Feature Summary
Active B Complex provides the most biologically active forms and clinically relevant doses of a unique B vitamin combination. Quatrefolic folate provides (6S)-5-methyltetrahydrofolic acid (MTHF), the active form of folate at the cellular level, which is found in circulation and is the only form able to cross the blood brain barrier. This form of folate bypasses enzymatic conversion by methylene tetrahydrofolate reductase (MTHFR), an enzyme with common genetic polymorphisms known to impair activity. Quatrefolic acid administration has been associated with higher peak (6S)-5-MTHF levels than both folic acid and calcium 5-MTHF, with higher plasma folate levels even in those with high functioning MTHFR polymorphisms. It also shows a more rapid repletion of folate levels among pregnant women than folic acid, along with the ability to lower homocysteine without masking a B12 deficiency.1–4
In addition to superior folate bioavailability, Active B Complex contains superior forms of each B vitamin. Benfotiamine is a lipid-soluble form of vitamin B1 with higher bioavailability than thiamine. It is used in the treatment of diabetic neuropathy because it blocks several hyperglycemic pathways and prevents endothelial dysfunction.5–7 Riboflavin 5’-phospate and pyridoxal 5’-phosphate (PLP) are biologically active forms of B2 and B6. PLP is the most important member of the B6 group and is the active coenzyme for more than 100 enzymes, bypassing hepatic conversion to an active form.8 Active B Complex also provides clinically relevant doses of methylcobalamin, niacin, pantothenic acid, biotin, choline, and inositol.

Contraindications
No reports exist for neuropathies associated with pyridoxal 5’-phosphate, though doses of pyridoxine at 1-3 g per day have been associated with peripheral neuropathy when used in isolation.9 People sensitive to nicotinic acid may experience flushing of the skin that is generally mild and transient.
Drug Interactions
Although several classes of drugs are known to either interfere with B12 absorption or function, such as aminoglycosides, anticonvulsants, bile acid sequestrants, proton pump inhibitors, antihyperglycemic medications (Metformin), and acne therapy (isotretinoin), there are no known negative interactions caused by B12 supplementation with any medications.10–13 Metformin has been shown to deplete B12 and folate, and supplementation with B12 only in diabetics may be preferable.14
