Feature Summary

Enhanced B Complex is a one-per-day formula providing full-spectrum B vitamins in their metabolically active forms.* B vitamins are cofactors for many important mechanisms in the body, including healthy nutrient metabolism, energy production, growth and development, and liver function.* B vitamins also help support normal immunity, red blood cell production, iron metabolism, as well as healthy skin, hair, and nails.* This formula includes B vitamins in metabolically active forms, such as vitamins B12 (methylcobalamin) and B6 (pyridoxal 5’-phosphate), to maintain healthy nervous system function.* It also includes 50 mg of choline and 400 mcg of folate (Quatrefolic). In addition, this formula contains vitamins B1, B2, B5, and B6, and niacin, with additional support from biotin and inositol. This convenient all-in-one B complex is an ideal supplement to help support healthy metabolism, energy, and overall health.*

Adequate folate in healthy diets may reduce a woman’s risk of having a child with a brain or spinal cord birth defect.*1 Quatrefolic is an active form of folate at the cellular level, found in circulation and the only one to cross the blood-brain barrier.* It does not need to be converted to an active form by the enzyme methylene tetrahydrofolate reductase (MTHFR), known to have common single-nucleotide polymorphisms.*2 Quatrefolic acid administration has been associated with higher peak (6S)-5-MTHF levels than both folic acid and calcium 5-MTHF, even in individuals with high-functioning MTHFR polymorphisms.*2–4

Methylcobalamin is a cofactor for B12-dependent enzymes and has direct biological activity.* When combined with other B vitamins, it may help support various facets of health, though MTHFR status may impact the level of effectiveness.*5–8

Drug Interactions

Although several classes of drugs, such as aminoglycosides, anticonvulsants, bile acid sequestrants, and proton pump inhibitors, antihyperglycemic medications (Metformin), and acne therapy (isotretinoin) are known to either interfere with B12 absorption or function, there are no known negative interactions caused by B12 supplementation with any medication.9–12 Folate may decrease the effectiveness of phenobarbital, phenytoin, or primidone when given concurrently; it may also decrease the effectiveness of pyrimethamine.13 When taken with amiodarone, vitamin B6 may increase photosensitivity.14 Theoretically, riboflavin may decrease the effectiveness of tetracycline antibiotics.15 Niacin may decrease the effectiveness of uricosurics, antidiabetics, and thyroid hormones.16
