Yes, natural foods do contain methylated B12. Animal products like meat, fish, eggs, and dairy have methylcobalamin, which is the active form your body uses right away. This article will show you the best food sources of methylated B12, how to add them to your meals, and what you need to know about getting enough of this important vitamin.
What Is Methylated B12 and Why Does It Matter?
Methylcobalamin is a natural form of vitamin B12 found in your body and in animal foods like meat, fish, seafood, and dairy. It’s different from the fake kind called cyanocobalamin that you find in most cheap supplements.
Your body likes methylcobalamin because it’s ready to use. No extra work needed. The two bioactive forms of vitamin B12 are methylcobalamin in your cells and adenosylcobalamin in your mitochondria.
The Difference Between Natural and Fake B12
Cyanocobalamin is a synthetic form of vitamin B12 that’s not found in nature. When you eat foods, you get the natural forms. When you take most cheap vitamins, you get the fake kind.
Here’s what makes methylated B12 special:
- Works right away in your body
- Helps your nerves stay healthy
- Keeps your brain sharp
- Makes red blood cells
- Helps with energy

Best Animal Foods Rich in Methylated B12
Animal foods are the top sources of natural methylated B12. Let’s look at the best ones.
Organ Meats: The B12 Champions
Lamb’s liver provides about 3,571% of the daily value for vitamin B12 in a 3.5-ounce serving. That’s a huge amount!
Top organ meats for B12:
- Lamb liver – 65 mcg per 3 ounces
- Beef liver – over 60 mcg per 3 ounces
- Chicken liver – 14.3 mcg per 3 ounces
- Lamb kidneys – about 3,000% daily value per serving
- Beef kidneys – similar to lamb kidneys
These foods pack the most punch. You only need a small amount to meet your needs for days.
Shellfish: Ocean’s B12 Treasure
Shellfish are amazing sources of methylated B12. You can get over 7,000% of the daily value in 20 small clams.
Best shellfish choices:
- Clams – 84 mcg per 3 ounces
- Oysters – 24.5 mcg per 3 ounces
- Mussels – 20.4 mcg per 3 ounces
- Crab meat – high amounts
- Scallops – good amounts
Even the water from cooked clams has lots of B12. Don’t throw it away!
Fish: Tasty B12 Sources
Fish gives you methylated B12 plus healthy fats. A 6-ounce tuna fillet provides 18.5 mcg of vitamin B12.
Fish high in B12:
- Salmon – 4-5 mcg per serving
- Mackerel – 15-16 mcg per serving
- Sardines – 8-13 mcg per serving
- Trout – 4-5 mcg per serving
- Tuna – high amounts
Canned fish works great too. Sardines in a can still have tons of B12.
Beef and Red Meat
Beef and lamb are solid B12 sources. A 3-ounce serving of beef steak provides 6.9 micrograms of vitamin B12.
Red meat options:
- Beef steak – 2-7 mcg depending on cut
- Ground beef – 2-3 mcg per serving
- Lamb – 2-3 mcg per serving
- Pork – moderate amounts
Chuck steak and lean cuts have the most B12.
Poultry and Chicken
Chicken and turkey have B12, but not as much as red meat or fish.
Poultry B12 content:
- Chicken breast – about 0.3 mcg per serving
- Turkey – similar to chicken
- Duck – higher than chicken
You’d need to eat more chicken to get the same B12 as beef or fish.
Dairy Products
Research has found that your body absorbs the vitamin B12 in milk and dairy products better than the vitamin B12 in beef, fish, or eggs. That’s good news!
Dairy sources:
- Milk (1 cup) – 1-1.5 mcg
- Swiss cheese (1 slice) – 0.95 mcg
- Yogurt (1 cup) – 0.75-1.3 mcg
- Cottage cheese – 0.5 mcg per serving
- Feta cheese – 0.5 mcg per ounce
Dairy is great if you eat it every day. The amounts add up.
Eggs: Easy B12 Source
Two large eggs supply about 46% of the daily value for vitamin B12. Plus, egg yolks have higher levels of vitamin B12 than egg whites, and the B12 in egg yolks is easier to absorb.
Always eat the whole egg. The white part barely has any B12.
Check out how to take methylated B12 for maximum absorption to get the most from your food.
Limited Plant Sources of Methylated B12
Vitamin B12 is well-known to be the sole vitamin that is absent from plant-derived food sources. But there are a few plant foods with small amounts.
Nori and Purple Laver
Dried purple laver contains approximately 32.3 mcg per 100 grams dry weight. That’s pretty good for a plant!
Nori sheets (used in sushi) have B12. But you’d need to eat many sheets to get enough.
Nutritional Yeast
Many nutritional yeast brands are fortified. The natural kind has very little B12. Most nutritional yeasts are fortified with synthetic B12, so check the label.
Fortified Foods
These foods have B12 added to them:
- Fortified cereals
- Fortified plant milk (soy, almond, oat)
- Fortified meat substitutes
- Some energy drinks
The added B12 is usually cyanocobalamin, not methylcobalamin. It still works, but it’s not the natural form.
If you’re vegan and need methylated B12, supplements are your best bet.
How Much Methylated B12 Do You Need?
Most people 14 and older need about 2.4 micrograms of vitamin B12 a day.
Daily needs by group:
- Adults – 2.4 mcg
- Pregnant women – 2.6 mcg
- Nursing mothers – 2.8 mcg
- Kids 1-13 years – 0.9 to 1.8 mcg
- Babies under 1 year – 0.4-0.5 mcg
Your liver stores extra B12. So if you eat liver once, you’re set for a while.

