Fava bean protein isolate

is a highly concentrated plant-based protein ingredient and one of the key components of DUOLIFE Slim Shake. Obtained from fava bean seeds, it is characterised by a high protein concentration and beneficial functional properties.

Fava bean protein is distinguished by its characteristic amino acid profile, which includes all essential amino acids. It contains, among others, leucine, isoleucine, valine, lysine, threonine, and phenylalanine.

Fava bean protein isolate is characterised by a high protein content – published data for this isolate report a protein content of approximately 84%.

Protein:

  • contributes to the growth of muscle mass;
  • helps to maintain muscle mass;
  • helps to maintain healthy bones.

 

 

Pea protein concentrate

is a plant-based ingredient obtained from pea seeds, which undergo processes that allow the protein contained in them to be concentrated. It is characterised by a high content of plant-based protein and is a valued ingredient in modern food formulations and dietary supplements. It is a valuable alternative to animal-derived proteins and meets the needs of people choosing products based on plant-based ingredients. In the DUOLIFE Slim Shake formulation, it forms a comprehensive protein base together with fava bean protein isolate.

Protein:

  • contributes to the growth of muscle mass;
  • helps to maintain muscle mass;
  • helps to maintain healthy bones.

 

 

FIBRULINE™

inulin from the common chicory root. FIBRULINE™ is a branded, clinically studied ingredient. Inulin belongs to the soluble fibre fraction. It is not digested by the human body, but is fermented in the large intestine through the action of the bacterial flora. This process produces short-chain organic acids (acetic, propionic, lactic and butyric acids), which support intestinal peristalsis. Inulin is classified as a prebiotic and is therefore one of the so-called functional food ingredients that support the human body.

Chicory:

  • supports weight management and weight control as part of a balanced diet;
  • supports digestion, the production of digestive juices and intestinal peristalsis;
  • supports liver function;
  • supports the maintenance of the heart and blood vessels in optimal condition. It also helps to maintain optimal blood sugar levels. 

 

 

Defatted ground flaxseed

is an ingredient obtained from flax seeds (Linum usitatissimum L.), from which some of the oil has been removed and the remaining material has been ground. This makes it a concentrated source of naturally occurring flax components, including protein, dietary fibre, and lignans. In DUOLIFE Slim Shake, flax seeds are used in defatted form. The defatting process involves removing a significant proportion of the oil naturally present in the seeds. As a result, the relative proportion of non-fat components, particularly fibre and protein, in the remaining raw material increases. The defatted raw material is also easier to use in the formulation of a shake with a controlled fat content and energy value.

Flax seeds:

  • contribute to maintaining body weight;
  • help reduce calorie intake;
  • support feelings of fullness and satiety; 
  • support intestinal peristalsis.

 

 

Sanacel®

oat fibre – a natural fibre concentrate obtained from fibre-rich parts of the oat plant and oat husks. Due to its high fibre content, it is a valuable ingredient in formulations where increasing the proportion of dietary fibre is important.

 

 

Medium-chain triglycerides (MCTs) 

are fats that undergo a different process of digestion and absorption from typical fats. They are absorbed directly by the intestinal epithelial cells and are then transported straight to the liver without undergoing incorporation into chylomicrons. MCTs can be digested without the presence of lipase and emulsifying salts of bile acids. Therefore, they digest faster and easier than their long-chain counterparts.

 

 

Arrowroot flour

arrowroot is a tropical plant whose underground rhizomes are naturally rich in starch. Its characteristic component is starch with a high amylose content – a fraction of the polysaccharide. In addition to starch, arrowroot also contains naturally occurring plant compounds, including polyphenols, flavonoids, tannins, and sterols.

 

 

Bitter melon fruit extract

Bitter melon, also known as karela, is a distinctive plant from the cucumber family, particularly popular in Asian cuisine. Its fruits are distinguished by an intensely bitter taste, which is associated, among other things, with the presence of specific plant compounds.

