Vitamin B12 Deficiency Facts: Vitamin B12, often called cobalamin, is essential in certain bodily functions such as making red blood cells, brain function, and DNA synthesis. Unlike other vitamins, B12 is naturally found only in animal-based foods, so the vegetarian population is at higher risk of deficiency.
Vitamin B12 present in fruits, vegetables, and grains is absent, so the vegetarians forgo many direct sources of the vitamin. While some B12 may come from dairy products or fortified foods, stricter vegetarians consuming minimal dairy would face a higher deficiency risk.
Fatigue, weakness, dizziness, and pale skin are some of the early signs of Vitamin B12 deficiency. These symptoms are usually ascribed to stress or lifestyle, so most vegetarians never suspect B12 deficiency until they find out the deficiency in its advanced form.
Other than being important for nerve function, B12 deficiency can present a number of signs, such as tingling sensations in the hands and feet, memory impairment, changes in mood, and difficulty concentrating. If left untreated, prolonged deficiency can even result in irreversible nerve damage.
Since natural sources from plants are out of the question. All vegetarians are strongly encouraged to take either B12 supplements or B12-fortified foods. Including breakfast cereals, other plant-based milks, and nutritional yeast. This can make for regular intake so that vitamin levels in the body can be maintained.
Routine blood tests can catch B12 deficiency in its early stages. Subjecting oneself to analysis is particularly important for vegetarians on a restrictive diet. Such people should go for blood tests every now and then and consult their healthcare workers on proper supplementary doses.
