Vitamin D

The correct answer is: Vitamin C

Vitamin C is known for its role as a powerful antioxidant, which is crucial for protecting cells and DNA from oxidative stress and damage caused by free radicals. This protective function is important in maintaining cellular health and preventing age-related changes as well as various diseases. Antioxidants like vitamin C can help stabilize free radicals, reducing their ability to cause harm. Additionally, vitamin C is vital for the synthesis of collagen, which supports the structural integrity of tissues. This combination of antioxidant properties and role in collagen production underscores its significance in overall cellular health and repair mechanisms.
