Also known as cobalamin, B12 is an essential vitamin for good health. It allows your body to function properly by helping it convert the food into glucose and giving you energy.

Vitamin B12 is one of the eight B vitamins and it enables the proper function of the brain, nerves, blood cells, and many other parts of your body. It can be found in meat, dairy products, fish, but also in supplements.

Most people decide to increase the consumption of items rich in B12 vitamins due to a condition called vitamin B12 deficiency. Aside from treating vitamin B12 deficiency, this vitamin is also good for:

  • keeping the body's nerve and blood cells healthy
  • helping production of DNA, the hereditary material in all cells
  • preventing megaloblastic anemia that can make people weak
  • red blood cells formation
  • regeneration of bone marrow

Your body doesn't produce vitamin B12 so it's essential to get it from food or supplements. So how much vitamin B12 should a person take?
