Why should you 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 Powder dietary supplement is intended for people who:

want to actively support the proper functioning of their alimentary tract and digestive processes on a daily basis;
have constipation and slow gastrointestinal passage;
have gastrointestinal problems resulting from disorders of the natural intestinal microflora;
care about the optimal health of the large intestine;
follow the so-called LOW FODMAP diet;
want to maintain a healthy weight (the product supports weight loss, helps to reduce appetite and promotes a prolonged feeling of fullness);
are overweight and want to reduce their body fat;
want to keep healthy blood glucose and cholesterol levels;
want to support optimal vascular health and regular blood pressure;
want to support the functioning of their immune system;
want to cleanse the body of accumulated toxins;
want to support normal gallbladder functions;
suffer from heartburn;
want to support optimal absorption of minerals from the gut;
want to support optimal 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 Powder is a 100% natural formula based on a very high content of soluble, branded dietary fiber: 5NUTRIOSE®*, SUNFIBER®** i INAVEA BAOBAB ACACIA*** , and a proprietary Saccharomyces cerevisiae yeast formula – IMMUNEL™***, standardised to provide 60% nucleotides, supporting healthy immune and digestive system.
Clinical studies on ingredients
The ingredients used in the product have been subjected to numerous, documented clinical studies.
Proprietary NUTRIOSE formula®*
Unlike cereal fibers, the NUTRIOSE® corn fiber is non-allergenic. Its microgranulated form makes it very stable and soluble, which is why it can also be added to hot dishes, such as soups. Scientific reports show the health-promoting PREBIOTIC effects on the functioning of the digestive tract and a positive effect on the functioning of the circulatory system3–6. Clinical studies conducted for NUTRIOSE® (conference reports) have also indicated supportive effects on metabolic processes and maintenance of healthy body weight. Seventy-five percent of corn fiber undergoes slow fermentation in the large intestine (gentle on the intestines). Moreover, it is not digested by the bacteria present in the mouth and does not promote caries. The formula has a low glycemic index and is in low calories (2 kcal/g).
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® promotes optimal gastrointestinal function, healthy body weight7-11, the growth of good gut microbiota of the genus Bifidobacterium and Lactobacillus , and the production of short-chain fatty acids in the large intestine (the so-called postbiotics). As a result, it supports the functioning of the intenstines, the immune and nervous system12. The serving of SUNFIBER®** contained in 1–2 sachets of DuoLife Fiber Powder is the recommended amount to maintain the health-promoting effects of the ingredient.
Proprietary INAVEA BAOBAB ACACIA formula***
INAVEA is a synergistic, fully organic branded blend of 2 sources of soluble dietary fiber from African plants: Seyal acacia and baobab. A serving of 5 g/day of INAVEA (contained in 2 sachets of DuoLife Fiber Powder) shows a documented PREBIOTIC effect, promoting the growth of good gut microbiota, in particular Bifidobacterium. Additionally, INAVEA™ supports metabolic functions and helps the body to fight inflammation in the gut13–15.
Proprietary IMMUNEL formula™***
Nucleotides contained in IMMUNEL™*** are a source of important signalling and precursor molecules in the body, and can be reused to build new nucleic acid molecules contained in cell nuclei. They are a very important, though still underestimated, component of a low-processed diet, necessary for proper functioning of the immune and digestive systems16-17. Nucleotides from the yeast Saccharomyces cerevisiae can promote the regeneration of damaged cells and tissues of the digestive tract, supporting the body's non-specific immunity and the so-called intestinal barrier. The recommended daily serving of IMMUNEL™*** ( 300 mg) is contained in 2 sachets of DuoLife Fiber Powder.
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: SUNFIBER®**, NUTRIOSE®* and INAVEA BAOBAB ACACIA*** are suitable for people on the LOW FODMAP diet, as they undergo a slow fermentation process and are gentle on the intenstines. The products of fiber fermentation are slowly released over time, so using SUNFIBER®** along with NUTRIOSE®* and INAVEA BAOBAB ACACIA*** helps to minimize the flatulence and bloating associated with excessively fast intestinal fermentation (Figure 1).

Synergy of action
SUNFIBER®**and INAVEA BAOBAB ACACIA*** promote the growth of good gut microbiota, supporting the action of the NUTRIOSE®*formula on the basis of synergism.
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
Portions in sachets to be added directly to a liquid or meal.
Perfect for cooking
The product can be used, for example, to thicken soups or sauces and baked goods.
