At the 2018 American Society of Sports Medicine, there was a presentation by Dr. Chang Woock Lee of the University of Houston-Victoria. Dr. Lee has been researching muscle performance and cholesterol. As his research developed, he became interested in the micronutrients associated with cholesterol.
