I have been taking omega-3 fish oil tablets for at least 15 years. In my case, the fish oil has had no discernible effect on my depression-anxiety. However, it is entirely possible, even probable, the fish oil has had other, general health benefits. For instance, my father passed away at a relatively young age. I have exceeded that age by several years, and my biomarkers are generally solid.

In your unique circumstances, dear Little Turtle, the effect of the fish oil may be more pronounced. May your "experiment" succeed!
