In one 12-week study in contact lens wearers, 600 mg of DHA and 900 mg of EPA daily improved eye discomfort by 42% — which was similar to improvements noticed with corticosteroid eye drops (30). Docosahexaenoic acid, or DHA, is a polyunsaturated omega-3 fatty acid (PUFA) found throughout the body. In a recent review, seven of nine studies that tested the effects of DHA supplements in children with ADHD showed some improvement — such as with regard to attention or behavior (14).

DHA is mostly found in fatty fish, shellfish, fish oils, and algae. People with mild memory complaints or cognitive impairments may benefit from 500–1,700 mg of DHA per day to improve brain function (43, 44, 45, 46, 47, 48). Omega-3 needs vary by individual.

You should avoid taking omega-3 supplements 1–2 weeks before surgery. These parts of the brain are responsible for processing information, memories, and emotions.
