What vitamin is primarily found in citrus fruits and is an antioxidant?

Citrus fruits are well-known for being rich in Vitamin C, which is also recognized for its potent antioxidant properties. As an antioxidant, Vitamin C helps to neutralize free radicals in the body, thereby protecting cells from damage that can lead to chronic diseases. Additionally, it supports the immune system, aids in the absorption of iron from plant-based foods, and is crucial for the maintenance of connective tissues through its role in collagen production. This vital nutrient can be found in high concentrations in fruits like oranges, lemons, limes, and grapefruits, making citrus fruits a key dietary source.

In contrast, Vitamin A is primarily found in dairy products and leafy green vegetables, while Vitamin D is synthesized by the body through sunlight exposure and found in certain fish and fortified foods. Vitamin E, an important fat-soluble antioxidant, is found in nuts, seeds, and green leafy vegetables. Thus, while these other vitamins have their own health benefits, none match the specific association of Vitamin C with citrus fruits and its role as a powerful antioxidant.
