Synergy
What is happening. Riboflavin (B2) is needed for the conversion of B6 to its active coenzyme form PLP.
Mechanism. Riboflavin's active form FMN is a cofactor for pyridoxine 5'-phosphate oxidase, which converts pyridoxine-5-phosphate to pyridoxal-5-phosphate (PLP, active B6).
Recommendation. Take as part of a B-complex for mutual support.
