Vitamin B12 is
essential for red blood cell formation, DNA
synthesis, and neurological function. Deficiency can
lead to severe health issues.
Symptoms
of B12 deficiency include fatigue, weakness, pale
skin, shortness of breath, dizziness, and tingling
in the hands and feet.
B12
deficiency can cause memory problems, difficulty
concentrating, mood swings, and even depression due
to its role in brain health.
Digestive
issues like nausea, loss of appetite, and weight
loss can occur. Some people may also experience a
swollen, inflamed tongue and mouth ulcers.
A
healthy individual should maintain a B12 level of
200-900 pg/mL. Levels below 200 pg/mL indicate a
deficiency needing medical attention.
B12 is
primarily found in animal products like meat, fish,
eggs, and dairy. Vegetarians and vegans should
consider fortified foods or supplements.
