Dietary vitamin A is obtained from preformed vitamin A (or retinyl esters), which is found in animal foods (liver, milk, kidney, fish oil), fortified foods, and drug supplements. Although rare, vitamin A toxicity after long-term use of high-dose fish oil supplements has been reported. Such toxicity can lead to dizziness, nausea, joint pain, and skin problems.
Excessive fatty acids have been linked to insomnia. Although infrequently experienced, diarrhea is a recognized side effect of fish oil supplementation. Omega-3 fatty acid intake has not been substantially associated with oliguria.
