Detailed explanation-1: -Two subgroups of vegans are at particular risk of B12 deficiency: long-term vegans who avoid common fortified foods (such as raw food vegans or macrobiotic vegans) and breastfed infants of vegan mothers whose own intake of B12 is low.

Detailed explanation-2: -A new study has found that those who choose vegan diet may be missing out on Vitamin B12 and may need supplements to avoid deficiency of the vitamin. Experts have said that Vitamin B12 is naturally found in meat, fish, dairy products and eggs – in short foods that vegans avoid.

Detailed explanation-3: -Unlike some other B vitamins, B12 is not found in any plant food other than fortified cereals. It is, however, abundant in many meats and fish, and in smaller amounts in milk and eggs. This makes it difficult for people following a strict vegetarian diet to get the necessary amount of vitamin B12.
