OK I have one in front of me...my memory was incorrect. They are white circles 8mm wide, 4mm thick and domed on BOTH sides. No markings. The reason for my concern is if they are 5mg and I take 3 a day I won't notice much until I am a few weeks in and by then I would have wasted time and money. Hopefully someone can recognize the type or else I just won't get them.
