Vitamin B12


Vitamin B12 is vital in the production of DNA, nerves, and blood cells. It’s keeps your brain healthy and the immune system up and running smoothly. And when it comes to your metabolism, it plays a key role in converting nutrients to energy. Vegetarians, vegans and individuals over 50 almost all have B12 deficiency if not supplemented. The reason is because B12 is absorbed from animal products, and absorption through the stomach decreases with age or with use of antacids. Expecting and nursing women need the highest doses of vitamin B12 to ensure healthy fetal and neonatal development. B12 deficiency causes anemia, jaundice, dementia, personality changes, loss of dexterity, paresthesias, numbness and weakness. It is an under-diagnosed condition (only 29% of diagnosed patients had anemia in a Mayo Clinic study - PMID 8309266). We recommend supplementation based on risk factors and physiologic needs.
