  • Joints – Osteoarthritis, Rheumatoid Arthritis, Gout
  • Bones & Teeth
  • Nutrients – helps in the absorption of calcium and phosphorus

    Feature Ingredients

    • Glucosamine Sulfate helps to promote flexibility and mobility to the joints.
    • Nutri Flex also includes collagen, MSM, bromelain and other natural anti-inflammatory support.
    • Supreme formula has added parsley, celery, dandelion, hyaluronic acid, and more.

    The health of your joints is impacted by daily wear and tear; injuries; and decades of oxidative stress. The key natural solutions are provided in this all-in-one daily supplement.

    • Glucosamine is a well-researched component of glycosaminoglycans and proteoglycans that help trap water in the matrix of cartilage, to promote flexibility and resilience needed to function properly.1 It is an anti-inflammatory, it may support cartilage integrity by modulating synthesis of cartilage structural components by chondrocytes and it plays a crucial role in promoting joint lubrication.2-4
    • Collagen is the most abundant protein in mammals and is the main structural protein of connective tissues throughout the body. Hydrolyzed collage helps to reduce the pain associated with osteoarthritis.5-8
    • MSM (methylsulfonylmethane) a sulfur-containing compound may reduce inflammation, pain, and the degeneration in joints associated with OA (osteoarthritis).9-11
    • Bromelain is a mixture of enzymes found in pineapples that has anti-inflammatory properties. It helps to reduce inflammation, muscle soreness, muscle stiffness, symptoms of OA, and nasal swelling comparable to the commonly used NSAID (non-steroidal anti-inflammatory drug) Voltaren (diclofenac).12,13
    • Parsley contains the flavonoid luteolin in which early research suggests has anti-inflammatory properties that may help reduce pain and stiffness in joint health.14
    • Celery is not only good to eat as a snack, but research suggests that it may also help to reduce inflammation associated with arthritis.15
    • Devil’s claw contains plant compounds called iridoid glycosides, which have been shown to suppress inflammation in test-tube and animal studies.16 It may help reduce pain and inflammation associated with OA and gout.17
    • Dandelion is a herbal that helps support liver detoxification.
    • Curcumin has potent anti-inflammatory properties. Multiple research studies have found that it may help relieve the pain and symptoms associated with OA.18 In one study, it was found that curcumin may also slow the progression of OA.19
    • Boswellia has been found to have potent anti-inflammatory properties.20 It’s biological activity is believed to be linked to the boswellic acid that it contains. Boswellia may also help alleviate asthma, arthritis, and Crohn’s disease.20-22
    • Hyaluronic acid is the primary natural polymer compound present in the synovial fluid of joints. It helps to create a viscous, cushioned environment for joint cartilage that helps to prevent friction. In addition to improving joint lubrication, supplemental hyaluronic acid appears to stimulate the body’s generation of new hyaluronic acid, while alleviating pain and inflammation.23-27
    • Vitamin D is a fat-soluble vitamin that plays a role in bone health, cell growth, immune function, and fighting inflammation.28,29 In a recent study it was found that the group with consistently sufficient vitamin D status had less tibial cartilage loss and improved physical function compared to those with insufficient levels of vitamin D.30,31
