Product Summary:

Cosequin® Optimized With MSM Joint Health Supplement

Cosequin Optimized With MSM is an excellent joint supplement that also helps ease discomfort from arthritis. Ideal for senior horses, it increases flexibility and decreases stiffness. The tasty apple-flavored powder is easily absorbed, and contains higher levels of active ingredients compared to original Cosequin, in response to reports that horses in work may benefit from higher levels of Glucosamine. The addition of high-quality MSM, an organic source of sulfur and a compound used by cartilage, is suggested by veterinarians to help manage joint health.


  • Veterinarian recommended joint health supplement
  • Convenient way to provide MSM along with the proven ingredients in original Cosequin
  • Improved joint health with higher levels of active ingredients
  • Tasty powder
  • Apple flavor horses love

can cosequin optimized be taken for human servere pain?
A shopper on Feb 2, 2015
BEST ANSWER: My vet thinks Cosequin is the best product out there for dogs and horses with the safest and most researched ingredients, however, I don't know if they are of human quality. I take glucosamine, but my doctors are skeptical of its worth. It is to help the joints not stop pain.
