Top 10 Best Foods Rich in Vitamin B12: Boost Your Energy and Brain Health Naturally

Vitamin B12, also known as cobalamin, is an essential nutrient your body needs for nerve function, red blood cell production, and DNA synthesis. A deficiency can lead to fatigue, memory problems, and even nerve damage. Unlike other vitamins, B12 is mainly found in animal-based foods, making it crucial for non-meat eaters to find alternative sources.

If you’re wondering how to naturally increase your B12 levels through diet, this guide explores the top 10 best foods high in vitamin B12 that can help keep your energy levels high, your brain sharp, and your metabolism running smoothly.

1. Clams – A Powerhouse of B12

Clams are one of the richest sources of vitamin B12. Just 100 grams of cooked clams provide over 1,600% of the Daily Value (DV). They’re also packed with iron, protein, and omega-3 fatty acids, making them a nutritional powerhouse.

How to enjoy: Add steamed clams to pasta, soups, or enjoy them grilled with herbs and lemon.

2. Liver – Especially Beef or Lamb Liver

Liver is an old-school superfood, and for good reason. A single 100-gram serving of beef liver contains more than 3,000% of the DV for vitamin B12. It’s also loaded with vitamin A, iron, and folate, which support immunity and cell repair.

Tip: Choose grass-fed liver for the best nutrient quality. You can fry it lightly with onions or blend it into pâtés.

3. Sardines – Small Fish, Big Benefits

Sardines are small, oily fish that come packed with nutrients. One cup of canned sardines can provide over 300% of the DV for vitamin B12. They’re also an excellent source of omega-3 fatty acids, which support brain and heart health.

Preparation ideas: Eat them on whole-grain toast, in a salad, or mix them into pasta dishes.

4. Tuna – A Versatile Seafood Choice

Tuna is not only high in protein but also provides a great amount of vitamin B12. A 3-ounce serving of cooked tuna offers about 450% of the DV. It’s also rich in selenium and vitamin D.

Cooking tip: Use fresh tuna steaks for grilling or canned tuna for easy sandwiches and salads.

5. Salmon – Omega-3 and B12 Combo

Wild-caught salmon is another B12-rich food. A 6-ounce cooked salmon fillet contains more than 200% of the DV. Besides B12, it’s an excellent source of omega-3 fatty acids, vitamin D, and high-quality protein.

Healthy option: Bake or grill salmon with herbs and olive oil for a heart-healthy meal.

6. Fortified Cereals – Best Plant-Based Source

For vegetarians and vegans, fortified breakfast cereals are one of the best non-animal sources of vitamin B12. Some brands provide up to 100% of the DV per serving. Be sure to read labels to find those fortified with B12 (cyanocobalamin).

Best practice: Choose whole-grain, low-sugar cereals for added fiber and nutrients.

7. Eggs – Everyday B12 Source

Eggs, especially the yolks, are a convenient source of B12. One large egg provides around 10% of the DV. Though they don’t contain as much B12 as meat or fish, they’re still a valuable part of a balanced diet.

Breakfast idea: Boil, scramble, or poach eggs and combine them with veggies for a nutritious start to your day.

8. Milk and Dairy Products

Milk, cheese, and yogurt are not only high in calcium but also excellent sources of vitamin B12. One cup of whole milk contains about 46% of the DV. Yogurt and cheese (especially Swiss and mozzarella) also contribute good amounts.

Diet tip: Opt for organic or grass-fed dairy for added health benefits.

9. Chicken – Lean and Nutritious

Chicken, particularly the breast, is another lean protein that contributes to your B12 intake. A 3-ounce serving contains around 5%–10% of the DV. While it’s not as high as red meat or fish, it’s still beneficial, especially in combination with other B12 foods.

Meal idea: Grilled chicken salads or curries can be delicious and nutrient-rich.

10. Nutritional Yeast – Vegan-Friendly Option

Nutritional yeast is a popular vegan source of vitamin B12, especially when fortified. Just 1 tablespoon of fortified nutritional yeast can contain up to 100% of the DV. It has a cheesy, nutty flavor and is ideal for adding to plant-based meals.

Serving idea: Sprinkle it on popcorn, pasta, or salads for a cheesy flavor and B12 boost.

Final Thoughts: Why You Need Vitamin B12-Rich Foods

Getting enough vitamin B12 is crucial for your energy levels, brain function, and mood regulation. Whether you’re a meat-eater, vegetarian, or vegan, there are plenty of delicious and accessible ways to include B12-rich foods in your diet. For those who have trouble absorbing B12 from food (e.g., older adults or people with digestive issues), a supplement or B12 injection may be necessary—consult your doctor if you’re unsure.
