Vitamin B12 can help improve energy levels, support healthy brain function, and aid in red blood cell formation. But when you are deficient in this vitamin, you will have various health complications.

Nerve Damage

Long-term vitamin B12 deficiency can cause damage to the nerves, leading to numbness, tingling, and muscle weakness.


Vitamin B12 is essential for the production of red blood cells. Its deficiency can lead to anaemia, which can cause fatigue, weakness, and shortness of breath.

Cognitive Decline

Vitamin B12 plays a crucial role in brain functioning. The long-term deficiency can lead to cognitive decline, memory loss, and dementia.

Cardiovascular Disease

Vitamin B12 deficiency can lead to elevated levels of homocysteine, which is a risk factor for cardiovascular disease.


Another long-term health impact of vitamin B12 deficiency is infertility, which can affect both males and females.


Long-term deficiency of vitamin B12 can also lead to decreased bone density, which can increase the risk of osteoporosis.


Vitamin B12 is also involved in the production of neurotransmitters that regulate mood. Deficiency can lead to depression and other mood disorders.


Considering the importance of vitamin B12, it is important to have it in the right amount through diet. Consult your doctor to know the steps you should follow to decrease the deficiency.
