Vitamin B12 is an extremely important nutrient required by the body. Since the body is not able to produce the vitamin B complex internally, it must be derived from food sources and nutrients. Vitamin deficiency can have all kinds of negative impacts on the human body and not getting enough of vitamin B12 can lead to anaemia. If the deficiency is mild, there will not be any apparent symptoms. However, if there is an intense deficiency, it may cause various disruptions of metabolic processes such as physical weakness, heart palpitations, disorders of the digestive system (constipation, gas or diarrhoea for example), paleness of skin, nerve problem (muscle weakness and tingling sensations), loss of vision and even mental disorders such as depression, loss of memory and mood swings. Vitamin B12 is found mostly in animal-based foods and those who are vegan or pure vegetarians are highly prone to this vitamin deficiency. You should consult a dietician or nutritionist to know what kind of diet to follow or to get a prescription for the right kind of vitamin supplements for receiving an adequate amount of the vitamin B complex. In order to treat and prevent this vitamin deficiency, make sure you consume enough meat, eggs and dairy products. If you are a vegetarian, you need to opt for vitamin B12-fortified grains or take vitamin B complex supplements. This is especially necessary for those who are older as the risk of deficiency increases with age.
