The British Obesity and Metabolic Surgery Society (BOMSS) recommends intramuscular vitamin B12 injection every three months.

Bariboost bariatric multivitamin can be safely taken with the recommended injection. If you are worried about taking too much vitamin B12, it is highly unlikely that you will take too much vitamin B12 from supplements. Vitamin B12 is a water-soluble vitamin, which means it dissolves in water and is quickly absorbed by your body. It is stored in the liver and any excess vitamin B12 your body doesn’t need is excreted via urine.

Vitamin B12 is generally considered safe, even when taken in high doses as your body can only absorb a fraction of B12 supplements. Bariboost multivitamin contains 500 mcg of vitamin B12 and a healthy person will only absorb about 10 mcg (absorption is only about 2% at doses of 500 mcg). Those of us who have had bariatric surgery may absorb less as these surgeries can result in the loss of cells that secrete intrinsic factor which is a protein in the stomach needed to absorb vitamin B12.

Adults require 2.4 mcg daily. There is currently no Tolerable Upper Intake Level (UL) established for vitamin B12 due to its low level of toxicity.
