Sorry I couldn't help you more. When I'm out and about I'll peek in a few stores just to check out the situation. I've found that some things I consider commonplace are not available. I had to order Colloidal Silver "under the counter" so to speak so it might be possible for you to do the same with B5, keyi ma? Or you could possibly order from a catalogue of some sort. I'll bet some healthfood stores have catalogues and will order a specific supplement for you.
