BSN Syntha-6® is a high-quality protein nutrient supporting muscle mass growth. It contains six protein fractions of different absorption kinetics. The product is enhanced with glutamine peptides, MCT oil and natural enzymes improving digestion.

The product provides proteins in an easy and controlled manner. It is especially recommended for athletes, however it can also enhance a high-protein diet. Thanks to its extensive composition, the nutrient is very universal; it will be perfect as a post-workout agent, can replace an evening meal or can be used during the day, when there are long intervals between meals.

Whey protein concentrate is created by removing water and casein from whey. It is referred to as one of the most efficient and bioavailable protein forms. It is characterised by excellent absorption and is easily digested. The protein content in a concentrate is estimated for 80%. Whey protein concentrate, like other sources of animal protein, has excellent amino acid profile. It is rich in both BCAA and glutamine, which are particularly important for the development and maintenance of muscle mass as well as for the effective post-workout regeneration. Apart from that, it contains many protein microfractions which show high bioactivity and wide spectrum of health-promoting properties.

Whey protein isolate is characterised by high biological value and purity. It contains more than 90% of protein, and due to the specific production process it is practically free from fat, cholesterol and lactose. Its amino acid profile is the same as in case of a concentrate. Thanks to that, it immediately provides amino acids and allows for using the “anabolic window” after intensive training.

Calcium caseinate is one of casein forms. The raw material for its production is denatured milk protein. Although the process changes the bioactivity of protein, it maintains the full amino acid sequence. A characteristic of this protein is an increased content of glutamine, an amino acid of high anabolic and anti-catabolic potential. Calcium caseinate is absorbed more slowly than whey protein, which results in prolonged release of amino acids. This is particularly important for the inhibition of post-workout breakdown of muscle proteins and reduction of night catabolism.

Micellar casein is obtained from milk in the process of natural microfiltration. Its peptide structure remains unchanged, which means it provides large amount of glycomacropeptides and casomorphin peptides. It retains the standard amino acid profile, is rich in glutamine and branched-chain amino acids (BCAA). It absorbs very slowly, which is why it is perfect for night use or when the intervals between meals are extremely long.

Milk proteins are obtained from cow milk. They combine casein and whey proteins. They are underestimated in supplementation and often remain in a shadow of isolates and concentrates. However, they are a model protein source with a very rich amino acid profile and high content of BCAA and lysine. The ratio of amino acid release is stable and quite slow, which is why the nutrients containing milk protein are recommended to be applied in the evening.

Ovalbumin is obtained from egg whites. It is characterised by great availability and quite slow absorption. It’s a perfect source of proteins, poor in fat and cholesterol. Apart from that, it provides many valuable vitamins and minerals.

Glutamine peptides are obtained mainly from wheat protein. They are a perfect source of glutamine and glutamic acid. Increased supply of glutamine is very beneficial for the body system. It shows strong antioxidant and immunomodulatory effects as well as protects the mucous membranes of the digestive system. It can also inhibit muscle catabolism and accelerate regeneration.

MCT oil is a saturated fatty acid, which is perfect for sports supplementation. It is easily digested and is a source of energy for muscles. In contrary to typical sources of fat, it does not increase the risk of weight gain. It may raise the intensity of thermogenesis, which promotes the reduction of unnecessary adipose tissue.

Papain and bromelain are natural enzymes that facilitate digestion of proteins and improve absorption of amino acids. Thanks to them, all protein fractions are effectively used in the body system. They also lower the risk of any digestive ailments after nutrient application.

To sum it all up, BSN Syntha-6 ® is a complex protein nutrient designed for the most demanding customers. It is especially recommended for people aiming at muscle mass building. It is an excellent choice for a last meal of the day and can be applied even when the intervals between meals are long.

Energy value


The energy value is determined by the chemical composition of the food product, by means of the so-called. physiological equivalents energy., determining the value of metabolic energy contained in 1 g of the component. Most commonly used is the equivalent of Atwater: protein 4 kcal/g for carbohydrates 4kcal/g, and for fat 9kcal/g.




Fat is an essential nutrient plant and animal organisms. Because of the nutritional value and composition of fats are divided into: saturated (mono-saturated and multi-saturated fatty acids) and unsaturated fatty acids (including essential fatty acids - EFA). The group of lipids include lipids (triacylglycerols, waxes), complex fats (glycolipids, phospholipids), sterols and isoprenoids. Saturated fatty acids is a group of fatty acids having different carbon chain lengths, in which except for the carboxyl group, each of the carbon atoms is bound by a single bond. May adversely affect the lipid profile, so they can be used in limited quantities. Fats are a concentrated source of energy, with different flavours, facilitating the consumption and swallowing of food. They have building functions (part of cell membranes and co-create the white matter of the brain). EFAs are precursors of tissue hormones and biologically active compounds. The unsaturated fatty acids include fatty acids from the group Omega-3, Omega-6 and Omega-9 (the last digit indicates, on which, counting of the end of the chain, there is a double bond in the appropriate carbon chain. The essential fatty acids include: acids, medium-Omega-3 [n-3 ] included in EFAs [essential fatty acids], and long chain (eicosapentaenoic acid [EPA] and docosahexaenoic acid [DHA]) Omega-6 and Omega-9. the number indicates that the last double bond in the carbon chain is on the third from the end carbon atom. The acids from the omega 3 group are essential components of cell membranes, they are precursors of eicosanoids and biological activators. They must be combined with ingestion in suitable proportions of Omega-6 acids.
Dosage: Depending on demand and applied diet. It is generally accepted that fats should constitute 20-30% of the energy (calorie) of meals daily.


