B12 Vitamin Deficiency – 7 Warning Signs

1. Muscle Weakness

If you have difficulties carrying your grocery bags, that means that your muscles are deprived of the convenient amount of oxygen. B12 deficiency and irregular oxygenation to muscle cells can cause sluggishness and muscle weakness. This may be a good reason why you cannot carry your grocery bags.

2. Dizziness

A frequent lightheadedness/dizziness or bouts of vertigo are warning signs of B12 vitamin deficiency. You may get dizzy standing up from the chair too fast or walking up and down the stairs.

Consult your doctor if you notice symptoms of vertigo because this situation could be dangerous. In any case, you will receive convenient treatment for the deficiency of the vitamins.

3. Forgetfulness

If you forget ordinary things on a daily basis that does not necessarily mean you have dementia, but lack of B12 vitamin. Also, most of the people think that they have dementia or Alzheimer’s, but they have lack of B12 vitamin.

To check this condition, you should do a blood test, and with appropriate supplements, you can improve your memory.

4. Eye Problems

Long-term deficiency of B12 vitamin can cause vision changes or damages. Even rarely, an optic neuropathy can be caused by B12 deficiency which will result in doubled, blurred or reduced central vision, tracers or shadows, and light sensitivity. However, supplements can help to restore the vision.

5. Pale Skin

There was a time when you used to have rosy cheeks, but now your skin is pale. This is probably caused by the B12 deficiency which indicates lack of erythrocytes. At this point, the production of bilirubin is on a higher level which replaces the rosy cheeks with pale skin.

6. Pins and Needles

Paraesthesia or Pins and Needles is caused by a deficiency of the B12 vitamin. If you have experienced prickling, tingling, numbing sensation in the feet and hand or through all the body, and electric shock waves it is because of the nerve damage that is caused by B12 deficiency.

If you are B12 deficient means that your production of erythrocytes is reduced which results in low level of oxygen in the nerve tissues.

7. Unexplained Fatigue

Even if you are sleeping as you should, you constantly feel tired. In fact, this is another B12 deficiency signal. Therefore, the unexplained fatigue occurs because of the reduced production of erythrocytes in the body, that results in poor amount of oxygen transported to the organs.

Vitamin B12 Health Benefits

In order to understand the B12 vitamin significance, read the following list of the health benefits:

1. Prevents Nerve Damage

Myelin sheath is the natural cover of the nerves, and its initial purpose is to secure them from free radical damage and toxins. If the nerves do not have this covering, they can be killed and damaged which will provoke nerve-related disorders.

This is happening because the dead nerves are discontinuing the transmission of signals from and to the brain.

2. Prevents Stroke and Heart Disease

If the heart disease is the principal cause of death, everyone should consider taking serious measures for protection. It is discovered that homocysteine’s increased levels have a higher risk factor than cholesterol for heart disease.

This can produce inflammation if there is a deficiency of the B12 vitamin. Moreover, this vitamin reduces the homocysteine’s level and also the risk of stroke and heart disease.

3. Helps Digestion

Vitamin B12 helps in the creation of digestive enzymes, and it is helpful with the breakdown of food and supports a healthy metabolism. It can help remove the harmful bacteria in your digestive tract, and also can help promote the healthy bacteria in your gut.

For patients with osteoporosis or anyone who has problems with bone conditions, the B12 vitamin is recommended. As already mentioned, B12 vitamin may reduce homocysteine’s levels, that makes it a great supplement for those patients.
