A short YouTube clip (uploaded/created by Dr. Ron Najafi) in which Robert Lustig describes how milk was historically fortified with vitamin D by irradiating milk with ultraviolet light. He attributes the 1919 discovery to Harry Steenbach at the University of Wisconsin who found that UV irradiation converted 7D hydrocholesterol in milk into vitamin D, and notes the resulting patent significantly enriched the university (alongside other profitable discoveries like Warfarin/Coumadin).
