Owner reaction: “Finally, this is something I’ve been looking for for a long time”.

FLEX by GOLDMEDICS is double supporting:

1. At the level of the chondrocytes: Chondrocytes ensure a continuous breakdown and reconstruction of cartilage. This is a natural and necessary process. Normally, destruction and reconstruction are in balance. Research has shown that certain nutrients can favorably influence this balance.

2. FLEX by GOLDMEDICS contains essential elements for rebuilding damage. The cartilage will then produce better quality/viscous synovial fluid, so that everything is more shock-absorbing, resulting in a smoother moving animal. FLEX is also used preventively to maintain healthy tendons and joints. You can learn more about it by clicking on the arthritis and limping pages.

There is a major result : Research shows that after 3/4 weeks a clear improvement is noticeable and after 6 months 80% of dogs are again able to jump like on the sofa or in the car.

Only ingredients that have a scientifically proven effect and achieved visible results in our practices are used.

Acetylglucosamine supports the management of pain, swelling and stiffness and is more efficient than the commonly used glucosamine because glucosamine must first be converted by the body to acetylglucosamine before being active. Acetylglucosamine is one of the 8 essential amino sugars in the body; it is the building block for hyaluronic acid and a crucial element for the biosynthesis of glycoaminoglycans necessary for the synthesis of bone, cartilage, tendons, ligaments and other connective tissues.

Sodium hyaluronic acid functions in the joint as a shock absorber and lubricant. Hyaluronic acid also promotes the synthesis of proteoglycans, the main factor of cartilage elasticity. We chose a molecular size that is better absorbed into the body and has been shown to migrate effectively to the joint.

Two different collagen peptides are added. Seventy percent of cartilage is made up of collagen. Research with these peptides showed improvement in flexibility and vitality. They meet the increased need for nutrients for the musculoskeletal system under heavy load and in the growth phase.

In people who have taken the supplement for 3 months compared to people who have taken a placebo (similar product but without active ingredients) during those 3 months, the effect of the supplement on the new repair of the cartilage is clear. The mechanism was illustrated ex vivo on canine chondrocytes by a decreased degradation and an increased build-up. More info here

Bamboo extract contains the highest level of natural silicon of all plant extracts. Silicon is known to play a role in bone mineralization, collagen synthesis, hyaluronan synthesis and stimulation of the immune system.

MSM reduces oxidative stress and has a soothing effect on inflammation. It is also an important organic sulfur compound. Various hormones, enzymes, proteins, the structure and firmness of cartilage, skin and hair depend on the concentration of sulfur in the body. Sulfur is also one of the main components of collagen, present in joints, tendons and ligaments. Here you will find more information about it

In addition, Curcumin is also added in an exceptionally absorbable form. Curcumin is a very powerful antioxidant and helps to soothe inflammation. Curcumin is the pure active ingredient; this in contrast to Curcuma (the root itself) which contains only 0.6 to 5% curcumin on dry matter. More info here

And finally, FLEX by GOLDMEDICS  also contains a dose of prebiotics. Prebiotics are substances that have a beneficial effect on the flora of the gastrointestinal tract; because they are substrate (food) for the good flora and ensure that “bad” flora is kept under control. The microbial intestinal flora is currently often described as the “forgotten” organ. There are more bacteria in the gastrointestinal tract than cells in the body. It is one of the finest examples of synergy between guest and host after centuries of evolution. A direct beneficial connection between the gut microbiome and the joints has been demonstrated.

An interesting side effect is the beneficial effects that FLEX by GOLDMEDICS exerts on skin and coat.

Cat and small dog (<10kg) 5ml/day; medium (10 to 25 kg) and large dogs (>25 kg) 7.5 ml/day.
So a 500 ml bottle contains 100 daily doses for a small dog and 66 doses for the medium and large; a bottle of 1 liter is double that.

If assistance with cartilage reconstruction is necessary, the administration should preferably be continued for a minimum of 12 weeks.

FLEX by GOLDMEDICS for dog is available in 0.5 liter and 1 liter. The 0.5 liter bottle contains 66 daily doses for large and medium dogs and 100 daily doses for small dogs.

To be mixed with food or via a syringe in the mouth.

TIPS: If you want to see results even faster:

  1. Apply Flex to the food and let it soak in for a few hours before feeding.
  2. Give an even larger amount at the start. You can safely dose 5 times more per day.

If your dog is clearly in pain, you can opt for a combination of FLEX by GOLDMEDICS with DOLO-LESS DOLO-LESS GOLD for Dogs will help to ease the initial pain.
