                    Cautions

                    Contains milk, soy, and carmine

                    Daily folic acid administration (>0.1 mg/day), may obscure detection of B12 deficiency (specifically, the administration of folic acid may reverse the hematological manifestations of B12 deficiency, including pernicious anemia, while not addressing the neurological manifestations); L-methylfolate may be less likely than folic acid to mask vitamin B12 deficiency

                    Pregnancy & Lactation

                    Pregnancy Category: C

                    Lactation: Unknown whether distributed in breast milk

                    Pregnancy Categories

                    A: Generally acceptable. Controlled studies in pregnant women show no evidence of fetal risk.

                    B: May be acceptable. Either animal studies show no risk but human studies not available or animal studies showed minor risks and human studies done and showed no risk.

                    C: Use with caution if benefits outweigh risks. Animal studies show risk and human studies not available or neither animal nor human studies done.

                    D: Use in LIFE-THREATENING emergencies when no safer drug available. Positive evidence of human fetal risk.

                    X: Do not use in pregnancy. Risks involved outweigh potential benefits. Safer alternatives exist.

                    NA: Information not available.

                    Provides nutritional requirements needed to restore metabolic processes associated with diabetic neuropathy to maintain blood flow by increasing nitric oxide resulting in vasodilation

                    L-methylfolate: Primary biologically active isomer of folic acid and the primary form of folate in circulation; folic acid is a precursor of tetrahydrofolic acid, which is involved as a cofactor for transformylation reactions

                    Pyridoxal 5′-phosphate (PLP): Active form of vitamin B6

                    Methylcobalamin: One of 2 forms of biologically active vitamin B12

                    Absorption

                    Peak plasma time: 1.3 hr

                    Peak plasma concentration: 129 ng/mL

                    AUC: 383 mcg•h/mL

                    Distribution

                    Protein bound: 56%

                    Vd: Wide distribution, RBC levels of folate remain elevated for periods in excess of 40 days following discontinuation of supplementation

                    Elimination

                    Half-life: 3 hr
