Read complete mechanism
Vitamins and minerals act as cofactors, antioxidants, structural elements or hormone precursors (e.g. vitamin D endocrine axis). Pharmacological high-dose effects differ from nutritional repletion.
Days–weeks for repletion
Depends on stores and ongoing intake
ORAL / IM / IV (selected)
depends on GI integrity, food matrix and binders (e.g. calcium/iron interactions). Fat-soluble vitamins (A,D,E,K) accumulate; water-soluble generally renally cleared.
Pregnancy, lactation & diet
[Zinc Undecenoate] Folic acid preconception/first trimester critical. Iron/folate common in ANC. Avoid excess vitamin A. [Undecenoic Acid] Use only if potential benefit justifies potential risk; prefer agents with better reproductive data when alternatives exist.
Maternal repletion often appropriate; avoid megadoses.
