7 signs of vitamin B12 deficiency

Vitamin B12 is not produced in our body. It only comes from external sources. It is an essential nutrient used to produce red blood cells, DNA, and nerves.

Unlike most vitamins, B12 is found in minimal amounts in plants. For this reason, vegans and vegetarians are highly prone to vitamin B12 deficiency. Microorganisms such as bacteria and fungi can produce vitamin B12. Because bacteria can be found in the soil, nutrients may contain small amounts of this vitamin. Foods that contain small amounts of vitamin B12 include mushrooms and fermented foods such as tempeh, a soy product.

Vegetarians who consume enough dairy products can get B12 from eggs, milk and yogurt. If you’re avoiding meat, eggs, and dairy products, you may want to consider taking a vitamin B12 supplement. Pregnant and breastfeeding women have a higher daily requirement of vitamin B12 and it is best to consult a specialist to determine the correct amount.


The foods you consume should provide you with enough vitamin B12 to avoid health problems, but if you are concerned, you can consult your doctor for blood tests that will show your B12 level.

We don’t need a lot of vitamin B12. Most adults only need 2.4 micrograms a day, but it is essential for many bodily functions and a deficiency can cause serious health problems.

Some foods add vitamin B12 to boost their health benefits, but foods that naturally contain large amounts of vitamin B12 include dairy products, eggs, fish, chicken, turkey, red meat, and shellfish. Vitamin B12 especially helps fight cancer, heart disease and dementia.


The 7 main symptoms of vitamin B12 deficiency in general are:


Are you constantly tired? Vitamin B12 is essential for building energy in the body. When this vitamin is not enough, the body cannot get enough oxygen and energy. Dizziness is also a sign that you’re not getting enough vitamin B12.

Tingling and Numbness

Loss of sensation in the hands and feet, accompanied by a tingling sensation like pins and needles, can signify vitamin B12 deficiency. Blood tests must be done to determine the cause.

Joint pain

Severe joint pain that is not the result of a chronic disease such as arthritis can be a warning sign. Slowing of reflexes is one of the symptoms in patients with vitamin B12 deficiency.

Rapid Heartbeat or Breathing

Rapid breathing and rapid heartbeat may also be associated with vitamin B12 deficiency. If any of these bother you, be sure to see a doctor.


With severe vitamin B12 deficiency, symptoms such as complete weakness making walking difficult may occur. In addition to muscle weakness, problems with balance and stumbling can also indicate a problem.


Yellowing of the skin and whites of the eyes is a typical sign of jaundice, indicating some severe health problems. Among the causes of jaundice is a deficiency of vitamin B12.

Tongue Swelling

Some patients with vitamin B12 deficiency may also experience tongue inflammation. Other symptoms associated with the oral cavity include a flat tongue and decreased sense of taste.
