Basis: This is the phosphorylated active coenzyme itself, not a mineral/acid salt of pyridoxine
Why this tier: The biochemical logic (already the active coenzyme, bypassing conversion) is sound in principle, but no confirmed comparative human trial supports a specific tier ranking over pyridoxine HCl -- do not assert P5P superiority without a real study.
