Overview
•100 mcg cyanocobalamin oral daily provides low absorbed dose due to saturable intrinsic-factor mechanism.
•High-dose oral B12 (>200 mcg) used clinically for deficiency correction; 100 mcg is below typical therapeutic range.
•Renal impairment may require monitoring due to potential aluminum content in some formulations.
•Pregnancy: deficiency increases adverse outcome risk; supplementation benefit depends on baseline status.
•Evidence limited for long-term use at this exact low dose in non-deficient adults.
