You have got questions about the product

  • Advanced supplement that comprehensively supports the functioning of the joints
  • Contains two high-quality fish collagen complexes
  • Provides a complex of extracts with anti-inflammatory properties
  • Chondroitin and glucosamine of natural origin
  • GMO-free

Aliness Duoflexin is an advanced supplement designed to help to prevent joint problems. It provides many substances recommended to promote the condition of ligaments and cartilage.

The core of the product are two collagen complexes based on Abyss fish collagen. Collagen is a protein that gives tissues flexibility and tolerance to stretching. Its proper synthesis is necessary to maintain the normal functions of the musculoskeletal system, so it is no wonder that it is in the center of attention of people struggling with joint problems. The first complex, Cartidyss ™, provides type II collagen. It is a type of collagen that is characteristic of articular cartilage. The second, Collyss™, is a source of type I collagen, characteristic of ligaments and bones. Both are distinguished by high quality. They are obtained from the valued fish raw material, in contrast to the popular, cheaper poultry collagen often present in dietary supplements.

The Cartidyss™ collagen complex also includes chondroitin sulfate and glucosamine sulfate. These compounds are found in human articular cartilage. There are sources pointing to the ability of these substances to promote joint health, especially when taken together. The Cartidyss™ complex is also a source of hyaluronic acid, which lubricates the synovial fluid in the human body thanks to its ability to bind water. Hyaluronic acid can also be found in the Nutrelix™ snail mucus extract, which is also a natural source of allantoin and glycosaminoglycans.

The composition also contains several extracts recommended as an adjuvant in joint pain due to their anti-inflammatory effect. Indian oli-banum extract (Boswellia serrata), BosFlex, standardized to 70% of boswellic acids, ginger extract, GingerPro, standardized to 5% of gingerols, as well as FlexiGo™ devil's claw extract with DER 4:1, thanks to which each capsule of this product provides the essence of pro-health properties of the substances. The composition also includes acerola extract, which provides vitamin C that is involved in the metabolism of collagen in the human body.

To sum up, ALINESS Duoflexin is a supplement that comprehensively supports joint functions. It will be perfect for all people who care about the prophylaxis of musculoskeletal health, as well as for those who are looking for support in the treatment of joint ailments.

Collagen is a major component that builds connective tissue (tendons, ligaments cartilage, bone, and blood vessels) from the group of fibrous proteins (i.e. scleroprotein), representing a quarter of the content of protein in the body. It is composed of amino acids (glycine, hydroxylysine, hydroxyproline and proline). Distinguished are eight types of collagen located in different parts of the human body. The source of the acquisition is gelatin (a component of the connective tissue of animal origin). It occurs most frequently in the form of processed collagen hydrolyzate characterized by a high and a good absorbency of amino acids. Recommended in sports supplementation and physically active people, as well as during convalescence after injuries and certain diseases. Available as mono-preparation supplement or of multi-compound supplement (usually also containing chondroitin, hyaluronic acid, and ascorbic acid).
Dosage: 10-20 g per day.


Chondroitin sulfate


Chondroitin sulfate has chondroitin in its composition, belonging to the glycosaminoglycans, affecting the maintenance of joint stability and strength (building component of cartilage). Chondroitin sulfate proteins involved with the synthesis of proteoglycans. It is synthesized in the body or delivered in the foods of animal origin (e.g. containing tissue). It is used by athletes in the disciplines greatly aggravating the locomotor system with exercises, as well as in the treatment of sports injuries and joint recovery and rehabilitation after injuries, increased demand also occurs in people of advanced age. In the sports supplementation is a component of multi-component combined supplements, often containing hyaluronic acid, glucosamine and hydrolysed collagen, supporting the functioning of the locomotor system.
Dosage: 500-1500 mg per day.


Hyaluronic acid


Hyaluronic acid (sodium hyaluronate) is a glycosaminoglycan, which do not form covalent bonds with proteins and does not contain sulfate groups. Creates so called proteoglycans aggregates absorbing water and which are responsible for the resistance of cartilage. It is one of the components responsible for the intra-articular fluid viscosity. It takes part in the regeneration of skin tissue. It is synthesized in the body providing a full daily demand. Supplementation applies to athletes exposed to overload of the locomotor system. It is a component of preparations supporting the regeneration of joints and tendons and cosmetics supporting the condition of hair, skin and nails.


