About OmegaQuant
Written by the company
OmegaQuant is an independent, CLIA-certified lab that offers nutritional & health status testing to researchers, clinicians and the public. We test:
- Omega-3 Index
- Vitamin D
- Prenatal DHA
- Mother's Milk DHA
Our goal is to offer the highest quality analytical services to researchers and to provide simple tests of nutritional status to consumers, with the ultimate purpose of advancing the science and use of nutrients to improve health.

Our Story
Dr. Bill Harris, a leading expert in omega-3 fatty acids, founded OmegaQuant in 2009. He obtained his Ph.D. in Human Nutrition from the University of Minnesota and did post-doctoral fellowships in Clinical Nutrition and Lipid Metabolism with Dr. Bill Connor at the Oregon Health Sciences University.
His interest in omega-3 fatty acids began with his postdoctoral work when he published his first study on the effects of salmon oil on serum lipids in humans (1980). Since that time he has been the recipient of five NIH grants for studies on the effects of omega-3 fatty acids (EPA and DHA) on human health.
He has more than 350 publications relating to fatty acids, including omega-3s, in medical literature and was an author on two American Heart Association scientific statements on fatty acids: “Fish Consumption, Fish Oil, Omega-3 Fatty Acids and Cardiovascular Disease” (2002), and “Omega-6 Fatty Acids and Risk for Cardiovascular Disease” (2009) both published in the journal Circulation.
Dr. Harris co-invented the Omega-3 Index in 2004 and made it commercially available to the research community and the public in 2009. To date, the Omega-3 Index has been used as the standard measure of omega-3 status in more than 200 clinical studies.
Dr. Harris is also a Professor in the Department of Medicine in the Sanford School of Medicine at the University of South Dakota.
Dr. Harris moved on as OmegaQuant’s President in late 2020 to establish the Fatty Acid Research Institute (FARI), where he will go back to his roots of conducting research on fatty acids and health.

Super easy, simple process - definitely using them again
Super easy, simple process. My Omega 3 numbers turned out to be super low (I've been a lacto-ovo vegetarian for ~20 years), and they even reached out to me to offer the opportunity to enroll in a study on a new fish oil formulation. I'll definitely be using them again, and we're going to test other members of our family as well.
