Program information

Diploma in Dietary Supplement Science

According to Gene Bruno, Provost at Huntington University of Health Sciences, “I always believed that the world of nutrition education needed an academic program in dietary supplement science, and I was now in a position to spearhead the effort to create one. To this end, I assembled a group of nutritionists, pharmacists, herbalists, biologists and dietary supplement experts to design the curriculum for a Diploma in Dietary Supplement Science (Dip.D.S.S.). It took a few years to develop and was quite a task, but in January of 2008 HUHS launched the world’s first accredited program in dietary supplement science.”
