For optimal efficacy, it is recommended that all B vitamins be taken as a B complex, as they work together and are interdependent in many ways. When a high intake of a single B vitamin is desired, it is best combined with a B complex.

Vitamin B Complex Active contains a generous dose of all B vitamins and related substances. Here, biologically active (co-enzymatic) forms have been chosen whenever possible. This applies to vitamins B2 (sodium riboflavin-5'-phosphate, R-5'-P), B6 (pyridoxal-5'-phosphate, P5P), B12 (methylcobalamin and adenosylcobalamin, also known as dibencozide) and folate (5-methyltetrahydrofolate, 5-MTHF). Their advantage is that they do not need to be converted before they can be active as coenzymes in metabolism. Thus, they are the body's own forms and often the forms in which B vitamins are found in food.
