Fitness fanatic’s supplement overuse causes ALS-like symptoms: case

Sydney doctors say their 40-year-old patient developed extensive fasciculations over an eight-month period.

Doctors have traced a patient’s extensive muscle twitching, which mimicked amyotrophic lateral sclerosis, to vitamin B6 overload from workout supplements.

The 40-year-old male patient — described as a “physically fit gym enthusiast” — had no other medical problems or prescriptions when he was referred to a neuromuscular clinic with generalised fasciculations.
