Vitamin B12 plays several roles in your body. Not only does it help increase energy and stimulate metabolism, but it also works for the development of nerve and brain cells, while also facilitating the production of DNA.
Since our bodies cannot produce vitamin B12, the best way to get sufficient amounts of this vital nutrient is through natural sources such as animal products consisting of shellfish, eggs, poultry, and some types of dairy products. That said, while certain vegetables and legumes do contain vitamin B12, they don’t provide as many nutrients as non-vegetarian foods.
