I have been reading a lot of threads on this product and some are people are taking up to 3 capsules 3 times a day and so no one has to get out the calculator that???s 9 capsules a day!!! The bottle I have says take at most 3 capsules a day. Are they just being really carful or are the people taking 9 a day just nuts. Also, how long should I stay on these, it doesn???t seem wise to be on these for a year straight.
