A deficiency in B12 most often occurs through not consuming enough B12 in your diet, but may also be the result of gastrointestinal problems. A diet that includes a balance of meat, fish and dairy products typically contains enough vitamin B12 to support your body’s requirements.
If you don’t consume enough vitamin B12 through your diet or take vitamins with B12 daily, then you may become deficient over time. Symptoms of low vitamin B12 include mouth ulcers and a sore, red tongue, extreme tiredness and fatigue, breathlessness, headaches, palpitations and pale skin.
Vitamin B12 is known for its key role in the production of red blood cells, which carry oxygen throughout the body. Vitamin B12 also supports the nervous system by contributing to the formation of the protective covering around nerves, and it is also involved in DNA synthesis, aiding in the proper development and maintenance of genetic material.
Good food sources of vitamin B12 include lean meats such as beef and poultry, omega-3-rich fish like salmon, and shellfish like clams and oysters. Dairy products including milk, cheese, and yoghurt are also rich sources of this essential vitamin, as are B12-fortified cereals, plant-based milk, and nutritional yeast.
Fatigue, and a general sense of tiredness are common early indicators of low vitamin B12. This vitamin plays a crucial role in red blood cell production, so symptoms similar to those of anaemia, including shortness of breath and pale skin may present. Low B12 can also lead to nerve-related symptoms including numbness or tingling in the hands and feet. If you susupect you have low vitamin B12, it is recommended to see your GP for further investigation.
Low levels of vitamin B12 can contribute to fatigue and a feeling of tiredness. Vitamin B12 plays a crucial role in the production of red blood cells, which carry oxygen around the body. When vitamin B12 levels are low, the body may not produce enough red blood cells, which can lead to anaemia and result in fatigue, weakness, and a lack of energy.
