Equisearch suggests using a supplement that provides 6,000 to 10,000 milligrams of glucosamine and 1,250 to 5,000 milligrams of chondroitin per day. A brand that has been on the market for a long time is more likely to be effective.
Because there is no regulation of equine joint supplements, some may not contain the ingredients they claim to.
For horses experiencing acute flare-ups or ongoing heat and swelling, try a supplement with hyaluronic acid. The full dose of hyaluronic acid is 100 milligrams per day. Unsaponifiables derived from soy or avocados and cetylated fatty acids may help protect cartilage from damage.
