I have been prescribing Omega 3 for my patients for years knowing the benefits in the treatment of dry eyes. As new formulas wouild come out I would always try them thinking one was better than the other. My condition would always wax and wane while I would suffer through the smell of the fish oil or the "fish burps" that came along with the capsules. I discovered PRN and 3 months after starting them I noticed significant improvement in both my eyes and skin. This was the first year I didn't go through large bottles of skin moisturizer or eye drops. I finally found a product I know works because of its high absorption and purity from being a pharmaceutical grade product. My patients and I are now sharing the benefits of PRN products.
