6. You feel uneven and dizzy
If it feels like the ground you are walking on is uneven or things around you look like they are shifting and you simply feel dizzy, you could be suffering from a lack of vitamin B12.
Several studies have found that people who have low levels of vitamin B12 often feel as if they are dizzy and are more prone to vertigo, a condition that impacts the sense of balance and can make you feel as if you are off-kilter, wobbling, or as if you are rocking on a boat on wavy water.
