“Equin Joint Foundation supplements are a game-changer for senior horses. They’re formulated with science-backed ingredients I trust”
Dr. Deborah Wilson
Vet Consultant to Equin®
In a 59-day study of racehorses, the
horses given an oral Hyaluronic Acid
supplement - the kind you feed,
not inject - improved on every
measure of soundness. They also
needed the vet less often than the
horses that got nothing.
150-day controlled trial
"After 5 months, horses given
collagen-building nutrients
improved more in pain and joint
flexibility than horses given
glucosamine and chondroitin."
Horses given a structural joint
supplement moved their hocks
through a greater range of motion
- at both walk and trot - than
horses that received no supplement.

Frequently asked questions
Simple: feed Equin daily, at the full label rate, for 60 days. If your horse isn't moving better at the end of it, email us between day 60 and day 75 with your order number and a photo of the used container, and we'll refund what you paid for the product. Nothing to send back - keep the opened bag or bin it. The guarantee applies to a 60-day supply ordered directly from shopequin.com, one claim per customer, on your first order. Full terms are on our 60-Day Soundness Guarantee page.
Equin feeds the structures around the joint - bone, connective tissue, cartilage and synovial fluid - and many of our customers feed it to horses managing a diagnosed condition for exactly that reason. But we want to be straight with you: Equin is a nutritional supplement, not a veterinary treatment. It does not treat, cure or reverse navicular, osteoarthritis or any other diagnosed disease, and anyone who tells you a supplement will is selling you something. The right move: show the full ingredient label to your vet and ask whether it fits your horse's management plan. Every ingredient and dosage rate is printed on the label, so it's an easy conversation.
Once daily with feed. For best results, don't wait for stiffness to appear - the earlier you start feeding the structural foundation, the more you're ahead of the problem. If your horse is already showing signs of discomfort or reduced mobility, start as soon as possible. Consult your vet for a tailored approach.
Most horse owners notice easier movement within the first 4-6 weeks. Full structural support compounds over 3 months of daily use. That's also why our guarantee runs 60 days and not 14 - we're asking you to give the formula the time it actually needs, and in exchange we carry the risk.
Yes. Daily training creates micro-damage in tendons and ligaments that needs to repair overnight. Equin supports that repair cycle, reduces connective tissue downtime, and maintains the synovial fluid and bone density that hard work depletes over time.
Equin contains 0 banned substances and is suitable for competition horses. Always check with your governing body if competing at elite level. Equin is formulated for horses aged 2 and over.
Just continue with the normal daily scoop. Don't double up - consistency over time is what drives results. The occasional missed day won't disqualify you from the 60-day guarantee either.
Rarely an issue: Equin is alfalfa-based, so it smells and tastes like feed, not chemistry, and most horses clean the bucket. If yours is a fussy eater, mix the scoop into a slightly damp feed so the powder binds instead of sifting to the bottom, and introduce it gradually over the first few days.
