7 Things About a Vitamin B12 Deficiency to Never Ignore

Your health depends on the food you eat, the environment you live in, your genes and your physical activity. You get most of the essential nutrients from your food, and every change in your dietary habits affects the nutrients your body absorbs.

The human body loses its ability to absorb vitamin B12, and you can easily become deficient.

Signs of vitamin B12 deficiency

Your body needs enough vitamin B12 to function properly. This vitamin takes part in the formation of red blood cells, while keeping you healthy. There are several signs of its deficiency, and we give you some of them:

1. Inability to stay awake

If you can’t stay awake, you may be dealing with numerous health conditions, including vitamin B12 deficiency. Make sure you get eight hours of sleep at night. If you still feel tired, maybe you should consider boosting your vitamin B12 intake. This vitamin helps form red blood cells, and these assist your body in multiple ways. You may feel tired because your body is not producing enough red blood cells.


The lack of vitamin B12 makes you dizzy. You should notice this right after standing up. Moreover, you will feel dizzy when going up and down the stairs.

2. Week muscles

There’s nothing worse than feeling week and tired. Strong muscles require enough red blood cells. The lack of vitamin B12 affects the production of these blood cells, and other cells don’t get enough oxygen, leaving your muscles weak.

Pins and needles

Muscle fatigue is not the only symptom. You are also likely to get that pins and needles sensation. It’s followed by numbness and electric shocks caused by damaged nerves. Each of these issues occurs as a result of low oxygen levels.

3. Memory loss

Your brain needs oxygen, too. Insufficient amount of oxygen results in foggy memory and other signs of poor memory function.

Boost your memory

Consult your doctor and do a blood test to determine if you lack vitamin B12. If that’s your case, take vitamin B12 supplements to boost your memory.

4. Pale skin

Your skin is pale and yellow because of the broken blood cells as they release bilirubin. The skin turns yellow in those dealing with jaundice, meaning you should consult your doctor before you do anything.

5. Smooth and red tongue

Do you have bumps on your tongue? If yes, congratulations, you are healthy. These bumps are also called papillae. You won’t have any bumps on your tongue if you lack vitamin B12.
