Key ingredients of Flex

Vitamin C

Takes part in synthesis of collagen and cartilage. Collagen is a protein that is main compound of elements such as ligaments, tendons and joint capsules. It makes them more flexible, reducing the risk of injury.

Vitamin E

Beside being antioxidant, it reduces joint inflammations. It also enhances look of the skin, which ist particullary important for women.


Higher doses have anti-inflammation effect that supports the action of vitamin E. 

Glucosamine hydrochloride

Is necessary in synthesis of proteoglycans and glucosaminoglycans in the body. It causes the regeneration of cartilage by chondrocytes. Glucosamine is made of glucose and glutamine and is naturally produced by the body, but when body is under heavy resistance training protocol, its amount is not adequate to efficiently regenerate joints.  The supplementation of glucosamine is important preventive treatment and it also relief the pain after injury. Flex formula contains glucosamine hydrochloride, which is more efficient that glucosamine sulphate. Approx. 85% of glucosamine  HCL is pure glucosamine with very good bioavailability. Glucosamine is also an component of synovial fluid, so its supplementation dilute synovial fluid enhancing the „greasing” inside the joint.

Linseed oil

Very efficient in fighting any inflammatory state, including joint inflammations. Linseed oil is rich in omega-3 fatty acids (alpha-Linolenic acid ), that has documented anti-inflammatory effect. Flex contains 55% of linseed oil, which is enough of EFA to support joints. Linseed oil also contains linoleic acid , which belongs to omega-6 group. Both omega-3 and omega-6 fatty acids modulates synthesis of prostaglandins. Prostaglandins are tissue hormones that are quickly metabolized into inactive compounds and while active, they regulate cell activity. Prostaglandins regulate blood preassure, Inflammatory response, insulin sensitivity, immune system, anabolic/catabolic processes and literally hundreds of other processes. Omega-3 fatty acids are responsible for creating anti-inflammatory prostaglandins, while omega-6 fatty acids produce pro-inflammatory prostaglandins. Moreover linseed oil has a lot of pro-health properties so it’s a must in supplementation of every athlete.

Ginger root extract (10:1)

Ginger is known for its warming properties, as well as anti-inflammatory and digestion enhancing effect. It slows down biochemical processes related to inflammatory state and inhibits inflammation regulators. 


Just like ginger it has an anti-inflammatory effect by inhibiting of histamine release, to reduce swelling.

Chondroitin sulfate

Compound important in maintaining connective tissue integrity and ensures proper amortization due to water binding properties.  Its effects are similar to glucosamine, so these two compounds are agood match as the support their effects. Chondroitin has very good bioavailability, shows analgesic properties, regenerates connective tissue and increases joint mobility, which is important during recovery period after the injury.

Boswellia Serrata Extract

One of few clinically tested plant extract with documented positive effect on joints. This extract contains boswellic acids that showed strong anti-inflammatory effect, comparable to NSAID drugs, particularly when it comes to joints. 


Inhibits histamine release reducing swelling and allergy symptoms. Moreover it enhance blood flow by tighten capillaries. It protects breakdown of hyaluronic acid, which is also an ingredient of Flex.


Pineapple juice enzyme. It reduces swelling and acts anti-inflammatory which makes it great addition to Flex.

Hyaluronic acid

It is a mucopolysaccharide that connects collagen and elastin. Supplementation of hyaluronic acid maintain its proper molecular mass in synovial fluid increasing its viscosity and inhibits inflammation in the joint area. It also has analgesic effect, can increase immunity to mechanical injury and increase absorption of nutritional compounds. Women will find interesting, that hyaluronic acid can enhance skin state and unwrinkle by ensuring proper hydration of skin. Hyaluronic acid has extraordinary water binding properties.
