Collagen is a primary structural protein found in connective tissues throughout the body, including the intervertebral discs of the spine. The rationale for using collagen to support or treat spinal discs stems from its role in maintaining the structural integrity and hydration of the disc matrix, particularly in the annulus fibrosus and nucleus pulposus. Scientific interest has focused on the decline of collagen content and quality in degenerative disc disease, which is associated with back pain and impaired mobility.

Recent scientific studies have investigated the potential benefits of oral collagen supplements (hydrolyzed collagen peptides) and injectable collagen for spinal disc health. Some preclinical and early clinical research suggests that collagen supplementation may stimulate extracellular matrix synthesis, improve disc hydration, or slow degenerative changes, primarily in animal models or in vitro studies. A few small human trials have suggested modest improvements in pain or function in patients with chronic back pain, but these are often confounded by concomitant treatments and lack robust methodology.

Overall, the scientific evidence supporting collagen supplementation specifically for spinal disc health in humans is limited and of low quality. There are no large, high-quality randomized controlled trials demonstrating a clear clinical benefit. Most medical guidelines do not currently recommend collagen as a standard treatment for degenerative disc disease. Thus, the scientific justification exists primarily at the theoretical and early research level, warranting further investigation but not yet established as an evidence-based therapy.
