How Does Pro Flex Work?

Pro Flex combines a superdose of hydrolyzed collagen with key joint-supporting ingredients to:

  • Reduce joint discomfort and friction
  • Boost joint hydration and flexibility
  • Protect your cartilage from wear and tear


By minimizing friction and supporting long-term joint health, Pro Flex helps your joints stay flexible and resilient.

You’ll feel the first benefits after 3 weeks of consistent use with improved comfort and mobility. Continued use strengthens these effects, helping you stay active through demanding training blocks.

Hydrolyzed collagen

Collagen is a protein naturally produced in the body, responsible for the health of 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.






Methylsuflonylmethane (MSM)

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


Boswellia

Boswellia is a powerful natural adaptogen that boosts joint health and flexibility. It also reduces joint pain and inflammation. As an adaptogen, boswellia works best after a loading phase of 6 to 8 weeks.


Hyaluronic acid

Hyaluronic acid keeps joints hydrated and cushioned, sustaining mobility and reducing stiffness.

Glucosamine sulphate

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




Chondroitin Sulphate

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

Vitamin C

Essential for collagen synthesis and joint tissue repair. Strengthens connective tissues and enhances the effectiveness of collagen supplementation.

Vitamin B6

Supports protein metabolism and reduces fatigue, ensuring efficient collagen utilization.

Vitamin D

Contributes to bone strength, calcium absorption, and proper muscle function, helping protect joints.

Recommended Use

Mix 3 scoops (20 g) with 250-400 ml of water.

The product is best taken between the two main meals during the day.

Tip: The product does not contain artificial substances, such as guar gum or xanthan gum, so mixing with water is a little more difficult. We recommend using a shaker or blender. It is best if the water is at room temperature.

Attention: Do not take if allergic to mussels, crabs, and other crustaceans!

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 :-)

Really good formula

Good taste and loads of benefits
Recommend to shake it in a shaker, a little bit hard to shake it smoothly.

Prodotto da 5 stelle

Inizialmente diffidente ho voluto provare per cercare di trovare un po di sollievo dal perenne dolore alle ginocchia provocato dopo ogni sessione di attività sportiva. Dopo appena una settimana di utilizzo ho dato la svolta alla mia vita. I problemi alle ginocchia si sono ridotti fino a scomparire migliorando sensibilmente il mio stile di vita e le mie sessioni sportive. Consigliato ad un sacco di amici e conoscenti con il mio stesso problema che stanno già ottenendo i primi ottimi e miracolosi risultati.

Ad averlo ricevuto!

Chi lo può sapere? Avete fatto una spedizione con un corriere che nn serve una zona che è normalmente servita da tutti i corrieri, poste comprese. Sono 10gg che hanno in ostaggio un ordine di oltre 100€, non ho a disposizione tutta una serie di prodotti che avrebbero dovuto sostenermi ed aiutarmi con questo gran caldo in un periodo di ferie in cui finalmente potersi allenare con più tempo, ed invece sto andando avanti a Gatorade. Qlcn di voi stà cercando di fare qlcs, ma senza nessun risultato, anzi sembra una presa in giro dopo l'altra. Delusissimo

Salve
Siamo spiacenti per questa esperienza, vi prego di inviarmi un'e-mail con il vostro numero d'ordine a irenej@4endurance.eu.
Provvederò a farle ricevere la spedizione il prima possibile.
Mi scuso ancora una volta, purtroppo ora in agosto ci sono alcuni ritardi dovuti alle vacanze GLS.

Durata prodotto

Ci vorrebbe un misurino per i 20 g. nella confezione ( consiglio) , e se devo assumere 20al g. la confezione mi dura 20 GG. Giusto? Mi conviene comprarne almeno un altro, quindi. Però prima lo provo e poi vediamo.

Ciao,

grazie mille per il tuo acquisto! Si certo una confezione dur per 20-21 giorni. Si consiglia di fare una cura completa di 60 giorni. Se avrai altre domande riguardo i nostri prodotti contattaci quando vuoi. Ti auguro buona giornata.
