Allbee B-complex vitamins have been around since the 1960's, possibly longer than this but that is the limit of my personal knowledge of this product. They have a national drug code label (NDC Number: 36652-0677-62) which means they are recognized by the FDA. Doctors actually prescribe these vitamins for their patients although they are available without a prescription. I have been taking them off and on for many years. They help me when I am under a lot of stress. They are sometimes hard to find so I look for and order them online when I get close to running out. Nothing else works for me as well as Allbee C-800 B-complex vitamins at keeping up my strength and peace of mind.
