Our basic needs in general range from 2 to 2.4 micrograms every day. Non vegetarian foods provide enough of this (liver, fish, red meat). Eggs and chicken are good sources too but have a lower content. For vegetarians, dairy products are the only source. So they have to make it a point to consume enough
If milk and milk products are not consumed enough, vegetarians not on supplements by and large tend to be B12 deficient.
B12 deficiency has been prominently seen in kids too. Even if one starts eating
Therefore, experts and medical practitioners clearly highlight the major need for B12 supplementation amongst vegetarians in general, elderly and pregnant women whose needs are even greater than normal adults.
One must get oneself tested on suspicion of B12 deficiency or even as a part of routine health examination. Once the reasons behind the deficiency are clear, the appropriate form ( injection, oral, sublingual or nasal ) of supplementation, the dose and the length of supplementation can be decided.
