6. Anxiety

Many people experience anxiety, often paired with mood swings and even depression. If there's a logical reason for the anxiety, the symptoms typically lessen over time. However, signs of anxiety for no good reason may stem in part from a lack of vitamin B12. Vitamin B12 is necessary for good mental health, including the essential processes and functions of the brain. It also promotes positive emotional and mental health. Vitamin B12 gives people the necessary energy to face the day with a positive outlook.
