Is 2 eggs a day enough B12?
Asked by: Marina Weber | Last update: June 21, 2026Score: 4.6/5 (32 votes)
Two eggs a day provide roughly 46%–50% of the recommended daily value (DV) of Vitamin B12, making them a significant contributor but not a complete daily source, as they contain about 0.6 mcg of B12 per egg against a 2.4 mcg recommendation. While they are highly nutritious, relying solely on two eggs may not meet the full daily need for most adults.
How many eggs per day to increase B12?
A single large egg contains approximately 0.6 micrograms of vitamin B12, with the majority concentrated in the yolk. Two large eggs provide about 1.2 micrograms, contributing meaningfully to the UK adult daily requirement of 1.5 micrograms.
What is the #1 food highest in B12?
Top foods with B12
Clams, 3 ounces: 84 mcg. 100% fortified breakfast cereal (check the label), 1 serving: 6. Trout, 3 ounces: 5.4. Salmon, 3 ounces: 4.9.
Can MTHFR cause B12 deficiency?
Yes, MTHFR gene mutations (specifically the C677T variant) are strongly associated with an increased risk of vitamin B12 deficiency. While MTHFR primarily affects folate metabolism, it also impacts B12 utilization. Those with homozygous MTHFR mutations have a 4.2 times higher probability of having a B12 deficiency.
What do you crave when your B12 is low?
When Vitamin B12 is low, you often crave animal-based products like red meat (beef, lamb), fish, and eggs. These cravings arise because the body seeks nutrient-dense foods to correct the deficiency, resulting in sudden, intense hunger for protein-heavy meals. Some individuals may also crave sugar due to fatigue.

Do you feel hungry when your B12 is low?
Decreased appetite and weight loss. As a result of digestive problems, such as nausea, people with vitamin B12 deficiency may lose their appetite. A decreased appetite can lead to weight loss in the long term.
What drink has a lot of B12?
Drinks high in vitamin B12 include dairy milk, fortified plant-based milks (soy, almond, rice), kefir, energy drinks, and specific nutritional powders like AG1. One cup of dairy milk provides approximately 46% of the daily value (DV), while fortified soy milk can provide up to 124% DV depending on the brand.
Why are doctors stopping B12 injections?
Coronavirus has made it necessary to move patients on B12 injections to oral treatment. Reason: RISK REDUCTION in terms of limiting your movement outside your home and contact with our staff and nurses. Nationally all NHS organisations will be stopping injections during this difficult time.
What are the worst symptoms of B12 deficiency?
The worst symptoms of severe or long-term Vitamin B12 deficiency stem from irreversible neurological damage and profound anemia, including severe cognitive impairment (dementia/memory loss), debilitating ataxia (difficulty walking/balance), peripheral neuropathy (numbness/pain in hands and feet), psychosis, vision loss, and extreme fatigue.
Can low B12 raise A1C?
Yes, a low vitamin B12 level can cause a falsely high HbA1c, as the deficiency leads to megaloblastic anemia, which increases red blood cell survival time and alters A1c measurements. This phenomenon may cause a misclassification of glycemic status, making it appear that average blood sugar is higher than it actually is.
What yogurt is high in B12?
Plain Greek yogurt is one of the best dairy sources of vitamin B12, often providing around 45% of the daily value (DV) in a 6-7 oz serving. Nonfat and low-fat Greek yogurts (such as FAGE Total or Chobani) are exceptionally high in B12, aiding in nerve function and energy production.
How to get 100% of B12?
Vitamin B12 is present in foods of animal origin, including fish, meat, poultry, eggs, and dairy products [5,12]. Plant foods do not naturally contain vitamin B12. However, fortified breakfast cereals and fortified nutritional yeasts are readily available sources of vitamin B12 that have high bioavailability [13,14].
Is cheese a good source of B12?
