Vitamin B12 is a crucial nutrient that is naturally found almost exclusively in animal foods. Also known as cobalamin, B12 is essential for DNA production, red blood cell formation, neurological function, and more. This makes it especially important for vegans and vegetarians to ensure adequate intake of fortified foods or supplements. This article will highlight vitamin B12 foods sources from the sample menu provided, along with general tips for getting enough from a plant-based diet.
Animal Foods High in B12
The menu provided includes various animal-based options that can provide a significant amount of B12:
- Salmon – A 3oz salmon fillet contains over 300% DV B12. Choose grilled salmon from the à la carte options or teriyaki salmon for dinner.
- Shrimp – A 3oz serving of shrimp provides about 150% DV B12. The menu includes Cajun shrimp, Baja shrimp tacos, and à la carte shrimp choices.
- Eggs – One large egg contains about 5mcg or over 200% DV B12. The menu features eggs in dishes like veggie omelets, frittatas, scrambles, and egg salad.
- Turkey – A 3oz turkey burger or 2 slices of turkey deli meat provides about 40% DV B12. Turkey sausage and ground turkey also contain B12.
- Chicken – A 3oz grilled chicken breast has about 6% DV B12. The menu includes chicken entrees, salads, sandwiches, bowls, and light bites.
- Cheese – 1oz cheddar or Swiss cheese contains about 20% DV B12. Add cheese to eggs, sandwiches, or bowls.
As you can see, even smaller servings of salmon, shrimp, eggs, poultry, and cheese supply a substantial dose of B12. Omnivores who eat varying amounts of animal foods can easily meet their B12 needs through this diet.
Plant-Based B12 Sources
For vegetarians and especially vegans, getting B12 through fortified foods or supplements is essential, as plant foods do not naturally contain this vitamin. Here are some vegan-friendly options from the menu for increasing B12 intake:
- Fortified non-dairy milk – 1 cup of fortified almond, soy, oat, or other milk can have up to 90% DV B12. Use in smoothies, cereal, or recipes.
- Nutritional yeast – 2 tbsp of fortified nutritional yeast may provide over 100% DV B12. Sprinkle on pasta, roasted veggies, popcorn or salads.
- Fortified breakfast cereal with non-dairy milk – 3/4 cup of cereal and milk can supply 50% to 100% DV B12 depending on the brand.
- Fortified meat alternatives – Some vegan burgers, sausages, and deli slices are fortified with B12. Check labels.
- Fortified snack bars – Granola, protein, and energy bars often contain added B12. Have one for an on-the-go snack.
Though amounts can vary based on brand and product, fortified foods can provide vegans with a dietary source of B12. Supplements are still recommended for optimal intake.
B12 Supplements for Vegans
To complement dietary sources, vegans should consider a daily B12 supplement of at least 25-100mcg. Convenient supplement forms include:
- B12 tablets or capsules
- Sublingual B12 liquid drops
- Multivitamin containing B12
- B12 gummies
A daily supplement, in addition to fortified foods, helps provide adequate B12 intake for those eating 100% plant-based. As B12 is water soluble, there is very little risk for toxicity. Ask your healthcare provider about the right B12 supplement and dosage for you.
Signs of B12 Deficiency
Since B12 plays diverse roles in the body, deficiency can cause varied symptoms that develop over weeks or months. These may include:
- Chronic fatigue or weakness
- Numbness or tingling
- Poor memory and concentration
- Neurological changes
- Depression or mood disorders
- Pale skin, sores in mouth
- Poor appetite
Left untreated, B12 deficiency can potentially lead to permanent neurological damage. Vegans, as well as older adults and those with digestive conditions, are most at risk. Having blood levels tested annually can detect low B12 before symptoms occur.
Achieving Adequate B12 Intake
The menu provided offers diverse options for getting vitamin B12 from a balanced diet:
- Omnivores – Consume 2-6 mcg daily by including fish, poultry, eggs, dairy and cheese.
- Vegetarians – Get 3-4 mcg daily through eggs, dairy products, and fortified foods.
- Vegans – Aim for 2.4-5 mcg from fortified sources plus a 25-100 mcg supplement.
Be aware of deficiency symptoms and get levels checked if concerned. With the right diet and supplementation, all dietary preferences can obtain the B12 necessary for good health.