Boswellia serrata


Boswellia serrata extract, shows efficacy in the treatment of degenerative arthritis (particularly the knee), rheumatoid arthritis, colitis and Crohn's disease.

Devil’s claw acts also as an antioxidant. It has the ability to reduce the amount of free radicals in the body and thus promotes health of the entire body. Adequate antioxidant intake is indicated as one of the factors delaying ageing processes.

In addition, devil’s claw may increase insulin sensitivity and therefore promote carbohydrate metabolism.

Ginger root


Ginger root (Zingiber Officinale Radix) as a herbal raw material is widely used as a source of, among others, gingerols. Compounds containing organic components of ginger root are characterized by high biological activity. Ginger root is used in medicine, due to the prevention of infection, to ensure a balance of gastrointestinal bacteria, involved in the production of bile. It has a beneficial effect on the functioning of the circulatory system as an antioxidant, lowers blood pressure, causing a delay in the processes of formation of LDL cholesterol (inhibitor). As a thermogenic it reduces appetite processes and sometimes it is a component of weight loss complexes. Through participation in the transformation of thermogenic lipolysis, is one of the valuable fat burners. The active substances contained in it are a component of arthritis regenerators (in combination with glucosamine including or curcumin). In the sports supplementation it is valued for its anti-inflammatory properties to support the process of healing and recovery after an injury of motor organs (especially the joints). It co-creates so called joints regenerators with chondroitin, glucosamine and curcumin.



Gingerols - contained in the ginger rhizome active ingredients are derivatives of phenylpropane. Anti-inflammatory, diaphoretic, warming and regulating the digestive system and digestive tract. They are an antioxidant that reduces oxidation of LDL cholesterol and the building-up of atherosclerotic plaques, lower blood pressure. They also are used in the supplements for the reduction of body fat. When combined with glucosamine, chondroitin and curcumin allow for the regeneration of joints. In the In the sports supplementation they are used for their anti-inflammatory potential, facilitating treatment and rehabilitation after injuries of motoric organs.
Dosage: 10-20 mg per day.




Acerola (Barbados cherry) is a rich source of ascorbic acid (vitamin C), also contains B vitamins, vitamin A, bioflavonoids and carotenoids. Vitamin C contained in the acerola stimulates the production of collagen, which is important for the proper functioning of the locomotor system, accelerating their regeneration during convalescence after injuries and contusions. . It strengthens the immune and cardiovascular system (improving the condition of blood vessels), is a potent antioxidant. It shows a slight diuretic effect, and relieves disorders of gastrointestinal and digestive tract. It is essential in the synthesis of hormones and transmitters, neutralizes free radicals and increases the absorption of non-haem iron. It is in a composition of the complexes multivitamin supplements, supporting immune system and in nutrients, as component valued for its high biological activity. Available at:
Dosage: calculated by vitamin C: 30-500 mg daily.


Vitamin C


Vitamin C (ascorbic acid) it is a vitamin soluble in body fluids, can be taken from foods (fruits and vegetables), or as drug derived synthetically. The largest of its resources can be found in broccoli, Brussels sprout, kale, black currant fruit and hawthorn, citrus fruits, tomatoes, Savoy cabbage, potatoes. In fact, intake of vitamin C of the food products does not limit the absorbed quantity. Vitamin C (ascorbic acid) is a potent antioxidant, it is an antitoxic, increasing the immune system due to the elimination of risk of bacterial contamination. Vitamin C prevents rupture of blood vessels, affects the blood cholesterol level. It substantially increases the absorption of iron. Inhibits the growth of cancer cells. Lowers stress levels.
Vitamin C deficiency causes abnormal development of connective tissue, cracking capillaries, abnormal calcification of bone tissue, impaired
absorption of iron, scorbutus. With the lack of vitamin C, all kinds of injuries do not heal up properly. Vitamin C deficiency can be caused by smoking; each cigarette is destroying up to 100 mg of vitamin C.
Dosage: The demand is 60-80 mg daily. It does not limit the ability to consume higher doses. Some side effects may occur only with longer
