How it works
"Vitamin B12 is a cofactor in chemical reactions in the body related to cell metabolism and DNA. Deficiencies in vitamin B12 therefore can be very consequential and severe. Causes of vitamin b12 deficiency can include low dietary intake, autoimmune conditions, malabsorption, surgery, contraceptive and hormone use, pregnancy, genetic causes, or drug interactions (metformin, proton pump inhibitors, and histamine H2 receptor agonists). Symptoms of vitamin b12 deficiency include fatigue, lack of energy, nervous system issues, and psychological dysfunction. Slow thinking, confusion, changes in memory, depression, and acute psychotic states may be psychiatric symptoms attributed to vitamin B12 deficiency."
Pregnancy
Vitamin B12 is safe for pregnancy. From UpToDate: "Water soluble vitamins cross the placenta. Absorption of vitamin B12 may increase during pregnancy. Vitamin B12 requirements may be increased in pregnant women compared to nonpregnant women."
Lactation
Vitamin B12 is safe for lactation, and exists in breastmilk. Vitamin B12 requirements may be higher in lactating women.
