I've been taking it for two months now, (1000 to 1200 mgs daily) with no impressive results. I'm SO disappointed. It helped with my IBS-like symptoms and a bit with sinus congestion. But for me, it's not worth pursuing. Just another one in a series of "things to try" THAT WORK FOR SO MANY OTHERS, but not for me! Sorry to be so negative, but can't help it right now. Every time I get excited about trying something new and it doesn't help much, I feel more hopeless. Oh well.
