It's usually dosed on body weight. When we are on it we take about 17mg per day, that's one 12mg and 5mg, but if you only have the 12mg ones then start with one a day and see how you are feeling after 10 days or so. Was watching on e doctor the other day who is using it in cancer treatment starting at 1gm per day, working up to 2.5gm per day but if you don't have cancer then you don't need that much. (I am not a doctor).
