                                While most people are familiar with vitamins D2 and D3, which are crucial for human health, a lesser-known form is vitamin D5. Unlike its well-documented counterparts, vitamin D5 does not play a significant nutritional role for humans and is not available as a standard dietary supplement. Instead, it functions primarily as a scientific analogue used in laboratory research.
