Beta-Alanine, a nonessential amino acid and freely available as a nutritional supplement in many countries, has been found to suppress or significantly reduce the symptoms in many cases. Anecdotal evidence indicates that it is commonly consumed in doses of 750 mg to 2 grams before water contact. A study found that a dose of 2 grams twice per day led to a "dramatic and sustained improvement" of symptoms in a 13-year-old male patient, allowing him to comfortably shower, exercise, and swim.
