Yes, boiled eggs are a good source of vitamin B12 (cobalamin), with most of the nutrient concentrated in the yolk, supporting nerve function and red blood cell formation, making them a highly nutritious snack alongside other B vitamins, D, and quality protein. A single large boiled egg provides a significant portion of your daily B12 requirement, around 23%.
Each egg contains about 6 grams of protein, making them a fantastic source for meeting daily protein requirements. Eggs are also rich in essential nutrients such as vitamin B12, which supports nerve function and red blood cell formation, and vitamin D, which helps in the absorption of calcium for bone health.
To quickly increase B12, focus on animal products (meat, fish, dairy, eggs) and fortified foods (cereals, plant milks, nutritional yeast), but for a significant deficiency or rapid boost, especially if dietary changes aren't enough, consult a doctor for high-dose supplements or B12 injections, as severe cases require medical intervention for proper absorption and treatment, note NHS and Healthline.
If you eat eggs, they can be a good source of vitamin B12. One hard-boiled egg has about 0.6 micrograms of vitamin B12. That's 25% of how much you should get per day. Of course, you'll need to eat the whole egg to get the vitamin B12, as most of it comes from the yolk.
The foods highest in Vitamin B12 are animal products, with clams and liver (beef, lamb) being exceptionally rich sources, often providing several hundred percent of the daily value in a single serving, alongside seafood like mussels, sardines, and salmon, dairy, eggs, and fortified cereals and nutritional yeast for vegans.
B12 deficiency can trigger specific food cravings, most notably for meat, fish, or eggs, as the body seeks animal-based sources to replenish the vitamin, especially in those on vegetarian/vegan diets or older adults. While cravings for sugary or salty foods can also signal general B-vitamin issues, the distinct urge for protein-rich animal products is a key indicator, but professional testing is crucial for confirmation.
If you eat meat, fish or dairy foods, you should be able to get enough vitamin B12 from your diet. But as vitamin B12 is not found naturally in foods such as fruit, vegetables and grains, vegans may not get enough of it.