From a phytochemical perspective, Momordica charantia is particularly interesting due to its cucurbitane-type triterpenoids, including momordicins and momordicosides, as well as saponins, flavonoids, phenolic compounds, sterols, and polypeptides. One of the best-known compounds characteristic of bitter melon is charantin, described in the literature as a mixture of steroidal glycosides.

The fruits also contain naturally occurring polyphenolic compounds, including gallic acid, chlorogenic acid, catechins and naringenin, as well as carotenoids such as β-carotene and lutein.

 

 

Green tea leaf extract

standardised to 98% polyphenols (including 2% caffeine). Green tea is one of the best-studied plant-based raw materials in terms of its polyphenol composition. Unlike black tea, its leaves are not fully fermented, allowing them to retain their characteristic catechin profile. The most important group of polyphenols in green tea is catechins, among which EGCG (epigallocatechin gallate) is particularly prominent, along with EGC, ECG and EC – epigallocatechin, epicatechin gallate, and epicatechin. EGCG is the most abundant catechin found in green tea.

The product contains green tea leaf extract standardised to 98% polyphenols, which means a very high concentration of this group of naturally occurring plant compounds. At the same time, it contains 2% caffeine, meaning that the extract’s profile includes both polyphenols characteristic of green tea and a naturally occurring alkaloid.

In addition to catechins, the leaves of Camellia sinensis also contain L-theanine, gallic acid, and other phenolic compounds and aromatic constituents. The exact profile depends on the tea variety, growing conditions, harvesting, and processing methods.

 

 

White mulberry leaf extract

mulberry leaves are a source of many valuable substances; they contain protein, dietary fibre, vitamins (vitamin C, beta-carotene), micro- and macronutrients (Fe, Zn, Ca, P, Mg), polyphenols (mainly flavonoids and anthocyanins) and alkaloids, the most important of which is 1-deoxynojirimycin (DNJ).

White mulberry may help maintain the balance of carbohydrate metabolism in the body.

 

 

Cinnamon bark extract

cinnamon is a popular culinary spice, but it also has many valuable properties.

Cinnamon:

  • helps maintain normal blood glucose levels; 
  • supports digestion; 
  • supports cardiovascular system function; helps to maintain normal blood lipid levels. Supports the production of HDL (good) cholesterol.

 

 

Formula containing vitamins and iron

it contains: vitamin B1 (thiamine mononitrate), vitamin B2 (riboflavin), vitamin B6 (pyridoxal 5′-phosphate), vitamin B12 (methylcobalamin), vitamin D (cholecalciferol), folic acid (pteroylmonoglutamic acid), biotin (D-biotin), niacin (nicotinamide), iron (ferrous lactate).

B vitamins support, among other things, normal energy-yielding metabolism and nervous system function, normal psychological function, the reduction of tiredness and fatigue, and the normal function of the immune system. Selected vitamins also help to maintain healthy skin and mucous membranes.

Vitamin D helps with the normal function of the immune system and muscles, the maintenance of healthy bones and teeth, the normal absorption and utilisation of calcium and phosphorus, and the maintenance of normal blood calcium levels.

Iron helps with normal formation of red blood cells and haemoglobin, normal oxygen transport, the maintenance of normal cognitive function, normal function of the immune system, the reduction of tiredness and fatigue, and normal energy-yielding metabolism.

 

 

Bestevia®

is a modern sweetener based on steviol glycosides – naturally occurring compounds found in the leaves of stevia (Stevia rebaudiana). It is precisely the steviol glycosides that are responsible for stevia’s characteristic, intensely sweet taste. Unlike conventional stevia extract, the production of enzymatically obtained steviol glycosides uses enzymatic bioconversion, which allows the structure of individual glycosides to be modified. Depending on the technology used, this may result in the formation of, among others, rebaudioside M (Reb M), rebaudioside D (Reb D), or rebaudioside AM (Reb AM). These compounds belong to the same family of steviol glycosides, but differ in molecular structure, sweetness intensity, and sensory profile. Bestevia® makes it possible to use modern enzymatic technology to obtain a high-quality sweetening profile that works well in formulations where intense sweetness is desired while using a small amount of sweetener.
