Vitamin B<sub>12</sub> is a water-soluble vitamin, so any unused amount will exit the body through the urine. Generally, up to 1000 mcg a day of an oral tablet to treat a deficiency is considered safe. The Institute of Medicine states “no adverse effects have been associated with excess vitamin B<sub>12</sub> intake from food and supplements in healthy individuals.” However, it is important not to start a high-dosage supplement of any kind without first checking with your doctor. <ref>https://www.hsph.harvard.edu/nutritionsource/vitamin-b12/</ref> | Vitamin B<sub>12</sub> is a water-soluble vitamin, so any unused amount will exit the body through the urine.
