La Vitamin B12 it is a water-soluble vitamin present in various foods of animal origin and with various fundamental functions for our organism, such as helping to produce red blood cells or caring for the functioning of the central nervous system. A vitamin B12 deficiency can cause several symptoms, some of which are striking handspiedi e legs. (From cracked heel to swelling, what do your feet say about your health?)





Vitamin B12 Deficiency Symptoms

An adult should take on average 2,4 g of vitamin B12 per day. However, like most vitamins, B12 is not produced by our body so we have to get it from foods or supplements (especially if you follow a vegan diet). However, vitamin B12 deficiency is extremely common as many do not get the necessary amounts of the vitamin to meet their needs and for the body to function properly.

According to Harvard Medical School, vitamin B12 deficiency can be "subtle" and "harmful," so warning signs need to be identified early. The deficiency can then develop slowly, which causes symptoms to appear more gradually. One of these symptoms is a sensation of tingling in the hands, feet or legsThis is because a lack of vitamin B12 will lead to abnormal development of red blood cells and, as less oxygen is able to reach the extremities of the body, such as hands or feet, a tingling sensation can occur. There feeling numb in various parts of the body it also occurs due to the role of the vitamin in the nervous system, ie when there is no proper blood supply to the nerves of our body.

Other signs of B12 deficiency are:

  • loss of color in the skin,
  • swollen and inflamed tongue,
  • difficulty walking,
  • reduction of cognitive abilities,
  • memory leaks,
  • worsening of vision,
  • irritability and depression.

It is recommended that you visit your doctor if you think you have any of these symptoms. Vitamin B12 deficiency can be easily detected with a blood test and can be countered with the right dosage of supplements.
