Vasanthasree Nair MBBS Last updated on 13th Jan, 2026 Introduction Its common to hear conversations about low vitamin B12, but seeing a high vitamin B12 level in your blood test results can be unexpected

B12 injections help restore your vitamin levels to prevent water loss on your skin and enhance your protection against irritants
The Recommended Dietary Allowance (RDA) is in fact not the bodys daily requirement exactly, but rather the amount of vitamin B12 which according to the recommendations of the corresponding organisations should suffice to cover the minimum daily requirement of 97.5% of healthy people
based on an adult requiring 2.4 mcg/day this provides the equivalent of 417 days of B12
