Milk
One cup of milk provides 124 calories and nearly 1,4 micrograms of vitamin B12, which is 54% of the daily value for vitamin B12. Milk is a highly effective treatment for vitamin B12 deficiency and is another excellent source for vegans seeking dietary alternatives. A small group study involving vegetarians with vitamin B12 deficiency found that daily consumption of 2.5 glasses of buffalo milk for two weeks significantly increased vitamin B12 levels. However, bovine milk is a more abundant source of vitamin B12 than buffalo milk. In addition, milk is rich in vitamin D, calcium, and proteins, thereby promoting your health.
