    Potent, Clinically-Studied Key Ingredients

    New Flex contains proven joint-saving ingredients like:

    New Zealand Green Lipped Mussel

    Shown in trials to support cartilage and joint health in aging dogs. These “Green Treasures” from the sea are also rich in proteins, omega-3s, and antioxidants.

    MSM

    Methylsulfonylmethane supports connective tissue repair by contributing to collagen synthesis. MSM has also been shown to help with swollen joints in clinical trials. 

    AstaZine Astaxanthin

    A carotenoid antioxidant shown in studies to reduce swelling and improve energy in dogs. 

    Driphorm HiDHA

    A highly absorbable omega-3 that’s proven to decrease harmful molecules that can deteriorate joints.

    Egg Shell Membrane

    Believe it or not, the thin lining between the shell and egg white contains proteins like collagen that support cartilage. Even better, a study of 32 dogs found 95% of owners reported improved joint stiffness.

    Biotin Pure

    A special form of this super-important B-vitamin that’s essential for healthy bone matrix proteins like collagen. Supplementing supports bone and
joint integrity.

    Hyaluronic Acid

    A powerful compound that lubricates joints for smoother motion and acts as a cushion between bones. Clinical veterinary trials demonstrate it relieves joint discomfort. 

    Vitamin C

    Which is surprisingly uncommon in most dog’s diets, even though it’s critical for collagen production and joint shock absorption.

    Rose Hips Fruit

    Which is loaded with powerful bioflavonoids that support cartilage integrity and better mobility. 

    Frankincense

    An ayurvedic super-herb that acts on several overactive enzymes behind swollen joints and discomfort in dogs. 

    Hydrolyzed Chicken Collagen

    Supports collagen production in the body and helps rebuild connective tissue.

    • Michelle S, who has a
      10-year-old Lab, says:

      “Cooper used to lag behind me on our morning walks, but now he's by my side again, pulling on his leash ready to go!

      The difference has been amazing.”

    • Sam K in Seattle,
      Washington writes:

      "My 12-year old beagle Lucy had trouble jumping up on the couch and seemed to be slowing down. But thanks to FourFlex it's like she shed 5 years off her life! She's back to playing tug of war with her favorite rope toy and I couldn't be happier."

    • Mark T in Austin,
      Texas shares:

      "Bogey would whimper in pain anytime he tried to climb the stairs. After just 1 month on FourFlex, he bounds up and down the stairs again without any problem. It brings tears of joy to my eyes to see him moving comfortably."

    Meet Our Formulator

    TrueCanine’s products are formulated with the help of Mark Reese, an expert who has spent over 23 years studying cellular health and aging in mammals. Shortly after Mark’s beloved labrador retriever Lacey turned 8, he noticed big changes in her health and wellbeing.

    Lacey began to slow down, lost her energy, struggled on walks, and overall began to “act old.” It happened so suddenly, and despite trying numerous “solutions” Mark was unable to help Lacey get back to being her old self.

    After Lacey passed away, Mark couldn’t shake the feeling that maybe he could have done more to help her. Because of this, Mark threw himself into his research in an effort to understand everything he could about why our dogs’ bodies change for the worse.

    After hundreds of hours of studying, Mark realized that most dog owners are getting a raw deal when it comes to their pet’s health. That’s because even expensive dog food and pet supplement companies often use questionable ingredients that aren’t backed by real science. That’s why he started TrueCanine, to give pet owners across the U.S. a better option.

    Giving my baby more quality time.

    My GSD is fourteen and was starting to loose her fight with arthritis and age. All the meds I gave her from the Veterinarian didn’t really help. I ordered Wild Belly and Flex a month ago. At first I was skeptical and impatient that this would work. After one month I can report a total turn around in her health . She’s back climbing stairs , jumping on the couch and bed , and able to go for short walks again. I’m very thankful to you . I don’t know how it works but it’s amazing! Thankyou for giving her and me more time. She’s my Angel

    FAQ's

    How quickly will I see results with New Flex?

    Most pet owners report seeing improvements in their dog's comfort, mobility, and enthusiasm within 3-4 weeks. However, results can vary depending on your dog's age, size, and severity of joint issues. For best results, we recommend using New Flex consistently for at least 2-3 months.

    Is New Flex safe for my dog?

    Yes, New Flex is formulated with only natural, high-quality ingredients that are safe for dogs. It does not contain any stimulants, artificial flavors/colors, or preservatives. Our manufacturing facility is USA-based and FDA-registered. As with any supplement, consult your vet before use if your dog has a serious medical condition.

    What is your return policy?

    We offer a 90 day money back guarantee. If you don't notice a significant improvement in your dog's joint comfort and mobility, just return any unused portion within 90 days of purchase for a full refund (less S&H).

    How should I give New Flex to my dog?

    Simply sprinkle the recommended serving size over your dog's food once daily. New Flex has a natural chicken flavor dogs love. You can also mix into a bowl of water or treats. For best absorption, give with a meal.

    Can I give New Flex to my dog long term?

    Yes, New Flex is safe for long term daily use. The powerful joint supporting ingredients are most effective when given consistently. We recommend giving year-round to maintain healthy joint fluid, flexibility, and comfort.

    Does my dog need to be a certain age to take New Flex?

    New Flex is safe for dogs of all ages! However, if your pup is under 6 months old, we recommend speaking with your veterinarian before adding any supplements to their diet.

    My dog is a really picky eater…Will he like New Flex?

    New Flex is formulated with a delicious all-natural chicken flavor that even our pickiest four-legged customers love! We haven't met a dog that doesn’t like New Flex yet, but if yours is the one, then you’ll still be backed by our 90 Day Guarantee.

    What is your 90 Day Guarantee? 

    All of True Canine’s products are backed by our 90 Day 100% Money-Back Guarantee.
