Your Omega 3 Prescription

By this point, you should already know that you need more Omega 3 fatty acids into your diet.

The question is: how much?

  • A teaspoon of fish oils?
  • A tablespoon?
  • 3 pills?
  • or a great big slab of smoked salmon?

Well, according to this study, researchers believe that “a 200 mg dose of DHA per day is enough to affect biochemical markers that reliably predict cardiovascular problems, such as those related to aging, atherosclerosis, and diabetes”.

This study is the first to identify how much DHA is necessary to promote optimal heart health.

The Study

To determine the optimal dose of DHA, the researchers examined the effects of increasing doses of DHA on 12 healthy male volunteers between ages of 53 and 65. These men consumed doses of DHA at 200, 400, 800, and 1600 mg per day for two weeks for each dose amount, with DHA being the only omega-3 fatty acid in their diet. (No EPA)

Blood and urine samples were collected before and after each dose and at eight weeks after DHA supplementation stopped. The researchers then examined these samples for biochemical markers indicating the effects of each dose on the volunteers.

They found that supplementation with only 200 mg/d DHA for 2 wk induced an antioxidant effect.

They concluded that “low consumption of DHA could be an effective and nonpharmacological way to protect healthy men from platelet-related cardiovascular events”.


If this study is correct, you need only 200 mg of DHA per day to reap the cardiovascular benefits of the Omega 3 fatty acid DHA.

And how do you get 200 mg of DHA?


  1. From what I’ve come across [though I don’t have the sources offhand, but can try to look them up if anyone really wants them] the ratio of EPA and DHA can play a role in determining health outcomes as well. Eg, a higher ratio of DHA:EPA is good for fatty brain tissue, and better for men because of our lowered ability to produce DHA, etc.

    Basically, I think the study may have a fundamental flaw in that the only omega 3’s consumed were DHA. Obviously, the effect isn’t going to be negated with the addition of EPA, since they are beneficial too, but I personally feel the study would have been more comprehensive if they hadn’t left out half the equation.

    This pretty much falls under the general gripe, though, of health studies being ridiculously specific, which sometimes limits their applicability. It’s less of an issue in this case, because we know EPA is also good, so its exclusion won’t lessen the benefits. I’m just being a contrarian.

  2. Heart disease ???? I ve got the ultimate solution!!!
    Red Wine is good and excersize is good. So now I run from pub to pub every evening.
