B Complex Ultra contains the entire spectrum of B vitamins to support adrenal and neurological functions.
It features activated forms of vitamins B2, B6, and B12; benfotiamine, a fat soluble, more physiologically
active form of thiamine; and folate as Quatrefolic®, which is proven to have greater stability, solubility, and
bioavailability over calcium salt forms of 5-MTHF.*

are biotransformed into their active coenzyme forms. B Complex Ultra contains vitamins B1 (thiamine), B2
(riboflavin), B6 (pyridoxine), and B12 (methylcobalamin) in their physiologically-active form making them easier
to absorb and “ready-for-use.” For example, in patients receiving pyridoxine HCl, only 33 percent responded
with an increase in plasma pyridoxal-5’-phosphate (P5P); however, the level increased in all of the patients
Folate is provided as 5-methyltetrahydrofolate (5-MTHF), which bypasses metabolic steps to folate bioactivity.
Despite research showing that folic acid and 5-MTHF have equivalent bioavailability and that supplementation
with large doses of folic acid can “force” its conversion to the more active form, 5-MTHF may be the preferred
form to replenish folate. This may be especially applicable to those with digestive challenges or genetic variations
in folate metabolism.[2-4] In this formula, 5-MTHF is provided as Quatrefolic—the glucosamine salt of 5-MTHF.
In vitro and in vivo studies have proven that Quatrefolic has greater stability, solubility, and bioavailability over
calcium salt forms of 5-MTHF. Folate is stored in small amounts in red blood cells (RBC), and RBC folate has
been shown to be higher after supplementation with 5-MTHF compared to folic acid and placebo. Likewise,
patients given 5 mg of 5-MTHF experienced plasma levels of 5-MTHF 700% greater than patients given folic
Another unique ingredient in this formula is benfotiamine (S-benzoylthiamine O-monophosphate), a safe, fatsoluble
analog of thiamine. One study showed that it not only raised blood and tissue levels of thiamine at least
five times higher than the water-soluble salt, but it also remained bioavailable after oral administration up to 3.6
times longer than thiamine salt. Benfotiamine is the most potent of a class of thiamine-derived compounds
present in small quantities in members of the Allium genus. The superiority of its biological activity compared
to thiamine rests in its structure—a thiazole ring opens to allow easy diffusion through a membrane and then
closes to become structurally active.*
Benfotiamine increases transketolase activity, thereby diverting from three natural, yet destructive metabolic
pathways: 1) it decreases the glucose metabolites that lead to the buildup of certain types of detrimental
advanced glycation end products (AGEs); 2) it normalizes protein kinase C activity; 3) it protects the retina
by preventing the activation of NF-kappaB therein. Research suggests it may also protect the kidneys and
endothelial cells. Benfotiamine is useful for replenishing thiamine, this may be especially true in individuals
that use the vitamin at a higher rate or in those with lifestyle habits that deplete it.*[9-11]
