Mood Changes
Mood changes can also happen if you experience vitamin B12 deficiency. In fact, some studies have shown a link between low B12 levels and brain or mood disorders such as dementia or depression. This is because a low level of vitamin B12 in the body would lead to a higher level of homocysteine, which would damage your brain tissue and affect signals from and to your brain section responsible for mood changes. Thus, taking B12 supplements would be helpful in improving your mood. [6]
