VisionPro EPA/DHA/GLA supports natural tear production, healthy tear film composition and retention of eye moisture. Specifically, EPA and DHA support the coating of fluid that covers the eyes. These omega-3 fatty acids are incorporated into the lipid layer of the eye to maintain its fluidity and viscosity. By supporting the functional properties of the lipid layer, EPA and DHA promote retention of water in the underlying aqueous layer. EPA and DHA also promote healthy prostaglandin and cytokine balance to help protect the secretory function of the lacrimal glands. In addition, VisionPro EPA/DHA/GLA provides 75 mg GLA per serving from cold-pressed borage oil. Several studies have demonstrated that GLA-rich oils provide unique support for mucin production, prostaglandin balance and healthy tear film characteristics.
