Head-to-head clinical comparison of therapeutic indices and safety profiles.
Multivitamin preparation providing essential vitamins (A, D, E, K, C, B1, B2, B3, B5, B6, B12, biotin, folic acid) as cofactors for various metabolic reactions, including energy production, collagen synthesis, antioxidant defense, and blood coagulation.
M.V.I.-12 Adult is a multivitamin combination that supplies essential vitamins (A, D, E, C, B1, B2, B3, B5, B6, B12, folic acid, biotin) to maintain normal metabolic functions, act as cofactors in enzymatic reactions, and support cellular respiration, antioxidant defense, and erythropoiesis.

Highly variable by component; e.g., ascorbic acid: 8-40 days (depletion), thiamine: 9-18 days, pyridoxine: 2-3 weeks, fat-soluble vitamins: vitamin A: 2-3 months (liver stores), vitamin D: 15-25 days, alpha-tocopherol: 17-19 days, vitamin K: 2-3 hours (short). Clinical context: half-life reflects tissue storage and turnover; chronic dosing leads to accumulation for fat-soluble vitamins.
Variable by component: e.g., thiamine 9-18 days (tissue stores), vitamin C 10-20 days (depletion), vitamin A 50-100 days (liver stores). Clinical context: half-lives reflect slow depletion; daily dosing maintains plasma levels.
Vitamins are metabolized in the liver (e.g., vitamin A to retinoic acid) and other tissues; some undergo hepatic hydroxylation (e.g., vitamin D), conjugation (e.g., folic acid to tetrahydrofolate), or oxidation (e.g., pyridoxine to pyridoxal phosphate).
Vitamins are metabolized via various pathways: water-soluble vitamins (B-complex, C) are minimally metabolized and excreted renally; fat-soluble vitamins (A, D, E) are stored in tissues and hepatically metabolized; folic acid is reduced to tetrahydrofolate by dihydrofolate reductase.
Renal: water-soluble vitamins (B-complex, C) are primarily excreted unchanged in urine; fat-soluble vitamins (A, D, E, K) are excreted in feces via bile. % varies by vitamin: e.g., thiamine 40-60% renal, ascorbic acid 50% renal; vitamin A >80% fecal.
Renal: water-soluble vitamins (B-complex, C) excreted in urine; fat-soluble vitamins (A, D, E, K) undergo biliary/fecal excretion. Specific percentages vary per component; e.g., vitamin C ~50% renal, thiamine ~30-70% renal as metabolites.
Variable: vitamin A (retinol) bound to retinol-binding protein (90-95%); vitamin D (25-hydroxycholecalciferol) to vitamin D-binding protein (50-60%); vitamin E (alpha-tocopherol) to lipoproteins (90%); vitamin K to albumin (50-80%). Water-soluble vitamins: minimal binding (<10%).
Vitamin A: 100% (retinol-binding protein, albumin). Vitamin D: 85-90% (vitamin D-binding protein). Vitamin E: ~90% (lipoproteins). Vitamin K: ~99% (lipoproteins). B-complex: low binding (<5-30%). Vitamin C: 24% (albumin).
Not applicable as a mixture; individual vitamins vary: vitamin A: 0.5-1.5 L/kg (liver storage), vitamin D: 0.5-1 L/kg, vitamin E: 5-10 L/kg (adipose tissue), vitamin C: 0.3-0.5 L/kg, B-complex: 0.2-0.5 L/kg. Clinical meaning: reflects distribution into tissues and storage compartments.
Variable: water-soluble vitamins confined to extracellular fluid (0.2-0.3 L/kg); fat-soluble vitamins larger due to adipose storage (e.g., vitamin D ~1.5 L/kg). Overall mean ~0.5 L/kg reflecting mixed distribution.
IV only (M.V.I. Adult is for IV use; oral multivitamins have variable bioavailability: water-soluble ~50-90%, fat-soluble 20-50% depending on formulation and food). Not applicable as oral product for this monograph.
Intravenous: 100%. Oral: not applicable; formulation is for IV use only. If extrapolated from oral vitamin absorption: variable (e.g., thiamine 5-10%, vitamin C 70-90%).
No dose adjustment required for renal impairment. Use with caution in patients with severe renal dysfunction due to potential aluminum accumulation from excipients.
No dose adjustment required for renal impairment.
No specific dose adjustment for hepatic impairment. Use with caution in patients with severe hepatic dysfunction due to risk of vitamin accumulation and toxicity.
No specific adjustment; use caution in severe hepatic impairment.
For children aged 11 years and older: same as adult dose (10 mL IV once daily). For children 2 to 10 years: 5 mL IV once daily. For infants and children under 2 years: use M.V.I. Pediatric formulation. Administer as infusion over at least 2 hours.
Children 11 years and older: same as adult. Children under 11: 5 mL (one-half vial) daily.
No specific dose adjustment recommended. Standard adult dose (10 mL IV once daily) is appropriate unless significant comorbidities or polypharmacy warrant caution. Monitor for adverse effects due to potential age-related decline in organ function.
No specific adjustment; monitor for toxicity in elderly due to potential multivitamin accumulation.

Hypersensitivity reactions (including anaphylaxis) have been reported; contains aluminum (may be toxic with prolonged use in renal impairment); vitamin K can counteract anticoagulant therapy; vitamin A (retinol) hepatotoxicity with high doses; vitamin D toxicity with excessive doses; folic acid may mask pernicious anemia.

No specific food interactions. However, M.V.I. ADULT contains vitamin K; patients on warfarin should maintain consistent vitamin K intake. Avoid alcohol as it can affect vitamin metabolism.
No specific food interactions for intravenous administration. However, if transitioning to oral nutrition, consider that this product contains fat-soluble vitamins (A, D, E, K) which require dietary fat for absorption. Avoid excessive intake of vitamin K-rich foods (e.g., leafy greens) if on warfarin.
M.V.I. ADULT contains multiple vitamins and minerals. At recommended doses, most components are considered safe during pregnancy. However, high dose vitamin A (>10000 IU/day) is teratogenic in first trimester. Vitamin D excess may cause fetal hypercalcemia. No specific trimester risks for standard doses.
M.V.I.-12 ADULT is a multivitamin preparation. At recommended doses, no increased risk of congenital anomalies has been reported. However, high doses of vitamin A (retinol) can be teratogenic; this product contains retinol 3300 IU, which is below the teratogenic threshold (<10,000 IU/day). Use during pregnancy is generally considered safe when following recommended intakes.
M.V.I. ADULT components are excreted into breast milk in amounts that are generally considered safe. No specific M/P ratio available. Use with caution to avoid excessive maternal intake of fat-soluble vitamins.
The vitamins in M.V.I.-12 ADULT are normally present in breast milk and are considered compatible with breastfeeding at recommended doses. No specific M/P ratios are available for the combination product; individual vitamins have variable transfer. Caution with vitamin A doses exceeding 10,000 IU/day.
No dose adjustment required for M.V.I. ADULT during pregnancy. Standard recommended daily allowances apply.
Pharmacokinetic changes in pregnancy (e.g., increased plasma volume, renal clearance) may require increased intake of water-soluble vitamins. However, for M.V.I.-12 ADULT (a multivitamin for injection), standard dosing is typically appropriate. No specific dose adjustment recommendations are established; use as directed for supplementation to meet increased demands.