Yes, cheese is a good, natural source of vitamin B12 for lacto-vegetarians and those who consume dairy, with higher concentrations often found in sheep and Swiss cheeses. A single slice of Swiss cheese can provide roughly 0.9 mcg (about 38% of the daily value) of B12.
Can I get all my B12 from eggs?
Yes, eggs are a good source of vitamin B12cap B sub 12𝐵12, but they likely do not provide enough on their own to meet the full daily requirement for most adults, providing about 20–25% (0.5–0.6 mcg) of the daily value per large egg. While they contribute to, and are a key part of, a healthy diet, they are not considered a "high-dose" source compared to fish or meat.
How much B12 do seniors need daily?
Seniors over age 50 should consume 2.4 micrograms (μgmu g𝝁𝒈) of Vitamin B12 daily, although many experts recommend higher supplementation doses (often 25–100 μgmu g𝝁𝒈 or more) due to reduced absorption. Because up to 30% of older adults cannot properly absorb natural B12 from food, reliance on fortified foods or supplements is strongly advised.
How many eggs to eat per day for vitamin B12?
Eating two large eggs per day provides roughly 46% of the Recommended Daily Value (DV) of Vitamin B12, making them a significant dietary source. A single large egg contains about 0.6 mcg of B12, concentrated in the yolk. While helpful, eggs should be part of a varied diet to meet the daily 2.4 mcg goal.
What are the two main causes of B12 deficiency?
Causes of Vitamin B12 deficiency
- Malabsorption due to gastrectomy, gastric resection, crohn's disease, chronic alcoholism, coeliac disease, pancreatic failure and/or chronic alcoholism.
- Nutritional such as inadequate dietary intake of vitamin B12 (e.g., strict vegan diet) and malnutrition.
What does it feel like to be low in B12?
Vitamin B12 deficiency commonly feels like profound fatigue, weakness, and "pins and needles" (numbness or tingling) in hands and feet. It often develops gradually, causing symptoms like brain fog, memory loss, dizziness, and a sore, smooth tongue. Other symptoms include pale skin, palpitations, irritability, and, if severe, balance issues.
How much B12 is in 2 eggs?
Two large eggs provide approximately 1.1 to 1.2 micrograms (μgmu g𝝁𝒈) of Vitamin B12. This amount satisfies nearly 50% of the daily recommended intake for an adult. The B12 is concentrated in the yolk, making whole eggs a strong source for this nutrient.
Do you stay on B12 injections for life?
It's OK to have hydroxocobalamin injections for a long time. Some people will need to have them for the rest of their lives.
What are signs you need a B12 shot?
You may need B12 injections if blood tests confirm a deficiency, or if you experience symptoms like extreme fatigue, brain fog, numbness/tingling in hands/feet, or mood changes, particularly if you have absorption issues. Injections are usually necessary for those with pernicious anemia, Crohn’s disease, or those who have had gastric bypass surgery.
Can low B12 be life threatening?
Yes, very low vitamin B12 levels are extremely dangerous and can lead to permanent damage if left untreated. Severe deficiency causes irreversible neurological damage, severe anemia, and potentially heart failure. Early diagnosis is critical to avoid irreversible neurological complications.
Why do I feel so good after taking B12?
You likely feel better after taking Vitamin B12 because it rapidly addresses a deficiency that was causing fatigue, brain fog, and low mood. B12 is essential for producing red blood cells to deliver oxygen to muscles, supporting nervous system health (myelin sheath), and boosting metabolism, which directly increases energy and mental clarity.
What juice is high in B12?
Vitamin B12-rich juices are typically fortified, as the vitamin is primarily found in animal products. Best options include fortified orange juice, beetroot juice with added B12, and plant-based milks (soy or almond) fortified with the nutrient. These help boost energy, nerve function, and red blood cell formation.
What is the best form of B12 to take?
Methylcobalamin is generally considered the best form of vitamin B12 for daily supplementation due to its high bioavailability and active status. For maximum absorption, sublingual tablets or liquids that dissolve under the tongue are superior to capsules, particularly for those with absorption issues.
