A Rare Food Source of Vitamin D

Vitamin D operates as a hormone rather than a typical vitamin, and it is essential for human health. Vitamin D improves bone health and modifies cells, immunological function, and inflammation, among other things. It also has anti-cancer capabilities due to its connection with apoptosis. The sun is the finest source of vitamin D, but you can also receive it through your food, and oysters are a good source.

For example, 100 grams of oysters provide 320 IU of vitamin D, which is roughly 80% of the RDI. As a result, oysters are an excellent potential source of vitamin D for persons who do not receive enough sun exposure or who live in areas with long and gloomy winters.
