Keep in mind that this hypothesis has not yet been well demonstrated scientifically, and there is a lack of solid evidence that omega 3 is effective in preventing or treating depression.
Hi, that it suddenly came out of the blue is interesting. Have you had blood tests for other possible causes such as thyroid, iron, vitamin B12, vitamin D, and folate levels? Were you on any medications when it started? Did/do you have any other medical conditions? Do you feel your current type and dose of antidepressant is effective enough? Do you feel sleepy during the day?
If your blood tests are showing no deficiencies or issues (and you should have them 6 monthly in case something develops) then I would ask for a referral to a psychiatrist to see if the diagnosis is correct and whether your meds need increasing, augmenting, or changing. There are numerous meds available and sometimes you need more than one med. For me, it was only after trying several meds and combinations that we found one that works better than the others.
