I buy them separately because I feel the multi b doesn’t really work. I have been using gnc and pharmassure. I think if you buy any gnc products you have to be really careful you don’t over pay but for minerals and vitamins they seem to be getting the job done for me. They should be around $5 a bottle and they last me a long time as I only take one of each a day. I take Biotin, B6, B12. Minerals hours before in the morning, the multi mineral seems to be feeding my candida somewhat but I really don’t have a choice in the matter.
doctors best and source naturals are probably the best but I don’t usually order offline because I forget allot right before i run out. I did find an awesome store in nyc last week though with a ton of brands, Im looking forward to getting in there.
