If at all your body is lacking in vitamin B-12, then only this vitamin should have been prescribed which is available under the trade name of Methycobal that contains 500mcg of B-12. You need to take Methycobal for just two months. Neurobion forte contains just 15mcg of B-12 which is not adequate to correct deficiency states. Besides Neurobion was banned several years ago; in order to evade the ban order, additional ingredients of hardly any clinical value (nicotinamide and d-panethenol) were added and the name was slightly changed to Neurobion forte. In no advanced country such a combination is permitted.
