About one cup (250ml) of milk provides over 50% of your daily Vitamin B12 needs (around 1.3 mcg), making two cups a good daily target for non-vegans to meet requirements (around 2.4 mcg/day). Dairy is a reliable source, but vegans need fortified plant milks, which can also offer significant B12 per cup.
Yes. A liter a whole milk provides 4.5 mcg vitamin B12, which is well above the RDA of 2.4 mcg. And reduced fat and fat free milk have even higher levels of B12.
Yes, Vitamin B12 can help with vertigo, especially if a deficiency is the underlying cause, as low B12 levels can lead to neurological problems, anemia, poor nerve function, and reduced blood flow to the brain, all contributing to dizziness and imbalance, with supplementation showing promise in improving symptoms.
For pregnancy, Vitamin B12 (like cyanocobalamin or hydroxocobalamin) is crucial for fetal brain/nerve development, especially for vegans/vegetarians; most get enough from animal products, but supplements (oral or injections for deficiency) are recommended if dietary intake is low, with doctors advising specific forms and dosages to prevent anemia and neural tube defects, so always consult your healthcare provider.
During pregnancy, ensuring adequate vitamin B12 levels is crucial for fetal development and maternal health. The third trimester is especially significant as the fetus undergoes rapid growth and development, necessitating adequate nutrient transfer from the mother.
Good sources of vitamin B12 include:
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 have vitamin B12–deficiency anemia, you may have the typical symptoms of anemia at first, such as fatigue, paleness, shortness of breath, headaches, or dizziness. If left untreated, you may start to notice brain and nervous system symptoms.
Warning signs of vitamin B12 deficiency include extreme fatigue, weakness, pale/yellow skin, numbness/tingling (pins and needles), cognitive issues (memory fog, confusion), mood changes (depression/irritability), and a sore, red tongue, alongside potential shortness of breath, heart palpitations, and balance problems, as symptoms develop slowly and can worsen over time. It's crucial to see a GP, as early treatment prevents potentially irreversible neurological damage, say NHS, Cleveland Clinic, and WebMD.
One cup of 2% milk contains 1.3 mcg of vitamin B12, 54% of the daily value, per the NIH.
According to the USDA, one cup of soya milk provides 45% of recommended Vitamin B12 intake. Another popular dairy product, yogurt is also known to load you up with a good amount of vitamin B12.

milk. cheese. eggs. some fortified breakfast cereals.
People need vitamin B-12 for the brain to work well. If not treated, vitamin B-12 deficiency can lead to issues with the nerves, brain or spinal cord. These might include lasting tingling in the hands and feet or trouble with balance.
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].
Cutaneous manifestations associated with vitamin B12 deficiency are skin hyperpigmentation, vitiligo, angular stomatitis, and hair changes. A diagnosis of vitamin B12 deficiency is often overlooked in its early stages because these signs are not specific to vitamin B12 deficiency alone.
Our study successfully supplemented vitamin D deficiency through vitamin D monotherapy. This significantly reduced the recurrence rate of vertigo. Furthermore, in our study, neither the vitamin D group nor the placebo group reported any adverse effects.
People with very low vitamin B-12 levels can have symptoms such as fatigue, muscle weakness, stomach problems, nerve damage, vision problems and mood changes. They also may have low iron, called anemia, or low blood counts. The recommended daily amount of vitamin B-12 for adults is 2.4 micrograms (mcg).
Foods or drinks to avoid
Organ meats and shellfish are the richest dietary sources, with a 3-ounce (85 g) serving of cooked clams providing approximately 84.1 µg, while beef liver contains about 70.7 µg. Fatty fish, such as trout and salmon, supply 5.4 µg and 4.8 µg per 3-ounce serving, respectively.
Vitamin B12 deficiency can also cause symptoms that affect your brain and nervous system (neurological symptoms), including: numbness. muscle weakness. psychological problems, which can range from mild depression or anxiety, to confusion and dementia.
Foods that contain the most biotin include organ meats, eggs, fish, meat, seeds, nuts, and certain vegetables (such as sweet potatoes) [2,12].
If you're pregnant, not having enough vitamin B12 can increase the risk of your baby developing a serious birth defect known as a neural tube defect.
Vitamin B12 deficiency anaemia is usually treated with injections of vitamin B12, called hydroxocobalamin. At first, you'll have these injections every other day for 2 weeks or until your symptoms have started improving. Your GP or nurse will give the injections.
