About this supplement
The B Vitamins and Energy Metabolism
B vitamins are a group of eight water-soluble vitamins that function as coenzymes in metabolic processes, particularly those related to energy production and normal neurological function. Unlike fat-soluble vitamins, they are not stored in the body in significant quantities, making regular intake important. While B vitamins share functional overlap in energy metabolism, each has distinct roles in specific biochemical pathways — which is why a complete, full-spectrum formula covering all eight matters.
Three Vitamins in Their Active Forms
Most B-complex supplements use standard, lower-cost forms of B vitamins that the body needs to convert before they can be used. B-COMPLEX uses the active forms for three of its key vitamins.
Vitamin B6 is included as pyridoxal-5-phosphate (P5P), the coenzyme form the body uses directly. Vitamin B12 is included as methylcobalamin, the active neurological form. Vitamin B9 is included as Quatrefolic® — a patented 5-methyltetrahydrofolate (5-MTHF) that is the biologically active form of folate. Standard supplements typically use folic acid, which requires conversion via the MTHFR enzyme. A significant proportion of the population carry genetic variants that reduce this conversion, making the active form a more reliable choice.
Beyond the Eight B Vitamins
B-COMPLEX goes further than a standard B vitamin formula by including four additional compounds with related metabolic roles: choline (25mg), inositol, para-aminobenzoic acid (PABA) and trimethylglycine (TMG, 25mg). These are included alongside the B vitamins to support the broader biochemical environment in which B vitamins function.
High-Strength Doses, Clearly Labelled
The B vitamins in this formula are included at high-strength doses. Vitamin B1 at 50mg (4,545% NRV). B2 at 50mg (3,571% NRV). B6 at 20mg (1,429% NRV). B12 at 50µg (2,000% NRV). Every dose is on the label.
Frequently asked questions
How many capsules are in the container?
90 capsules, a three month supply at the recommended dose of one capsule per day.
What makes this different from a standard B-complex?
Three of the eight B vitamins are included in their active coenzyme forms: B6 as P5P, B12 as methylcobalamin and B9 as Quatrefolic® 5-MTHF. The formula also contains choline, inositol, PABA and TMG alongside the eight B vitamins.
What is Quatrefolic® and why does it matter?
Quatrefolic® is a patented form of 5-methyltetrahydrofolate (5-MTHF), the biologically active form of folate. Standard supplements use folic acid, which the body needs to convert via the MTHFR enzyme. People with common MTHFR gene variants have reduced ability to make this conversion efficiently. Quatrefolic® bypasses that step entirely.
Can I take B-COMPLEX with other GetTested supplements?
Do not take B-COMPLEX together with other supplements containing Vitamin B6, as the combined intake could exceed safe levels. Several other GetTested products contain B6 — check the labels before combining.
Is there a warning I should know about?
Yes. Long-term intake of this amount of Vitamin B6 (20mg per day) may lead to mild tingling and numbness. This is stated on the label and is a regulatory requirement at this dose. If you experience any of these symptoms, discontinue use and consult a healthcare professional.
Who should not take B-COMPLEX?
For adults only. Not suitable for children or adolescents. Not recommended during pregnancy or breastfeeding unless advised by a healthcare professional. Do not combine with other supplements containing Vitamin B6. Consult a healthcare professional before use if you are taking medication.
How should I store it?
In the original sealed packaging, in a dry place away from light at +5 to +25°C.
