What role do antioxidants play in tissue repair?

Antioxidants play a crucial role in tissue repair primarily by helping to decrease oxidative stress. During the process of tissue injury and subsequent healing, reactive oxygen species (ROS) are generated as part of the inflammatory response. While ROS can help to kill pathogens and facilitate healing, excessive levels can lead to oxidative damage to cells and tissues, complicating the repair process.

Antioxidants neutralize these reactive oxygen species, thus preventing or mitigating cellular damage. By scavenging free radicals, antioxidants protect the integrity of cells, promote healthier tissue regeneration, and support the overall healing environment. This reduction in oxidative stress is particularly important, as it helps to maintain cellular function, promote new cell growth, and improve outcomes during the repair process.

In contrast, the other options touch on aspects that do not align with the beneficial role of antioxidants in healing. For instance, increasing inflammation and pain is generally detrimental to healing, while promoting scarring suggests a negative outcome rather than improved tissue integrity. Lastly, the assertion that antioxidants are not relevant contradicts the established understanding of their protective function in healing processes.
