Most of us tend to take vitamins for granted. We often don’t realize their importance until we start experiencing symptoms of deficiency.

Vitamin B12 is a water-soluble vitamin that plays essential roles in various bodily processes, including brain function, red blood cell formation, and DNA synthesis.

Although it’s easy to obtain vitamin B12 from our diet, some people may still develop deficiency due to various factors, such as impaired absorption, poor diet, or certain medications.

Here are the signs and symptoms that you should watch out for if you suspect that you’re missing B12:.

1. Fatigue and Weakness

One of the most common symptoms of B12 deficiency is fatigue and weakness, which occurs due to impaired formation of red blood cells that transport oxygen to your body’s tissues.

This can make you feel tired and weak even after getting enough rest.

2. Pale Skin

Vitamin B12 deficiency can also cause pale skin due to reduced red blood cell count.

3. Dizziness or Vertigo

B12 deficiency may lead to dizziness or vertigo, especially when standing up or changing positions.

4. Shortness of Breath

Lack of B12 can also result in shortness of breath, particularly during physical activity, as the body struggles to maintain oxygen supply to the muscles.

6. Tinnitus

Some people with B12 deficiency may experience ringing in the ears known as tinnitus.
