Symptoms of B12 Deficiency
Common symptoms of B12 deficiency include fatigue, pale skin, shortness of breath, constipation, depression, and poor concentration. Other symptoms include loss of appetite, weight loss, nerve problems, and anemia.
Causes of B12 Deficiency
B12 deficiency is usually caused by a lack of the vitamin in the diet, low levels of stomach acid, or an inability to absorb the vitamin from food. People who are vegan or vegetarian may be more at risk of developing a deficiency due to their diets lacking in animal proteins.
Quick Remedies for B12 Deficiency
The quickest way to remedy a B12 deficiency is to take a B12 supplement. B12 supplements can be found in tablet, capsule, or injectable form. It is important to talk to a healthcare professional before taking a supplement, as there may be potential side effects or interactions with other medications.
Eating foods that are rich in B12, such as animal proteins, fortified cereals, and nutritional yeast, can also help to quickly increase B12 levels. Vitamin B12 injections may also be prescribed by a doctor to quickly increase B12 levels in the body.
