Effects of fish oil on depression
How much better would it be if you could take fish oil for depression instead of antidepressants if you want to treat your depression without medication.
Good fats, including fish oil, ensure that your nerve cells in particular have a healthy membrane (the sheath that covers the cells). A healthy membrane ensures an easy passage for nutrients and natural chemicals in and out of the cells. It also ensures an efficient transmission of electrical 'messages' across all cells.
Web MD reports:
However, just because there is a deficiency, it doesn't mean that we necessarily need to supplement/overdose by buying stuff from the chemist. And in particular - we're unlikely to need to do so, if we can get the right amount from our food.
Oh... and then there's also the issue of the link between serotonin and depression, but that's for another page.
Let's see though what those benefits were thought to be...
To illustrate how closely fish oil, but in particular DHA - one of its components - is said to link with depression, have a look at this study. It reports on the link between low levels of omega-3 and suicide in US veterans.
Dr. Sears on the effects of fish oil on depression
Dr Barry Sears, who is said to have extensively researched Omega 3, describes in one of his books how close humankind came to extinction about 150,000 years ago. But then, humans began eating fish. Our modern brains and world domination as a species are supposed to be the result!
He describes in "The Omega Zone" that Eskimos have an intake of about 7g of Omega-3s every day and know nearly no depression - despite the lack of sunlight.
He also describes a link between our decline in Omega-3 intake in the last 100 years and the rise in mental problems.
Remember the link between fish oil and depression involving serotonin? Well, here's another one...
Dr. Andrew Stoll explains a bit more about why fish oil and depression are linked in his book "The Omega-3 Connection". He wrote:
How much fish oil is needed for fighting depression?
I've seen various doses prescribed by different researchers, ranging from 1 - 3g per day. However, you must discuss your intention to take fish oil for depression with your healthcare provider and read my article on the side Effects of Omega-3.
Studies on the effects of fish oil on depression
Here is a study from the American Medical Association Archives of General Psychiatry, 2002; 59:913-919. In this study, the results revealed the following:
The following is from a newsletter from food for the brain:
In short, I really want you to research the subject of fish oil and depression to ensure you do the best for your health. I so want to help you avoid taking pharmaceutical antidepressants with all their side effects.
And, please note, there's so much else you can do to deal with depression without medication.
How long before you would feel the benefits of taking fish oil for depression?
How long after you start taking fish oil for depression will you begin to feel its effects? The answer really depends on your individual make-up, just like it would with any type of medical intervention or medication.
Every person is different and you too are as unique as any star in the sky!
Having said that, you may see an improvement in as little as 3 weeks. 1g seems to do the job for most people within about 12 weeks. Dr. Barry Sears treats his patients with high doses for heavy brain deterioration (Alzheimer, dementia etc.) - he reports: with great success.
But: he is a doctor and uses a blood test to measure the needed amount of Omega-3s. Remember to read my article on omega 3 side effects.
