I've been involved in the natural health field for quite a few years now and one of the questions that people always ask me is how long it will take for a concentrated fish oil supplement to have a positive effect on their health. This is a complex matter, but basically it depends on 2 variables. The first is the quality and potency of the product and the second is the reason you're taking it.

First and foremost, you must make sure that you choose a fish oil that is very high in DHA, is molecularly distilled and is free of toxicity. As long as the product you choose is a high quality one with a high dose of DHA and EPA, then the speed with which concentrated fish oil will work for you will depend on the state of your health and on what you expect it to do for you.

If you're taking concentrated fish oil in order to lower your triglyceride or homocysteine levels, then it can be effective in as little as two weeks. In most cases, after four weeks, there are noticeable declines in triglycerides. Most issues relating to blood tests respond in a similar manner.

For diseases such as heart disease, atherosclerosis and rheumatoid arthritis, research shows that it takes about three months for the positive effects to appear. This is due to the fact that it takes your body several months to make up for all the negative effects of past dietary habits, drinking, smoking, etc...

In cases of depression, the results can vary widely. Depression is a very complex problem, which includes both psychological and organic components. In many cases, depression has been linked to DHA deficiency in the brain. In cases such as this, high doses of concentrated omega 3 have been shown to work very quickly. Other cases take more time. Regardless, depression often responds better to higher doses rather than to lower ones.

In summary, the most important thing is to choose a top-quality product and to take it consistently without giving up. If the product itself is of the highest quality, then the time it will take for it to be effective will be a lot shorter.
