is a synergistic herbal joint supplement for horses, handcrafted in small batches by Sustenance Herbs of Kittery, Maine. It pairs shellfish-derived glucosamine with a certified-organic blend of Boswellia serrata, turmeric, Devil's Claw, ginger and Solomon's Seal root, plus absorbable vitamin C from Amalaki, to support joint comfort, mobility and flexibility. The 1,600 mg-per-scoop proprietary blend carries no fillers, no bulk agents and no synthetic additives—only research-backed botanicals and superfoods chosen for how they work together. It is the kind of formula owners reach for when an aging knee, a stiff stifle or a hard-working joint needs daily, food-grade support.
Equine Joint Works™ is built to support a horse's whole musculoskeletal system rather than a single joint. Glucosamine HCl and natural antioxidants are blended to support joint lubrication and to help maintain healthy cartilage, connective tissue, ligaments and tendons. The herbal side leans on potent phenolics and enzymes—Boswellia serrata, Curcuma longa (turmeric), Devil's Claw and ginger root—that the company formulates to help reduce oxidative stress and free-radical formation while promoting circulation and the structural integrity of the joints.
Around that core sit adaptogenic and restorative herbs: Ashwagandha and Eleuthero root for resilience, Solomon's Seal root for connective-tissue support, Alfalfa leaf and Hemp Hearts as nutrient-dense superfoods, and Amalaki as a source of absorbable vitamin C. Every botanical in the blend is certified organic, with Solomon's Seal responsibly and ethically wildcrafted.
Sustenance Herbs has handcrafted its pet and horse supplements in small batches in Kittery, Maine since 2008. The promise printed on every tub is simple: no fillers, no bulk agents and no synthetic additives, ever. Where many joint products dilute active ingredients with cheap carriers, Equine Joint Works™ puts the full 1,600 mg per scoop toward the working blend—human-grade, certified-organic, Non-GMO herbs and superfoods.
"I have been using this product for 3 years to keep my super senior happy. It makes a big difference for his stifles!" Shelley P.
"My QH has arthritic knees. He does very well on this supplement." Gail S., on Rico, a 28-year-old Quarter Horse
That purity is backed by process. Sustenance Herbs retains samples of all raw ingredients with Certificate of Analysis documentation, has finished products independently lab-tested to verify label claims and screen for contaminants, and has been an audited member of the National Animal Supplement Council (NASC) since 2011—displaying the NASC Seal of Quality on its products. For owners who read every label, it is the difference between a guess and a known quantity.
Equine Joint Works™ is fed by weight, twice daily, with one scoop equaling one tablespoon. Horses up to 500 lbs take half a scoop twice daily; horses from 501 to 1,100 lbs take three-quarters of a scoop twice daily; and horses 1,101 lbs and up take a full scoop twice daily. To let a horse adjust to the herbs, Sustenance Herbs recommends starting at about 30% of the target dose and increasing gradually to the full amount over the first week.
The supplement comes in two sizes—a 1 lb container and a 2 lb container that holds 120 scoops, roughly a 60-day extra-support supply or a 120-day maintenance supply. Subscription delivery is available with savings that scale from bi-monthly up to weekly. Note that, due to state legislation, Equine Joint Works™ cannot be shipped to California or Vermont.
