Glucosamine for Dogs and Cats: What the Research Says

Joint supplements are among the best-selling pet health products. Glucosamine, chondroitin, and MSM are the three most common active ingredients.

Glucosamine and Chondroitin

These compounds are building blocks of cartilage. They are commonly used to support joint structure and mobility, especially in senior and active pets.

MSM

Methylsulfonylmethane (MSM) is a source of sulfur that supports connective tissue health.

What to Expect

Joint supplements typically take 4–6 weeks to show noticeable effects. Consistent daily use is important.

Conclusion

While not a replacement for veterinary care, quality joint supplements can be a helpful part of a mobility support plan.
