Why is Vitamin B 12 Essential

All B vitamins play a key role in converting food into fuel for energy and helping the body metabolize proteins and fats. Additionally, they are essential to keeping your skin, eyes, liver, and hair healthy, besides supporting the functioning of your nervous system.

  • Vitamin B12 is integral to metabolism and cell functioning. It supports the metabolism of amino acids and fatty acids. If you are a vegetarian or vegan, then you could be at a risk of vitamin B12 deficiency. A long-term deficiency poses a high risk of permanent damage to the brain. It could even damage the central nervous system. For someone who does not eat meat, it is important to incorporate foods that supplement your diet with cobalamin or B12.
  • B-12 supports various vital physiological processes of the body, including bone marrow health, nervous system, brain function, blood formation, and DNA synthesis. The recommended dose of vitamin B-12 ranges from 2-3 to 4-7 micrograms per day.
  • The water-soluble Vitamin B-12 is found primarily in animal foods and fortified cereals.
  • Vitamin B12 helps the body maintain healthy nerve cells. A deficiency could result in damage to the nervous system.
  • Vitamin B12 works with folic acid or vitamin B9 to produce red blood cells, facilitate absorption of iron, and produce immune-boosting compound S-adenosylmethionine (SAMe).
  • The body uses vitamin B12 to produce, protect, and repair its genetic material – the DNA and RNA. This is essential to slowing down the process of aging and reducing cancer risk. The absorption of Vitamin B12 and folate helps in DNA metabolism.

Symptoms of Vitamin B12 Deficiency

Deficiency of B12 can cause all sorts of changes in the body:

  • Diarrhea
  • Fatigue
  • Numbness
  • Nervousness
  • Breathlessness
