What vitamins have shellfish in them?

Shellfish themselves don't "contain" vitamins in the way that you might find vitamins in a pill. They are a source of many essential vitamins and minerals, but those nutrients are naturally occurring within the shellfish.

Here are some of the key vitamins and minerals found in shellfish:

* Vitamin B12: Shellfish are an excellent source of vitamin B12, which is crucial for red blood cell production and nerve function.

* Vitamin D: Some shellfish, like oysters, are a good source of vitamin D, which is essential for bone health and immune function.

* Iron: Shellfish are high in iron, which is necessary for carrying oxygen throughout the body.

* Zinc: Shellfish are also a good source of zinc, which is involved in immune function, wound healing, and cell growth.

* Selenium: This mineral, important for thyroid function and antioxidant protection, is found in good amounts in shellfish.

* Omega-3 fatty acids: Shellfish, particularly oysters, are a good source of omega-3 fatty acids, which are beneficial for heart health and brain function.

It's important to note that the specific vitamin and mineral content of shellfish can vary depending on the type of shellfish, the season, and the environment in which it is harvested.
