Synopsis: Collagen is a structural protein that plays a crucial role in the integrity and strength of connective tissues, including ligaments and tendons, which are commonly affected in sprains. The rationale for using collagen supplements or therapies in the context of sprains is based on its potential to support tissue repair and regeneration. Some scientific studies have explored the effects of oral collagen hydrolysate supplementation on joint health and connective tissue healing. For instance, research has shown benefits in reducing joint pain and potentially supporting tendon and ligament health, primarily in athletes and older adults. However, robust clinical evidence specifically addressing acute sprain recovery is limited. Most available studies are small, short-term, or focus on related conditions such as tendinopathies or general joint pain rather than acute ligament injuries like sprains. Animal studies suggest that collagen supplementation can improve collagen synthesis and tissue remodeling after injury, but these findings have not been consistently replicated in large human trials for sprains. In summary, while there is a plausible scientific basis and some preliminary evidence to suggest collagen may aid in the healing of sprained ligaments, high-quality clinical trials are needed to confirm its efficacy. Therefore, the evidence supporting collagen's use for sprains is modest and rated as 2 out of 5.
