title = "Safety of daily oral vitamin A supplementation for individuals with retinitis pigmentosa",
abstract = "Many patients with retinitis pigmentosa take 15,000 IU of vitamin A daily, but the safety of supplementation has not been well characterized. A review of the published literature shows that vitamin A supplementation at this level is safe in healthy adult men and non-pregnant women who eat a diet without excessive intake of food high in vitamin A. Annual monitoring of liver enzyme and triglyceride levels is recommended for patients receiving supplementation.",
