I take fish oil and eat flaxseed. Can I overdo the omega-3 fats?
Asked by kitt52 on Mar 21, 2008 in Nutrition

I eat 1 teaspoon of flax seed and 1 teaspoon of cod liver oil every day. I am wondering if you can over do and get to much Omega 3.


In general, adults can safely take up to 20 milliliters, or 4 teaspoons, of cod liver oil and 50 grams, or 4 tablespoons, of flaxseed a day. You are taking much less than that and so you are not overdoing it.

Fish oil provides two omega-3 fatty acids, DHA and EPA, and flaxseeds are rich in another omega-3 fat, ALA. Omega-3 fats cannot be produced by the body and must be eaten in the diet. Omega-3 fats play important roles in the immune and neurological systems. Many experts recommend eating two portions of oily fish every week to get enough omega-3s. Cod liver oil also provides large amounts of vitamins A and D, which can be toxic if taken in excess. Read more about omega-3 supplements from the Nutrition Guide at
