What is Vitamin B12?
Vitamin B12, also known as cobalamin, is an essential vitamin required by the body for making red blood cells, supporting normal nerve function, and producing DNA. The body cannot produce Vitamin B12 itself, so it must be obtained from diet or supplements.
Why should you test Vitamin B12 levels?
Testing Vitamin B12 levels can be useful for people experiencing fatigue, those who are vegan or vegetarian, or individuals suffering from anemia or neurological symptoms. It helps determine if there is a deficiency or an excess, which may indicate dietary patterns or health conditions requiring attention.
What does it indicate?
Vitamin B12 levels in the blood indicate whether your body has sufficient amounts of this crucial vitamin to carry out essential functions.
What does a high Vitamin B12 level mean?
A higher than normal level of Vitamin B12 can indicate certain medical conditions such as liver disease. It is important to investigate this further with a healthcare professional.
What does a low Vitamin B12 level mean?
A low level of Vitamin B12 can indicate a deficiency, which may lead to anemia, fatigue, weakness, constipation, loss of appetite, and weight loss. Neurological problems may also occur, such as numbness and tingling in the hands and feet.
