    Product Overview

    Extra Strength Healthy Hip & Joint (formerly GlycoFlex 3) targets senior dog mobility using Green Lipped Mussel. While the NASC seal confirms quality, the strong marine smell and reliance on internal research are notable downsides. Its transparent, high-potency labeling makes it a strong consideration for advanced joint support.

    Key Benefits

    • Manufacturer-funded study reported a 41% increase in hind leg strength.
    • Supports joint comfort and healthy inflammation response.
    • Provides nutrients for cartilage maintenance and joint structure.

    Pros

    • Transparent ingredient labeling lists exact dosages
    • NASC quality seal confirms strict safety audits
    • Includes clinical levels of Green Lipped Mussel

    Cons

    • Strong marine odor is unpleasant
    • Efficacy claims rely on older internal research
    • Chews can sometimes arrive hard or stale

    Bottom line

    This high-dose supplement targets stiffness and aging joints. While expensive and smelly, the NASC safety seal and transparent ingredients offer verified value. It is best suited for seniors or working dogs, though buyers should note the efficacy data comes mainly from internal brand research.

    • Strong, lingering fish odor

    Bottom line
