10 Signs That You May Have a Vitamin B12 Deficiency

Vitamin B12 is important for many aspects of health.

Vitamin B12, also known as cobalamin, is an essential nutrient that plays a crucial role in various bodily functions. It is involved in the formation of red blood cells, nerve function, DNA synthesis, and the metabolism of proteins and fats. Since our bodies cannot produce vitamin B12, we rely on dietary sources or supplements to meet our daily requirements. Deficiency in this vital nutrient can lead to a range of health issues.

10 Common Signs and Symptoms of Vitamin B12 Deficiency

    1. Fatigue and weakness: Feeling unusually tired or weak is one of the most common early signs of a B12 deficiency. This fatigue may be accompanied by a lack of energy.

    2. Anemia: A B12 deficiency can lead to a type of anemia called megaloblastic anemia, which can cause symptoms such as pale skin, shortness of breath, and dizziness.

    3. Numbness and tingling: Numbness, tingling, or a "pins and needles" sensation, especially in the hands and feet, is a common neurological symptom of B12 deficiency.

    4. Difficulty walking or balance problems: Some people with severe B12 deficiency may experience difficulty walking, balance issues, or a sensation of unsteadiness.

    5. Cognitive and mood changes: B12 deficiency can affect your brain function, leading to memory problems, mood disturbances (such as depression or irritability), and difficulty concentrating.

    6. Glossitis: Inflammation of the tongue (glossitis) can occur, leading to a sore, red, and swollen tongue.

    7. Mouth ulcers: B12 deficiency can sometimes cause painful mouth ulcers or sores in the corners of the mouth.

    8. Vision problems: Although less common, some people may experience vision changes or optic nerve damage due to a severe B12 deficiency.

    9. Heart palpitations: Irregular heartbeat or palpitations can be associated with a severe deficiency.

    10. Digestive issues: B12 deficiency can be caused by conditions that affect the absorption of the vitamin in the digestive system, such as pernicious anemia or gastrointestinal disorders. Symptoms may include diarrhea, constipation, or other digestive problems.

    It is important to remember that these symptoms can be caused by various other medical conditions as well, so it is essential to consult a healthcare professional for a proper diagnosis if you suspect a B12 deficiency. If left untreated, severe B12 deficiency can lead to serious neurological and health problems, so timely diagnosis and treatment are crucial. Treatment typically involves vitamin B12 supplementation through injections, oral supplements, or dietary changes.

    Taking an oral supplement is a simple way to address vitamin B12 deficiency. There are many forms, including sublingual tablets, liquid and chewables. Consult with one of our nutrition advisors to find out what type of vitamin B12 is best for you.
