Remedies include the following:
• Amino acids. Some amino acids, such as methionine or cysteine, are water-soluble and can help to regulate excessive sweating. Try taking 1 g of L-cysteine daily for three weeks. This may be combined with 500 mg of zinc acetate plus 250 mg chromium picolinate daily in divided doses up to three times a day (see “Supplement Recommendations”).
