What is Vitamin B12?
Vitamin B12 (also known as Cobalamin) is an essential B vitamin vitamin that your body needs but cannot produce. It is one of 8 B vitamins crucial for nerve tissue health, brain function, and the production of red blood cells. It is the largest and most structurally complicated vitamin and is water-soluble, like all other B vitamins. This means it can dissolve in water and travel through the bloodstream.
Signs of Vitamin B12 Deficiency
A deficiency can occur when levels of vitamin B12 become too low to meet the demands of the body which can lead to a number of symptoms and can even progress to irreversible neurological issues if left untreated. Vitamin B12 deficiencies are becoming increasingly more common with symptoms including:
- Tiredness & fatigue
- Mood changes & depression
- Brain fog & memory problems
- Pale Skin
- Low energy or anemia
- Low iron levels
Unlike some other B vitamins, B12 is not found in any plant food other than fortified cereals which makes it difficult for people following a strict vegetarian diet to get the necessary amount of vitamin B12.
