I had hyperhidrosis from the age of 16 to the age of 56. While my hyperhidrosis was embarrassing, I had the kind that is a symptom of chronic fatigue syndrome. This kind makes you sweat, but the sweat has no scent.
At 56 I was doing a copper detox and noticed my hyperhidrosis had went away. I started checking my supplements to see which one had done this. I found two. It seems a deficiency in molybdenum can cause hyperhydrosis. For the detox I was taking 400 mcg a day. I was also taking bamboo extract to detox aluminum. Bamboo extract is high in silica. A deficiency of silica can cause hyperhidrosis. My bamboo extract supplement is 300 mg. I started doing the bamboo and molybdenum at about the same time and it was about three months of taking them that I noticed my hyperhidrosis was gone.
