I copied and pasted this information..be concerned with the EPA, not the fish oil.
"To treat eczema, six grams of concentrated omega-3 fatty acids has been taken by mouth daily. A dose of 10 grams of fish oil has been taken by mouth for 12 weeks. The following doses have been taken by mouth: 12 capsules of fish oil daily (providing 2.0 grams of EPA plus 1.3 grams of DHA daily) or six one-gram capsules (containing 51% EPA, 32% DHA, and 3.6 international units per gram of DL-alpha-tocopherol) for 12-16 weeks. Doses of 1,800-3,060 milligrams EPA plus 1,200-1,920 milligrams of DHA has been taken by mouth."
American Heart Association recommended dosage for adults-
"500 mg/day EPA/DHA (equivalent to two servings of fish per week) for adults for cardiovascular health
1000 mg/day of Omega-3 EPA/DHA Ė patients with coronary heart disease
2000 to 4000 mg/day of Omega-3 EPA/DHA Ė patients with high triglycerides"
