5. Tingling and Numbness
One of the more long-term effects of vitamin B deficiency is the sensation of numbness and tingling. This is usually described to be similar to the feeling of an electric current rushing from head to toe. For others, it is the numbing feeling of ‘pins and needles’ in their hands and feet. These strange sensations are a result of nerve damage and can be painful when left untreated for too long.
This nerve damage is usually triggered by low oxygen levels, which can prevent your nerves from functioning properly. Vitamin B is an important contributor to your metabolic pathway. Your metabolic pathway is responsible for producing myelin, which acts as protection and insulation around your nerves.
Without vitamin B, myelin won’t produce properly, which explains why you are probably feeling those prickling sensations. These neurological symptoms are usually associated with anemia, which can occur due to vitamin B deficiency.
