I am not that guy who comes with a cure twice a year but there is something you should try and is helping me: it is rosemary extract. Im taking about 120mg rosmarinic acid a day and its helping my POIS a lot. People who did not respond well to niacin should definetely try it. People with low thyroid dont respond well to niacin, but they should feel the blocking effects of rosmarinic acid.
Does it matter when you take it, day/night? Does it take some time to take effect?
If you can't find rosmarinic acid, is there an equivalent in the spice, rosemary? Make a tea with it, how much etc.?
Thanks for the heads up.
BTW, do you know of any down sides, precautions? I remember that we had problems with nutmeg if taken too much.
