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, at high-strength doses.

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 a 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.

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.
