DuoLife Fiber Powder is a dietary supplement in the form of sachets, containing a complex of soluble dietary fiber from as many as 4 sources (in the form of branded ingredients) as well as a proprietary, branded nucleotide formula with the yeast Saccharomyces cerevisiae. The formula is composed of the highest-quality natural raw materials and is a very rich source of dietary fiber. The health-promoting effects of the ingredients contained in the dietary supplement have been documented by clinical studies.

The package contains 20 sachets.

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.

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.

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.

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.

The ingredients used in the product have been subjected to numerous, documented clinical studies.

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 system^3–6. 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).

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 weight^7-11, 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.

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 gut^13–15.

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 systems^16-17. 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.

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).

SUNFIBER^®**and INAVEA^™ BAOBAB ACACIA^*** promote the growth of good gut microbiota, supporting the action of the NUTRIOSE^®*formula on the basis of synergism.

The formula does not contain: gluten, artificial flavours and fragrances, artificial fillers and is GMO-free.

Suitable for vegans and vegetarians.

Portions in sachets to be added directly to a liquid or meal.

The product can be used, for example, to thicken soups or sauces and baked goods.
