I keep saying this and I can't stress it often enough, Depression is NOT a one size fits all disease and treating it as if it is could actually be quite devastating.

I agree with the answers which recommended exercise, but please be extra careful about making huge dietary changes or taking any herbal remedies without first of all talking to a health professional.

it can be a mine field treating depression even with expert guidance, so accepting everything you read on here is really not the best way forward. left untreated or dealt with in the wrong way depression can lead to suicide in many sufferers.

And be very careful if you do decide to take a health supplement or St John's Wort because they can have serious side effects with a whole host of other medications, and certainly never ever mix St John's Wort with a prescribed Anti depressant.

The best person to talk over aspects of depression/anxiety/fatigue with is your doctor because it could be thyroid problems which a simple blood test would sort out, Depression can be caused by all manner of things not just nutritional issues. Actually the best thing to do is exercise. Exercise boosts your metabolism, giving you more energy. Not only that it releases endorphins, which is the "feel good" hormone, which can elevate your mood. excercise. your body will naturally secrete what you need to feel good... some people say st. john wort, but everyone reacts differently, if at all... I would take a serious look at all aspects of your life. Are you getting proper nutrition? Are you getting enough sleep? Are you drinking enough water? Are you drinking too much coffee or cola? Are you getting enough exercise? Do you need to cut out certain behaviors? A multivitamin and calcium supplement should be enough for you if you are getting everything else. St John's Wort is commonly used to treat mild to moderate depression.
