Some vitamins can be produced by the body naturally, while others need to be obtained from food sources.
Vitamin D is a vitamin that your body can produce naturally when the skin is exposed to UV radiation in sunlight. This process allows the body to synthesize the vitamin without solely relying on dietary sources.
On the other hand, most other vitamins, such as Vitamin A, need to be obtained from foods since the body cannot produce them. For example, vitamin A can be synthesized from the precursor ß-carotene found in orange vegetables like carrots.
Vitamins are essential nutrients that play various roles in maintaining good health, with some being synthesized in the body from precursors or by bacteria, while others are derived from a diet rich in fruits, vegetables, meat, and fish.
