Owing to the widely prevalent myth that vegans mostly suffer from B12 deficiency because of their strict diet, many vegetarians have decided not to become vegans. It is a common belief among the majority of the people that Vitamin B12 deficiency is mainly caused due to the absence of animal protein. However, as a matter of fact such a belief is completely baseless. So, all the interested vegetarians, who wish to become a true vegan, can now do so, without feeling unnecessarily worried or scared.
It would be completely incorrect to say that Vitamin B12 deficiency does not exist at all. To tell the truth, lots of people in this day and age are suffering from the Vitamin B12 deficit. But many fail to realize this, simply because they do not know the symptoms. The most common symptoms caused due to lack of Vitamin B12 in human body are weight loss, fatigue in addition to gastrointestinal problems, like diarrhea, stomach upset and constipation. Apart from these, there are few other symptoms such as confusion, memory loss and numbness, which are also very common among people, who have Vitamin B12 insufficiency in their body.
However, studies have found solid evidence that proves that veganism has nothing to do with Vitamin B12 deficiency. Thus, there is no need for vegans to include nutritional yeast in their diet or take supplementary pills in order to live healthy. A large amount of people wrongly belief that only animal-based foods like dairy products, eggs and meat are the best source for Vitamin B12. However, it has been found that people who survive merely on plant-based products normally possess sufficient amount of Vitamin B12 in their body.
Actually, Vitamin B12 is produced by coenzymes, which comes from bacteria, already present inside the human body, mainly inside the mouth. If you go by the views of many researchers, Vitamin B12 deficiency is not triggered because of poor diet but due to more serious digestive problems, such as celiac disease and Crohn’s disease. The lack of Vitamin B12 can be treated just by prescribing the patient to have Vitamin B12 supplements.
