Foods with the highest concentrations of vitamin B12, often referred to as "super" B12 foods, are primarily animal products and fortified foods. Shellfish, organ meats, and fatty fish are among the most potent sources.
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.
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.
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.
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.
The worst symptoms of B12 deficiency involve severe neurological damage, including severe memory loss, confusion, dementia, psychosis, hallucinations, balance problems, trouble walking, and irreversible nerve damage (neuropathy), alongside serious mental health issues like severe depression or irritability, with physical signs including extreme fatigue, pale skin, and a sore, smooth tongue. These severe cognitive and neurological issues are the most concerning because they can become permanent if left untreated.
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.
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.
Symptoms of vitamin B12 or folate deficiency anaemia
Milk. One of the best drinks with B12 is milk. One cup of whole milk contains approximately 1.32µg of vitamin 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].
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.
Consider beef, liver, sardines, salmon, eggs, milk, cheese, clams and tuna. If you don't eat animal products, you may have a more challenging time getting enough vitamin B12. Look for foods fortified in B12, such as some breakfast cereals, soy products and plant milk.
Avocados: Healthy Fats for Absorption
Technically a fruit, avocados provide healthy monounsaturated fats and folate. These healthy fats can improve the absorption of fat-soluble vitamins, and folate works closely with B12 in many bodily functions, including DNA synthesis and red blood cell production.
Causes of vitamin B12 deficiency
Symptoms such as pins and needles, disturbed vision, a sore and red tongue, mouth ulcers, muscle weakness and problems with balancing and walking, psychological problems such as depression and confusion, problems with memory, understanding and judgement could also be related to B12 deficiency.
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.
The best form of B12 is often considered methylcobalamin, as it's a naturally occurring, active form the body uses immediately, though adenosylcobalamin is also an active form, with a combination often recommended for better results, especially for deficiency or absorption issues, while cyanocobalamin, a cheaper synthetic option, is effective but requires conversion and is less ideal for some. For general supplementation, natural forms like methylcobalamin or adenosylcobalamin are preferred for better retention.
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.
The Boots Vitamin B12 Blood Test Kit checks your vitamin B12 levels, using a finger-prick blood sample. Use of this kit requires internet access. All personal data in relation to this product, services and online platforms are collected and processed by MyHealthChecked.
Nail changes in vitamin B12 deficiency present as hyperpigmentation of nails like bluish discoloration of nails, blue-black pigmentation with dark longitudinal streaks, and longitudinal and reticulate darkened streaks.
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.
Disturbed or blurred vision can also occur as a result of a Vitamin B12 deficiency. This happens when the deficiency causes damage to the optic nerve that leads to your eyes. The nervous signal that travels from the eye to the brain is disturbed due to this damage, leading to impaired vision.
The most common causes of imbalance without dizziness are related to dysfunction of the muscles, joints and peripheral nerves (proprioceptive system), or the central nervous system (brain).
