PYRITINOL HCL POWDER:
Pyritinol, also called pyridoxine disulfide, is an analog of Vitamin B6 (Pyridoxine HCl). It was developed by Merck Laboratories in 1961. It essentially bonds two vitamin B6 compounds (pyridoxine) together with a disulfide bridge. That modification allows it to exert a potential nootropic effect. It has been shown to potentially speed up reaction time. There is evidence that it may increase ACh uptake through lipid membranes and increases cGMP levels in the brain.
