Pro Flex 4Endurance Pro is a powerful formula that combines the effect of hydrolyzed collagen, MSM, boswellia, glucosamine, chondroitin, and hyaluronic acid.

The result is an extremely efficient supplement to boost the health, strength, and flexibility of your joints and ligaments, which also boosts the health and look of your skin, hair, and nails.

Pro Flex contains vitamin C, vitamin B6, and vitamin D to further enhance the synergy of its premium-quality ingredients.

Boost the health, strength, and flexibility of your joints!

Collagen is a protein naturally produced in your body, responsible for the health of your joints, bones, ligaments, and skin. Since its natural production decreases with age, supplementing collagen always makes sense. Hydrolyzed collagen in combination with vitamin C provides the best absorption and effect. Pro Flex contains top-quality bovine collagen type I and III.

MSM or organic sulfur boosts your immune system, stimulates collagen and glucosamine production, and increases the health of your skin, hair, and nails. It also has an anti-inflammatory and anti-oxidant effect.

Boswellia is a powerful natural adaptogen that boosts the health and flexibility of your joints. It also reduces joint pain and inflammation. As an adaptogen, boswellia works best when you give it time to load in your body (ideally 6 to 8 weeks).

Glucosamine is a natural compound that protects your joints and ligaments from exercise-induced wear and tear. It also alleviates joint pain and boosts the production of new tissues.

Chondroitin is a molecule that preserves the health of your cartilage, protects it from degradation, and boosts the production of new cartilage.

Hyaluronic acid sustains the mobility of your joints and keeps them hydrated. It also preserves the smoothness and flexibility of your skin.

Protect your joints from exercise-induced wear and tear!

  • Boost health, strength, and flexibility of your joints
  • Reduce joint pain and inflammations
  • Boost natural collagen production
  • Boost health and look of skin, hair, and nails

hard to mix

so hard to mix it even in hot water, and the typical collagen taste is always there

We recommend you mix Pro Flex with a shaker and I promise you will be surprised. The product is natural, with no added flavorings, so there is a taste of collagen, which is not a bad thing.

I finally can run volume now!

Before I took Pro Flex I had another supplement from another brand which in hindsight didn't work so well. Getting older (now 52) and spending many years at a desk I couldn't run without pain in my (below knee) joints, tendons, ligaments. Taking Pro Flex now for 2 weeks and I noticed the effect right away. Now am running 20+k and don't need 3 days of rest with trouble of getting out of bed in the mornings anymore :-)


Knees suffer a lot when running over obstacles, I use it more as a prevention!

Thanks, Natasa

My daughter bought this for me, the joint pain went away within 2-4 days and hasn't come back since. Great taste too!
