for me it's copper imbalance, i have ever single symptom including more freckles out of no where... for years i had my hair died a copper red and a few years later these issues popped up. i now know that red hair dies can cause copper toxicity...geez louise what's a gal to do, i was only tryin to look purdy;) anyway, i just read that clumsiness or those types of neurological issues are usually heavy metals. i used to think the heavy metal toxicity thing was a fad but boy did i learn my lesson....
