Food in.
Energy out.
B vitamins are how your body turns food into fuel. ZETA B-Complete gives you all eight — with folate, B2, B6 and B12 already in their active forms, ready to work.
“The key methylated B-vitamins are critical because they are more bioavailable, meaning the body’s ability to use the supplement completely. From their extensive antioxidant effects, to their impact on maintaining healthy homocysteine levels, optimized B-vitamin levels sustain healthy hearts, blood cells and neurologic function.”

The B story
Eight B’s. One team.
B vitamins help turn food into energy. This formula includes active forms to support how your body uses them.
Folate · B9
Methylfolate is an active form of folate. Quatrefolic® supplies it as a glucosamine salt.
Thiamine · B1
A fat-soluble derivative of thiamine, included alongside thiamine HCl.
Vitamin B6
The active coenzyme form of vitamin B6, which supports normal nervous system function.*
Vitamin B12
An active form of B12 that supports normal red blood cell formation and nervous system function.*
All eight B’s. Zero noise.
Other ingredients: Capsule (hypromellose and water), stearic acid, magnesium stearate, silica.
Quatrefolic® is a registered trademark of Gnosis S.p.A. Produced under U.S. Patent 7,947,662.
- Take 1 capsule once or twice a day — or as directed by your healthcare professional.
- Best timing: the morning. B’s are part of your energy system — give them the day to work.
- Every day matters more than timing. Your body doesn’t store most B’s, so steady wins.
Riboflavin note
Riboflavin (B2) can make urine appear bright yellow. Contact a healthcare professional about unexplained changes or other symptoms.

Why methylfolate
Folate is provided as 5-methyltetrahydrofolate (5-MTHF), which bypasses metabolic steps to folate bioactivity. Research shows large doses of folic acid can "force" its conversion to the active form, but 5-MTHF may be the preferred form to replenish folate — especially for people with digestive challenges or genetic variations in folate metabolism (such as MTHFR). Red blood cell folate has been shown to be higher after supplementation with 5-MTHF compared to folic acid and placebo; in one pharmacokinetic study, 5 mg of 5-MTHF produced plasma 5-MTHF levels 700% greater than folic acid.*
Why benfotiamine
Benfotiamine (S-benzoylthiamine O-monophosphate) is a safe, fat-soluble analog of thiamine — the most potent of a class of thiamine compounds found in small amounts in the Allium family (garlic, onions). Its structure lets it diffuse easily through cell membranes, then become active inside. One study showed it raised blood and tissue thiamine at least five times higher than the water-soluble salt and remained bioavailable up to 3.6 times longer. Benfotiamine increases transketolase activity, helping steer glucose metabolism away from pathways that form advanced glycation end products (AGEs).*
Why P5P
Pyridoxal-5′-phosphate is the active coenzyme form of B6. In a study of patients with impaired liver function, only 33% of those given pyridoxine HCl showed a rise in plasma P5P — while every patient given P5P did.*
