Vitamin B12 deficiency, or hypocobalaminemia, refers to low levels of this vitamin in the blood.
It presents with many signs and symptoms, many of which are related to psychological and emotional health.
The most common causes are reduced consumption, use of certain drugs, genetics, nutritional deficiencies, poor absorption from the stomach and intestines, chronic inflammation of the stomach, intestinal parasites, etc.
Because this vitamin is essential for healthy brain function, synthesis of DNA, nerves, and blood cells, and for a healthy immune system.
It is found in animal products such as meat, dairy, eggs and shellfish.
Therefore, if left untreated, vitamin B-12 deficiency can lead to serious blood disorders and neurological disorders. Here are the 5 most common warning signs of vitamin B-12 deficiency.
Unexplained fatigue
If you sleep well but feel tired and lack energy all the time, your body may be deficient in this vitamin. The reason for this is a lack of red blood cell production, one of the functions of B12. In this case, the delivery of oxygen to the organs is hindered and leads to fatigue.
Dizziness
B12 deficiency can cause dizziness and lightheadedness, as well as a feeling of unsteadiness when standing up too quickly from a sitting position or walking up or down stairs.
Forgetfulness
Low B12 levels can make you forgetful all the time. You might suspect it’s early-onset dementia, but chronic, nonspecific forgetfulness is a common symptom of this deficiency. However, you can improve your memory and increase your B12 intake by taking supplements.
Pins and needles
B12 deficiency often causes pins and needles all over the body because the vitamin affects the production of red blood cells and controls oxygen levels. Nerve damage can cause numbness or electrical shock waves.
Muscle weakness
If the muscles do not receive enough oxygen from the red blood cells, the muscles become weak and slow.
But what to do?
You should eat more dairy, eggs, poultry, and animal protein sources and take a B12 supplement. We recommend using its form known as methylcobalamin, which is better absorbed by the body.
