The Effects of Vitamin B12 Deficiency

Cobalamin, more commonly known as vitamin B12, is a member of the family of B-complex vitamins. It is required for the function of nerve cells, DNA production, and blood cell production. It is also an essential nutrient that keeps your metabolism in check. Vitamin B12 can be found naturally in meals, poultry, seafood, eggs, and dairy products (foods that are typically high in protein). It is offered over the counter as a supplement, and weekly injections are available at our Jacksonville wellness center. Vitamin B12 deficiency strikes 48 million Americans, or 16% of the population.

The deficiency of Vitamin B12 strikes all ages, races, and both sexes. It is arguably the most common nutritional deficiency causing health issues in the United States, as witnessed at our Jacksonville wellness center. Early diagnoses and treatment is critical to prevent neurological injury, disability, and even premature death. The following are only some of the more common effects of vitamin B12 deficiency.

Pernicious Anemia

Because vitamin B12 plays a principal role in numerous body functions, it’s unsurprising that a deficiency leads to a number of alarming conditions. Pernicious anemia is a type of anemia characterized by large, dysfunctional red blood cells, and develops when the body does not have enough vitamin B12. Symptoms of pernicious anemia include fatigue, lack of energy, lightheadedness, and headaches.

Dementia is a disease characterized most commonly by memory loss and changes in behavior. Vitamin B12 deficiency is one of the more recently recognized causes. Research suggests that the dementia associated with vitamin B12 deficiency may be a result of elevated homocysteine levels.

Peripheral Neuropathy

Vitamin B12 is a co-factor in the formation of myelin, which is a protective covering of the peripheral nerves. A deficiency of myelin interferes with normal function of the peripheral nerves, which control movement and sensation of the body. Symptoms of peripheral neuropathy include tingling, numbness and weakness.


Vitamin B12 deficiency is one of the known causes of stroke among young people who are not otherwise at risk of one. The resulting increase in plasma homocysteine levels is a risk factor for stroke, as it causes an increase of plaque on the carotid artery.

In addition to providing a multitude of health benefits, vitamin B12 is also known for its fat-burning properties when delivered as Lipotropic B12 injections. Schedule a consultation at our Jacksonville wellness center to learn how this miracle vitamin can help you.
