What is the Recommended Dietary Allowance (RDA) for omega-3, 6 and 9?

The IOM has established an AI for omega-3 and omega-6, but has not established a recommendation for omega-9 fatty acids because they are made in the body and not required in the diet. Go to Food Composition > Macronutrients > Fats and Cholesterol for the DRI tables and more information about fats and fatty acids.

These resources provide more information about omega-3 and omega-6 fats:

MedlinePlus: Dietary Fats
Face the Fats (PDF | 278KB) provides a detailed listing of the amounts omega-3 fats in fish, as well as tips for consuming them if you don’t eat fish.

See also "Where can I find how much omega-3 and omega-6 fatty acids are in different foods?" under the Food Composition section of the Frequently Asked Questions.
