There are different forms of B6 and B12, and no actual relationship between vitamins that share the "B" name. Almost all categories invented in nutrition are bunk, and each individual molecule affects us differently. P5P (B6) has different effects than the usual pyridoxine hcl (B6). Methylcobalamin (B12) has different effects than Cyanocobalamin (B12). Sometimes different isomers of the same molecule affect us differently. This study is behind a paywall, but the abstract doesn't seem to mention what forms were used. How unfortunate.
