Vitamin B12

Vitamin B12 helps the body make DNA and red blood cells. In addition, neurons in the brain require this vitamin to function properly. Vitamin B12 is involved in serotonin production. Thus, low levels of the vitamin may increase the risk for clinical depression. In a study of older females, researchers found that those with vitamin B12 deficiencies were twice as likely to develop depression as those without deficiencies. Another study concluded that individuals with high vitamin B12 levels were more likely to recover from major depressive disorder than those with lower levels. Vitamin B12 may also help prevent macular degeneration.

Those who are pregnant must have adequate vitamin B12 levels. This is particularly vital because having adequate vitamin B12 reduces the risk of miscarriage, low birth weight, premature birth, and neural tube congenital disabilities. In terms of brain health, vitamin B12 may help improve memory and slow the cognitive decline associated with aging and dementia. Healthy adults are advised to consume 2.4 micrograms of vitamin B12 each day. Vitamin B12 supplements have quite a few potential medication interactions. For instance, they may interact with metformin, proton pump inhibitors, and histamine H2 receptor antagonists. Thus, individuals should review their medications with a doctor or pharmacist before taking vitamin B12 supplements.