Most cooking methods keep B12 pretty well. But gentler cooking is better.
Methylated B12 vs Regular B12 Supplements
When cyanocobalamin enters your body, it’s converted into either methylcobalamin or adenosylcobalamin, which are the two active forms of vitamin B12 in humans.
But why make your body do extra work? Methylated B12 is better than regular B12 because it’s ready to use.
When Food Isn’t Enough
Sometimes you need supplements too:
- If you don’t eat animal products
- When you’re older
- If you have absorption problems
- During pregnancy or nursing
Our methylated B12 supplements give you the natural form your body loves.
Benefits of Getting Enough Methylated B12
When you get enough B12 from food, good things happen.
Energy and Less Fatigue
Feeling fatigued is one of the first signs of identifying a B12 deficiency. Get enough B12, and your energy comes back.
Methylated B12 helps with fatigue by helping your cells make energy.
Better Brain Function
Your brain needs B12 to work right. Methylcobalamin contributes to the maintenance of the nervous system, assisting in the development and protection of the myelin sheath.
This means:
- Clearer thinking
- Better memory
- Improved mood
- Less brain fog

- Nuts
- Fatty fish (which already have B12!)
Special Considerations for Different Diets
Different eating styles need different approaches.
For Meat Eaters
You probably get enough B12 if you eat:
- Fish twice a week
- Meat a few times a week
- Eggs or dairy daily
Easy! Just eat a variety of animal foods.
For Vegetarians
You can get B12 from:
- Eggs
- Milk and cheese
- Yogurt
- Fortified foods
Eat these foods every day to get enough.
For Vegans
The average daily intake of vitamin B12 is about 7.2 micrograms in people who eat meat, but only 0.4 micrograms in vegans.
Vegans should:
- Take B12 supplements
- Eat fortified foods daily
- Consider nutritional yeast
- Check B12 levels regularly

Common Questions About B12 in Foods
Does Cooking Destroy B12?
B12 is pretty stable. Most cooking keeps most of the B12. But very high heat for long times can reduce it a bit.
Can You Get Too Much B12 From Food?
Excess vitamin B12 is stored in your liver. Your body saves what it doesn’t need. Getting too much from food is very rare.
Check the side effects of methylated B12 to know what to watch for.
What About B12 Injections?
Some people need shots because their body can’t absorb B12 from food. This includes people with:
- Pernicious anemia
