Although collagen and glucosamine are both commonly used to promote joint health, they are completely different substances and, therefore, can lead to very different results.
Glucosamine is a natural chemical found in the fluid around the joints and accounts for 1% of cartilage (1). Supplemental glucosamine is usually sourced from shellfish or synthetically made in labs (1)
As the body's primary protein, collagen plays a vital role in the composition of joint structure, as well as most of the body's tissues, such as muscle, bone, skin, hair, and nails. Landish hydrolyzed marine collagen is sourced from the by-products of wild-caught fish.
In terms of their effect on joint health, glucosamine acts more like a lubricant in the joints, whereas collagen has been shown to help with osteoarthritis by having a protective effect on cartilage, improving cartilage regeneration, and reducing joint pain (2)(3).
Landish Pure Canadian Marine Collagen and our Marine Collagen Beauty Blend are Health Canada approved for reducing joint pain over a minimum period of 5 months of daily supplementation.
