Has anyone had any reactions from taking too much malic acid? How much was too much for you? How would I know it's too much? What might it do to me? I just started taking it again at bedtime, and seem to wake up feeling better and more clear headed. I took another one this morning, and wonder if a third in the afternoon would be too much. I can't remember the dosage (I'm at work...) but maybe 800mg? not sure. I read about a study with malic acid and fibro, and they gave the study participants up to 2400mg a day. Seems like a lot, but what the heck do I know??? Thanks, Beth.
