Krill Oil for Dry Eye Disease
By Marc Shomer, MD PhD
A recent study by Deinema (Ophthalmology Jan 2017)* provides strong support for the supplement Krill oil in reducing both the signs and symptoms of dry eye disease. What makes this convincing evidence is that the study was randomized, double-masked, and a placebo-controlled clinical trial. Interestingly they found superior results for Krill Oil then the Fish Oil which everyone associates with Omega 3 fatty acids. This is potentially due to the predominantly phospholipid form of Krill Oil compared to Fish Oil.
The study showed that supplementation that tear osmolarity, a measure of how concentrated the tears are, was improved in subjects receiving Omega 3’s. They also showed that Ocular Surface Disease Index which is an important measure of Dry Eye was also improved. This includes, decreased ocular redness and improved tear film stability. Markers of inflammatory molecules, specifically interleukin 17A were also reduced with supplementation. The Krill Oil group had the strongest response.
If you feel that you may suffer from dry eyes, please see your Ophthalmologist, an Eye MD (medical doctor of the eyes), for a complete eye exam and also consider adding Krill Oil to your routine (945 mg/day eicosapentaenoic acid [EPA], + 510 mg/day docosahexaenoic acid [DHA]).
