Glucosamine
Provides the raw building blocks your dog's body uses to maintain cartilage, supports synovial fluid production, the joint's natural lubricant, and helps ease stiffness.
What it actually is
- A natural compound your dog produces themselves. Production slows with age, which is when supplementation matters
- Sourced from shellfish or fermented plant material
What the body does with it
- Used to build glycosaminoglycans (The molecules that make cartilage springy and shock-absorbing)
- Feeds synovial fluid production, so the joint stays lubricated rather than grinding
Glucosamine works best alongside MSM, which is why PawStrong pairs the two.
MSM (methylsulfonylmethane)
What it actually is
An 'organosulfur compound' - A delivery system for bioavailable sulfur, the third most abundant mineral in your dog's body
What the sulfur is used for
- Sulfur bonds are what hold collagen and connective tissue (cartilage, tendons, ligaments) together
- Also used to make glutathione, the body's own antioxidant defence
- A visible bonus: sulfur also builds keratin, so owners often notice coat and claw condition improving first
