher amounts of dietary fiber (up to 30-40 g a day) have lower rates of digestive, circulatory and immune problems, and related health issues.
DuoLife Fiber dietary supplement is intended for people who:

want to support the proper functioning of their digestive tract every day;
want to support the proper absorption of nutrients from the digestive tract;
have digestive problems resulting from disorders of the natural intestinal microflora or inflammatory problems;
have constipation and slow gastrointestinal passage;
want to maintain a healthy weight, thanks to the product's effect of supporting the weight loss process, reducing appetite and ensuring a prolonged feeling of fullness;
follow the so-called LOW FODMAP diet;
want to keep healthy blood glucose and cholesterol levels;
want to support optimal vascular health and regular blood pressure;
want to cleanse their body of accumulated toxins and support antioxidant processes.

High content of soluble dietary fiber
There are two groups of dietary fiber: soluble and insoluble, with slightly different physiological functions3. Soluble fiber consists mainly of pectins, gums, plant mucilages, some hemicelluloses, beta-glucans and other water-soluble compounds.
Soluble fiber:
absorbs water in the intestines and increases the weight and size of stool;
slows down the passage of food;
provides nutrients for healthy gut microbiota and stimulates the development of intestinal microflora (prebiotic effect);
increases the feeling of satiety, helps to maintain a healthy body weight, and promotes weight loss;
helps to maintain normal blood cholesterol and triglyceride levels and supports vascular function and optimal blood pressure; Properties promoting optimal cardiovascular health are mainly demonstrated by the soluble fiber fraction;
promotes delayed glucose absorption in the small intestine and reduced insulin secretion, helping to normalise blood sugar levels;
dilutes faecal matter, helping to prevent constipation;
promotes the absorption of minerals from the intestine;
has a beneficial effect on the body’s immune system.
Insoluble fiber includes mainly cellulose and lignins. Its primary function is to support the peristalsis of the digestive tract and increase the weight and size of stool.
Four sources of soluble dietary fiber
DuoLife Fiber is a 100% natural formula based on high levels of soluble, branded dietary fiber and additional ingredients, 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.
Clinical studies on ingredients
The ingredients used in the product have been subjected to numerous, documented clinical studies.
Proprietary FIBREGUM formula™***
FIBREGUM™*** is a proprietary soluble acacia fiber formula derived from acacia trees grown in Africa.
Proprietary SUNFIBER formula®**
SUNFIBER® is an organic, partially hydrolysed gum from Indian guar beans based on galactomannans. However, it is not identical to the commonly 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. SUNFIBER® has clinically and pre-clinically proven beneficial PREBIOTIC health-promoting effects and its complete fermentation process is slow and gentle on the intestines.
Proprietary BOSWELLIN formula®*
Boswellic acids from a proprietary formula of Indian frankincense (Boswellia serrata) extract – BOSWELLIN®* – help to fight inflammation in the intestines and to alleviate symptoms associated with inflammatory bowel disease4-5.
Proprietary ASTRAGIN formula®
ASTRAGIN® is a patented formula with biological action proven by 16 in-vitro and 8 in-vivo studies6-8. The results of these studies show that the synergistic formula:
promotes the absorption of peptides, amino acids, fatty acids, vitamins, and phytonutrients from the digestive tract, which is why DuoLife Fiber should best be taken with a meal, other DuoLife dietary supplements, and Shape Code®shakes;
supports the recovery of damaged intestinal epithelium;
helps to fight inflammation in the intestines;
supports the function and growth of gut microbiota;
supports the immune function of the intestinal epithelium.
LOW FODMAP approved
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, particularly SUNFIBER®** , are suitable for people on the LOW FODMAP diet, as they undergo slow fermentation process and are gentle on the intestines. The products of fiber fermentation are slowly released over time, so using SUNFIBER® helps to minimize the flatulence and bloating associated with excessively fast intestinal fermentation (Figure 1).
Figure 1: SUNFIBER®** as a beneficial fiber in the LOW FODMAP diet.
Synergy of action
The fiber contained in SUNFIBER® and FIBREGUM promotes optimal functioning of the digestive tract, supports intestinal peristalsis, regulates bowel movement, and helps to prevent flatulence, bloating and chronic constipation9. It supports the growth of good gut microboota – Bifidobacterium and Lactobacillus – and the production of short-chain fatty acids in the large intestine (the so-called postbiotics)10.
Less is more
The formula does not contain: gluten, artificial flavours and fragrances, artificial fillers and is GMO-free.
Suitable for vegans and vegetarians.
Convenient form of application
Liquid ready for immediate consumption.
Why is DuoLife Fiber available in two forms?

DuoLife Fiber supports the proper functioning of the digestive tract and supports the absorption of other nutrients from the diet. It also helps to reduce inflammation in the intestines. It is prepared in liquid form for direct consumption.
DuoLife Fiber Powder supports optimal functioning of the digestive tract, as well as the immune and nervous systems. It is based on ingredients with significant prebiotic effect. It can be added to liquids or meals. It supports the LOW FODMAP diet.
