Researchers carried out some preliminary studies using the supplemental intake of essential fatty acids, vitamin B6 and vitamin C to treat dry eyes. The rationale for this treatment was based on the biosynthesis of prostaglandin E1 (PGE1), which is necessary for acqueous tear secretion by the tear glands. Patients received 2 x 500 mg capsules of Evening Primrose Oil (omega-6), 50 mg of vitamin B6 and 1 gram of Vitamin C three times daily.

The results showed that 10 of the 17 patients had substantial improvement of symptoms and Schirmer Test in 2-6 weeks, 3 patients reported improved symptoms though without improved Schirmer testing. The authors' conclusion was that this treatment approach is effective in many cases.
