Vitamin B12 is an essential nutrient that plays a crucial role in various bodily functions, including nerve function, DNA synthesis, and red blood cell formation. Ensuring adequate intake of vitamin B12 is vital for maintaining overall health and preventing deficiency. Understanding which foods are richest in this vitamin can help you make informed dietary choices to meet your nutritional needs.
Clams stand out as the food with the highest concentration of vitamin B12. A 3-ounce serving of cooked clams provides a remarkable 84.1 mcg of vitamin B12, exceeding the daily value by a significant margin. Beyond their exceptional B12 content, clams are also a good source of potassium, an important electrolyte for maintaining healthy blood pressure and muscle function.

Seaweed is another impressive source of vitamin B12, particularly dried purple laver. Depending on the type, 100 grams of seaweed can offer between 30 to 60 mcg of vitamin B12. This makes seaweed a valuable plant-based option for those seeking to boost their B12 intake. Furthermore, seaweed is rich in iodine, a mineral essential for proper thyroid function, which regulates metabolism and other vital processes.
Oysters are also high on the list of B12-rich foods. A 3-ounce serving of cooked oysters delivers 24.5 mcg of vitamin B12. Oysters are not only a great source of B12 but are also exceptionally high in zinc, a mineral crucial for immune system support, wound healing, and overall growth and development.

Nutritional yeast, with its cheesy, nutty flavor, is a powerhouse of B vitamins, including B12. Just 3 tablespoons of nutritional yeast provide 24 mcg of vitamin B12, making it an excellent vegan-friendly source. Beyond B12, nutritional yeast is also packed with other B vitamins like B1, B2, B3, and folate, contributing to energy production and overall well-being. It’s also a good source of protein.
Mussels are another shellfish that contributes significantly to B12 intake. A 3-ounce serving of cooked mussels contains 20.4 mcg of vitamin B12. Mussels are not only rich in B12 but also offer a variety of other nutrients, including protein, potassium, vitamin C, and omega-3 fatty acids, supporting heart health and reducing inflammation.

Crab, while slightly lower in B12 compared to clams, oysters, and mussels, still offers a notable amount. A 3-ounce serving of crab meat provides 7.6 mcg of vitamin B12. Crab is also a good source of vitamins A, B, and C, as well as magnesium and zinc, contributing to various aspects of health, including immune function and nerve function.
Sardines are small, oily fish that are surprisingly rich in vitamin B12. A 3-ounce serving of sardines contains 7.6 mcg of vitamin B12. Beyond B12, sardines are packed with calcium, vitamin D, and omega-3 fatty acids, supporting bone health, brain function, and heart health.
Trout is a fatty fish that offers a good amount of vitamin B12. A 3-ounce serving of wild rainbow trout provides 5.4 mcg of vitamin B12. Trout is also an excellent source of vitamin D and omega-3 fatty acids, both of which are beneficial for brain health and reducing inflammation in the body.
Salmon, another popular fatty fish, is also a valuable source of vitamin B12. A 3-ounce serving of cooked sockeye salmon contains 3.8 mcg of vitamin B12. Salmon is rich in protein, vitamin D, and heart-healthy omega-3 fatty acids, making it a nutritious addition to any diet.

Other animal products like tuna, haddock, beef, milk, yogurt, eggs, chicken, and turkey also contribute to vitamin B12 intake, although in lesser amounts compared to the top sources mentioned above. Fortified breakfast cereals are another option, particularly for vegetarians and vegans, to obtain vitamin B12.
For individuals who do not consume animal products or have difficulty absorbing B12 from food sources, vitamin B12 supplements are available. It’s important to consult with a healthcare provider before starting any supplements to determine the appropriate dosage and ensure no potential interactions with medications.
Maintaining adequate vitamin B12 levels is crucial for overall health. By incorporating B12-rich foods like clams, seaweed, oysters, nutritional yeast, mussels, and fatty fish into your diet, you can effectively meet your daily B12 requirements and support optimal bodily function.
