PRN Physician Recommended Nutriceuticals PRN was founded on the idea that a nutriceutical product line, developed by leading physicians and delivered to patients in a convenient way could significantly support eye health. At PRN, we are committed to providing you with the highest quality nutriceuticals. PRN provides our customers the most scientifically–based, clean and efficacious nutritional supplements possible. The science behind our products is important to us, and so is teaching the science behind our products. Our medical team of ophthalmologists and optometrists lecture at International, National, State and Local continuing education venues to provide the most current omega-3 research available. As all of our products are based on peer-reviewed clinical evidence, we enthusiastically provide accredited continuing education courses to ensure that our doctors are current on the latest omega-3 science.
