Do you prefer to take B1 before or after meal? Have you noticed any difference?
Personally I prefer to take it with water about 10 minutes before mealtime. I give it a little time to dissolve inside to avoid interfering with possibly incompatible food. I read (B1 FAQ here) that such unwanted food includes any citrus fruits or juices.
Could you name any other products we should avoid together with B1? What about coffee & milk? Thanks.
