backed by science

opurity™ products are designed with input from PhD ingredient specialists, MD condition specialists, and Masters-level dietitians. The President of our company is a Masters-level Registered Dietitian with three decades of experience with patients and nutrition.

Our first source for all nutritional considerations is the Dietary Reference Intakes information from the National Academy of Sciences Institute of Medicine. This provides deep information about requirements, deficiencies, tolerable upper limits and more. We also consider information from National Institutes of Health. We base every formulation decision heavily on these sources as well as on thorough reviews of clinical literature and expert input. We also stay up-to-date on condition-specific research.

Consistent with recommendations from those and other serious sources, we do not recommend or support “mega-dosing” of nutrients.

We carefully consider new research, but history shows that much of the "hot"  or "newspaper-headline" research is not as valid as that which has been proven and re-proven over time.
