Rating (out of 5): 3

Vitamin C (ascorbic acid) has a scientifically supported role in injury recovery, particularly in wound healing and tissue repair. Its use is primarily justified by its biochemical functions: Vitamin C is essential for the synthesis of collagen, the main structural protein in skin, tendons, and ligaments. Collagen formation is critical for the repair of connective tissue following injuries such as cuts, burns, and fractures. Several studies demonstrate that Vitamin C deficiency impairs wound healing, and supplementation can improve outcomes, especially in those with marginal or low baseline levels. For example, a 2017 review in Nutrients highlights Vitamin C’s role in each phase of wound healing, from inflammation to tissue remodeling.

Clinical trials have explored Vitamin C supplementation in various injury settings. Some data indicate it may reduce oxidative stress and inflammation after musculoskeletal injuries and surgeries, though results are mixed regarding its benefit in well-nourished populations. High-dose Vitamin C has also been investigated for reducing the risk of complex regional pain syndrome after fractures, showing some promise. However, evidence is less robust for its use in accelerating muscle recovery after exercise-induced injury.

In summary, Vitamin C’s use for injury support is grounded in its known biochemical effects and supported by moderate-quality evidence, especially in individuals at risk of deficiency. Routine supplementation in healthy, well-nourished individuals is less clearly beneficial, but it remains a widely accepted adjunct in clinical nutrition related to injury recovery.
