  • Essential for DNA synthesis + repair


Vitamin B12, also known as cobalamin, is a pivotal nutrient with a range of essential functions in the body, including energy production, cognitive function, and nervous system health. One of its key roles is aiding in the formation of red blood cells and the maintenance of a healthy nervous system. Vitamin B12 is crucial for DNA synthesis and proper neurological function, making it indispensable for overall well-being. Unlike many other vitamins, vitamin B12 is not naturally produced by plants or animals; rather, it's synthesized by certain bacteria and archaea. Humans rely on dietary sources or supplements to meet their vitamin B12 needs. 

Beyond its basic roles, vitamin B12 significantly impacts energy metabolism. It plays a vital part in converting food into energy by facilitating the breakdown of carbohydrates and fats. This makes vitamin B12 essential for maintaining energy levels and preventing feelings of fatigue or crashing. Vitamin B12 supports the myelin sheath, a protective covering around nerve cells that enhances the efficiency of nerve signal transmission. Its influence extends to mood regulation and cognitive health, as low levels of vitamin B12 have been linked to neurological symptoms like memory problems and mood ups and downs. Incorporating vitamin B12 into your diet is integral to supporting cellular energy production and maintaining a healthy nervous system.


  • 1 Vitamin B12 is one of the largest and structurally complex vitamins. It contains cobalt at its core, which is why it's often referred to as cobalamin. Its intricate structure is vital for its various functions in the body.
  • 2 Deficiency in vitamin B12 can cause a range of symptoms, like fatigue, weakness, anemia, and neurological issues.
  • 3 Primarily found in animal-derived foods such as meat, fish, eggs, and dairy products, it can be challenging for people following vegetarian or vegan diets to obtain adequate levels of vitamin B12 without supplementation.
  • 4 Vitamin B12 is involved in the synthesis of DNA, RNA, and neurotransmitters, making it essential for the proper functioning of every cell in the body.
  • 5 Vitamin B12 is unique among vitamins as it is primarily produced by certain bacteria and archaea rather than plants or animals. This microbial synthesis of vegan friendly B12 occurs in soil.
