Abstract
In modern society, the development of functional foods that not only provide the body with essential nutrients but also help prevent various diseases is of particular importance. One of the most in-demand nutrients is vitamin D₃, which plays a key role in regulating calcium-phosphorus metabolism, strengthening bone tissue, supporting immunity, and reducing the risk of chronic diseases. However, insufficient sun exposure and dietary patterns in some regions contribute to vitamin D₃ deficiency in a significant portion of the population.
