Description
Some individuals are at an increased risk of vitamin B-12 deficiency if they do not produce enough stomach acid or if they have autoimmune atrophic gastritis

The NHS notes that taking up to 2,000 micrograms daily is unlikely to cause harm in most people, though there is generally no benefit to such excessive amounts without confirmed deficiency

It delivers a high dose of the vitamin directly into the bloodstream, bypassing the gastrointestinal tract
