This is also a big problem for me. I tried many supps and found that if you are really depressed the natural things like st. johns wort, 5-htp etc. won't help much.

The supplements that work best for me are magnesium (megadoses), fish oil and the essential trace elements. It helps but my life still sucks, so it is not a cure for depression <img src="/ubbthreads/images/graemlins/wink.gif" alt="" />

All lot of my depression is caused by food allergies. If you get severly depressed after eating you should take hydrochloric acid and pancreatic enzymes and/or avoid food allergens.

An other thing that has been helpful(even more effective than the supps) is listing to a meditation CD (www.centerpointe.com) I could not believe it but this really helps a lot.
