It contains up to 4 active substances necessary for the proper functioning and regeneration of joints: collagen, vitamin C, glucosamine and chondroitin. The collagen contained in the product is collagen hydrolyzate, i.e. the hydrated form of pure collagen. Its characteristic feature is good bioavailability, thanks to which it has a strong effect.

FlexActiv EXTRA stimulates the body to produce collagen in its natural form, which is the main component of connective tissue. It is the basis for the structure of tendons, ligaments, cartilage, bones, spine components and blood vessels. Collagen also participates in the reconstruction after injuries and regenerates. At the same time, it supports prevention, preventing connective tissue damage.

In addition, FlexActiv EXTRA has been enriched:

• vitamin C: belonging to organic compounds from the group of polyhydric alcohols, whose action is necessary for living organisms. Vitamin C acts as an activator of many enzymes in the human body, including for the synthesis of neurotransmitters and corticosteroids. It also helps in the proper production of collagen.
• glucosamine: an amino sugar naturally found in our body in FlexActiv EXTRA occurs in the form of glucosamine sulfate.
• chondroitin: a chemical compound that belongs to mucopolysaccharides and is endogenous in nature, so it is produced by our body.

During periods of increased physical exertion, heavy joints or overweight and in the elderly, glucosamine production in the body decreases. The result is that the joints do not work properly, causing pain and mobility problems. In FlexActiv EXTRA occurs in the form of sulfate, it is the form with the highest efficiency. This relationship is extremely important due to the elimination of the unpleasant feeling of friction between articular surfaces. Chondroitin naturally stimulates the body to produce synovial fluid.

The product relieves pain and disability caused by degeneration of the joints. It has a positive effect on the condition of the joints, as well as building blocks of compounds found in articular cartilage. It participates in the synthesis of proteoglycans that strengthen and even regenerate affected joints.
