Vitamin B12 deficiency significantly affects the mouth by causing a sore, red, smooth tongue (glossitis), frequent mouth ulcers, cracked corners of the mouth (angular cheilitis), burning sensations, and altered taste, due to its role in cell repair, red blood cell production, and nerve health, leading to pale gums, inflammation, and impaired tissue healing.
Vitamin B12 plays a crucial role in oral health, and its deficiency can lead to a spectrum of oral manifestations. These include glossitis, glossodynia, recurrent ulcers, cheilitis, dysgeusia, lingual paresthesia, burning sensations, and pruritus [1,2].
No significant interactions are reported between amlodipine and Vitamin B12 specifically, but multivitamins with minerals might decrease amlodipine's effectiveness, so always tell your doctor about all supplements, including B12, as they can affect your blood pressure and medication response. While B12 itself seems safe, other supplements like St. John's Wort can interact, and potential B vitamin effects on blood pressure meds aren't fully understood, making professional advice crucial.
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.
When your diet lacks essential vitamins and minerals, symptoms such as bleeding gums, mouth sores, and tooth decay may appear. Since oral cells regenerate quickly, deficiencies often manifest early in the mouth before other body systems show signs.
One key sign of vitamin B12 deficiency is the atrophy of lingual papillae on the tongue. This condition causes the small projections on the tongue's surface to disappear, making it look smooth. The lingual papillae are important for the tongue's texture. They help with food manipulation and taste.
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.
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.
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.
B12 (Cobalamin)
What it does: B12 is necessary for cell reproduction and can be applied topically for skin benefits because it reduces inflammation, dryness, and acne. It is sometimes used to treat conditions like psoriasis and eczema.
Possible interactions include:
Common side effects
Key points about vitamin B12 deficiency anemia
Without enough red blood cells, your tissues and organs don't get enough oxygen. Without enough oxygen, your body can't work as well. Symptoms include weak muscles, numbness, trouble walking, nausea, weight loss, irritability, fatigue, and increased heart rate.
Symptoms of vitamin B12 deficiency
a pale yellow tinge to your skin. a sore and red tongue (glossitis) mouth ulcers. pins and needles (paraesthesia)
Cavities that develop quickly and unexpectedly may be the result of: Sudden Dietary Changes: You might have changed your diet in some way, including drinking more soda, adding more sugar to your coffee, eating more starchy or acidic foods, or consuming more sweets.
Phosphorus – Calcium's Silent Partner
Phosphorus works hand-in-hand with calcium to strengthen teeth and bones. It helps your body absorb calcium more efficiently and plays a vital role in enamel rebuilding and repair.
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.
Not diet-related
If your vitamin B12 deficiency is not caused by a lack of vitamin B12 in your diet, you'll usually need to have an injection of hydroxocobalamin every 2 to 3 months for the rest of your life.
It is also known as cobalamin. Vitamin B12 is vital for: making new blood cells.
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.
If unable to self-administer: oral cyanocobalamin 50micrograms one tablet daily (taken between meals). If symptoms do not improve after 3 months, increase dose every 3 months in 50microgram steps up to 150microgram daily, or change to IM hydroxocobalamin 1mg every 3 months (administered in clinic).
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.
Foods or drinks to avoid
It may take a few weeks before your vitamin B12 levels and symptoms (such as extreme tiredness or lack of energy) start to improve. If you have hydroxocobalamin injections to boost your vitamin B12 levels at the start of treatment, the cyanocobalamin tablets may start to work within a few days.
