Vitamin C, or ascorbic acid, is well-known for its role in immune function, collagen synthesis, and antioxidant protection — but it has nothing to do with sunlight exposure. This vitamin must be consumed through food sources such as citrus fruits, strawberries, bell peppers, and leafy greens. The body cannot produce vitamin C on its own and certainly not from sun exposure. While vitamin C is important for wound healing and protecting against oxidative stress, it is not synthesized by the skin or triggered by UV rays. Misidentifying vitamin C as the “sunlight vitamin” could distract from the need to ensure adequate vitamin D, which does depend on outdoor activity and skin exposure to UVB light. Proper understanding of each vitamin’s source and function helps you maintain better overall nutrition and health practices.