Saturated fatty acids


Saturated fatty acids are a group of fatty acid having different carbon chain lengths, in which except for the carboxyl group, each of the carbon atoms is linked by a single bond. Saturated fatty acids are commonly known as bad fat, which might adversely affect the cholesterol level, in particular by the action of acids: lauric, myristic, palmitic, and therefore their consumption should be reduced. Research carried out in this matter do not confirm entirely the prevailing beliefs.




Carbohydrates are an essential nutrient. They are divided into: simple sugars (monosaccharides), disaccharides and polysaccharides. In terms of the human bioavailability of carbohydrates is divided into: digestabe, those which are digested in the gastrointestinal tract by transferring energy to the tissues or cells (such as starch, fructose) and indigestable, resistant to digestive enzymes (e.g. cellulose) . Affects blood glucose levels (glycemic index) and the metabolism of insulin (insulin index). The greatest demand for carbohydrates occurs before physical activity or in the middle of it, because they increase the exercise capacity, consumed after exercise provide regeneration. In the sports diet the absorption rate it is important of carbohydrates and reactions of the organism. Available in mono-preparation supplements and part of the energetic supplements, creatine stacks, nitrogen boosters.
Dosage: according to the statistics of the Institute of Food and Nutrition, carbohydrates should comprise about 50% of daily energy intake. In some diets, used
residual carbohydrate consumption, not exceeding 30g / 24h.




Sugars - is the term used to refer to the crystal structure of the carbohydrate (sugar), characterized by a sweet taste. This group includes: sucrose (obtained from sugar cane and sugar beets and natural foods), fruit sugars (fructose) and glucose. Carbohydrate intake should not exceed 10% of the energy consumed during the day meals. Excess intake of sugars leading to diseases, including diabetes, atherosclerosis and obesity. Particular caution should be performed carbohydrate intake by athletes of sculpting disciplines and people on a diet. A greater need for carbohydrates, due being easily accessible sources of energy, may be in the periods before and after workouts and before and after the fight. Preparations available at

Dietary fibre


Dietary fibre is a mixture of undigested substances and not absorbed by the human body. Due to the properties divided into: insoluble fibre (e.g. cellulose [polysaccharide] found in fruits and vegetables), partially soluble fibre (including hemicellulose occurring with cereal grains and soluble fibre (including pectin, gums, mucilages [polysaccharides]). Dietary fibre affects the digestive system and gastrointestinal system regulating its operation. By filling the stomach (satiety) reduces appetite, lowers triglycerides and cholesterol and consequently can support the weight loss process and maintain a slim body. It also affects blood glucose levels and cleansing the body of toxins. Available in powder formulations (capsules, and powders), mainly containing the soluble fraction (pectin, gums and mucilages) diet and meal replacements.
Dosage: 10-20 grams per day, before or during meals with some water.




Proteins (proteins, polypeptides) is a polymer, of which the basic units (monomers) are amino acids. Protein is composed of carbon, oxygen, nitrogen, hydrogen and sulfur, and is an elementary nutrient necessary for the proper functioning of the body, an ingredient and a component of tissues, part of the hormones and enzymes and other bioactive substances. Protein determines the proper metabolism and energy processes, as well as all other life processes. The sources of natural proteins are foods of animal origin (including meat, fish, eggs, dairy products) and plant origin (legumes, soy). Deficiency of protein leads to protein malnutrition and a significant weakening of the body. It can lead to anaemia, reduced immunity, muscle relaxation, disorders of the digestive system. Also, overdose protein is undesirable because it can lead to acidification of the body, and interfere with the digestive system and an increase in the concentration of homocysteine ​​in the blood. It is a component of many supplements and nutrients necessary for the proper functioning of the body, both showing a low physical activity, or training the strength and endurance competitions.
Dosage: strength athletes: approx. 1.7 - 2.5 g / 1 kg of body weight; endurance athletes and strength -endurance athletes approx. 1.3 - 2 g / 1 kg of body weight, people with low activity approx. 0.8 - 1.1 g / 1 kg of body weight / 24h. In estimating the amount of protein, you should take into account the intake of other nutrients (carbohydrates and fats)




Salt (sodium chloride, or table salt), natural source of electrolytes (chlorine and potassium), regulating water and electrolyte and acid-base balance of the body, affecting the nervous system and blood pressure. Sodium is an essential element for the proper growth. The proper dose of salt prevents overheating of the body and solar stroke. It provides the proper functioning of muscles and nerves the body. Chlorine in combination with sodium, is involved in the digestive process and maintains acid-base balance in the body, as antitoxin removes toxic products of metabolism in the liver. Salt is a flavour component and preservative of many foods, nutritional supplements and mixtures of electrolytes, available at

Dosage: no specific standards of consumption, used so as to provide sufficient amount of electrolytes to the body (sodium and chloride).




Sodium is an important component of the intracellular fluids, and is a regulator of acid-base balance. Along with potassium affects the proper of growth and provides the proper functioning of muscles and nerves. The source of acquisition is table salt (NaCl) and bladderwrack, shellfish, bacon, beef, and of plant beets and carrots. People on salt-free diet should avoid, among others, spicy sauces and smoked meats and sausages.
Sodium deficiency is very rare, at heaving sweating after a long effort (e.g. in the marathon).
Excess sodium increases blood pressure (especially for the elderly), edema and increased thirst. Exceeding the daily dose of 14g a day can cause poisoning.
